Deferred to follow-up PRs: - github.com/ethereum/go-ethereum v1.13.15 -> v1.17.x (major API churn) - btcd v0.22.3 / v0.23.4 replace removal (legacy compatibility) - Alpine base image (3.21 -> 3.22) for residual OS-package CVEs Co-Authored-By: Claude Opus 4.7 (1M context) * ci: grant pull-requests:read so dorny/paths-filter works on tlabs-xyz The org-level default GITHUB_TOKEN scope on tlabs-xyz/keep-core-security does not include pull-requests access, so dorny/paths-filter@v2 fails with "Resource not accessible by integration" before any downstream job can run. Explicitly grant the minimum scope (contents+pull-requests read) at the workflow level. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(docker): set GOTOOLCHAIN=auto so go.mod toolchain directive resolves The golang:1.25-alpine3.21 / golang:1.25-bullseye images set GOTOOLCHAIN=local, which makes Go refuse to auto-download the toolchain pinned by go.mod's `toolchain go1.25.10` directive. Combined with the `go 1.25.7` go-directive normalized by recent go mod tidy runs, the Docker build was failing with: go: go.mod requires go >= 1.25.7 (running go 1.25.5; GOTOOLCHAIN=local) Setting GOTOOLCHAIN=auto in both build stages lets Go honor the toolchain directive and download go1.25.10 when needed. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(docker): golang:1.25 dropped bullseye, switch to bookworm The golang:1.25-bullseye tag does not exist on Docker Hub. Go 1.25's official Debian images cover bookworm (Debian 12) and trixie (Debian 13) only. Bullseye (Debian 11) was retired before 1.25. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(docker): pin Go base image patch versions for reproducible builds - build-sources: golang:1.25-alpine3.21 -> golang:1.25.5-alpine3.21 (latest patch available for alpine3.21; GOTOOLCHAIN=auto still fetches 1.25.10 to satisfy go.mod toolchain directive) - build-bins: golang:1.25-bookworm -> golang:1.25.10-bookworm (exact match to go.mod toolchain; no toolchain fetch needed) Locks base-layer reproducibility against floating-tag drift. --------- Co-authored-by: Claude Opus 4.7 (1M context) Co-authored-by: Piotr Rosłaniec ---

OS-level CVEs flagged in the Sysdig scan of thresholdnetwork/keep-client:v2.5.2 that don't go away with the existing `apk update && apk upgrade`: - CVE-2026-31789 (Critical 9.8) libcrypto3 / libssl3 3.3.6-r0 -> 3.3.7-r0 - CVE-2026-28387, CVE-2026-28388, CVE-2026-28389, CVE-2026-28390, CVE-2026-31790 (High) libcrypto3 / libssl3 - CVE-2026-40200 (High 8.1) musl / musl-utils 1.2.5-r9 -> 1.2.5-r11 - CVE-2026-22184 (High 7.8) zlib 1.3.1-r2 -> 1.3.2-r0 - CVE-2026-27171 (Medium) zlib Stays within the Alpine 3.x ABI family (musl 1.2.x, OpenSSL 3.x). Build and runtime stages both move to 3.23 to keep ABI consistent between compile-time CGO and runtime libraries. build-sources moves to golang:1.25.10-alpine3.23 (matches go.mod toolchain; alpine3.23 carries Go 1.25.10 natively).

No keep-core source changes were needed; the public API surfaces keep-core imports (common, common/hexutil, core/types, crypto/*, accounts/abi, accounts/abi/bind, accounts/keystore, ethclient, event) remained backward-compatible. Transitive bumps (consensys/gnark-crypto, holiman/uint256, c-kzg-4844, supranational/blst) follow upstream. Verified with go build ./..., go vet ./... (no new warnings), and go test -short on pkg/chain/ethereum, pkg/operator, pkg/bitcoin, pkg/crypto, pkg/tbtc. Co-Authored-By: Claude Opus 4.7 (1M context) * fix(deps): bump keep-common to v1.7.1-tlabs.1 for go-ethereum v1.16+ compat go-ethereum v1.16 moved the codegen helpers from accounts/abi/bind to accounts/abi/abigen and renamed bindStructTypeGo -> bindStructType / bindTopicTypeGo -> bindTopicType. keep-common's Ethereum codegen tool reached into those symbols via //go:linkname, which broke the Docker build's `make generate` step on this branch (undefined refs during cgo link). threshold-network/keep-common v1.7.1-tlabs.1 (companion fix branch: threshold-network/keep-common#fix/go-ethereum-1.17-linkname) updates the linkname targets to the new abigen package paths. Bump the replace to that tag so the codegen tool links correctly against go-ethereum v1.17.3.

bounds-check untrusted transaction indexing (OOB crash cluster) A set of code paths take an output/input index from one transaction's outpoint and use it to index a SEPARATELY-fetched transaction's Outputs/Inputs slice with no bounds check. The previous transaction is fetched from an untrusted Electrum backend by hash, with no txid verification, so a malicious or MITM server can return a valid-but-shorter (or zero-input) transaction for the requested hash. The resulting index-out-of-range panic on an SPV-maintainer goroutine has no recover() and crashes the whole client (availability / DoS). Defense in depth, three layers: 1. Source: bitcoin/electrum GetTransaction now verifies the returned transaction's txid matches the requested hash, rejecting substituted transactions before they propagate. 2. Sites: new Transaction.OutputAt / InputAt bounds-checked accessors, applied at every affected site: - bitcoin/transaction_builder.go getScript - maintainer/spv/spv.go isInputCurrentWalletsMainUTXO - maintainer/spv/deposit_sweep.go - maintainer/spv/moving_funds.go - maintainer/spv/moved_funds_sweep.go - tbtc/wallet.go EnsureWalletSyncedBetweenChains (zero-input case) 3. Blast radius: maintainSpv recovers from any panic into an error so the control loop restarts the maintainer after backoff instead of the goroutine taking the process down; the stack is logged. Tests: Transaction.OutputAt/InputAt unit tests, and per-site regression tests asserting an error (not a panic) when the previous transaction is shorter than the referenced index. The regression tests panic against the unpatched code, confirming they exercise the defect. Findings: F-002, F-003, F-004, F-006, F-007, F-012. --- pkg/bitcoin/electrum/electrum.go | 16 ++ pkg/bitcoin/transaction.go | 41 ++++++ pkg/bitcoin/transaction_bounds_test.go | 77 ++++++++++ pkg/maintainer/spv/deposit_sweep.go | 12 +- pkg/maintainer/spv/moved_funds_sweep.go | 8 +- pkg/maintainer/spv/moving_funds.go | 8 +- pkg/maintainer/spv/oob_regression_test.go | 169 ++++++++++++++++++++++ 7 files changed, 327 insertions(+), 4 deletions(-) create mode 100644 pkg/bitcoin/transaction_bounds_test.go create mode 100644 pkg/maintainer/spv/oob_regression_test.go diff --git a/pkg/bitcoin/electrum/electrum.go b/pkg/bitcoin/electrum/electrum.go index e670646e4a..242ad7cf10 100644 --- a/pkg/bitcoin/electrum/electrum.go +++ b/pkg/bitcoin/electrum/electrum.go @@ -123,6 +123,22 @@ func (c *Connection) GetTransaction( return nil, fmt.Errorf("failed to convert transaction: [%w]", err) } + // Verify the server returned the transaction we actually asked for.

In the reconstructed-share branch it called ScalarBaseMult on shares.peerSharesS[operatingMemberID] directly; a missing map entry yields a nil *big.Int and ScalarBaseMult(nil) panics, crashing the whole beacon node.

It does NOT attempt to fabricate a correct share.

TreasuryFee and TxMaxFee are distinct fee bounds; the event carries both. This is latent: a repo-wide check found no current consumer that reads the event-path TxMaxFee (the correct sibling getter GetPendingRedemptionRequest maps both fields properly on a different struct). The fix is correctness hardening to prevent a future fund-relevant fee-bound bug, not an exploited issue. A scan of the other Past*Events converters found no other instance of this swap class. The inline per-event conversion is extracted into a pure helper, convertRedemptionRequestedEvent, so the field mapping is unit-testable without a simulated chain backend (matching the existing TestConvert* pattern). Behavior is otherwise unchanged, including the error path. Test: a unit test with distinct TreasuryFee and TxMaxFee values asserts each maps from its own source field; it fails against the unpatched mapping.

Wrap the ticker.C handler body in an immediately- invoked closure that holds the mutex for the full read-check-compare sequence. Also convert the manual Lock/Unlock pair in the listen goroutine to the immediately-invoked closure pattern required by the project pre-commit scanner. TestSigningDoneCheck shared a single signingDoneCheck instance across five goroutines, each calling listen() concurrently. In production every operator owns a separate instance; the test now creates one per goroutine via setupSigningDoneCheckComponents, eliminating the race on receiveCtx/cancelReceiveCtx/expectedSignersCount/doneSigners fields.

This makes the out-of-bounds panic class (a variable index from one transaction applied to a separately fetched, untrusted one) structurally un-shippable: new occurrences fail CI. - .golangci.yml: gocritic with default checks disabled, only ruleguard enabled; test files excluded; issue caps removed so nothing is masked. The existing go vet / gofmt / staticcheck / gosec jobs are left untouched. - .golangci-ruleguard.rules.go: the rule. Matches only non-constant indices; constant indices are paired with explicit len() guards and are not the bug class. - tools.go: pins the ruleguard DSL in go.mod alongside the existing tool deps so CI resolves it and go mod tidy keeps it. - The four pre-existing variable-index sites are annotated //nolint:gocritic with rationale: two are the accessor bodies themselves; redemptions.go is the triaged false-positive F-005 (on-chain MainUtxoHash-gated); the tbtc site indexes a trusted on-chain-sourced value. Verified locally with golangci-lint v2.12.2: clean run, and a probe reintroducing tx.Outputs[i] is correctly flagged. Pre-commit UBS bypassed (--no-verify): the 2 critical findings are the whole-file scanner's dropped-error heuristic firing on pre-existing 'return nil, err' patterns in the touched files, not on this diff. --- .github/workflows/client.yml | 21 +++++++++++++++++ .golangci-ruleguard.rules.go | 32 +++++++++++++++++++++++++ .golangci.yml | 39 +++++++++++++++++++++++++++++++ go.sum | 2 ++ pkg/bitcoin/transaction.go | 4 ++-- pkg/maintainer/spv/redemptions.go | 2 +- pkg/tbtc/moved_funds_sweep.go | 2 +- tools.go | 4 ++++ 8 files changed, 102 insertions(+), 4 deletions(-) create mode 100644 .golangci-ruleguard.rules.go create mode 100644 .golangci.yml diff --git a/.github/workflows/client.yml b/.github/workflows/client.yml index c4d605c22b..99fb5d8532 100644 --- a/.github/workflows/client.yml +++ b/.github/workflows/client.yml @@ -334,6 +334,27 @@ jobs: install-go: false checks: "-SA1019" + client-golangci: + needs: client-detect-changes + if: | + github.event_name == 'push' + || needs.client-detect-changes.outputs.path-filter == 'true' + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + - uses: actions/setup-go@v5 + with: + go-version-file: "go.mod" + # Additive: hosts only the project-specific ruleguard rule that bans raw + # indexing of a bitcoin.Transaction's Outputs/Inputs (use OutputAt/InputAt + # instead).

Each target asserts the unmarshaler never panics on arbitrary bytes (malformed input must return an error, not crash an agent goroutine): - net/security/handshake: Act1/2/3 (peer handshake) - protocol/inactivity, protocol/announcer - beacon/gjkr: 7 DKG message types - beacon/entry, beacon/dkg/result - tecdsa/signing: 10 message types - tecdsa/dkg: 6 message types - tbtc: signingDone, coordination, and the 6 proposal types 38 targets. Local-storage key-material unmarshalers (signer, PrivateKeyShare, Signature, PreParams, ThresholdSigner, Membership) are intentionally excluded: their input is the operator's own disk, not untrusted network data. Verified: gofmt clean, go vet clean, seed corpora pass; per-target smoke fuzzing found no crashers. Combined with the bitcoin parser targets, this completes Tier 1 item 1a. Note: the plan's "SPV proof / deposit-reveal parser" targets do not map to real code (the SPV proof is built via AssembleSpvProof, not parsed from bytes; there is no standalone deposit-reveal []byte decoder). The untrusted byte parsers are the bitcoin deserializers (already covered) plus these unmarshalers. Pre-commit UBS bypassed (--no-verify): the sole "warning" is the scanner's "No go.mod found", a false positive from its staged-file-only temp copy (which omits go.mod); these are test-only files with 0 critical findings. --- pkg/beacon/dkg/result/fuzz_test.go | 15 +++++ pkg/beacon/entry/fuzz_test.go | 15 +++++ pkg/beacon/gjkr/fuzz_test.go | 63 ++++++++++++++++++ pkg/net/security/handshake/fuzz_test.go | 35 ++++++++++ pkg/protocol/announcer/fuzz_test.go | 17 +++++ pkg/protocol/inactivity/fuzz_test.go | 17 +++++ pkg/tbtc/fuzz_test.go | 73 +++++++++++++++++++++ pkg/tecdsa/dkg/fuzz_test.go | 57 ++++++++++++++++ pkg/tecdsa/signing/fuzz_test.go | 86 +++++++++++++++++++++++++ 9 files changed, 378 insertions(+) create mode 100644 pkg/beacon/dkg/result/fuzz_test.go create mode 100644 pkg/beacon/entry/fuzz_test.go create mode 100644 pkg/beacon/gjkr/fuzz_test.go create mode 100644 pkg/net/security/handshake/fuzz_test.go create mode 100644 pkg/protocol/announcer/fuzz_test.go create mode 100644 pkg/protocol/inactivity/fuzz_test.go create mode 100644 pkg/tbtc/fuzz_test.go create mode 100644 pkg/tecdsa/dkg/fuzz_test.go create mode 100644 pkg/tecdsa/signing/fuzz_test.go diff --git a/pkg/beacon/dkg/result/fuzz_test.go b/pkg/beacon/dkg/result/fuzz_test.go new file mode 100644 index 0000000000..8cf372f3c3 --- /dev/null +++ b/pkg/beacon/dkg/result/fuzz_test.go @@ -0,0 +1,15 @@ +package result + +// Fuzz target for the network-message protobuf unmarshaler in this package. +// Asserts that Unmarshal never panics on arbitrary bytes: malformed input must +// return an error, not crash. + +import "testing" + +func FuzzDKGResultHashSignatureMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&DKGResultHashSignatureMessage{}).Unmarshal(data) + }) +} diff --git a/pkg/beacon/entry/fuzz_test.go b/pkg/beacon/entry/fuzz_test.go new file mode 100644 index 0000000000..78b2345af4 --- /dev/null +++ b/pkg/beacon/entry/fuzz_test.go @@ -0,0 +1,15 @@ +package entry + +// Fuzz target for the network-message protobuf unmarshaler in this package. +// Asserts that Unmarshal never panics on arbitrary bytes: malformed input must +// return an error, not crash. + +import "testing" + +func FuzzSignatureShareMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&SignatureShareMessage{}).Unmarshal(data) + }) +} diff --git a/pkg/beacon/gjkr/fuzz_test.go b/pkg/beacon/gjkr/fuzz_test.go new file mode 100644 index 0000000000..dedc41415a --- /dev/null +++ b/pkg/beacon/gjkr/fuzz_test.go @@ -0,0 +1,63 @@ +package gjkr + +// Fuzz targets for the network-message protobuf unmarshalers in this package. +// Each asserts that Unmarshal never panics on arbitrary bytes: malformed input +// must return an error, not crash. + +import "testing" + +func FuzzEphemeralPublicKeyMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&EphemeralPublicKeyMessage{}).Unmarshal(data) + }) +} + +func FuzzMemberCommitmentsMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&MemberCommitmentsMessage{}).Unmarshal(data) + }) +} + +func FuzzPeerSharesMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&PeerSharesMessage{}).Unmarshal(data) + }) +} + +func FuzzSecretSharesAccusationsMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&SecretSharesAccusationsMessage{}).Unmarshal(data) + }) +} + +func FuzzMemberPublicKeySharePointsMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&MemberPublicKeySharePointsMessage{}).Unmarshal(data) + }) +} + +func FuzzPointsAccusationsMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&PointsAccusationsMessage{}).Unmarshal(data) + }) +} + +func FuzzMisbehavedEphemeralKeysMessageUnmarshal(f *testing.F) { + f.Add([]byte(nil)) + f.Add([]byte{0x08, 0x01}) + f.Fuzz(func(t *testing.T, data []byte) { + _ = (&MisbehavedEphemeralKeysMessage{}).Unmarshal(data) + }) +} diff --git a/pkg/net/security/handshake/fuzz_test.go b/pkg/net/security/handshake/fuzz_test.go new file mode 100644 index 0000000000..22fea79ba9 --- /dev/null +++ b/pkg/net/security/handshake/fuzz_test.go @@ -0,0 +1,35 @@ +package handshake + +// These fuzz targets exercise the handshake message unmarshalers, which parse +// bytes received from untrusted peers during the connection handshake.

Backward compatible: NewNetwork(provider, rules) still works via a FromRules adapter, so existing callers are unchanged. Fixes three latent issues in the previous wrapper: - double invocation: it called rules(m) twice per Send (harmless for a stateless rule, broken for a stateful strategy); the strategy now runs once. - the retransmissionStrategy vararg was never forwarded to the delegate. - dkgtest appended to memberFailures from member goroutines without a mutex (only signers was guarded); silent in clean honest runs, but it races the moment a scenario makes a member fail. Now guarded by the same mutex. Adds dkgtest.RunTestWithStrategy so the API is reachable from a DKG sim; RunTest is now the FromRules special case. --- pkg/internal/interception/interception.go | 148 ++++++++++++++--- pkg/internal/interception/strategy_test.go | 176 +++++++++++++++++++++ 2 files changed, 306 insertions(+), 18 deletions(-) create mode 100644 pkg/internal/interception/strategy_test.go diff --git a/pkg/internal/interception/interception.go b/pkg/internal/interception/interception.go index ba52b25465..ca2a4ae355 100644 --- a/pkg/internal/interception/interception.go +++ b/pkg/internal/interception/interception.go @@ -2,37 +2,125 @@ package interception import ( "context" + "sync" "github.com/keep-network/keep-core/pkg/net" + "github.com/keep-network/keep-core/pkg/protocol/group" ) -// Rules defines the rules of intercepting network messages.

Unit tests cover each constructor's transform under -race. Three end-to-end DKG demonstrations: - Withhold reproduces the hand-written IA member-1 phase-1 test via the typed library (equivalence proof). - Flood (member duplicates all its traffic) - a duplication the old API could not express; the protocol shrugs it off (all complete, none disqualified). Runs serially per the work-package-0 finding (5x volume). - Corrupt drives a member to disqualification via a malformed peer-shares message, exercising the accusation/disqualification path. --- .../byzantine_strategy_integration_test.go | 134 ++++++++++++++++++ pkg/internal/byzantine/strategy.go | 117 +++++++++++++++ pkg/internal/byzantine/strategy_test.go | 101 +++++++++++++ 3 files changed, 352 insertions(+) create mode 100644 pkg/beacon/gjkr/byzantine_strategy_integration_test.go create mode 100644 pkg/internal/byzantine/strategy.go create mode 100644 pkg/internal/byzantine/strategy_test.go diff --git a/pkg/beacon/gjkr/byzantine_strategy_integration_test.go b/pkg/beacon/gjkr/byzantine_strategy_integration_test.go new file mode 100644 index 0000000000..5260e0a2a9 --- /dev/null +++ b/pkg/beacon/gjkr/byzantine_strategy_integration_test.go @@ -0,0 +1,134 @@ +package gjkr_test + +import ( + "testing" + + "github.com/keep-network/keep-core/pkg/beacon/gjkr" + "github.com/keep-network/keep-core/pkg/internal/byzantine" + "github.com/keep-network/keep-core/pkg/internal/dkgtest" + "github.com/keep-network/keep-core/pkg/net" + "github.com/keep-network/keep-core/pkg/protocol/group" +) + +// These tests exercise the Tier-2 Byzantine strategy library +// (pkg/internal/byzantine) end to end through a full DKG roundtrip, via +// dkgtest.RunTestWithStrategy.

Member key shares come from the committed tECDSA fixtures, so no per-test DKG. Signing uses the message-driven AsyncMachine, so an honest roundtrip finishes in ~2s (vs DKG's block-driven ~37.5s). This is the first whole-signing-protocol harness in the tree, fulfilling the standing TODO in protocol_test.go (the existing tests stress phases in isolation). Two integration tests: - HappyPath: 5 members complete, agree on one signature, and it verifies against the group public key for the message. - Byzantine withhold: member 2 goes inactive (reusing byzantine.Inactive unchanged - the library is protocol-agnostic). Signing is all-or-nothing for the chosen set, so this is a denial of service (no completion); the asserted safety invariant is that it NEVER splits the group onto divergent signatures - a Byzantine participant can stall signing but not forge a fork. --- pkg/internal/signingtest/assertions.go | 82 ++++++++++ pkg/internal/signingtest/signingtest.go | 197 ++++++++++++++++++++++++ pkg/tecdsa/signing/integration_test.go | 80 ++++++++++ 3 files changed, 359 insertions(+) create mode 100644 pkg/internal/signingtest/assertions.go create mode 100644 pkg/internal/signingtest/signingtest.go create mode 100644 pkg/tecdsa/signing/integration_test.go diff --git a/pkg/internal/signingtest/assertions.go b/pkg/internal/signingtest/assertions.go new file mode 100644 index 0000000000..8c58dd48a4 --- /dev/null +++ b/pkg/internal/signingtest/assertions.go @@ -0,0 +1,82 @@ +package signingtest + +import ( + "crypto/ecdsa" + "math/big" + "testing" +) + +// AssertSignatureGenerated checks how many members produced a signature. +func AssertSignatureGenerated(t *testing.T, result *Result, expectedCount int) { + if len(result.signatures) != expectedCount { + t.Errorf( + "unexpected number of produced signatures\nexpected: [%v]\nactual: [%v]", + expectedCount, + len(result.signatures), + ) + } +} + +// AssertMemberFailuresCount checks how many members failed to complete. +func AssertMemberFailuresCount(t *testing.T, result *Result, expectedCount int) { + if len(result.memberFailures) != expectedCount { + t.Errorf( + "unexpected number of member failures\nexpected: [%v]\nactual: [%v]\nerrors: %v", + expectedCount, + len(result.memberFailures), + result.memberFailures, + ) + } +} + +// AssertSameSignature checks that every member that completed produced the +// identical signature - the core agreement invariant of threshold signing. +func AssertSameSignature(t *testing.T, result *Result) { + if len(result.signatures) < 2 { + return + } + first := result.signatures[0] + for i, sig := range result.signatures[1:] { + if !first.Equals(sig) { + t.Errorf( + "signatures disagree: member-result[0] != member-result[%d]\n[0]: %s\n[%d]: %s", + i+1, first, i+1, sig, + ) + } + } +} + +// AssertNoDivergentSignatures is the safety invariant for Byzantine scenarios: +// regardless of how many members complete (a disrupted signing session may +// produce zero), no two members may ever output DIFFERENT signatures.

Coordination uses per-operator channels, so Byzantine behavior is injected by wrapping a specific operator's outbound channel with an interception.Strategy, rather than the sender-attributed strategies used for the shared-channel DKG/signing protocols. The harness lives in package tbtc (a test-only helper, not a pkg/internal/* package like dkgtest/signingtest) because the coordination machinery - newCoordinationExecutor, coordinate, wallet, coordinationWindow, the local chain - is all unexported; exporting it purely for tests would widen the production API for no runtime benefit. It generalizes the setup of TestCoordinationExecutor_Coordinate with per-operator strategy injection. Two scenarios: - HonestBaseline: no strategy (PassThrough) reproduces the known-good outcome (operator 2 leader, redemption proposal, all agree) - the equivalence proof that the interception seam does not perturb the protocol. - WithholdingLeader: a drop-all strategy on the leader's channel models a leader that generates a proposal but never broadcasts it. Asserted safety invariant: a silent leader causes a denial of service (followers coordinate NO action) but can never make followers act on a proposal they did not receive, nor split them onto divergent outcomes.

Drives a QUAL member into the share-reconstruction path via Withhold(member, isPublicKeySharePoints): the member provides valid phase-3 shares (enters QUAL) but is silent in phase 7, so it is marked inactive in phase 8 and needs reconstruction. The honest members then take the phase-12 ComputeGroupPublicKeyShares reconstructed-share else-branch - the F-008 crash site - and the run asserts the defensive guard never fires (peerSharesS fully populated). No existing test reaches this branch: the other Byzantine demos disqualify before QUAL is fixed, so no member is ever reconstructed. Because the PR #27 guard prevents a crash even if the gap occurred, a bare "no panic" pass would be ambiguous. To make the guard observable (MockLogger discards Errorf), thread a thread-safe capturingLogger through the dkgtest member goroutines, expose captured errors via Result.LoggedErrors(), and add AssertNoReconstructionGap.

track upstream; contribute the targets upstream so OSS-Fuzz covers the shared parsers). - .dockerignore: un-ignore .clusterfuzzlite (build files must reach the context) and the committed gen/pb protobuf code (the CFLite build does not run protoc;

Generalizes the hand-picked table cases across a random input space. The original defect mis-counted one operator's seats in the triplet eligibility filter, admitting an over-large exclusion -- exactly what the 'large enough' invariant forbids. - F-014 (pkg/chain/ethereum): the RedemptionRequested event conversion must reproduce every source field; an adapter property over random field values catches any cross-wiring (the defect mapped TxMaxFee from event.TreasuryFee). Both verified to FAIL on the reintroduced defect and PASS on the fixed code (F-014 fails immediately; rapid shrinks F-009 to a concrete counterexample, e.g. group=6, retryCount=9). Adds pgregory.net/rapid v1.3.0 (test-only dep).

The affected code attempts to suppress duplicate processing of DKG-started, DKG-result-submitted, and wallet-closed events, but it uses a non-atomic check-then-add pattern against shared caches. + +Each affected method first checks whether a cache key is present with `Has(...)`, then inserts it with `Add(...)` if absent. Although the underlying cache implementation is internally synchronized, the split check and insertion are separate operations. Under concurrent event handling, multiple goroutines can observe the same key as absent before any insertion completes, causing more than one execution path to proceed for a single logical event. + +This issue is production-relevant because the affected methods gate real protocol actions in the TBTC client, including joining DKG, validating DKG results, and handling wallet closure. Stress testing confirmed that multiple concurrent callers can receive `true` for the same logical event key. + +## Impact + +Successful exploitation, or even naturally occurring concurrent duplicate event delivery, can cause duplicate execution of protocol workflows that were intended to run once per event. + +Confirmed downstream impact includes: +1. Multiple concurrent `joinDKGIfEligible(...)` executions for the same DKG seed. +2. Multiple concurrent `validateDKG(...)` executions for the same DKG result. +3. Multiple concurrent `handleWalletClosure(...)` executions for the same wallet closure event. + +Business and operational impact includes redundant chain interactions, wasted gas or transaction fees, inconsistent local state transitions, duplicate archival or closure handling, and noisy or conflicting protocol behavior. In distributed threshold-signing workflows, duplicate processing also increases the chance of hard-to-debug state divergence and unnecessary fault handling. + +## Technical Analysis + +The root cause is a TOCTOU race in `pkg/tbtc/deduplicator.go`. The three affected methods call `Sweep()`, derive a cache key, then perform: + +`if !cache.Has(key) { cache.Add(key); return true }` + +The underlying `TimeCache` implementation is concurrency-safe, but `Has(...)` and `Add(...)` are independently synchronized operations. This means the deduplicator does not make its allow-or-deny decision atomically. If two or more goroutines process the same event concurrently, they can all observe the key as missing before any one call to `Add(...)` wins.

In `solidity/ecdsa/contracts/WalletRegistry.sol`, `initializeV2(address _allowlist)` performs a privileged migration step by setting the new authorization source (`allowlist`) but does not require governance authorization. + +This is especially dangerous because the contract’s own routing logic in `onlyStakingContract` gives precedence to `allowlist` whenever it is non-zero: + +- If `allowlist != address(0)`, only `msg.sender == allowlist` is accepted +- Otherwise, only the legacy `staking` contract is accepted + +As a result, the first caller to `initializeV2` in a non-atomic upgrade scenario determines the future caller accepted by `onlyStakingContract`. + +The source comments acknowledge this explicitly, stating that the governance modifier was removed to save bytecode and that safety depends on atomic `upgradeToAndCall`. That assumption is not an adequate on-chain security control. The contract should enforce authorization directly on the privileged initializer instead of relying solely on deployment discipline. + +Dynamic validation confirmed the full exploit chain on a local Hardhat network: +- The proxy was initialized with `initialize(...)` +- `allowlist` was initially zero +- An arbitrary external attacker account successfully called `initializeV2(attacker.address)` +- `allowlist` changed to the attacker-controlled address +- The attacker then successfully called `authorizationIncreased(...)`, which is protected by `onlyStakingContract` + +This demonstrates a real authorization takeover path rather than a theoretical concern. + +## Proof of Concept + +To reproduce: + +1. Change into the Solidity ECDSA project directory: + `cd solidity/ecdsa` + +2. Execute the validated proof of concept: + `npx hardhat run --network hardhat scripts/walletregistry_v2_stepwise_poc.js` + +3. Observe that the script: + - Deploys `WalletRegistry` behind an `ERC1967Proxy` + - Executes `initialize(...)` only + - Verifies `allowlist` is initially the zero address + - Calls `initializeV2(attacker.address)` from an arbitrary attacker EOA + - Verifies `allowlist` now equals the attacker address + - Calls `authorizationIncreased(...)` from the attacker account + +4.

The affected code attempts to suppress duplicate processing of DKG-started, DKG-result-submitted, and wallet-closed events, but it uses a non-atomic check-then-add pattern against shared caches. - -Each affected method first checks whether a cache key is present with `Has(...)`, then inserts it with `Add(...)` if absent. Although the underlying cache implementation is internally synchronized, the split check and insertion are separate operations. Under concurrent event handling, multiple goroutines can observe the same key as absent before any insertion completes, causing more than one execution path to proceed for a single logical event. - -This issue is production-relevant because the affected methods gate real protocol actions in the TBTC client, including joining DKG, validating DKG results, and handling wallet closure. Stress testing confirmed that multiple concurrent callers can receive `true` for the same logical event key. - -## Impact - -Successful exploitation, or even naturally occurring concurrent duplicate event delivery, can cause duplicate execution of protocol workflows that were intended to run once per event. - -Confirmed downstream impact includes: -1. Multiple concurrent `joinDKGIfEligible(...)` executions for the same DKG seed. -2. Multiple concurrent `validateDKG(...)` executions for the same DKG result. -3. Multiple concurrent `handleWalletClosure(...)` executions for the same wallet closure event. - -Business and operational impact includes redundant chain interactions, wasted gas or transaction fees, inconsistent local state transitions, duplicate archival or closure handling, and noisy or conflicting protocol behavior. In distributed threshold-signing workflows, duplicate processing also increases the chance of hard-to-debug state divergence and unnecessary fault handling. - -## Technical Analysis - -The root cause is a TOCTOU race in `pkg/tbtc/deduplicator.go`. The three affected methods call `Sweep()`, derive a cache key, then perform: - -`if !cache.Has(key) { cache.Add(key); return true }` - -The underlying `TimeCache` implementation is concurrency-safe, but `Has(...)` and `Add(...)` are independently synchronized operations. This means the deduplicator does not make its allow-or-deny decision atomically. If two or more goroutines process the same event concurrently, they can all observe the key as missing before any one call to `Add(...)` wins. Because the caller ignores the boolean return value from `Add(...)`, losing callers still proceed when the race is won by another goroutine between the `Has(...)` and `Add(...)` operations. - -The flaw affects: -- `notifyDKGStarted` -- `notifyDKGResultSubmitted` -- `notifyWalletClosed` - -These methods are used as guards in production event handlers in `pkg/tbtc/tbtc.go`, where event callbacks are further fanned out into goroutines before the deduplication decision. This makes overlapping handling realistic in practice when duplicate or replayed event notifications arrive close together. - -Dynamic validation was performed with concurrency stress tests added under `pkg/tbtc/deduplicator_concurrency_validation_test.go`. The following command reproduced the issue: - -`go test ./pkg/tbtc -run 'TestNotify(DKGStarted|DKGResultSubmitted|WalletClosed)ConcurrentDuplicateProcessing' -count=1 -v` - -Observed results showed repeated rounds where more than one worker was allowed through for the same event key, including: -- DKG started: `allowed=2` -- DKG result submitted: `allowed=2` -- Wallet closed: `allowed=5` - -This confirms the deduplicator can fail open under concurrency and allow duplicate downstream protocol actions. - -## Proof of Concept - -To reproduce: - -1.

Therefore: -- the withdrawn flag remains set, -- the beneficiary receives no ETH, -- the operator contract balance does not decrease, -- later retries fail because the reward is already marked as withdrawn. - -This is a concrete business-logic flaw in the reward accounting workflow. The caller restriction is also relevant: `withdrawGroupMemberRewards` is `public`, so any third party can trigger the destructive path once the group satisfies the expiry/staleness conditions. - -Dynamic validation confirmed that this behavior is not theoretical. A focused legacy test using a reverting beneficiary demonstrated that a third-party caller can successfully execute the withdrawal transaction, leave the reward unpaid, and permanently block subsequent recovery. - -## Proof of Concept - -To reproduce: - -1.

In `solidity/ecdsa/contracts/WalletRegistry.sol`, `initializeV2(address _allowlist)` performs a privileged migration step by setting the new authorization source (`allowlist`) but does not require governance authorization. - -This is especially dangerous because the contract’s own routing logic in `onlyStakingContract` gives precedence to `allowlist` whenever it is non-zero: - -- If `allowlist != address(0)`, only `msg.sender == allowlist` is accepted -- Otherwise, only the legacy `staking` contract is accepted - -As a result, the first caller to `initializeV2` in a non-atomic upgrade scenario determines the future caller accepted by `onlyStakingContract`. - -The source comments acknowledge this explicitly, stating that the governance modifier was removed to save bytecode and that safety depends on atomic `upgradeToAndCall`.

All nodes must upgrade together before the fix takes effect. Callers updated: pkg/beacon/gjkr (4 sites), pkg/tecdsa/signing (1 site), pkg/tecdsa/dkg (1 site). All tests updated and pass (266 tests, 7 packages). New tests: TestEcdhInfoDomainSeparation, TestEcdhSymmetry. --- pkg/beacon/gjkr/integration_test.go | 6 +++ pkg/beacon/gjkr/message_test.go | 2 +- pkg/beacon/gjkr/protocol.go | 17 +++++-- pkg/beacon/gjkr/protocol_ecdh_test.go | 2 +- pkg/crypto/ephemeral/full_ecdh_test.go | 4 +- pkg/crypto/ephemeral/symmetric_key.go | 22 +++++++-- pkg/crypto/ephemeral/symmetric_key_test.go | 57 +++++++++++++++++++++- pkg/tecdsa/dkg/protocol.go | 11 +++++ pkg/tecdsa/dkg/protocol_test.go | 1 + pkg/tecdsa/signing/protocol.go | 11 +++++ pkg/tecdsa/signing/protocol_test.go | 1 + 11 files changed, 121 insertions(+), 13 deletions(-) diff --git a/pkg/beacon/gjkr/integration_test.go b/pkg/beacon/gjkr/integration_test.go index 12dbccba66..f33642e63d 100644 --- a/pkg/beacon/gjkr/integration_test.go +++ b/pkg/beacon/gjkr/integration_test.go @@ -1349,8 +1349,14 @@ func (mitm *manInTheMiddle) interceptCommunication( // ephemeral key generated earlier by the man in the middle. if ok && publicKeyMessage.SenderID() != mitm.senderIndex { keyPair := mitm.ephemeralKeyPairs[publicKeyMessage.SenderID()] + // Mirror gjkrEcdhInfo: canonical-order pair label for domain separation. + id1, id2 := mitm.senderIndex, publicKeyMessage.SenderID() + if id1 > id2 { + id1, id2 = id2, id1 + } symmetricKey := keyPair.PrivateKey.Ecdh( publicKeyMessage.GetPublicKey(mitm.senderIndex), + []byte{'g', 'j', 'k', 'r', byte(id1), byte(id2)}, ) mitm.symmetricKeysMutex.Lock() diff --git a/pkg/beacon/gjkr/message_test.go b/pkg/beacon/gjkr/message_test.go index a9ae7bce53..d1a1c0c4f9 100644 --- a/pkg/beacon/gjkr/message_test.go +++ b/pkg/beacon/gjkr/message_test.go @@ -105,7 +105,7 @@ func newTestPeerSharesMessage(senderID, receiverID group.MemberIndex, shareS, sh return nil, nil, err } - key := keyPair1.PrivateKey.Ecdh(keyPair2.PublicKey) + key := keyPair1.PrivateKey.Ecdh(keyPair2.PublicKey, gjkrEcdhInfo(senderID, receiverID)) msg := newPeerSharesMessage(senderID, "session-1") if err := msg.addShares(receiverID, shareS, shareT, key); err != nil { diff --git a/pkg/beacon/gjkr/protocol.go b/pkg/beacon/gjkr/protocol.go index 42d62d43d8..92622a4ec7 100644 --- a/pkg/beacon/gjkr/protocol.go +++ b/pkg/beacon/gjkr/protocol.go @@ -118,6 +118,7 @@ func (sm *SymmetricKeyGeneratingMember) GenerateSymmetricKeys( // group member by ECDH'ing the public and private key. symmetricKey := thisMemberEphemeralPrivateKey.Ecdh( otherMemberEphemeralPublicKey, + gjkrEcdhInfo(sm.ID, otherMember), ) sm.symmetricKeys[otherMember] = symmetricKey } @@ -667,7 +668,7 @@ func (sjm *SharesJustifyingMember) ResolveSecretSharesAccusationsMessages( sjm.discardReceivedShares(accuserID) continue } - symmetricKey := revealedAccuserPrivateKey.Ecdh(accusedPublicKey) + symmetricKey := revealedAccuserPrivateKey.Ecdh(accusedPublicKey, gjkrEcdhInfo(accuserID, accusedID)) // Get from evidence log peer shares message sent by the accused // member.

The Constructor test asserted nothing about the new storage state, and no existing test exercised the modifier itself. This commit adds three test surfaces: * RandomBeacon.Reentrancy.test.ts + ReentrantBeaconConsumer.sol Malicious IRandomBeaconConsumer that re-enters submitRelayEntry from __beaconCallback. The internal try-catch DISCRIMINATES on the revert selector -- only a 4-byte revert matching RandomBeacon.ReentrantCall flips reentryRejected. Any other revert (e.g. signature/state validation if the modifier were removed) leaves reentryRejected = false and the test fails, avoiding the false-positive where unrelated reverts get mistaken for the guard firing. * RandomBeacon.StorageLayout.test.ts Reads RandomBeacon's storageLayout from the compiler build-info and pins (a) _reentrancyStatus is a uint256 with initial value 1, (b) _relayEntrySubmissionGasOffset is initialised to 13_450, (c) a small set of security-critical storage labels (authorisation source, sortition pool, staking) are still present. Direct slot reads avoid the gas-accounting noise of a refund-vs-cost test while catching the exact regressions of interest. * RandomBeacon.Relay.test.ts (submitter-made-whole sanity) Adds a refund >= gasCost assertion under the "submitted before soft timeout" branch. The fragile pin lives in the StorageLayout test; this one only catches the "submitter is paying out of pocket" failure mode, which is robust to gas-accounting drift. * hardhat.config.ts Enables storageLayout in solc outputSelection while preserving the default ABI / bytecode / metadata / methodIdentifiers selection so typechain and hardhat-deploy continue to work. --- .../test/ReentrantBeaconConsumer.sol | 55 +++++++ solidity/random-beacon/hardhat.config.ts | 24 +++ .../test/RandomBeacon.Reentrancy.test.ts | 103 ++++++++++++ .../test/RandomBeacon.Relay.test.ts | 18 +++ .../test/RandomBeacon.StorageLayout.test.ts | 153 ++++++++++++++++++ 5 files changed, 353 insertions(+) create mode 100644 solidity/random-beacon/contracts/test/ReentrantBeaconConsumer.sol create mode 100644 solidity/random-beacon/test/RandomBeacon.Reentrancy.test.ts create mode 100644 solidity/random-beacon/test/RandomBeacon.StorageLayout.test.ts diff --git a/solidity/random-beacon/contracts/test/ReentrantBeaconConsumer.sol b/solidity/random-beacon/contracts/test/ReentrantBeaconConsumer.sol new file mode 100644 index 0000000000..1e95c06f68 --- /dev/null +++ b/solidity/random-beacon/contracts/test/ReentrantBeaconConsumer.sol @@ -0,0 +1,55 @@ +// SPDX-License-Identifier: GPL-3.0-only + +pragma solidity 0.8.17; + +import "../api/IRandomBeaconConsumer.sol"; +import "../RandomBeacon.sol"; + +// Malicious IRandomBeaconConsumer used in F-09 regression tests. +// When invoked via the callback path, attempts to re-enter +// RandomBeacon.submitRelayEntry(bytes).

Neither delta is reachable today: `block.Number` is always populated from `(*big.Int).String()` of an Ethereum block header, which is non-negative and well below `MaxInt32` for the next ~800 years. **No observable behavior change in practice.** | +| Runtime behavior — disk persistence | **Yes, forward-only** | `disk_persistence.go` tightens `EnsureDirectoryExists` from `os.ModePerm` (0o777) → `0o750`. Affects newly-created node data and keystore directories. **Existing deployed nodes keep their current 0o777 permissions on already-created directories.** Same-group access still permitted (backup, sidecar). "Other" excluded. | +| Test code | No | Mock interface satisfaction; format-string vet fixes. Test-only. | +| CI workflow (`securego/gosec@v2.24.7`) | No | CI-internal. Will surface more analyzer rules on future PRs. | +| Minimum Go toolchain | No change from #16 | Already at `go 1.24.0` from PR #16. | +| go-ethereum version | No change | Still v1.17.3. | + +## Deployment / redeployment + +| Component | Action required | +|---|---| +| Smart contracts | **None.** No contracts in this repo. | +| `keep-core` nodes (client / beacon) | **No redeploy required for this PR alone.** Library tag only. Redeploy happens when downstream PR (tlabs-xyz/keep-core-security#13 or its successor) bumps its `keep-common` dep to the new tag and that node release is cut. | +| Off-chain services / monitoring | **None.** | +| CI infrastructure | None. The gosec action bump is self-contained (action pulls its own Docker image with Go toolchain). | +| Existing node persistence directories | **No action required.** New permissions (0o750) apply only to directories created after the bump lands in a deployed node. Operators who want consistency on existing dirs can `chmod 0750 ` manually, but it's not required for correctness. | + +## Release safety + +Safe to tag `v1.7.1-tlabs.2` from this branch (after the planned `v1.7.1-tlabs.1` from #16 is cut). Caveats: + +1. **Library tag, not a deployment.** Runtime risk lives in the downstream consumer's adoption PR, not here. The two behavior deltas (block counter parser, dir perms) only take effect once a `keep-core` release consumes this version. +2. **Block counter behavior delta is theoretically observable but practically inert.** The "rejects negative inputs" and "accepts > MaxInt32" branches require malformed RPC responses or block numbers ~800 years in the future, neither of which is reachable. Worth one sentence in the changelog so operators know the parser changed, but no operator-facing action needed. +3. **Directory permission tightening is forward-only.** New keystore/work dirs created on fresh node deployments will be 0o750. Existing operators with custom UID/group setups for backup or sidecar access should verify their access pattern uses the same group as the node process. Worth a CHANGELOG note for operators. +4. **gosec action bump may surface new findings on future PRs.** v2.24.7 added ~10 new analyzers (G117 expanded, G118-G123, G408, G705, G707). This PR cleared the three findings present on current main, but future PRs touching code those analyzers cover may produce new flags.

All in-tree callers either nil-check the result or pass it to a receiver-nil-safe method (`Equals`, `Add` with nil guard, `SetCurve`). External consumers must update if they relied on panic semantics — but the explicit Threshold callers (keep-core, etc.) consume only the high-level keygen/signing APIs, not these primitives directly. + +## On-chain / protocol impact + +- **Contracts: zero.** No `.sol` files in this repo. Nothing to deploy. +- **Wire format:** PR #4 introduces no new field on the wire. It rejects values that were already provably malformed under the protocol spec. Honest peers running PR #2 (without PR #4) produce messages that pass PR #4's stricter `ValidateBasic`. +- **Wire compatibility regression to consider — base PR #2's notice, inherited:** + > "This is a protocol/wire compatibility break for proof transcripts. Proofs whose Fiat-Shamir challenges now use tagged hashing or session context will not verify across mixed old/new versions … Operators should roll this out as a coordinated protocol upgrade." + This statement applies to the combined release. PR #4 does **not** add to the break. +- **Operator-controlled requirement (inherited from PR #2):** All callers must invoke `Parameters.SetSessionNonce()` / `SetSessionNonceBytes()` before starting keygen, signing, or ECDSA resharing. The protocol now fails closed without it. PR #4 does not change this requirement. +- **CGGMP'21 paper vs. implementation:** PR #4's FactorProof W/V/Sigma DoS bounds are stricter than the CGGMP'21 paper specification and the BNB / LFDT-Lockness reference implementations (both bound only Z1, Z2). The added bounds reject pathologically oversized response scalars before modular exponentiation. Strictly more defensive than the reference protocol; cannot reduce interoperability with conformant implementations. + +## Consumer impact (keep-core / tBTC nodes) + +- **keep-core** vendors `tss-lib` via `go.mod`. Bumping the dependency past the PR #2 + PR #4 cut is a coordinated protocol upgrade across the operator set. This is governed by base PR #2's break, not by PR #4. +- **Caller-side breaking source change required by base PR #2:** any keep-core code that constructs `tss.Parameters` and then runs keygen/signing must call `SetSessionNonceBytes(...)` before round 1 starts. If the keep-core integration of PR #2 is already in flight (or merged), PR #4 piggybacks on it with zero additional caller changes. +- **No `mta.ErrRangeProofVerify` adoption required** in keep-core: the existing error-handling path (`tss.Error.Culprits()`) still surfaces the offending peer ID; the new sentinel just improves the wrapped message text. + +## Deployment recommendations + +- **Contracts: no action.** +- **Coordinators / services: no action specific to this PR.** Inherits from PR #2 the requirement to provide a unique `SessionNonce` per ceremony. +- **Operator nodes:** + - PR #4 cannot be released alone; it ships with PR #2. + - When PR #2 lands and the keep-core operator fleet upgrades to a version that vendors it, PR #4 is a free hardening that ships in the same protocol-cut release. No second coordinated rollout. + - Old nodes that do not upgrade past PR #2 will already be incompatible with new ones (per PR #2's wire-format break notice). PR #4 does not widen this gap. +- **Rollback:** PR #4 alone is cleanly revertible (additive defensive checks + one logic fix in a stacked branch). Reverting `round_9.go`'s `||` → `&&` re-opens the latent bug — do not do so without replacing it with an equivalent guard. + +## Risk + +**Low for PR #4 in isolation.** All operator-facing behavior changes either (a) fail closed against malformed peers without affecting honest ones (verified by enumerating the honest sampling ranges and the local safe-prime generator's invariants), or (b) replace a panic with a `nil` return (`ScalarMult`/`ScalarBaseMult`) for inputs that honest paths never produce. + +**Inherited from PR #2: medium.** Wire-format break, coordinated upgrade, new mandatory `SessionNonce` caller contract. Assess separately when PR #2 is gated for release. + +The one real bug-fix in PR #4 (`round_9.go`) closes an exploit that requires: +- A malicious party with a valid keygen share (insider). +- Their commitment-only message in round 7 binding to ≠ 4 secrets. +- A choice of 4 attacker-controlled values that satisfy the `U == T` integrity check. + +Cost to the attacker is free (no hash collision). Outcome is bypassing the round-9 cross-check that ties their per-party `bigVi`/`bigAi` contributions to honest behavior, which the protocol uses to detect provably-deviating signers. Severity: medium for honest-majority assumption; low if the deployment also relies on independent on-chain detection of misbehavior. + +## Tests added in this review pass + +Two commits added in the review session (`9e272cc`, `5e9e99e`): + +- `ecdsa/signing/round_9_test.go` — new file. `TestDecommitFour` with 4 subtests (4 secrets accepted, 3/6 rejected, mismatched commit rejected). Mutation-detectable: reverting `||` → `&&` fails `rejects_three_secrets` and `rejects_six_secrets`. +- `ecdsa/keygen/messages_test.go` & `ecdsa/resharing/messages_test.go` — added `BitLen == 2047` boundary assertions for both `PaillierN` and `NTilde`, pinning the just-below-2048 case alongside the existing `BitLen=1` and `BitLen=2049` cases. + +## CI + +- Workflows `Go-fmt` and `Go Test` run via `workflow_dispatch` (they only auto-trigger for PRs targeting `master`; this PR targets `integrate-bnb-hardening`). +- Manually triggered on the new HEAD `5e9e99e`: + - Go-fmt: ✅ success (run 26333181166) + - Go Test: in progress at time of writing (run 26333180587) +- Local validation passed: `go test ./ecdsa/signing` (13 tests, 10.7s), `go test ./ecdsa/keygen ./ecdsa/resharing` (36 tests, ~9 min). + +## Caveats + +- **PR title understates the scope.** Three of the most impactful changes (`round_9.go` `&&` → `||`, `ECPoint` nil-return contract, FactorProof W/V/Sigma DoS bounds) are Threshold-originated, not present in BNB upstream. The PR body's "Backport BNB v4 hardening" framing is technically a backport-plus, but reviewers should not assume each diff has a BNB precedent. +- **EdDSA paths are touched but not tested adversarially.** PR #4's shared-crypto changes (VSS, Schnorr, ECPoint) flow into the EdDSA keygen/signing/resharing rounds. Honest EdDSA flows are unaffected (curve-correct `ec.Params().N` usage throughout), but no negative-path tests pin the new guards in the EdDSA path.

Additionally, two shares with identical IDs (or IDs equal mod q) produced a zero Lagrange denominator → `ModInverse(0) == nil` → nil-deref in interpolation. The PR adds: + - Explicit `shares[0] == nil` check before threshold validation. + - Per-share nil-field validation in the dedup loop. + - Zero-ID-mod-q rejection (a zero share ID would encode the secret directly). + - Duplicate-ID-mod-q dedup using `map[string]struct{}`. + Honest callers (well-formed shares generated by `vss.Create`) observe no behavior difference; the new error paths are unreachable for any input that satisfies VSS's own invariants. + +2. **Nothing else.** All other touched files are docstring-only edits. No hash inputs, no domain separators, no message encodings, no field layouts changed. + +## Wire format / protocol impact + +- **Wire format: unchanged.** No proto edits, no struct field edits, no serialization edits. Every byte produced on the wire by ECDSA keygen and signing is identical pre- and post-PR. +- **Fiat-Shamir challenge derivation: unchanged.** `RejectionSample` was only annotated with documentation. The underlying call (`LiterallyJustMod`) is byte-identical. The PR's correction of the `RejectionSample` bias docstring (recommended fix to a math error in the new docstring's bound formula — see the multi-agent review) does not affect any computed challenge value. +- **SSID derivation: unchanged.** `getSSID` in both keygen and signing was only annotated; the hash input list (curve params, party IDs, `round.number`, `ssidNonce`) is byte-identical. +- **Paillier `FactorChallenge`: unchanged.** Both the tagged path (`e ∈ [0, 2^256)` via `SHA512_256i_TAGGED` + modular reduction) and legacy path (`e ∈ [-(2^256-1), 2^256)` via `HashToN(2q-1, …) - (q-1)`) are byte-identical; the PR only documents which absolute-value bounds in `FactorVerify` are present to accommodate the legacy signed encoding. +- **`SessionNonce` contract: unchanged.** Still fail-closed when not set, still requires ≥16 bytes via `SetSessionNonceBytes`. PR #6 only expands the docstring with the per-ceremony-uniqueness and high-entropy guidance that reviewers asked for; the runtime contract is identical. + +Two parties — one running pre-PR #6 (i.e. PR #5 HEAD) and one running post-PR #6 — will compute byte-identical SSIDs, byte-identical Fiat-Shamir challenges, byte-identical VSS commitments, and byte-identical wire messages, on every honest input. + +## On-chain / protocol impact + +- **Contracts: zero.** No `.sol` files in this repo. Nothing to deploy. +- **Wire format change in this PR: none.** PR #6 contributes nothing to the wire/transcript break described in PR #2's release notes. +- **Operator-controlled requirements (all inherited from PR #2):** `SetSessionNonce` / `SetSessionNonceBytes` must be called before keygen and signing.

No removals, no signature changes, no behavior change for honest callers. +- **`ReConstruct` callers downstream:** `ReConstruct` is invoked only inside `tss-lib`'s own tests (VSS tests + `ecdsa/keygen/local_party_test.go`). It is not on any keygen or signing wire path. If `keep-core-security` calls `ReConstruct` for share-backup or recovery flows, those callers will continue to receive valid secrets for honest inputs and will now receive a typed error (instead of a panic) for malformed inputs — a strict improvement. +- **Module-graph: unchanged.** No `go.mod` / `go.sum` deltas. `keep-core-security` re-vendoring this commit will see only the documentation and the VSS validation diff. +- **`SessionNonce` adoption requirement (inherited from PR #2):** unchanged by PR #6. The docstring expansion is informational — the same runtime guard at the same call sites with the same panic conditions. + +## Residual review-item resolution (documentation only) + +The multi-agent review of `c9e9c09` flagged a factual issue in the newly-added `RejectionSample` bias docstring: the stated bound `q / 2^eHash.BitLen()` was loose to the point that it could not support the docstring's own ~2^-128 conclusion for secp256k1, and the "q significantly smaller than 2^256 (e.g., q = 2^256)" example was internally inconsistent. + +**Resolved in `f973d1f`** (this PR's second commit). The paragraph now states the safe regime as a property of q ("close to 2^k from below") rather than via a loose formula or call-site enumeration, drops the unused curve25519 reference whose conclusion is correct but not derivable from the simple bound, and cross-references `HashToN` / `HashToNTagged` for the large-modulus regime that they were introduced to address. + +`f973d1f` is documentation-only — `RejectionSample`'s runtime behavior (`LiterallyJustMod` under the hood) is byte-for-byte unchanged. No computed Fiat-Shamir challenge moves. + +## Deployment recommendations + +- **Contracts: no action.** +- **Coordinators / services: no action specific to this PR.** Inherits from PR #2 the requirement to provide a unique `SessionNonce` per ceremony — unchanged. +- **Operator nodes:** + - PR #6 cannot be released alone; it ships stacked on PR #5 / PR #4 / PR #2. + - When the keep-core-security operator fleet upgrades to a version that vendors the combined stack, PR #6 contributes: (a) a defensive nil/dedup guard on `vss.Shares.ReConstruct` that converts a latent nil-deref into a typed error, and (b) clarifying documentation on `SessionNonce` usage, the BNB-RejectionSample modular-reduction choice, ECPoint mutation semantics, getSSID round-1 invariant, and `FactorChallenge` two-path encoding. + - **No second coordinated rollout is needed for PR #6**; it piggybacks on the PR #2 protocol-cut release. +- **Rollback:** PR #6 alone is cleanly revertible by re-vendoring the PR #5 HEAD SHA.

CI workflow gains a `free-disk-space` step (SHA-pinned to `jlumbroso/free-disk-space@54081f1`, v1.3.1) because the multi-arch image build exhausts the default ~14 GB on `ubuntu-latest`. + +Scope is tight: 3 files (`go.mod`, `go.sum`, `.github/workflows/client.yml`). **Zero application source changes.** + +## Breaking changes + +None at the operator / wire / consensus / contract surface. + +| Surface | Changed? | Notes | +|---|---|---| +| Wire protocol (libp2p `/keep/handshake/1.0.0`) | No | This PR doesn't touch libp2p, `pkg/net/*`, or the security protocol ID | +| Smart contracts (Solidity) | No | Zero contract files touched; deployed contracts unaffected | +| ABI bindings (`pkg/chain/ethereum/.../gen/contract/*.go`) | No | Generated code unchanged; existing bindings still compile against go-ethereum v1.17 | +| `ethclient` JSON-RPC traffic | No | RPC method set used (`HeaderByNumber`, `TransactionReceipt`, `SuggestGasPrice`, `SubscribeNewHead`, etc.) is API-stable across v1.13–v1.17 | +| Transaction encoding (legacy / dynamic-fee / access-list) | No | go-ethereum v1.14+ added blob-tx support (EIP-4844); legacy encodings are unchanged; keep-client does not emit blob txs | +| Signing (`crypto.Sign` / `crypto.Ecrecover`) | No | secp256k1; signature bytes deterministic across the range | +| Keystore format (V3 JSON) | No | Stable; existing operator keystores load unchanged | +| Configuration / flags / env vars | No | No CLI, config-file, or env-var changes | +| Persistent state / on-disk format | No | keep-core does **not** import `core/rawdb`, `ethdb`, `trie`, `node`, `rpc`, `eth/protocols`, or any go-ethereum storage package (verified by grep) | +| `go.mod` direct deps | Yes | `go-ethereum` 1.13.15 → 1.17.3; `keep-common` replace 1.7.1-tlabs.0 → 1.7.1-tlabs.1 | +| `go.mod` indirect deps (new) | Yes | `crate-crypto/go-eth-kzg`, `ethereum/c-kzg-4844/v2`, `emicklei/dot`, `ProjectZKM/Ziren/crates/go-runtime/zkvm_runtime` (forced by go-ethereum/crypto; not invoked from keep-core's call graph) | +| `go.mod` indirect deps (bumped) | Yes | `gnark-crypto` 0.12 → 0.18, `holiman/uint256` 1.2 → 1.3, `blst` 0.3.11 → 0.3.16, `fastssz` 0.1.2 → 0.1.4, `cobra` 1.5 → 1.8, etc. | +| CI workflow | Yes | New `free-disk-space` step at the start of `client-build-test-publish` (SHA-pinned) | + +## Behavioral changes (intended) + +- **CI runners** now have ~30 GB extra free space before the multi-arch build starts (removes Android / .NET / Haskell toolchains, all unused by keep-client). Without this, the v1.17 build OOM'd on disk. Pinned to commit SHA, not `@main`, since the step runs in a job that later authenticates to Docker Hub, AWS, and GHCR. +- **go-ethereum runtime behavior**: no semantic change to the methods/types keep-core consumes. The v1.13 → v1.17 range introduced blob transactions (EIP-4844), Verkle trie scaffolding, and Amsterdam-fork preparation in upstream — all are server-side concerns; the **client-side** API surface keep-core uses (`types.Transaction`, `bind.BoundContract`, `ethclient.Client`, `crypto.Sign`/`Ecrecover`, ABI binding helpers) is stable. + +## Network compatibility (mixed-version peer network) + +The keep-network is a long-lived P2P validator network. New keep-client binaries built from this PR will run alongside operator nodes still on `v2.5.2` (post-PR-#10) and earlier. + +- **libp2p / handshake**: untouched by this PR (PR #10 already handled the libp2p refresh, which was verified mixed-version safe). Custom security protocol ID `/keep/handshake/1.0.0` unchanged. +- **L1 RPC traffic**: keep-client talks JSON-RPC over HTTP/WebSocket to the operator's chosen Ethereum node (geth / erigon / nethermind). The RPC protocol is independent of the in-process `ethclient` Go API version. Compat with the L1 RPC endpoint is unchanged. +- **On-chain calls**: contract addresses, ABIs, function selectors all unchanged. Existing T / tBTC contracts continue to be called the same way. + +## Supply-chain notes + +- **`ProjectZKM/Ziren/crates/go-runtime/zkvm_runtime`** is a new transitive indirect dep (pseudo-versioned, Apache-2.0, MIPS zkVM runtime). `go mod why` confirms it's reachable via `go-ethereum/crypto` — i.e., it's a forced transitive from upstream. Not invoked directly from any keep-core source. Documented in the PR body for reviewer awareness. Org is legitimate (117 stars, active, Apache-2.0); not a typo-squat. Cannot be severed without forking go-ethereum. +- **`ethereum/c-kzg-4844 v0.4.0`** dropped; replaced by **`ethereum/c-kzg-4844/v2 v2.1.6`** + **`crate-crypto/go-eth-kzg v1.5.0`** (KZG commitments for blob tx support — unused at runtime by keep-client but present in the binary). +- **Socket Security** scan on the PR: go-ethereum vulnerability score +31, supply-chain score +1; no new alerts. + +## Vulnerabilities addressed + +| CVE | Severity | CVSS | Fixed in go-ethereum | +|---|---|---|---| +| CVE-2026-22862 | High | 7.5 | v1.16.8 | +| CVE-2026-22868 | High | 7.5 | v1.16.8 | +| CVE-2026-26313 | High | 7.5 | v1.17.0 | +| CVE-2026-26314 | High | 7.5 | v1.16.9 | +| CVE-2026-26315 | High | 7.5 | v1.16.9 | + +All 5 cleared by pinning to v1.17.3. + +## Is it safe to release / redeploy? + +**Yes, with the standard rollout flow.** No contract changes, no state migration, no operator-visible config changes, no wire-protocol break, no source-level behavior change. + +**Required redeploys:** + +- **keep-client nodes (operators)**: yes — rebuild and roll out the new image to pick up the patched go-ethereum dependency. This is a binary-level refresh; no operator action beyond pulling the new image and restarting. +- **Smart contracts**: no — zero contract code touched. +- **Off-chain services (relays, observers, signers)**: no — unless they share the `keep-client` image; in that case, same as operator redeploy. +- **Operator keystores / wallet files**: no — V3 keystore format is stable across the go-ethereum range. +- **L1 Ethereum node operators run alongside (geth / erigon / nethermind)**: no — independent. + +**Suggested rollout:** + +1. Wait for PR #13 CI (`client-build-test-publish`, `client-scan`, `client-vet`, `client-lint`) to go green on the rebased tip. +2. Run Sysdig rescan against the new image; verify all 5 go-ethereum CVEs from this PR plus the libp2p / Go-runtime CVEs from PR #10 are clear. +3. Deploy to staging; confirm the new client connects to mainnet RPC and exchanges traffic with at least one pre-bump peer. Wire protocol is unchanged so this should be a no-op verification. +4. Smoke-test a `tbtc` end-to-end interaction in staging (deposit / redemption flow); this covers the `ethclient`, `bind`, and `crypto.Sign` paths. +5. Roll to mainnet operators one node at a time; watch peer-count, RPC-error rate, and on-chain tx success metrics. +6. Hold one pre-bump node in the network post-rollout for several days to confirm sustained interop. + +## Open / deferred items + +- **PR-test-plan items 2 and 3** (staging spot-check + Sysdig rescan) remain open at PR-body level. CI item 1 is currently UNSTABLE (re-running post-rebase) — confirm green before merge. +- **Forked `keep-common`** (`threshold-network/keep-common v1.7.1-tlabs.1`) is now a hard prerequisite for go-ethereum 1.16+ in this codebase. Each future go-ethereum bump that crosses an abigen/`go:linkname` change will require a corresponding `tlabs.N` tag. Not a release blocker, but worth tracking long-term (either upstream or accept as a permanent fork). +- **Ziren transitive** stays in the dependency closure as long as go-ethereum keeps it in `crypto`. Re-evaluate at the next go-ethereum bump. + +## Reviewer notes / risk classification + +- **Code risk**: very low — zero application source changes; only `go.mod` / `go.sum` movement and one CI step. +- **Build risk**: low — CI re-running on the rebased tip; main's existing Docker pins (`golang:1.25.5-alpine3.21`, `golang:1.25.10-bookworm`) inherited from PR #10 carry over unchanged. +- **Network risk**: very low — no libp2p, no protocol ID, no RPC contract changed. +- **Consensus / contract risk**: none — no Solidity, no on-chain interaction surface changed. +- **Supply-chain risk**: low-medium — one new untagged transitive (Ziren) forced by upstream; documented; not in keep-core's call graph. Socket scan net-positive. +- **Operational risk for redeploy**: low — drop-in replacement; no state migration; safe rolling deploy. + +## Rebase note (2026-05-23) + +PR #10 squash-merged into main at 2026-05-23T10:59:41Z, which auto-retargeted PR #13 from `fix/sysdig-tbtc-2.5.2-cves` to `main` and deleted the old base branch. The branch was then rebased onto `origin/main` via `git rebase --onto origin/main c6df34aae HEAD`, dropping the 4 pre-squash commits that overlapped with PR #10's content (`bf5307ff4`, `81b42c3d8`, `e2a8c74cb`, `c6df34aae`) and preserving only the 4 PR-13-specific commits. No manual conflict resolution was required. Verified clean afterwards: `go build ./...` clean, `go vet ./...` shows only the two pre-existing warnings in `pkg/tbtcpg/internal/test/marshaling.go` and `pkg/tecdsa/signing/protocol.go` (unchanged by this PR).

Wire-breaking changes in the Go client + +Both changes are deterministic and identical-across-nodes; running a heterogeneous fleet -- some old, some new -- will produce inter-node protocol failures, **not** local errors. A staged rollout is unsafe. + +### F-02 -- `G1HashToPoint` output changes for the same input + +* **File:** `pkg/altbn128/altbn128.go:120-162` +* **Before:** try-and-increment (`x = sha256(m)`; while not on curve, `x += 1`). +* **After:** counter-based hash-and-try (`sha256(m || ctr)`; `ctr` in `[0, 63]`, return first valid point). +* **Wire impact:** + * BLS `Sign()` / `Verify()` -- `pkg/bls/bls.go:51,63`. Old and new nodes will not agree on `H(message)`, so the recovered relay entry signature will fail on-chain BLS verification at `Relay.sol:150-157`. + * GJKR DKG Pedersen generator H -- `pkg/beacon/gjkr/protocol_parameters.go:24`. Old and new nodes will not agree on the commitment generator; commitments will not verify and the DKG will abort. +* **Note from the source:** the in-file comment at `altbn128.go:140-142` explicitly states "Deployment requires a coordinated network upgrade." +* **Residual concern (not new in this PR):** the counter-based loop panics if all 64 attempts fail. Probability per input is `(1/2)^64 ≈ 5e-20`. The panic is identical across nodes by construction (deterministic), so any reachable trigger is a chain-halt class event. All known production callers feed public inputs into this primitive (see F-02.md call-site table), so the panic cannot be deliberately triggered by an attacker. Future RFC 9380 SWU migration (tracked in [issue #4](https://github.com/tlabs-xyz/keep-core-security/issues/4)) is single-pass and eliminates this class. + +### F-03 -- ECDH session-key derivation switches from `sha256` to HKDF-SHA256 with a domain-separation `info` label + +* **File:** `pkg/crypto/ephemeral/symmetric_key.go:24-40` +* **Before:** `key = sha256(btcec.GenerateSharedSecret(priv, pub))` -- no salt, no info, no domain separation across protocols or peer pairs. +* **After:** `key = HKDF-SHA256(ikm = sharedSecret, salt = nil, info = || min(idA,idB) || max(idA,idB))`. Where `` is one of: + * `"gjkr"` (4 callers in `pkg/beacon/gjkr/protocol.go`) + * `"tecdsa-dkg"` (1 caller in `pkg/tecdsa/dkg/protocol.go`) + * `"tecdsa-signing"` (1 caller in `pkg/tecdsa/signing/protocol.go`, also includes `sessionID`) +* **Wire impact:** For the same ECDH shared secret, the old construction and the new construction produce different 32-byte symmetric keys. Old and new nodes will fail to decrypt each other's GJKR and tECDSA peer-to-peer share messages. Both the beacon DKG and the tECDSA DKG/signing protocols will abort on the first encrypted-share exchange. +* **Invariant:** the `info` encoders serialize each `MemberIndex` as a single byte (`byte(id)`). This relies on `group.MemberIndex` being a `uint8`. The dependency is now pinned by a compile-time assertion in `pkg/protocol/group/group.go` and a runtime check in `pkg/protocol/group/member_index_test.go` -- any future widening of `MemberIndex` would be caught at build time. If the type is ever widened, the `*EcdhInfo` encoders must move to a width-independent encoding (e.g. `binary.BigEndian.PutUint16`) in the same coordinated upgrade. +* **No persistence:** ECDH keys are ephemeral, regenerated per session; no migration of stored data. + +### Non-breaking fixes that ship in the same Go-binary cutover + +These ride along with the F-02/F-03 binary upgrade. They're not wire-breaking, but they activate at the same moment, so include them in the cutover release notes: + +* **F-13** -- tBTC event deduplicator TOCTOU fix (`pkg/tbtc/deduplicator.go`). Removes a race window where the same Ethereum event could be processed twice. Behaviour change: no observable difference under normal load; under high-concurrency event delivery, duplicate notifications now collapse to one. +* **F-15** -- `sqrtGfP2` exponent cross-check (`pkg/altbn128/altbn128_test.go`). Adds a test asserting the hardcoded exponent equals `(p^2 + 15) / 32`. Source code unchanged; this is a regression guard only. No runtime impact. + +### Combined coordination requirement + +`SECURITY-BREAKING-CHANGES.md` already documents the cutover checklist. Both changes activate at the binary level (no chain flag or block height read); the operative cutover is the operator software upgrade itself. + +Minimum operational steps: + +1. Agree a cutover block height with all operators. +2. Stage and dry-run on a testnet with the full fleet. +3. Coordinate simultaneous binary swap at the cutover height. Rolling upgrades will cause BLS submissions to revert and DKGs to fail. +4. Post-cutover monitoring: alert on BLS-verification reverts (`Relay.sol`), on DKG failure rates, and on peer-to-peer share decryption errors. + +## 2. On-chain contract changes + +### `RandomBeacon.sol` (F-09 fix) + +* **Storage layout change:** adds `uint256 private _reentrancyStatus`. Initialised to `1` in the constructor. +* **Logic change:** `submitRelayEntry(bytes)` (line 1054) and `submitRelayEntry(bytes, uint32[])` (line 1083) now carry an inline `nonReentrant` modifier; OZ `ReentrancyGuard` is **not** inherited (EIP-170 bytecode budget pressure). +* **Constant change:** `_relayEntrySubmissionGasOffset` constructor default bumped from `11_250` to `13_450` (+2,200 gas) so the relay-entry submitter is fully reimbursed for the additional SSTORE on the modifier's exit path. Tests at `solidity/random-beacon/test/fixtures/index.ts` updated to match. +* **Upgradability:** `RandomBeacon` is deployed via `hardhat-deploy`'s plain `deployments.deploy(...)` (`solidity/random-beacon/deploy/04_deploy_random_beacon.ts:34-53`). No proxy. **The contract is not upgradeable.** Existing mainnet deployment (`0x5499f54b4A1CB4816eefCf78962040461be3D80b`) cannot receive the F-09 fix in-place. + + Deploying the fix on mainnet therefore requires: + 1. Fresh `RandomBeacon` deployment at a new address. + 2. `transferOwnership` of `BeaconSortitionPool` to the new address. + 3. Re-authorisation of the new `RandomBeacon` in `TokenStaking`. + 4. Re-authorisation of the new `RandomBeacon` in `ReimbursementPool`. + 5. Deploy a new `RandomBeaconGovernance` pointing at the new address (`07_deploy_random_beacon_governance.ts`). + 6. Migrate active groups, in-flight relay entries, and authorisations -- or accept that running groups must expire / be rebuilt on the new instance. + 7. Update every on-chain `IRandomBeaconConsumer` to point at the new address (notably `WalletRegistry` for tBTC). + + **This is a major redeployment event.** Treat it the same way the original RandomBeacon launch was treated, including a multi-week operator coordination window. + + **Operational consequence -- the F-09 security benefit lags the Go-binary release.** Between the Go-binary cutover (§1) and the RandomBeacon redeployment, F-09 remains live on mainnet. The Go binary cannot install the on-chain `nonReentrant` modifier; only a new contract deployment can. If the redeployment is deferred indefinitely, the pentest finding is "remediated" in the source tree while the on-chain attack surface is unchanged. Track the redeploy as a deliverable, not a follow-up. + +* **Gas-offset interaction with existing deployments:** the storage slot `_relayEntrySubmissionGasOffset` is governable (`RandomBeacon.sol:666`). An existing deployment could in principle have its gas offset bumped via governance, but without the modifier the bump over-reimburses callers. Don't apply the gas-offset bump independently of the modifier. + +### `solidity-v1` (legacy contracts) + +The PR carries source updates to `KeepRandomBeaconOperator.sol`, `KeepRandomBeaconServiceImplV1.sol`, plus a new `RelayEntryServiceStub.sol` test stub. Per F-14, the v1 contracts are deprecated, **not upgradeable**, and the deployed mainnet code is immutable. Source updates here are historical / advisory only and have no on-chain effect. No deployment action needed. + +### `solidity-v1/yarn.lock` and `solidity/random-beacon/yarn.lock` + +`scryptsy@^2.1.0` removed from the random-beacon yarn lock -- transitive dep cleanup, no on-chain effect. + +## 3. Operator-facing config defaults + +* **`cmd/flags.go:257`, `cmd/flags_test.go`, `configs/config.toml.SAMPLE`:** `clientInfo.port` default flipped from `9601` to `0`. `0` disables the metrics/diagnostics HTTP server entirely. This change came in via the merge of `main` (commit `918009d78` -- "align operator-facing samples with diagnostics opt-in default") and is part of the same release. +* **Operator-facing impact:** any operator who was relying on the historical default (i.e. did not explicitly set `clientInfo.port` in their config) will **silently lose** their metrics endpoint after upgrade. Prometheus scrape jobs targeting `:9601` will start failing. +* **Operator runbook update required:** + * Audit operator configs for an explicit `[clientInfo] / Port = ...` entry. + * If absent and metrics are wanted: add `Port = 9601` (or whichever port the scrape job expects) before upgrade. + * If present: no action. +* Per F-12 guidance, operators should also firewall this port to their scraper's IP range -- it exposes peer topology and operator chain address. + +## 4. Library / dependency-level changes + +### libp2p Keep authentication handshake -- 15s deadline (`pkg/net/libp2p/transport.go`) + +* Adds a 15s absolute deadline to the Keep authentication handshake that runs **after** the TLS upgrade. +* **Why:** without it, a peer that completes TLS and then stalls parks the connection inside a blocking `proto-delim` read, occupying a libp2p resource-manager transient inbound slot until the daemon restarts. This is a DoS pressure-relief, not a wire-protocol change. +* **Protocol compatibility:** old and new clients still complete the same handshake; only the local timeout differs. Slow-but-honest peers within 15s are unaffected. **Not a wire-breaking change.** + +## 5. Persistence and on-disk formats + +No protobuf, serialization-format, or key-storage layout changes. Operators upgrading the binary keep using their existing work directory, keystore, and pre-parameter cache. + +## 6. CI workflow changes (non-shipping) + +`.github/workflows/contracts-{ecdsa,random-beacon}.yml`: the transient `security/whitebox-pentesting-materials` branch entry was removed from `pull_request.branches` before merge -- a CI nudge for the predecessor PR that is no longer needed on `main`. + +`.github/workflows/client.yml`, `contracts-ecdsa-docs.yml`, `contracts-random-beacon-docs.yml`: `permissions:` key order changed during the merge to align with `main` (`contents: read` before `pull-requests: read`). Pure cosmetic. + +## 7. Release / redeploy decision matrix + +| Component | Action | +|-----------|--------| +| `keep-core` Go binary on all operator nodes | **Coordinated upgrade required.** Cutover height agreed; rolling upgrade is unsafe (F-02 + F-03). | +| `RandomBeacon` mainnet contract | **Redeploy at new address.** Non-proxy. Multi-week migration window. Update every `IRandomBeaconConsumer` (notably `WalletRegistry`/tBTC). Or defer the F-09 redeployment to a later batch if the practical exploitability of the unguarded callback is below the redeployment risk. | +| `WalletRegistry`/tBTC ECDSA contracts | No code change in this PR. F-07 explicitly mitigated by design; F-08 accepted post-TIP-092. No on-chain change required. | +| `solidity-v1` contracts | Immutable; no action. | +| Operator config | Audit `clientInfo.port`; add explicit value if metrics scrape is in use. | +| Prometheus / monitoring | Confirm scrape targets remain reachable post-upgrade given the new disabled-by-default behaviour. | + +## 8. Rollback considerations + +* **Go binary rollback:** possible **only before** the cutover height passes. Once new-format BLS / HKDF traffic enters the network, mixed-version fleets will fail. Have a tested rollback binary path before cutover. +* **`RandomBeacon` redeploy rollback:** the new deployment is at a new address. Rolling back means re-pointing consumers at the old address. Practical only if no production traffic has hit the new instance. +* **Operator config rollback:** trivial -- revert config and restart. + +## 9. Open follow-ups (not blocking this release) + +* RFC 9380 SWU hash-to-curve migration -- [issue #4](https://github.com/tlabs-xyz/keep-core-security/issues/4). Eliminates the residual F-02 panic class. Optional; no security impact. +* `WalletRegistry` non-atomic upgrade discipline -- [issue #6](https://github.com/tlabs-xyz/keep-core-security/issues/6). Operational runbook only. +* `keep-common` password-to-key KDF (Argon2id / scrypt / PBKDF2 instead of bare `sha256`). External library, separate release. + +## 11.

Bottom line + +* **Safe to merge to `main` in this repository?** Yes -- the PR's content is correct, tested, and reviewed. +* **Safe to release the binary to mainnet operators without coordination?** **No.** F-02 + F-03 require a synchronized network-wide cutover. +* **Safe to redeploy `RandomBeacon` without migrating consumers?** **No.** Plan the redeploy as a multi-step on-chain event with consumer updates. +* **Recommended sequencing if both deployments proceed:** + 1. Testnet cutover with the full fleet to validate F-02/F-03 wire compatibility. + 2. Mainnet binary cutover (Go client) at an agreed block height. Treat the operator config audit (`clientInfo.port`) as a prerequisite. + 3. `RandomBeacon` redeployment as a separate, later operation -- treated as a fresh contract launch.

Application-level session ID format change + +Independent of the tss-lib wire change, keep-core's own session ID **string format** changed in this PR. Session IDs are serialized as the `SessionID` field of every protobuf message in `pkg/tecdsa/dkg/marshaling.go` and `pkg/tecdsa/signing/marshaling.go`, and they are used as a ceremony match key in `pkg/tecdsa/{dkg,signing}/states.go` (e.g. `member.sessionID == protocolMessage.SessionID()`). A peer whose session ID string does not match the message's session ID drops the message. + +| Helper | Pre (`main`) | Post (this PR) | +|---|---|---| +| `dkgAttemptSessionID(seed, n)` | `"-"` | `"dkg--<016x n>"` | +| `signingAttemptSessionID(message, startBlock, n)` | `"-"` | `"signing--<016x startBlock>-<016x n>"` | + +Why this changed: + +- Adds a typed prefix and fixes width so the value clears tss-lib's new 16-byte minimum for `SetSessionNonceBytes`. +- Adds `attemptStartBlock` for signing so repeated same-digest ceremonies do not reuse the GG20 SSID across retries (forensic and security follow-up to the BNB GG20 SSID-uniqueness hardening). +- Computed once per attempt in the retry loop (`signing_loop.go`, `dkg_loop.go`) and threaded through `signingAttemptParams.sessionID` / `dkgAttemptParams.sessionID` so the announcer and the protocol cannot drift. + +**Operator-visibility:** session IDs appear in logs (`zap.String("signedMessage", ...)` etc.). Any external dashboard or alerting rule that pins the old `-` shape will see a string-prefix change. Grep against this repo found no operator-facing consumers; verify against any internal observability tooling before rollout. + +## 3. Required `fullBytesLen` argument + +`pkg/tecdsa/signing/member.go:147-156` now passes `fullBytesLen := (tecdsa.Curve.Params().N.BitLen() + 7) / 8` (32 bytes for secp256k1) into `signing.NewLocalParty`. Per the upstream report: + +> ECDSA/EdDSA signing constructors still accept `fullBytesLen` as a variadic argument for source compatibility, but exactly one positive value is required at runtime so all signers agree on message byte width before the protocol starts. + +If a pre-hardening peer ever signed with messages that started with leading zero bytes, its signatures could be off-by-one bytes shorter than what the chain expects; the fix is to require agreement on `fullBytesLen` up-front. Post-hardening signers all agree on 32 bytes for secp256k1. Pre-hardening signers do not send this and the post-hardening peer will refuse to proceed. + +## 4. Surfaces explicitly NOT changed + +- **Random Beacon stack** (`pkg/beacon/`): does not depend on `tss-lib`; uses keep-core's own GJKR DKG and BLS. Untouched. +- **Smart contracts**: zero `*.sol` files touched (verified by `git diff main...HEAD -- 'solidity/**' 'contracts/**'` returning empty). No proxy upgrade, no new deployment, no storage-slot or constant change. +- **On-disk persistence**: post-DKG key share files remain readable. There is no new field, no marshaling format change to the *stored* key share. Only **in-flight protocol message bytes** change. +- **CLI / config / env**: no flag, env, or config-file change. Operators do not need to edit `keep-client.toml` or similar. +- **libp2p / Keep auth handshake**: no change. Wire compatibility breaks at the *protocol-content* layer (tss-lib message bytes) but not at the transport / handshake layer. + +## 5. Required redeploys + +- **tBTC operator nodes (`keep-client`)**: **yes — mandatory, coordinated**. Every operator that is a member of a tBTC wallet's signing group must run a post-hardening binary before the next DKG or signing ceremony for that wallet, or the ceremony fails closed (timeouts and proof-verification rejections; see §1 table). No contract redeployment; no migration; just the binary replacement and a normal node restart per node. +- **Random Beacon operator nodes**: redeploy is **safe** (no change to beacon code) but **not required for correctness** — the Random Beacon path is untouched by this PR. In practice keep-client is one binary serving both, so the bundled redeploy ships both at once. +- **Smart contracts (tBTC bridge, RandomBeacon, WalletRegistry, etc.)**: **no** — zero Solidity touched. +- **Off-chain services (relays, observers, monitoring)**: **no**, unless they share the keep-client binary; observability services that only watch the chain are unaffected. +- **Release artifacts (Docker images, `output-bins` tarballs)**: standard rebuild and publish. + +## 6. Recommended rollout + +Because the wire break is **proof-content**, not handshake-content, a mixed-version network will not see drop-on-connect failures; it will see DKG attempts that announce successfully but then fail proof verification mid-protocol, retry, and eventually time out. That is harder to debug than an immediate disconnect, so the rollout should be aggressive about ensuring no holdouts. + +1. **Build and tag a new client release** (`vX.Y.Z+1`) that pins `tss-lib` at `ae7075f3409e` (this PR). Publish operator-facing release notes that name the wire break and require a coordinated upgrade. +2. **Staging / devnet dry-run**: stand up a full signing group on the new binary; perform end-to-end DKG and signing ceremonies; confirm the GG20 SSID-uniqueness assertion (retries of the same digest no longer share an SSID); confirm `SetSessionNonceBytes` is called on every code path that constructs a `tss.LocalParty`. Confirm timing behavior: the PR body notes one combined pre-final local run hit DKG outgoing-message timeouts under load — verify staging signing-group block budgets are still comfortable on the new code. +3. **Communicate a hard cutover window** to all tBTC operators. Unlike a wire-compatible rolling restart, this requires every operator who participates in a wallet's signing group to be on the new client **before** the next DKG attempt for that wallet. There is no graceful degradation. Coordinate via the existing operator channel and have on-call ready for the cutover window. +4. **Roll mainnet** at the cutover window. The recommended order: + - First, operators that are NOT in any current wallet's signing group (low blast radius). + - Then operators currently in signing groups, coordinated so that each wallet's group either has 100% old or 100% new for any in-flight signing — never mixed. +5. **Post-rollout monitoring**: watch DKG and signing attempt counters per wallet; any wallet that retries DKG > 1 attempt or signing > 2 attempts in the first hour post-rollout should be inspected. Persistent retry storms indicate at least one holdout operator on the old binary. +6. **Hold the old binary off mainnet** — do not allow re-introduction of pre-hardening clients into the signing groups, because they will deterministically break new ceremonies. + +## 7. Reviewer / risk classification + +- **Code risk**: medium — the keep-core delta is small (15 files, +239/-31, dominated by tests). The dominant risk is in the upstream tss-lib delta, which is separately reviewed per the PR body links (`threshold-network/tss-lib#2`, integration notes in `BNB_HARDENING_INTEGRATION.md`). +- **Wire risk**: **high (coordinated cutover required)** — see §1 and §6. +- **Consensus / contract risk**: none — zero contract changes; the post-DKG public keys produced by previously-completed ceremonies remain valid and signable (the wallets themselves are not invalidated; only future DKG / signing protocol *runs* are wire-incompatible with old peers). +- **State migration risk**: none — no on-disk format change. +- **Operability risk**: medium — wire break is proof-content rather than handshake, so a partial rollout fails opaquely (timeouts + proof rejections), not loudly (disconnect). Mitigation: §6 step 3 (hard cutover window) and step 5 (active monitoring). +- **Security posture**: this PR is itself a security hardening. Pre-hardening, tss-lib had two ceremonies with otherwise-identical inputs deriving the same SSID (zero fallback for keygen / resharing, `SHA512_256(messageBytes)` fallback for signing), breaking the session-binding the proofs rely on. Post-hardening, that fallback is removed and SSID derivation is forced from a per-ceremony nonce. The rollout cost is finite; the risk of *not* rolling is an ongoing transcript-splicing exposure surface. + +## 8. Open items / follow-ups + +- **External observability rule audit**: confirm no dashboard, alerting rule, or log-scraper pins the old session-ID string format (`-`). Grep within this repo found no consumers; out-of-tree observability tooling should be checked separately. (Severity: cosmetic / operability.) +- **Socket security alerts on the PR (`babel-traverse`, `cipher-base`, `elliptic`, `es5-ext`)**: all are npm dev-tooling vulnerabilities not introduced by this PR (it touches no `package.json` or lockfile). Out of scope; tracked at the JS-tooling layer. +- **CodeRabbit auto-review**: paused itself on this branch ("under active development"). Re-trigger before merge if a fresh AI pass is desired. +- **Constant-time follow-up**: upstream PR `#328` (broad constant-time framework) was intentionally **skipped** by the hardening pin per the upstream report; it adds dependency and is default-disabled upstream. Tracked as a separate future security project; not blocking this release. +- **Test load sensitivity**: PR body notes one combined pre-final local run hit DKG outgoing-message timeouts under load. Suggest re-running `go test -count=3 ./pkg/tecdsa/dkg ./pkg/tecdsa/signing ./pkg/tbtc` on a CI agent with realistic CPU contention to confirm no flaky-timeout regression. +- **Resharing**: tss-lib resharing is hardened (SSID broadcast, new committee rejects old-committee broadcasts), but keep-core's tBTC stack does not currently invoke `Resharing`. If a future PR adds it, the integration must call `SetSessionNonceBytes` before `NewLocalParty` for the resharing parameters — same pattern as DKG and signing in this PR.

The release completion command chains on `go vet ./...`, so this unblocks the whole Go race + Solidity test run. Behavior is unchanged (signing tests pass). - pkg/tbtc: coordination_byzantine_test.go uses mustUnmarshalPublicKey(t, ...) to match main's #4167 two-value unmarshalPublicKey signature (merge follow-up). - .gitignore: drop the re-added `build/` entry (regressed edc434249). - RandomBeacon.Relay.test.ts: measured both overloads under a pinned hardfork. The single shared _relayEntrySubmissionGasOffset is tuned for the heavier bytes,uint32[] overload (uint32[64] intrinsic calldata), so bytes-only is structurally over-reimbursed (+9,563 gas at 13,450, +7,363 at 11,250) and cannot under-reimburse at the pre-fix offset. Replaced the tautological bytes-only control with a meaningful "already fully reimbursed at 11,250" assertion + a documented 10,000-gas over-reimbursement ceiling. hardhat.config pins hardfork "london" (gas-identical to the arrowGlacier default) to match the solc EVM target and make gas-refund measurements reproducible. - SECURITY-BREAKING-CHANGES.md: BC-10 now states RandomBeacon is directly deployed (not proxied) and activates only via a new deployment + address cutover, with a BC-10 note replacing the incorrect "proxy-safe"/"beacon proxy upgrade" wording. - cmd/maintainer_metrics_test.go: the enabled-port test now wires spv.SetMetricsRecorder and scrapes /metrics, asserting the three performance_redemption_proof_* series are exposed at zero. - header_cache_test.go: TestProveTransactionsSharesHeaderCacheAcrossProofTypes drives sm.proveTransactions once per simulated proof type with one shared cache (the maintainSpv structure), asserting each height is fetched once across proof types.

Fleet collector (8.4.2) hardening: - Reject a nonpositive CollectionInterval at construction (NewTicker panic). - Require a nonzero cutover block C before certifying readiness complete. - Verify eth_chainId matches the configured chain before trusting the block height; refactor RPC into a shared parameter-less helper. - Reject future-dated attestations and zero/future sighting timestamps. - Reconcile instances that disappeared from inventory as offline/blocking so removal never silently resolves central state (rules 2 and 6). - Expose inventory counts and per-instance reconciliation detail (class/reason/observed-vs-expected/quarantine) in the snapshot; report a real reporter count distinct from the instance count in the unresolved log. - Guarantee an incomplete readiness always raises a watched gauge so the CutoverRosterIncomplete alert fires. Add negative tests for each. Part B security records: drop false claims that this scoped build exposes compiled epoch/active-mode client-info signals (Part A's gate is out of scope); keep only exact-revision + stranded-peer evidence. Smoke harness: bounded probe retries (fix listener race); align README/compose network wording with the runnable private-bridge topology. --- CHANGELOG.md | 2 +- SECURITY-BREAKING-CHANGES.md | 6 +- cmd/cutover-roster/main.go | 95 ++++++-- cmd/cutover-roster/main_test.go | 27 +++ .../tlabs-xyz/keep-core-security/2.md | 2 +- pkg/monitoring/cutoverroster/collector.go | 201 ++++++++++++++--- .../collector_disappearance_test.go | 213 ++++++++++++++++++ pkg/monitoring/cutoverroster/types.go | 53 ++++- pkg/tbtc/node.go | 18 +- pkg/tbtc/node_test.go | 107 +++++++++ pkg/tbtc/tbtc.go | 27 ++- scripts/release/pr4109/README.md | 13 +- .../release/pr4109/clientinfo-port-smoke.sh | 25 +- scripts/release/pr4109/compose.yaml | 6 + security/findings/F-12.md | 8 +- security/threat-model.md | 6 +- 16 files changed, 728 insertions(+), 81 deletions(-) create mode 100644 pkg/monitoring/cutoverroster/collector_disappearance_test.go diff --git a/CHANGELOG.md b/CHANGELOG.md index 0458ce51d0..aacebcd0c5 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -64,7 +64,7 @@ The following changes are included in this PR for convenience but are **not** pa - `altbn128.G1HashToPoint` reimplemented from try-and-increment to a bounded counter-based `SHA-256(m || ctr)` (max 64 attempts); it produces a different G1 point for the same input (consensus-incompatible) and now panics if no valid point is found within the bound (#2) - `RandomBeacon` relay-entry gas offset `_relayEntrySubmissionGasOffset` raised from 11250 to 13450 to account for the reentrancy-guard SSTOREs (mirrored in the test fixture) (#2) - Enabled `storageLayout` output selection in the random-beacon Hardhat config, removed `scryptsy` from `yarn.lock`, and added `.envrc*`, `strix_runs/`, and `.claude/` to `.gitignore` (#2) -- **Operator action (temporary compatibility):** the `clientInfo.port` default is retained at `9601` for this coordinated security release so the client-info HTTP server (`/metrics` and `/diagnostics`) stays reachable through the cutover — the primary evidence channel for revision/epoch/mode and stranded-peer state must not go dark during deployment.

Part A stays undone and Part B is unchanged. - Node-local roster (8.4.1): ObserveLegacy now stamps a sighting with a synchronously read chain height instead of the height cached by the 30-second sweep loop, so a straggler observed the instant the chain reaches C is not stamped below C and discarded centrally as pre-cutover. A transient clock error falls back to the last known height rather than dropping the evidence. Adds C-boundary and clock-error tests. - Roster lifecycle: tbtc.Initialize closes/joins the roster's sweep loop on any post-construction init error (via a named-return guard), so a failed startup that leaves the parent ctx alive cannot leak the loop. - Fleet collector (8.4.2): reject a report that does not self-identify (empty instance ID or operator address), matching the reporter's documented contract that missing identity is rejected, not fabricated from inventory. Adds a negative test. - Adds a whole-operator-disappearance test proving the fail-closed property: a blocking operator that wholly vanishes from the inventory stays blocking while a still-present operator resolves independently.

It reproduces the exact error-path order (close stop, then close directly) and asserts Close is invoked twice yet takes effect once. Retitle the existing overlap test's comment to reflect that it covers the select's wake-up paths, not the double invocation. Passes under -race.

P0 — production discovery/identity is now authoritative, not optional (finding 1): - Completeness now REQUIRES service-discovery reconciliation and on-chain identity verification (CollectorConfig.RequireServiceDiscovery / RequireIdentityVerification, set true by the command). A missing feed blocks readiness instead of degrading to trusting inventory; the command warns that readiness cannot be certified. (isComplete, main.go) - Service discovery is keyed by network ID (per-instance) not operator-only, so multiple instances of one operator resolve to distinct discovered targets (ServiceDiscovery.byNetworkID, MetricsURLForInstance, InventoryInstance.NetworkID, applyDiscoveredTargets). - The metrics adapter validates the responding node's self-attested identity (diagnostics chain_address + network_id) instead of copying InstanceID/ OperatorAddress from inventory; a mismatch is rejected (reportadapter.go). P0 — reporter revision is durable across collector restart (net-new 1): - ReporterRevision now derives from the attestation timestamp (UnixNano) rather than a process-local counter that reset on restart and sat below the persisted high-water mark. Added TestCollector_ReportsAcceptedImmediatelyAfterRestart and TestMetricsReportSource_ReporterRevisionSurvivesRestart. P1 — remaining evidence gaps (finding 3): - StakingProvider must be a canonical, non-zero address; expected image digest must be sha256:<64 hex> (test fixture corrected to a full digest); cross-instance staking-provider contradictions are fail-closed (last claim no longer wins). P1 — no collector lock across network calls (net-new 2): - Identity verification runs BEFORE the central-state lock (verify first, apply under lock) so a degraded RPC never blocks readers; the RPC timeout derives from the passed-in context (CollectContext(ctx), IdentityVerifier now takes ctx, ethCall uses context.WithTimeout(ctx, ...)). P1 — monitoring deployment wiring (finding 6): - A non-loopback API bind without an allowlist is refused at startup. - cutover-readiness.json added to the Grafana ConfigMap; instance-reason text panel replaced with a real table sourced from the readiness API via a new Infinity datasource (+ plugin install). - Added a cutover-roster Deployment/Service/PVC and a Prometheus scrape job, plus an Alertmanager workload + routing tree matching the alerts' route_to label. (Image digest, allowlist CIDR, inventory ConfigMap/Secret, and receiver integrations are REPLACE_ placeholders — ops follow-up, documented in README.adoc.) P1 — 30-day resolved purge (net-new 3): resolution of the semantic conflict. - The fail-closed reopening of a vanished resolved operator (finding 2, RESOLVED) and the naive 30-day purge of a departed resolved operator are in genuine, irreconcilable tension for the "resolved operator departs" population: a departed operator MUST reopen offline_unknown and be retained indefinitely, so it can never age out via the resolved path, and an actively-resolved operator is continuously re-confirmed (ResolvedAt refreshed) and must not be dropped. purge therefore remains a bounded-store backstop for a resolved record no longer being re-confirmed. Restored independent coverage as a white-box test of the purge mechanism (TestCollector_PurgeResolvedAfter30Days): a resolved record older than the retention window is purged with its instances, while a fresh resolved record and any blocking record are retained. P1/P2 — harness: README/compose/script examples now use an immutable @sha256: digest instead of the mutable keep-client:candidate tag the harness itself rejects. P2 — draft PR body: corrected the inaccurate "wire-compatible / no session-ID/KDF change" claim to scope it to THIS diff only and explicitly note PR #4109's Part A cryptographic changes are wire-breaking and not described here.

Two same-operator inventory entries with empty network IDs and one shared target could both be certified by a single responding node. Now: - NetworkID is a required, unique inventory field whenever the trust chain is enforced (RequireIdentityVerification || RequireServiceDiscovery): a missing or duplicated per-instance network ID is a fail-closed reconciliation fault, so two instances can no longer collapse (collector.go). - The metrics adapter binds each report to the responding node's OWN attested network ID unconditionally — inventory must pin it, the node must attest it, and the two must match — and stores the node's value on the report; InstanceID is only an inventory label, never the trust identity (reportadapter.go, types.go). - Discovery-disappearance reconciliation is keyed by the full (operator, network ID) tuple via ServiceDiscovery.HasInstance, so a sibling instance's presence no longer covers a distinct instance (servicediscovery.go). - Service discovery is authoritative for the report target: a discovered per-instance target overrides any inventory-supplied trusted_report_target, and an undiscovered instance is left untargeted, closing the explicit-target bypass (cmd/cutover-roster/main.go). - The self-declared "json" report mode cannot prove a node's own per-instance identity, so it is refused rather than left as a silent gap in complete=true; only the identity-validating "metrics" mode remains (cmd/cutover-roster/main.go). - New end-to-end regression test proves one responding node cannot certify two distinct same-operator instances (empty-network-id collapse and distinct-id cases), plus a positive control that a legitimate node-attested instance still resolves (production_integration_test.go). P1 — make the monitoring deployment internally deployable (finding 6). - Pin the Grafana Infinity datasource to 2.3.1 (grafanaDependency >=8.4.7), the newest release compatible with the pinned Grafana 9.2.5; an unversioned install resolved to latest, which requires Grafana >= 11.6 (grafana-deployment.yaml). - Serve /healthz OUTSIDE the CIDR allowlist and point the Deployment's liveness/readiness probes at it, so kubelet probes from the node IP no longer hit the allowlist and 403 the pod into permanent unreadiness; the data endpoints (readiness API + /metrics) stay restricted (api.go, deployment.yaml). - Add a CutoverRosterCollectorDown up/absent() alert so a dead or unscraped collector — which makes every performance_cutover_* series vanish — can no longer leave both roster alerts silently absent (alerts.go, rules.yaml).

The gate pins the protocol mode into an immutable per-ceremony permit at issuance, so crossing the cutover block never cancels or reclassifies in-flight work; last-moment commit fences allow legacy completion commits to finish within their existing validity while suppressing new penalty commits at or after the cutover block and during process quiescence, and any synchronous chain-clock failure fails the gate closed by canceling all outstanding permits. Mainnet resolves the compiled constant only and rejects any override by presence, keeping the zero placeholder a release blocker; testnet requires an explicit nonzero rehearsal value; the developer-only zero schedule stays in legacy mode. Gate state, per-mode permit activity, refusal/abort/suppression evidence, and the cutover block itself are exported through the client-info performance registry. --- pkg/clientinfo/performance.go | 74 ++ pkg/protocol/participation/gate.go | 964 ++++++++++++++++ pkg/protocol/participation/gate_test.go | 1097 +++++++++++++++++++ pkg/protocol/participation/release.go | 49 + pkg/protocol/participation/schedule.go | 203 ++++ pkg/protocol/participation/schedule_test.go | 265 +++++ 6 files changed, 2652 insertions(+) create mode 100644 pkg/protocol/participation/gate.go create mode 100644 pkg/protocol/participation/gate_test.go create mode 100644 pkg/protocol/participation/release.go create mode 100644 pkg/protocol/participation/schedule.go create mode 100644 pkg/protocol/participation/schedule_test.go diff --git a/pkg/clientinfo/performance.go b/pkg/clientinfo/performance.go index 8fa41b7bf1..9a5212bb93 100644 --- a/pkg/clientinfo/performance.go +++ b/pkg/clientinfo/performance.go @@ -144,6 +144,16 @@ func (pm *PerformanceMetrics) registerAllMetrics() { MetricAnnouncerCrossFormatPeerTotal, MetricAnnouncerLegacyPeerAdditionsTotal, MetricAnnouncerLegacyPeerEvictionsTotal, + MetricParticipationModeLegacyTotal, + MetricParticipationModeSecurityV2Total, + MetricParticipationLegacyCompletionsAfterCutoverTotal, + MetricParticipationRefusalsTotal, + MetricParticipationCommitRefusalsTotal, + MetricParticipationClockErrorsTotal, + MetricParticipationClockAbortsTotal, + MetricParticipationQuiesceTotal, + MetricParticipationQuiesceForcedAbortsTotal, + MetricHeartbeatPenaltySuppressedTotal, } // Register per-reason network join failure counters @@ -151,6 +161,11 @@ func (pm *PerformanceMetrics) registerAllMetrics() { counters = append(counters, NetworkJoinFailureMetricName(reason)) } + // Register per-ceremony participation refusal counters + for _, ceremony := range GetAllParticipationCeremonies() { + counters = append(counters, ParticipationRefusalMetricName(ceremony)) + } + // First, initialize all counters in the map pm.countersMutex.Lock() for _, name := range counters { @@ -314,6 +329,13 @@ func (pm *PerformanceMetrics) registerAllMetrics() { MetricAnnouncerLegacyPeersCurrent, MetricAnnouncerLegacyPeerOldestAgeBlocks, MetricAnnouncerLegacyPeerRosterRevision, + MetricParticipationGateState, + MetricParticipationCurrentBlock, + MetricParticipationCutoverBlock, + MetricParticipationAllowed, + MetricParticipationActiveCeremonies, + MetricParticipationActiveLegacyCeremonies, + MetricParticipationActiveSecurityV2Ceremonies, } // First, initialize all gauges in the map @@ -714,6 +736,31 @@ const ( MetricAnnouncerLegacyPeerRosterRevision = "announcer_legacy_peer_roster_revision" MetricAnnouncerLegacyPeerAdditionsTotal = "announcer_legacy_peer_additions_total" MetricAnnouncerLegacyPeerEvictionsTotal = "announcer_legacy_peer_evictions_total" + + // Protocol participation gate Metrics + // + // These back the chain-clocked cutover gate: the process participation + // state, the resolved cutover block, per-mode permit activity, and the + // refusal/abort/suppression evidence required for the cutover go/no-go + // and rollback decisions.

charset=UTF-8 Content-Transfer-Encoding: 8bit The cutover schedule resolves at the very beginning of client start, before the Ethereum connection, so a misconfigured cutover block terminates startup before any component can send protocol traffic. Mainnet always uses the compiled release constant: the override is rejected by flag/config-key presence rather than by decoded value, so an explicit zero cannot slip through, and the zero compiled placeholder keeps this artifact a release blocker on mainnet until a reviewed release commit bakes the real block. Testnet rehearsals must supply a nonzero block explicitly; developer mode may use zero to run with the cutover schedule disabled. Command tests cover the presence detection through both the flag and config-file paths — explicit zeros included, since flag binding and Viper unmarshalling have different precedence — and the full per-network resolution matrix. --- cmd/flags.go | 15 ++ cmd/flags_test.go | 234 ++++++++++++++++++++ cmd/start.go | 31 +++ config/category.go | 3 + config/config.go | 27 ++- configs/config.toml.SAMPLE | 8 + docs/resources/client-start-help | 3 +- test/config_participation_cutover.toml | 21 ++ test/config_participation_cutover_zero.toml | 22 ++ 9 files changed, 356 insertions(+), 8 deletions(-) create mode 100644 test/config_participation_cutover.toml create mode 100644 test/config_participation_cutover_zero.toml diff --git a/cmd/flags.go b/cmd/flags.go index 48304cbf8d..b88dab0ff7 100644 --- a/cmd/flags.go +++ b/cmd/flags.go @@ -50,6 +50,8 @@ func initFlags( initTbtcFlags(cmd, cfg) case config.Maintainer: initMaintainerFlags(cmd, cfg) + case config.ProtocolParticipation: + initProtocolParticipationFlags(cmd, cfg) case config.Developer: initDeveloperFlags(cmd) } @@ -375,6 +377,19 @@ func initMaintainerFlags(command *cobra.Command, cfg *config.Config) { ) } +// Initialize flags for Protocol Participation configuration. +func initProtocolParticipationFlags(cmd *cobra.Command, cfg *config.Config) { + cmd.Flags().Uint64Var( + &cfg.ProtocolParticipation.CutoverBlock, + "protocolParticipation.cutoverBlock", + 0, + "Protocol cutover block override for non-mainnet networks.

It sizes rehearsal timing, straggler-roster retention, rollback quiescence deadlines, and long-legacy-overlap alerts, and is deliberately not a second activation height. Same-package drift tests pin every constituent constant and the cross-package assertion pins the combined bound, so a protocol timing change cannot silently invalidate the derived retention and quiesce values. --- cmd/participation_bounds_test.go | 38 +++++++++++++++++++ pkg/beacon/participation.go | 30 +++++++++++++++ pkg/beacon/participation_test.go | 62 +++++++++++++++++++++++++++++++ pkg/tbtc/participation.go | 32 ++++++++++++++++ pkg/tbtc/participation_test.go | 64 ++++++++++++++++++++++++++++++++ 5 files changed, 226 insertions(+) create mode 100644 cmd/participation_bounds_test.go create mode 100644 pkg/beacon/participation.go create mode 100644 pkg/beacon/participation_test.go create mode 100644 pkg/tbtc/participation.go create mode 100644 pkg/tbtc/participation_test.go diff --git a/cmd/participation_bounds_test.go b/cmd/participation_bounds_test.go new file mode 100644 index 0000000000..ef490f0e9c --- /dev/null +++ b/cmd/participation_bounds_test.go @@ -0,0 +1,38 @@ +package cmd + +import ( + "testing" + + "github.com/keep-network/keep-core/pkg/beacon" + beaconchain "github.com/keep-network/keep-core/pkg/beacon/chain" + "github.com/keep-network/keep-core/pkg/tbtc" +) + +// TestMaximumLegacyCompletionBlocksAcrossProtocols is the cross-package drift +// assertion for the combined in-flight completion bound: the starting input +// for quiesce deadlines, roster retention, and the release-manifest grace +// derivation.

charset=UTF-8 Content-Transfer-Encoding: 8bit DKG and signing attempt session IDs now derive from an explicit protocol compatibility mode: the legacy form reproduces the pre-hardening production announcements byte-for-byte — the signing form carries no attempt start block — so a legacy-mode ceremony interoperates with prior-release peers, while the security-v2 form keeps the hardened protocol-named, fixed-width shape. An unset mode fails loudly instead of silently picking a wire format. The retry loops carry the mode as an immutable field so every attempt of a ceremony — including attempts starting at or after the cutover block — announces under the one mode the ceremony was pinned to. The executors currently pin security-v2 explicitly; the ceremony permit will supply the anchored mode once the gate is threaded through the executors. Byte tests pin both forms exactly and cross-check them against the announcer's wire-format classifier. --- pkg/tbtc/dkg.go | 1 + pkg/tbtc/dkg_loop.go | 52 +++++++++++++-- pkg/tbtc/dkg_loop_test.go | 24 +++---- pkg/tbtc/session_id_test.go | 120 ++++++++++++++++++++++++++++++++++ pkg/tbtc/signing.go | 1 + pkg/tbtc/signing_loop.go | 45 +++++++++++-- pkg/tbtc/signing_loop_test.go | 30 +++++---- 7 files changed, 235 insertions(+), 38 deletions(-) create mode 100644 pkg/tbtc/session_id_test.go diff --git a/pkg/tbtc/dkg.go b/pkg/tbtc/dkg.go index 06c6a38107..9f4acb8535 100644 --- a/pkg/tbtc/dkg.go +++ b/pkg/tbtc/dkg.go @@ -396,6 +396,7 @@ func (de *dkgExecutor) generateSigningGroup( retryLoop := newDkgRetryLoop( dkgLogger, seed, + participation.ModeSecurityV2, startBlock+delayBlocks, memberIndex, groupSelectionResult.OperatorsAddresses, diff --git a/pkg/tbtc/dkg_loop.go b/pkg/tbtc/dkg_loop.go index dbee414f92..68c8805a03 100644 --- a/pkg/tbtc/dkg_loop.go +++ b/pkg/tbtc/dkg_loop.go @@ -11,6 +11,7 @@ import ( "github.com/keep-network/keep-core/pkg/chain" "github.com/keep-network/keep-core/pkg/protocol/announcer" "github.com/keep-network/keep-core/pkg/protocol/group" + "github.com/keep-network/keep-core/pkg/protocol/participation" "github.com/keep-network/keep-core/pkg/tecdsa/dkg" "github.com/keep-network/keep-core/pkg/tecdsa/retry" "golang.org/x/exp/slices" @@ -60,6 +61,12 @@ type dkgRetryLoop struct { // Used for the announcement.

Clock samples now carry tickets taken before each read starts and only the newest sample can change state, so a stale success can never mask a newer failure and a stale failure cannot spuriously cancel permits; the operation owning a failed or superseded read still fails closed with the clock sentinel. The cutover-block waiter no longer recovers availability or advances the current height itself: it only requests an authoritative synchronous poll, since waiter delivery is transition telemetry, not evidence the synchronous clock works. A waiter that closes early takes a fresh ticket so in-flight reads cannot mask the failure. Every applied height — including the one read at gate construction — is now validated against the exact float64 metrics projection bound; an unprojectable height is handled as a clock failure instead of being exported imprecisely. The concurrency test now genuinely overlaps permit issuance, commit fences, the cutover crossing, quiescence, and the terminal close, and asserts every fence outcome against the exact allowed sentinel set instead of discarding results. New deterministic held-read tests pin both stale-sample orderings, the waiter-with-failing-read path, the waiter-with-lagging-read path, and the unprojectable-height paths. --- pkg/protocol/participation/gate.go | 128 ++++-- pkg/protocol/participation/gate_test.go | 547 ++++++++++++++++++++++-- pkg/protocol/participation/mode.go | 28 +- pkg/protocol/participation/schedule.go | 17 +- 4 files changed, 629 insertions(+), 91 deletions(-) diff --git a/pkg/protocol/participation/gate.go b/pkg/protocol/participation/gate.go index af8a0bd9e0..ef37ccd5dd 100644 --- a/pkg/protocol/participation/gate.go +++ b/pkg/protocol/participation/gate.go @@ -5,6 +5,7 @@ import ( "errors" "fmt" "sync" + "sync/atomic" "time" "github.com/ipfs/go-log/v2" @@ -248,7 +249,14 @@ type chainGate struct { closeOnce sync.Once + // clockSeq issues the ordering tickets for synchronous clock reads.

The derivation now rejects nil, non-positive group sizes, and both overflow cases. The beacon drift tests previously asserted against injected literal values, so a change in the production Ethereum adapter configuration would not fail them. The 136-block assertion and the cross-package aggregate now derive their configuration from the Ethereum adapter's GetConfig, and the adapter inputs themselves are pinned as constituents. The tBTC cutover peer roster retention was a separate hard-coded 1200+300 constant that could drift from the protocol validity windows. It is now derived from MaximumLegacyCompletionBlocks plus the reviewed margin with a checked addition, and the derived value is pinned by a test so a change forces a deliberate retention re-review. --- cmd/participation_bounds_test.go | 19 ++++---- pkg/beacon/participation.go | 51 +++++++++++++++++--- pkg/beacon/participation_test.go | 81 ++++++++++++++++++++++++++++---- pkg/tbtc/participation.go | 31 ++++++++++++ pkg/tbtc/participation_test.go | 21 +++++++++ pkg/tbtc/tbtc.go | 17 ++++--- 6 files changed, 187 insertions(+), 33 deletions(-) diff --git a/cmd/participation_bounds_test.go b/cmd/participation_bounds_test.go index ef490f0e9c..ffe1cd417c 100644 --- a/cmd/participation_bounds_test.go +++ b/cmd/participation_bounds_test.go @@ -4,22 +4,25 @@ import ( "testing" "github.com/keep-network/keep-core/pkg/beacon" - beaconchain "github.com/keep-network/keep-core/pkg/beacon/chain" + "github.com/keep-network/keep-core/pkg/chain/ethereum" "github.com/keep-network/keep-core/pkg/tbtc" ) // TestMaximumLegacyCompletionBlocksAcrossProtocols is the cross-package drift // assertion for the combined in-flight completion bound: the starting input // for quiesce deadlines, roster retention, and the release-manifest grace -// derivation.

Selecting those decisions individually could produce a partially legacy ceremony that interoperates with neither release, so they now travel together in an immutable, stateless strategy bundle selected explicitly from a participation mode with no default. altbn128 gains G1HashToPointLegacy, a character-identical transcription of the pre-hardening try-and-increment mapping, with wire-format fixtures pinning its outputs and a divergence check against the counter-based mapping. The tBTC retry-loop session-ID helpers now delegate to the bundle so the exact per-mode formats have a single source of truth. The tECDSA proof-transcript strategy is deliberately absent from the bundle: the pinned tss-lib fork does not yet expose a per-party protocol mode, and extending that fork is reviewed work outside this repository. Until then no production path may hand a legacy bundle to a tECDSA ceremony. --- pkg/altbn128/altbn128.go | 32 +++ pkg/altbn128/altbn128_test.go | 82 +++++++ pkg/protocol/compatibility/strategies.go | 162 +++++++++++++ pkg/protocol/compatibility/strategies_test.go | 216 ++++++++++++++++++ pkg/tbtc/dkg_loop.go | 23 +- pkg/tbtc/signing_loop.go | 28 +-- 6 files changed, 508 insertions(+), 35 deletions(-) create mode 100644 pkg/protocol/compatibility/strategies.go create mode 100644 pkg/protocol/compatibility/strategies_test.go diff --git a/pkg/altbn128/altbn128.go b/pkg/altbn128/altbn128.go index f6471e3679..c3d222ec7d 100644 --- a/pkg/altbn128/altbn128.go +++ b/pkg/altbn128/altbn128.go @@ -161,6 +161,38 @@ func G1HashToPoint(m []byte) *bn256.G1 { panic("G1HashToPoint: no valid curve point found for input") } +// G1HashToPointLegacy hashes the provided byte slice and maps it into a G1 +// point using the pre-hardening try-and-increment approach: the digest is the +// first candidate x-coordinate and is incremented until a quadratic residue +// is found. +// +// It reproduces, byte for byte, the mapping of the production releases that +// precede the counter-based G1HashToPoint, and exists solely so a ceremony +// pinned to the legacy protocol mode by the participation gate remains +// wire-compatible with peers running such a release.

They now come from an explicit per-ceremony compatibility strategy bundle threaded from ExecuteDKG through gjkr.Execute into the member core, so a ceremony pinned to the legacy protocol mode can reproduce the pre-hardening transcript and a security-v2 ceremony keeps the hardened one. A nil bundle is a member construction error: an implicit cryptographic mode is forbidden. The beacon node passes an explicit security-v2 bundle for now, which preserves the current behavior of this branch; the ceremony's participation permit must replace it once the gate is constructed and wired through the node, and the TODO at the call site records that as a release blocker. The DKG test harness pins security-v2 explicitly for the same reason. --- pkg/beacon/dkg/dkg.go | 7 ++++++- pkg/beacon/gjkr/gjkr.go | 8 ++++++++ pkg/beacon/gjkr/member.go | 22 ++++++++++++++++++++-- pkg/beacon/gjkr/message_filter_test.go | 2 ++ pkg/beacon/gjkr/protocol.go | 13 ++++++++----- pkg/beacon/gjkr/protocol_ecdh_test.go | 8 +++++++- pkg/beacon/gjkr/protocol_parameters.go | 14 +++++++++++--- pkg/beacon/gjkr/protocol_sharing_test.go | 7 ++++++- pkg/beacon/node.go | 9 +++++++++ pkg/internal/dkgtest/dkgtest.go | 6 ++++++ pkg/protocol/compatibility/strategies.go | 12 ++++++++++++ 11 files changed, 95 insertions(+), 13 deletions(-) diff --git a/pkg/beacon/dkg/dkg.go b/pkg/beacon/dkg/dkg.go index 5d032a5463..760ec27d6b 100644 --- a/pkg/beacon/dkg/dkg.go +++ b/pkg/beacon/dkg/dkg.go @@ -14,10 +14,13 @@ import ( "github.com/keep-network/keep-core/pkg/beacon/gjkr" "github.com/keep-network/keep-core/pkg/chain" "github.com/keep-network/keep-core/pkg/net" + "github.com/keep-network/keep-core/pkg/protocol/compatibility" "github.com/keep-network/keep-core/pkg/protocol/group" ) -// ExecuteDKG runs the full distributed key generation lifecycle. +// ExecuteDKG runs the full distributed key generation lifecycle.

The client now constructs the gate from the shared Ethereum block counter after the chain connection and before any protocol component starts, performing the first synchronous clock read at construction and refusing startup on a clock error or an unprojectable height. With client-info disabled the gate records to a no-op sink so its state machine and logs still function. Startup now also logs the post-connect derived state, current block, exact revision, compiled epoch, resolved cutover block, its source, and the combined maximum legacy completion bound derived from both protocols.

charset=UTF-8 Content-Transfer-Encoding: 8bit Construct the participation gate and the cutover peer roster immediately after the Ethereum connection and before the network provider starts, so no component can send protocol traffic ahead of the cutover state machine. The client-info registry now starts in two phases — chain-bound observers before the network, network-bound observers right after — so the gate and roster keep a real metrics sink from the first chain-clock read. beacon.Initialize and tbtc.Initialize now require the shared gate (and tBTC the shared roster) instead of tBTC constructing its own roster later; the roster lifecycle and its diagnostics registration move to the process startup that owns them. The retention derivation is exported from tbtc, and the roster's concurrent-close race coverage moves to the roster's own package beside the sweep-loop it exercises. --- cmd/start.go | 186 ++++++++++----- pkg/beacon/beacon.go | 13 ++ pkg/beacon/node.go | 17 +- .../participation/cutover_peer_roster_test.go | 42 ++++ pkg/tbtc/node.go | 21 +- pkg/tbtc/participation.go | 14 +- pkg/tbtc/participation_test.go | 2 +- pkg/tbtc/tbtc.go | 137 +++-------- pkg/tbtc/tbtc_test.go | 219 ------------------ 9 files changed, 246 insertions(+), 405 deletions(-) delete mode 100644 pkg/tbtc/tbtc_test.go diff --git a/cmd/start.go b/cmd/start.go index 51bdf81ba6..bbd67d0fc0 100644 --- a/cmd/start.go +++ b/cmd/start.go @@ -2,6 +2,7 @@ package cmd import ( "context" + "encoding/json" "fmt" "time" @@ -102,57 +103,29 @@ func start(cmd *cobra.Command) error { return fmt.Errorf("error connecting to Ethereum node: [%v]", err) } - netProvider, err := initializeNetwork( - ctx, - []firewall.Application{beaconChain, tbtcChain}, - operatorPrivateKey, - blockCounter, - ) - if err != nil { - return fmt.Errorf("cannot initialize network: [%v]", err) - } - - clientInfoRegistry := initializeClientInfo( - ctx, - clientConfig, - netProvider, - signing, - blockCounter, - ) + // The client-info registry and its chain-bound observers start first: the + // participation gate and cutover roster constructed below need a real + // metrics sink before the network provider exists.

A gate refusal or a missing gate fails participation closed, and permits are released when the member's ceremony work ends. The dkgtest harness accepts a per-member bundle selector, with integration coverage proving a homogeneous legacy ceremony completes, an explicit security-v2 selection matches the default harness, and a mixed-mode cohort below threshold fails closed without publishing a result. Node-level tests drive full ceremonies through a real gate at both sides of the cutover boundary and prove interoperability with standalone legacy members, which fails when the node's bundle does not follow the permit. --- pkg/beacon/gjkr/cutover_integration_test.go | 122 +++++ pkg/beacon/node.go | 63 ++- pkg/beacon/node_cutover_test.go | 508 ++++++++++++++++++++ pkg/internal/dkgtest/assertions.go | 8 + pkg/internal/dkgtest/dkgtest.go | 51 +- 5 files changed, 739 insertions(+), 13 deletions(-) create mode 100644 pkg/beacon/gjkr/cutover_integration_test.go create mode 100644 pkg/beacon/node_cutover_test.go diff --git a/pkg/beacon/gjkr/cutover_integration_test.go b/pkg/beacon/gjkr/cutover_integration_test.go new file mode 100644 index 0000000000..62407a8f63 --- /dev/null +++ b/pkg/beacon/gjkr/cutover_integration_test.go @@ -0,0 +1,122 @@ +package gjkr_test + +import ( + "testing" + + "github.com/keep-network/keep-core/pkg/internal/dkgtest" + "github.com/keep-network/keep-core/pkg/net" + "github.com/keep-network/keep-core/pkg/protocol/compatibility" + "github.com/keep-network/keep-core/pkg/protocol/group" +) + +// TestExecute_HomogeneousLegacy proves the full DKG roundtrip succeeds when +// every member runs the legacy compatibility bundle: the pre-cutover wire +// behavior (legacy ECDH derivation and legacy hash-to-point) is a complete, +// working protocol on the production execution path, not only a set of +// primitive fixtures. +func TestExecute_HomogeneousLegacy(t *testing.T) { + t.Parallel() + + groupSize := 5 + honestThreshold := 3 + seed := dkgtest.RandomSeed(t) + + interceptor := func(msg net.TaggedMarshaler) net.TaggedMarshaler { + return msg + } + + result, err := dkgtest.RunTestWithModes( + groupSize, + honestThreshold, + seed, + interceptor, + func(group.MemberIndex) compatibility.Strategies { + return compatibility.Legacy() + }, + ) + if err != nil { + t.Fatal(err) + } + + dkgtest.AssertDkgResultPublished(t, result) + dkgtest.AssertSuccessfulSignersCount(t, result, groupSize) + dkgtest.AssertMemberFailuresCount(t, result, 0) + dkgtest.AssertSamePublicKey(t, result) + dkgtest.AssertNoMisbehavingMembers(t, result) + dkgtest.AssertValidGroupPublicKey(t, result) +} + +// TestExecute_HomogeneousSecurityV2Explicit proves the same roundtrip with an +// explicitly selected security-v2 bundle for every member.

The sync state machine now executes under the ceremony context, and the beacon DKG threads its permit end to end: the terminal result submission and the signer activation both pass a last-moment completion fence, with no implicit default guard. Interruption after key generation preserves the orphaned signer in a new quarantine namespace beside the active beacon keystore, together with an audit metadata record. The namespace is a sibling directory, so an active-group scan of any release cannot load quarantined outputs as active signers. An accepted result whose local activation the gate refuses is saved durably without cache activation, since dropping an accepted share would permanently reduce its group. Deterministic node-level tests cover a legacy permit completing after the cutover block, forced shutdown and chain-clock failure inside the publication window preserving signers only in quarantine, and mid-GJKR cancellation aborting cleanly with nothing persisted. --- cmd/start.go | 27 +- pkg/beacon/beacon.go | 12 + pkg/beacon/dkg/dkg.go | 82 ++++- pkg/beacon/dkg/dkg_test.go | 5 + pkg/beacon/dkg/result/publish.go | 18 +- pkg/beacon/dkg/result/states.go | 11 + pkg/beacon/dkg/result/submission.go | 33 ++ pkg/beacon/dkg/result/submission_test.go | 228 +++++++++++++ pkg/beacon/gjkr/gjkr.go | 7 +- pkg/beacon/node.go | 130 +++++++- pkg/beacon/node_cutover_test.go | 400 ++++++++++++++++++++++- pkg/beacon/registry/groups.go | 27 ++ pkg/beacon/registry/quarantine.go | 129 ++++++++ pkg/internal/dkgtest/dkgtest.go | 33 ++ pkg/protocol/participation/gate.go | 44 ++- pkg/protocol/state/sync_machine.go | 20 +- pkg/protocol/state/sync_machine_test.go | 60 +++- 17 files changed, 1232 insertions(+), 34 deletions(-) create mode 100644 pkg/beacon/registry/quarantine.go diff --git a/cmd/start.go b/cmd/start.go index cc506cf95a..cb1339bbfc 100644 --- a/cmd/start.go +++ b/cmd/start.go @@ -291,6 +291,7 @@ func start(cmd *cobra.Command) error { } beaconKeyStorePersistence, + beaconQuarantinePersistence, tbtcKeyStorePersistence, tbtcDataPersistence, err := initializePersistence() @@ -322,6 +323,7 @@ func start(cmd *cobra.Command) error { beaconChain, netProvider, beaconKeyStorePersistence, + beaconQuarantinePersistence, scheduler, participationGate, ) @@ -552,6 +554,7 @@ func registerNetworkClientInfo( func initializePersistence() ( beaconKeyStorePersistence persistence.ProtectedHandle, + beaconQuarantinePersistence persistence.ProtectedHandle, tbtcKeyStorePersistence persistence.ProtectedHandle, tbtcDataPersistence persistence.BasicHandle, err error, @@ -561,24 +564,40 @@ func initializePersistence() ( clientConfig.Ethereum.KeyFilePassword, ) if err != nil { - return nil, nil, nil, fmt.Errorf("cannot initialize storage: [%w]", err) + return nil, nil, nil, nil, fmt.Errorf( + "cannot initialize storage: [%w]", + err, + ) } beaconKeyStorePersistence, err = storage.InitializeKeyStorePersistence( "beacon", ) if err != nil { - return nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, fmt.Errorf( "cannot initialize beacon keystore persistence: [%w]", err, ) } + // The quarantine namespace is a sibling of the active beacon keystore, so + // no release's active-group scan — which reads only the "beacon" directory + // — can load a quarantined signer output as an active signer. + beaconQuarantinePersistence, err = storage.InitializeKeyStorePersistence( + "beacon-quarantine", + ) + if err != nil { + return nil, nil, nil, nil, fmt.Errorf( + "cannot initialize beacon quarantine persistence: [%w]", + err, + ) + } + tbtcKeyStorePersistence, err = storage.InitializeKeyStorePersistence( "tbtc", ) if err != nil { - return nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, fmt.Errorf( "cannot initialize tbtc keystore persistence: [%w]", err, ) @@ -586,7 +605,7 @@ func initializePersistence() ( tbtcDataPersistence, err = storage.InitializeWorkPersistence("tbtc") if err != nil { - return nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, fmt.Errorf( "cannot initialize tbtc data persistence: [%w]", err, ) diff --git a/pkg/beacon/beacon.go b/pkg/beacon/beacon.go index 622052dc14..527738d099 100644 --- a/pkg/beacon/beacon.go +++ b/pkg/beacon/beacon.go @@ -34,27 +34,39 @@ const ProtocolName = "beacon" // function receives that exact instance.

Relay entry signing now issues one permit per local membership, with the restart path going through the gate's resume verification against the on-chain request start block. The terminal relay entry submission passes a completion fence. Timeout monitoring holds a permit anchored at the relay request block and fences the report as a penalty commit, so a legacy monitor cannot create new penalty state at or after the cutover block and no monitor can report once quiescence begins. BroadcastChannelForwarderFor returns a lifecycle handle with idempotent Close and a Done channel: the libp2p relay stops on TTL, provider shutdown, or explicit close, and the local provider returns an already-done no-op. Share forwarding runs under a forwarding permit that closes the handle when the gate cancels, and releases the permit when the relay ends on its own. Tests cover the suppressed legacy timeout report after the cutover, the normal report below it, and both directions of the forwarding lifecycle. --- pkg/beacon/beacon.go | 5 +- pkg/beacon/entry/entry.go | 23 ++- pkg/beacon/entry/submission.go | 29 ++- pkg/beacon/node.go | 182 ++++++++++++++++- pkg/beacon/node_cutover_test.go | 304 ++++++++++++++++++++++++++++ pkg/beacon/node_test.go | 42 +++- pkg/clientinfo/metrics_test.go | 4 +- pkg/internal/entrytest/entrytest.go | 38 +++- pkg/net/libp2p/channel_manager.go | 127 ++++++++---- pkg/net/libp2p/libp2p.go | 13 +- pkg/net/local/local.go | 8 +- pkg/net/net.go | 36 +++- pkg/tbtc/dkg_test.go | 7 +- 13 files changed, 748 insertions(+), 70 deletions(-) diff --git a/pkg/beacon/beacon.go b/pkg/beacon/beacon.go index 527738d099..d78d5b05cf 100644 --- a/pkg/beacon/beacon.go +++ b/pkg/beacon/beacon.go @@ -133,7 +133,10 @@ func Initialize( ) }() } else { - go node.ForwardSignatureShares(request.GroupPublicKey) + go node.ForwardSignatureShares( + request.GroupPublicKey, + request.BlockNumber, + ) } go node.MonitorRelayEntry( diff --git a/pkg/beacon/entry/entry.go b/pkg/beacon/entry/entry.go index cd01b53774..24ff1d8f01 100644 --- a/pkg/beacon/entry/entry.go +++ b/pkg/beacon/entry/entry.go @@ -4,6 +4,7 @@ import ( "context" "encoding/hex" "fmt" + "github.com/keep-network/keep-core/pkg/beacon/event" bn256 "github.com/ethereum/go-ethereum/crypto/bn256/cloudflare" @@ -14,6 +15,7 @@ import ( "github.com/keep-network/keep-core/pkg/chain" "github.com/keep-network/keep-core/pkg/net" "github.com/keep-network/keep-core/pkg/protocol/group" + "github.com/keep-network/keep-core/pkg/protocol/participation" ) // RegisterUnmarshallers initializes the given broadcast channel to be able to @@ -29,7 +31,12 @@ func RegisterUnmarshallers(channel net.BroadcastChannel) { // SignAndSubmit triggers the threshold signature process for the // previous relay entry and publishes the signature to the chain as // a new relay entry. +// +// The context bounds the execution and must be the ceremony permit's context: +// canceling it aborts the share exchange and the submission.

The channel is now armed before any component initializes; a signal arriving mid-startup is held and handled by the lifecycle controller once startup completes. The quiesce backstop previously multiplied the completion bound straight into a time.Duration with no overflow check and no block margin. It is now derived at startup from the maximum legacy completion bound plus a reviewed block margin, with every step overflow-checked; an overflowing deadline refuses startup instead of silently truncating the grace period. The startup log records the bound, margin, block-interval bound, and resulting backstop as the same inputs the release manifest derives the external termination grace from. --- cmd/quiesce_lifecycle_test.go | 45 +++++++++++++--- cmd/start.go | 96 ++++++++++++++++++++++++++++------- 2 files changed, 117 insertions(+), 24 deletions(-) diff --git a/cmd/quiesce_lifecycle_test.go b/cmd/quiesce_lifecycle_test.go index d309136430..39adf0f96f 100644 --- a/cmd/quiesce_lifecycle_test.go +++ b/cmd/quiesce_lifecycle_test.go @@ -1,6 +1,7 @@ package cmd import ( + "math" "os" "syscall" "testing" @@ -39,15 +40,20 @@ func TestAwaitQuiesce_BackstopDeadline(t *testing.T) { } // TestQuiesceBackstopDeadline_DominatesCompletionBound pins the wall-clock -// backstop to the block-derived completion bound: the drain must always be -// given at least the conservative wall-clock equivalent of the longest -// legitimately in-flight work, plus the processing margin. +// backstop to the block-derived completion bound plus the reviewed block +// margin: the drain must always be given at least the conservative wall-clock +// equivalent of the longest legitimately in-flight work, plus the margins. func TestQuiesceBackstopDeadline_DominatesCompletionBound(t *testing.T) { bound := uint64(1200) - expected := time.Duration(bound)*quiesceUpperBlockIntervalSeconds* - time.Second + quiesceBackstopMargin + expected := time.Duration(bound+quiesceReviewedMarginBlocks)* + quiesceUpperBlockIntervalSeconds*time.Second + + quiesceBackstopMargin - if got := quiesceBackstopDeadline(bound);

The new participation-state-audit command produces that manifest from a storage snapshot copy: a full file inventory of the beacon, beacon quarantine, and tBTC namespaces with checksums of the at-rest encrypted bytes, plus an interpreted view of the beacon active memberships and quarantined outputs when the storage password is supplied. Every inconsistency is a finding and fails the audit: quarantine metadata without its preserved membership, memberships without metadata, records that cannot be decrypted or decoded, and quarantine state surfacing in the active-group scan. Without the password the tool degrades to a raw inventory and refuses to classify the snapshot as consistent. Chain reconciliation is explicitly out of scope: the manifest records it as not performed and never authorizes activating quarantined material by itself. --- cmd/participation-state-audit/main.go | 514 +++++++++++++++++++++ cmd/participation-state-audit/main_test.go | 257 +++++++++++ scripts/release/pr4109/README.md | 8 + 3 files changed, 779 insertions(+) create mode 100644 cmd/participation-state-audit/main.go create mode 100644 cmd/participation-state-audit/main_test.go diff --git a/cmd/participation-state-audit/main.go b/cmd/participation-state-audit/main.go new file mode 100644 index 0000000000..97e53d34bd --- /dev/null +++ b/cmd/participation-state-audit/main.go @@ -0,0 +1,514 @@ +// Command participation-state-audit classifies a stopped node's persisted +// protocol state for the rollback barrier, without exposing private material. +// +// It inventories the keystore and work namespaces with checksums of the +// at-rest (encrypted) bytes, interprets the beacon active-group namespace and +// the beacon quarantine namespace when the storage password is supplied, and +// reports every inconsistency it finds: quarantined outputs missing either +// their membership record or their audit metadata, records that fail to +// decrypt or decode, and quarantine state visible to the active-group scan. +// +// The tool MUST run against a snapshot copy of the node's storage, never the +// live directory: opening the standard persistence handles creates their +// bookkeeping subdirectories and probes write permission, and a rollback +// audit must not mutate the original evidence. +// +// Chain reconciliation — on-chain wallet registration and beacon group +// acceptance — is deliberately not performed here: this is the offline +// classification step, and its output never authorizes activating any +// quarantined material by itself. +package main + +import ( + "crypto/sha256" + "encoding/hex" + "encoding/json" + "flag" + "fmt" + "io/fs" + "os" + "path/filepath" + "sort" + "strings" + "time" + + "github.com/keep-network/keep-core/config" + "github.com/keep-network/keep-core/pkg/beacon/registry" + "github.com/keep-network/keep-core/pkg/storage" +) + +// manifestSchemaVersion versions the audit manifest document. +const manifestSchemaVersion = uint32(1) + +// The audited namespaces, relative to the storage root.

Both waits now select on the machine context and return the cancellation cause promptly; two held-wait tests pin the behavior before execution and between states. Beacon result and relay event subscriptions also sent on unbuffered channels, so a callback in flight when its consumer returned on cancellation or timeout blocked forever. The three remaining unbuffered subscription channels now carry the same one-slot buffer the relay timeout monitor already uses. --- pkg/beacon/dkg/dkg.go | 4 +- pkg/beacon/dkg/result/submission.go | 4 +- pkg/beacon/entry/entry.go | 4 +- pkg/protocol/state/sync_machine.go | 42 ++++++-- pkg/protocol/state/sync_machine_test.go | 137 ++++++++++++++++++++++++ 5 files changed, 181 insertions(+), 10 deletions(-) diff --git a/pkg/beacon/dkg/dkg.go b/pkg/beacon/dkg/dkg.go index b7b8f66743..514ed44b8b 100644 --- a/pkg/beacon/dkg/dkg.go +++ b/pkg/beacon/dkg/dkg.go @@ -124,7 +124,9 @@ func ExecuteDKG( operatingMemberIndexes := gjkrResult.Group.OperatingMemberIndexes() - dkgResultChannel := make(chan *event.DKGResultSubmission) + // The buffer lets an in-flight event callback complete after the consumer + // returned on cancellation or timeout, instead of blocking forever. + dkgResultChannel := make(chan *event.DKGResultSubmission, 1) dkgResultSubscription := beaconChain.OnDKGResultSubmitted( func(event *event.DKGResultSubmission) { dkgResultChannel <- event diff --git a/pkg/beacon/dkg/result/submission.go b/pkg/beacon/dkg/result/submission.go index d051491e82..6747fe2ba2 100644 --- a/pkg/beacon/dkg/result/submission.go +++ b/pkg/beacon/dkg/result/submission.go @@ -87,7 +87,9 @@ func (sm *SubmittingMember) SubmitDKGResult( ) } - onSubmittedResultChan := make(chan uint64) + // The buffer lets an in-flight event callback complete after the consumer + // returned on cancellation, instead of blocking forever. + onSubmittedResultChan := make(chan uint64, 1) subscription := chainRelay.OnDKGResultSubmitted( func(event *event.DKGResultSubmission) { diff --git a/pkg/beacon/entry/entry.go b/pkg/beacon/entry/entry.go index 24ff1d8f01..a48052a8d1 100644 --- a/pkg/beacon/entry/entry.go +++ b/pkg/beacon/entry/entry.go @@ -56,7 +56,9 @@ func SignAndSubmit( ctx, cancelCtx := context.WithCancel(ctx) defer cancelCtx() - relayEntrySubmittedChannel := make(chan uint64) + // The buffer lets an in-flight event callback complete after the consumer + // returned on cancellation or timeout, instead of blocking forever. + relayEntrySubmittedChannel := make(chan uint64, 1) subscription := beaconChain.OnRelayEntrySubmitted( func(event *event.RelayEntrySubmitted) { relayEntrySubmittedChannel <- event.BlockNumber diff --git a/pkg/protocol/state/sync_machine.go b/pkg/protocol/state/sync_machine.go index 76a94a5a5b..180e28a3e3 100644 --- a/pkg/protocol/state/sync_machine.go +++ b/pkg/protocol/state/sync_machine.go @@ -41,9 +41,11 @@ type SyncMachine struct { // NewSyncMachine returns a new protocol state machine. // // The context passed to NewSyncMachine must be active for the entire lifetime -// of the execution.

charset=UTF-8 Content-Transfer-Encoding: 8bit A termination signal was captured at the top of startup but acted on only after every component had initialized, so an operator's shutdown request during a slow startup left the gate issuing new permits until the end of initialization. The quiesce drive now runs in a dedicated lifecycle controller launched immediately after the gate and its backstop deadline are constructed — before the network provider, beacon, or tBTC can begin protocol work — so the first signal refuses all subsequent permits no matter when it arrives. The controller reports its shutdown cause before canceling the run context, so the main goroutine always prefers the signal report over a bare context end. --- cmd/quiesce_lifecycle_test.go | 104 ++++++++++++++++++++++++++++++ cmd/start.go | 116 ++++++++++++++++++++++++---------- 2 files changed, 186 insertions(+), 34 deletions(-) diff --git a/cmd/quiesce_lifecycle_test.go b/cmd/quiesce_lifecycle_test.go index 39adf0f96f..c4e96c13c1 100644 --- a/cmd/quiesce_lifecycle_test.go +++ b/cmd/quiesce_lifecycle_test.go @@ -1,11 +1,18 @@ package cmd import ( + "context" + "errors" "math" "os" + "strings" "syscall" "testing" "time" + + "github.com/keep-network/keep-core/pkg/chain/local_v1" + "github.com/keep-network/keep-core/pkg/clientinfo" + "github.com/keep-network/keep-core/pkg/protocol/participation" ) func TestAwaitQuiesce_NaturalCompletion(t *testing.T) { @@ -39,6 +46,103 @@ func TestAwaitQuiesce_BackstopDeadline(t *testing.T) { } } +// TestSignalLifecycleController_FirstSignalPreventsNewPermits proves the +// controller acts on the first termination signal the moment it arrives — +// the model of a signal received while startup is still initializing +// components: the gate refuses every subsequent Begin, the in-flight permit +// keeps draining, and only after it completes does the controller report +// shutdown and cancel the run context. +func TestSignalLifecycleController_FirstSignalPreventsNewPermits(t *testing.T) { + localChain := local_v1.Connect(10, 5) + blockCounter, err := localChain.BlockCounter() + if err != nil { + t.Fatal(err) + } + if err := blockCounter.WaitForBlockHeight(1); err != nil { + t.Fatal(err) + } + + gate, err := participation.NewGate( + context.Background(), + participation.Schedule{CutoverBlock: 1_000_000}, + blockCounter, + &clientinfo.NoOpPerformanceMetrics{}, + ) + if err != nil { + t.Fatal(err) + } + defer gate.Close() + + // The in-flight ceremony that must survive the first signal and keep the + // drain open until it completes. + permit, err := gate.Begin(participation.BeaconDKG, 1) + if err != nil { + t.Fatalf("cannot begin the in-flight ceremony: [%v]", err) + } + + runCtx, cancelRunCtx := context.WithCancel(context.Background()) + defer cancelRunCtx() + + signals := make(chan os.Signal, 2) + shutdownChan := startSignalLifecycleController( + runCtx, + cancelRunCtx, + gate, + signals, + time.Hour, + ) + + signals <- syscall.SIGTERM + + // The controller quiesces asynchronously; a Begin that still succeeds + // lost the race with the quiesce transition and its permit is returned + // before retrying.

Findings now go through one mutex, and the manifest carries the snapshot identity (aggregate checksum, root access mode), an expected-layout scan that flags any entry the audit cannot classify, and explicit rollback blockers: the audit exits nonzero until chain reconciliation, Bitcoin reconciliation, the quiescence outcome report, and prior-reader compatibility evidence are supplied and recorded, so inventory alone can never read as rollback-ready. Interpretation now cross-validates what it decodes. Beacon quarantine metadata is checked against its schema version, this release's epoch, the ceremony class, the cutover arithmetic of its recorded mode and anchor, the directory and member file name it is stored under, the decrypted membership it pairs with, and the active namespace — a group present on both sides of the quarantine boundary is the exact ambiguity the quarantine exists to prevent. Active beacon records are checked against their storage location the active scan trusts. tBTC keystore records are decoded with the same full decode the wallet registry loader uses, via a new exported audit decoder proven against the loader fixtures, and the work namespace is classified with unclassifiable records reported. --- cmd/participation-state-audit/main.go | 865 ++++++++++++++++++--- cmd/participation-state-audit/main_test.go | 379 ++++++++- pkg/tbtc/audit.go | 37 + pkg/tbtc/audit_test.go | 53 ++ 4 files changed, 1218 insertions(+), 116 deletions(-) create mode 100644 pkg/tbtc/audit.go create mode 100644 pkg/tbtc/audit_test.go diff --git a/cmd/participation-state-audit/main.go b/cmd/participation-state-audit/main.go index 97e53d34bd..01a1744408 100644 --- a/cmd/participation-state-audit/main.go +++ b/cmd/participation-state-audit/main.go @@ -1,22 +1,31 @@ // Command participation-state-audit classifies a stopped node's persisted // protocol state for the rollback barrier, without exposing private material. // -// It inventories the keystore and work namespaces with checksums of the -// at-rest (encrypted) bytes, interprets the beacon active-group namespace and -// the beacon quarantine namespace when the storage password is supplied, and -// reports every inconsistency it finds: quarantined outputs missing either -// their membership record or their audit metadata, records that fail to -// decrypt or decode, and quarantine state visible to the active-group scan. +// It records the snapshot identity (an aggregate checksum over every at-rest +// file and the root access mode), inventories the keystore and work +// namespaces, flags any entry the expected storage layout does not contain, +// and — when the storage password is supplied — interprets the beacon active, +// beacon quarantine, and tBTC active namespaces with the same decode paths +// the client's own loaders use.

Preflight verifies the per-node config exists before pulling images. The driver gains the missing halves of the rehearsal contract: a validate-evidence stage that checks every produced record against the evidence schema, local proofs extended to the signal lifecycle, held-wait cancellation, state audit, and audit decoder tests, and a manually dispatched workflow that runs the local proofs in the same build image the client CI uses and keeps the container stages BLOCKED-red until the fleet inputs exist. The port smoke harness asserted the participation gate metrics were not exposed, which stopped being true when the gate landed in this tree; the positive-response assertions now require the gate gauges and the participation diagnostics object. Harness and schema comments now describe the rehearsals in their own terms. --- .github/workflows/cutover-rehearsal.yml | 126 ++++++++++++++++++ scripts/release/pr4109/README.md | 77 +++++++---- .../release/pr4109/clientinfo-port-smoke.sh | 32 +++-- scripts/release/pr4109/compose.rehearsal.yaml | 63 ++++++--- scripts/release/pr4109/compose.yaml | 2 +- .../pr4109/rehearsal-evidence.schema.json | 7 +- scripts/release/pr4109/rehearse.sh | 114 +++++++++++----- 7 files changed, 323 insertions(+), 98 deletions(-) create mode 100644 .github/workflows/cutover-rehearsal.yml diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml new file mode 100644 index 0000000000..68e8b0882a --- /dev/null +++ b/.github/workflows/cutover-rehearsal.yml @@ -0,0 +1,126 @@ +name: Cutover Rehearsal + +# Manually dispatched driver for the single-release cutover rehearsal +# scaffold.

From a45d416cf7b07227430e23bdfe68cefa06f8d2d6 Mon Sep 17 00:00:00 2001 From: Leonardo Saturnino Date: Mon, 27 Jul 2026 09:23:41 -0300 Subject: [PATCH 204/433] feat(tbtc): acquire participation permits and commit fences everywhere MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every tBTC ceremony choke point now runs under a permit from the shared release gate, so process quiescence, clock failure, and the active-mode accounting finally see tBTC work: - Each locally controlled DKG member acquires a permit anchored at the DKG started event block immediately before its goroutine; the retry loop, announcer classification, and execution context all derive from the permit, and a gate cancellation is no longer counted as an ordinary DKG failure. - Each wallet action acquires one permit before handler and dispatcher setup, anchored at the proposal-processing start block; the action owns the permit for its whole execution, and its signing and Bitcoin broadcast run on the permit context instead of unowned background contexts. - The coordination procedure runs under a tracking permit anchored at the window's coordination block; its wire format is shared by both releases, so the procedure itself runs in either mode. - The last-moment completion fences guard signer activation, DKG result submission, and every Bitcoin broadcast attempt; the penalty fence guards the heartbeat's consecutive-failure accounting and the terminal inactivity claim submission, so quiescence or a legacy-after-cutover result suppresses new penalty state instead of punishing the grace. - A refused activation preserves the generated share without activating it: durably in the active namespace when the wallet is registered on chain, otherwise in the new protected tbtc-quarantine storage namespace no release's active-wallet scan reads, with audit metadata recording mode, cutover arithmetic, and a seed hash but never raw seeds or shares. - registerSigner is split into durable save and cache activation so the non-activating save path exists. The pinned tss-lib revision has no reviewed per-party legacy mode, so a tECDSA ceremony cannot reproduce the legacy proof transcript. A legacy-mode permit for DKG, signing, heartbeat, or any wallet action is therefore refused outright — emitting the hardened transcript under a legacy permit would produce wire traffic compatible with neither release. The signing executor additionally hard-refuses any non-security-v2 mode as defense in depth. The tbtc block-height wait helper also drains its abandoned waiter on context cancellation, matching the protocol state machine fix. --- cmd/start.go | 26 +- pkg/tbtc/coordination.go | 8 +- pkg/tbtc/coordination_byzantine_test.go | 2 +- pkg/tbtc/coordination_test.go | 2 +- pkg/tbtc/deposit_sweep.go | 14 + pkg/tbtc/deposit_sweep_test.go | 2 + pkg/tbtc/dkg.go | 260 +++++++++- pkg/tbtc/dkg_submit.go | 16 + pkg/tbtc/dkg_submit_test.go | 7 + pkg/tbtc/dkg_test.go | 30 +- pkg/tbtc/heartbeat.go | 47 +- pkg/tbtc/heartbeat_test.go | 9 + pkg/tbtc/inactivity.go | 26 + pkg/tbtc/inactivity_test.go | 12 + pkg/tbtc/moved_funds_sweep.go | 14 + pkg/tbtc/moved_funds_sweep_test.go | 2 + pkg/tbtc/moving_funds.go | 14 + pkg/tbtc/moving_funds_test.go | 2 + pkg/tbtc/node.go | 191 ++++++- pkg/tbtc/node_test.go | 27 +- pkg/tbtc/participation_gate_test.go | 647 ++++++++++++++++++++++++ pkg/tbtc/participation_permit_test.go | 120 +++++ pkg/tbtc/quarantine.go | 135 +++++ pkg/tbtc/redemption.go | 14 + pkg/tbtc/redemption_test.go | 2 + pkg/tbtc/registry.go | 20 +- pkg/tbtc/signing.go | 40 +- pkg/tbtc/signing_test.go | 17 +- pkg/tbtc/tbtc.go | 20 +- pkg/tbtc/wallet.go | 45 +- pkg/tbtc/wallet_test.go | 7 + 31 files changed, 1694 insertions(+), 84 deletions(-) create mode 100644 pkg/tbtc/participation_gate_test.go create mode 100644 pkg/tbtc/participation_permit_test.go create mode 100644 pkg/tbtc/quarantine.go diff --git a/cmd/start.go b/cmd/start.go index 41170d7463..e2e9deec7f 100644 --- a/cmd/start.go +++ b/cmd/start.go @@ -328,6 +328,7 @@ func start(cmd *cobra.Command) error { beaconKeyStorePersistence, beaconQuarantinePersistence, tbtcKeyStorePersistence, + tbtcQuarantinePersistence, tbtcDataPersistence, err := initializePersistence() if err != nil { @@ -377,6 +378,7 @@ func start(cmd *cobra.Command) error { btcChain, netProvider, tbtcKeyStorePersistence, + tbtcQuarantinePersistence, tbtcDataPersistence, scheduler, proposalGenerator, @@ -666,6 +668,7 @@ func initializePersistence() ( beaconKeyStorePersistence persistence.ProtectedHandle, beaconQuarantinePersistence persistence.ProtectedHandle, tbtcKeyStorePersistence persistence.ProtectedHandle, + tbtcQuarantinePersistence persistence.ProtectedHandle, tbtcDataPersistence persistence.BasicHandle, err error, ) { @@ -674,7 +677,7 @@ func initializePersistence() ( clientConfig.Ethereum.KeyFilePassword, ) if err != nil { - return nil, nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, nil, fmt.Errorf( "cannot initialize storage: [%w]", err, ) @@ -684,7 +687,7 @@ func initializePersistence() ( "beacon", ) if err != nil { - return nil, nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, nil, fmt.Errorf( "cannot initialize beacon keystore persistence: [%w]", err, ) @@ -697,7 +700,7 @@ func initializePersistence() ( "beacon-quarantine", ) if err != nil { - return nil, nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, nil, fmt.Errorf( "cannot initialize beacon quarantine persistence: [%w]", err, ) @@ -707,15 +710,28 @@ func initializePersistence() ( "tbtc", ) if err != nil { - return nil, nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, nil, fmt.Errorf( "cannot initialize tbtc keystore persistence: [%w]", err, ) } + // The quarantine namespace is a sibling of the active tbtc keystore, so + // no release's active-wallet scan — which reads only the "tbtc" directory + // — can load a quarantined signer output as an active signer. + tbtcQuarantinePersistence, err = storage.InitializeKeyStorePersistence( + "tbtc-quarantine", + ) + if err != nil { + return nil, nil, nil, nil, nil, fmt.Errorf( + "cannot initialize tbtc quarantine persistence: [%w]", + err, + ) + } + tbtcDataPersistence, err = storage.InitializeWorkPersistence("tbtc") if err != nil { - return nil, nil, nil, nil, fmt.Errorf( + return nil, nil, nil, nil, nil, fmt.Errorf( "cannot initialize tbtc data persistence: [%w]", err, ) diff --git a/pkg/tbtc/coordination.go b/pkg/tbtc/coordination.go index 2dd75e9614..4fd05eb3c1 100644 --- a/pkg/tbtc/coordination.go +++ b/pkg/tbtc/coordination.go @@ -346,8 +346,12 @@ func (ce *coordinationExecutor) walletPublicKeyHash() [20]byte { } // coordinate executes the coordination procedure for the given coordination -// window. +// window.

Every evidence record now has a mandatory JSON schema — decoded strictly, rejecting unknown fields — with a common envelope binding it to this exact audited snapshot by aggregate checksum, and each record's mandated contents are enforced: - The Ethereum reconciliation must cover every persisted tbtc wallet and beacon group and show each registered with an approved DKG settlement. - The Bitcoin reconciliation must attest a complete pending set with a known terminal state per transaction. - The quiescence report must list a known ceremony, mode, and terminal outcome per active permit, and a claimed quarantined DKG output must be matched by preserved quarantine state in the snapshot. - The prior-reader record must show the tested prior release compatible with every schema this release writes, including loading and signing a wallet created after the cutover block. A missing, undecodable, unbound, uncovered, or contradicted record is a rollback blocker; placeholder bytes can no longer authorize the barrier. The audit also interprets the new tbtc-quarantine namespace with the production loader decode, pairing metadata and membership halves and cross-validating schema, release identity, cutover arithmetic, storage location, and active-namespace overlap — and the tbtc active-namespace checks now verify the member file name, the signing-group index bounds, and per-wallet index uniqueness.

The participation gate refuses future anchors, which silently blocked all five wallet actions on the ordinary pre-end-block path. The result processor now waits until the chain reaches the anchor, then acquires the permit against that same block; the coordination-layer context bounds the wait so shutdown drops the action. The routing tests install a real gate over a fast local chain and prove handler invocation through the dispatcher rejected-actions counter instead of passing vacuously on an untouched busy sentinel. Boundary tests pin both sides of the cutover block: an anchor at the cutover dispatches for every action type, an anchor one block below refuses without touching the dispatcher. --- pkg/tbtc/node.go | 38 ++- pkg/tbtc/node_test.go | 367 ++++++++++++++++---------- pkg/tbtc/participation_permit_test.go | 15 +- 3 files changed, 270 insertions(+), 150 deletions(-) diff --git a/pkg/tbtc/node.go b/pkg/tbtc/node.go index b6cd0ab5ab..e8c881abfb 100644 --- a/pkg/tbtc/node.go +++ b/pkg/tbtc/node.go @@ -1099,8 +1099,10 @@ type coordinationLayerSettings struct { ) (*coordinationResult, bool) // processCoordinationResultFn is a function processing the given - // coordination result. + // coordination result.

Publication now concludes first; the activation fence runs afterwards, and every non-activation outcome — a refused submission fence, a canceled permit, or a publication window that closed without an observed submitted result — preserves the share through the interrupted-signer path instead of activating or dropping it. A result submitted by another member still activates the signer, and a failed registration preserves the share as well. Gate-caused cancellations also no longer contaminate ordinary failure telemetry: the signing executor, the wallet-action dispatcher, the deposit sweep and redemption actions, and the coordination executor check the participation-gate cause before counting ordinary failures or timeouts, the transaction executor surfaces the gate sentinel instead of a broadcast timeout, and the sign/broadcast error chains wrap their causes so every layer classifies the outcome the same way. --- pkg/tbtc/coordination.go | 13 +- pkg/tbtc/deposit_sweep.go | 14 +- pkg/tbtc/dkg.go | 264 ++++++++---- pkg/tbtc/heartbeat.go | 5 +- pkg/tbtc/heartbeat_test.go | 5 +- pkg/tbtc/inactivity.go | 13 + pkg/tbtc/moved_funds_sweep.go | 4 +- pkg/tbtc/moving_funds.go | 4 +- pkg/tbtc/node.go | 13 +- pkg/tbtc/participation_gate_test.go | 644 ++++++++++++++++++++++++++++ pkg/tbtc/redemption.go | 14 +- pkg/tbtc/signing.go | 11 + pkg/tbtc/wallet.go | 29 +- 13 files changed, 929 insertions(+), 104 deletions(-) diff --git a/pkg/tbtc/coordination.go b/pkg/tbtc/coordination.go index 4fd05eb3c1..c4b1f58ee1 100644 --- a/pkg/tbtc/coordination.go +++ b/pkg/tbtc/coordination.go @@ -20,6 +20,7 @@ import ( "github.com/keep-network/keep-core/pkg/generator" "github.com/keep-network/keep-core/pkg/net" "github.com/keep-network/keep-core/pkg/protocol/group" + "github.com/keep-network/keep-core/pkg/protocol/participation" "golang.org/x/sync/semaphore" ) @@ -436,7 +437,10 @@ func (ce *coordinationExecutor) coordinate( // occur anyway. cancelCtx() coordinationFailed = true - if ce.metricsRecorder != nil { + // A gate-canceled permit ended the routine; that is not an + // ordinary coordination failure of this node. + if ce.metricsRecorder != nil && + !participation.IsGateRefusal(context.Cause(ctx)) { ce.metricsRecorder.IncrementCounter(clientinfo.MetricCoordinationFailedTotal, 1) } return nil, fmt.Errorf( @@ -461,8 +465,11 @@ func (ce *coordinationExecutor) coordinate( if err != nil { coordinationFailed = true // Record as leader timeout observation, not as a failure of this node. - // The actual failure is on the leader's side. - if ce.metricsRecorder != nil { + // The actual failure is on the leader's side.

The audit now takes the expected Ethereum chain ID, Bitcoin network, exact prior version and revision, and an evidence freshness bound as inputs — each missing one is a rollback blocker — validates every evidence record against them, reconciles active and quarantined outputs one-to-one in both directions, flags registered wallets or groups whose share is preserved only in quarantine, and matches each quarantined quiescence claim by ceremony, protocol mode, and canonical anchor. --- cmd/participation-state-audit/main.go | 371 ++++++++++++++++- cmd/participation-state-audit/main_test.go | 460 ++++++++++++++++++++- 2 files changed, 791 insertions(+), 40 deletions(-) diff --git a/cmd/participation-state-audit/main.go b/cmd/participation-state-audit/main.go index 94201752a1..18d85c800a 100644 --- a/cmd/participation-state-audit/main.go +++ b/cmd/participation-state-audit/main.go @@ -20,12 +20,17 @@ // // Namespace consistency alone is deliberately insufficient for the rollback // barrier.

charset=UTF-8 Content-Transfer-Encoding: 8bit Exercise the cutover acceptance cases that are provable in-repository with the production announcer and retry loops over real local network providers and real chain-clocked participation gates: a homogeneous security-v2 signing succeeds for an anchor at the cutover block with a late callback; a legacy-anchored ceremony keeps the exact prior-release session IDs through retry attempts that start after the block while the permit's mode never mutates; a post-cutover cohort split by prior-release peers exhausts retries below threshold with no signature and turns the stragglers into mismatch metrics and roster evidence; the loops never invoke the signing or DKG protocol below their threshold/quorum, and at quorum exclude exactly the legacy seat that feeds the misbehaved-members output; and gate-caused aborts leave the ordinary failure counters untouched. The cases that need a completed legacy tECDSA transcript — prior/R1 interop before the cutover and legacy completion with legacy peers — are recorded as explicit skips: they stay blocked until the externally reviewed tss-lib fork with an immutable per-party legacy mode is pinned, and until then the executors deliberately fail closed on legacy permits. --- pkg/tbtc/dkg_cutover_integration_test.go | 920 ++++++++++++++++++ pkg/tbtc/signing_cutover_integration_test.go | 932 +++++++++++++++++++ pkg/tbtc/signing_test.go | 11 +- 3 files changed, 1862 insertions(+), 1 deletion(-) create mode 100644 pkg/tbtc/dkg_cutover_integration_test.go create mode 100644 pkg/tbtc/signing_cutover_integration_test.go diff --git a/pkg/tbtc/dkg_cutover_integration_test.go b/pkg/tbtc/dkg_cutover_integration_test.go new file mode 100644 index 0000000000..710cfa62a4 --- /dev/null +++ b/pkg/tbtc/dkg_cutover_integration_test.go @@ -0,0 +1,920 @@ +package tbtc + +// This file carries the in-repository part of the tBTC DKG cutover acceptance +// evidence: the production DKG retry loop and announcer over real local +// network providers, and real participation gates clocked by a local chain. +// +// The cases that require completing an actual tECDSA key-generation +// transcript are out of unit-suite reach: the legacy transcript is blocked on +// the reviewed tss-lib fork with an immutable per-party legacy mode, and the +// homogeneous full-crypto controls (and the on-chain 90-active/10-misbehaved +// consequence with reward ineligibility) belong to the exact-image rehearsal +// in scripts/release/pr4109 and the Solidity suite.

A second case converts a silent post-cutover peer into real misbehavior evidence: the live members exclude it at quorum, complete the transcript without it, report it in the result's misbehaved members, and resolve the reduced final signing group with remapped indexes. The executors restore fixture pre-parameters through the pool's ordinary persistence restart path, so no CPU-intensive pre-parameters generation runs in the suite, and the persistence mock now implements Delete, which that path exercises.

The security-v2 bundle binds the GG20 proof challenges to the ceremony session exactly as before; the legacy bundle fails closed with a dedicated sentinel at the crypto boundary, because the pinned tss-lib revision exposes no reviewed legacy transcript. This confines the remaining legacy-interoperability work to the reviewed dual-mode tss-lib fork itself: once pinned, the fork's legacy-mode configuration replaces the one refusing bundle method and the executor early refusals, and no other integration point needs to change. A repository ownership check enforces the boundary: setting the GG20 proof-binding nonce, invoking the ephemeral ECDH derivation, or constructing TSS parameters outside the strategy bundle and the two member files now fails the compatibility test suite. --- pkg/internal/signingtest/signingtest.go | 2 + pkg/protocol/compatibility/strategies.go | 89 +++++++++-- pkg/protocol/compatibility/strategies_test.go | 85 ++++++++++ .../transcript_ownership_test.go | 145 ++++++++++++++++++ pkg/tbtc/dkg.go | 14 ++ pkg/tbtc/dkg_cutover_integration_test.go | 7 + pkg/tbtc/signing.go | 13 ++ pkg/tecdsa/common/compatibility.go | 37 +++++ pkg/tecdsa/dkg/dkg.go | 8 + pkg/tecdsa/dkg/member.go | 20 ++- pkg/tecdsa/dkg/member_test.go | 39 +++++ pkg/tecdsa/dkg/protocol.go | 6 +- pkg/tecdsa/dkg/protocol_test.go | 2 + pkg/tecdsa/signing/member.go | 27 +++- pkg/tecdsa/signing/member_test.go | 39 +++++ pkg/tecdsa/signing/protocol.go | 6 +- pkg/tecdsa/signing/protocol_test.go | 21 ++- pkg/tecdsa/signing/signing.go | 8 + pkg/tecdsa/signing/states.go | 7 +- scripts/release/pr4109/README.md | 50 +++--- 20 files changed, 579 insertions(+), 46 deletions(-) create mode 100644 pkg/protocol/compatibility/transcript_ownership_test.go create mode 100644 pkg/tecdsa/common/compatibility.go diff --git a/pkg/internal/signingtest/signingtest.go b/pkg/internal/signingtest/signingtest.go index 82a99aba8b..6babca891d 100644 --- a/pkg/internal/signingtest/signingtest.go +++ b/pkg/internal/signingtest/signingtest.go @@ -27,6 +27,7 @@ import ( "github.com/keep-network/keep-core/pkg/internal/tecdsatest" netLocal "github.com/keep-network/keep-core/pkg/net/local" "github.com/keep-network/keep-core/pkg/operator" + "github.com/keep-network/keep-core/pkg/protocol/compatibility" "github.com/keep-network/keep-core/pkg/protocol/group" "github.com/keep-network/keep-core/pkg/tecdsa" "github.com/keep-network/keep-core/pkg/tecdsa/signing" @@ -173,6 +174,7 @@ func RunTestWithTimeout( []group.MemberIndex{}, // no statically-excluded members broadcastChannel, membershipValidator, + compatibility.SecurityV2(), ) mutex.Lock() diff --git a/pkg/protocol/compatibility/strategies.go b/pkg/protocol/compatibility/strategies.go index f5e2cba489..5d2068426d 100644 --- a/pkg/protocol/compatibility/strategies.go +++ b/pkg/protocol/compatibility/strategies.go @@ -3,10 +3,11 @@ // with exactly one bundle — legacy or security-v2 — selected from its // participation permit's pinned protocol mode, and every wire- and // transcript-sensitive decision travels together inside that bundle: the -// announcement session-ID formats, the ECDH symmetric-key derivation, and the -// G1 hash-to-point mapping.

charset=UTF-8 Content-Transfer-Encoding: 8bit The local proofs covered the Go cutover suites but left the rest of the release evidence to memory: no Solidity run, no static analyzers, no compile proof for the integration-tagged files, and skipped acceptance cases visible only to whoever read the raw log. rehearse.sh now runs the tBTC cutover selection verbosely and ends local-proofs with an explicit report of every skipped case, type-checks the integration-tagged packages so a signature drift cannot hide behind the build tag, and gains two sibling stages: static-analysis, running the CI-enforced analyzers at their CI-pinned versions and flags (gofmt, go vet, staticcheck 2025.1.1, gosec with the CI exclusions, golangci-lint v2.12.2), and solidity-proofs, building and testing the ECDSA contracts exactly as the contracts workflow does on Node 18. The first static-analysis run immediately earned its keep: gosec flagged the state-audit tool's operator-supplied output path, its unchecked stdout write, and its snapshot walk. The walk now rejects non-regular entries before reading — a symlink could point outside the snapshot — the stdout write is checked, and the deliberate operator-path uses carry scoped suppressions with justifications. --- cmd/participation-state-audit/main.go | 19 ++++- scripts/release/pr4109/README.md | 14 +++- scripts/release/pr4109/rehearse.sh | 107 +++++++++++++++++++++++++- 3 files changed, 132 insertions(+), 8 deletions(-) diff --git a/cmd/participation-state-audit/main.go b/cmd/participation-state-audit/main.go index e4830727c6..5c7f8e7fa7 100644 --- a/cmd/participation-state-audit/main.go +++ b/cmd/participation-state-audit/main.go @@ -552,12 +552,17 @@ func main() { encoded = append(encoded, '\n') if outputPath != "" { + // #nosec G703 G304 (manifest destination provided as the operator's + // explicit output flag) if err := os.WriteFile(outputPath, encoded, 0o600); err != nil { fmt.Fprintf(os.Stderr, "cannot write the manifest: [%v]\n", err) os.Exit(1) } } else { - os.Stdout.Write(encoded) + if _, err := os.Stdout.Write(encoded); err != nil { + fmt.Fprintf(os.Stderr, "cannot write the manifest: [%v]\n", err) + os.Exit(1) + } } if !auditManifest.Consistent || !auditManifest.RollbackBarrierReady { @@ -771,7 +776,19 @@ func inventoryNamespace( if entry.IsDir() { return nil } + // A symlink or other non-regular entry could point outside the + // snapshot; such a snapshot cannot be certified. + if !entry.Type().IsRegular() { + return fmt.Errorf( + "cannot inventory [%s]: non-regular entry in the storage "+ + "snapshot", + path, + ) + } + // #nosec G304 G122 (path walked from the snapshot root and + // non-regular entries rejected above; checksumming every snapshot + // file is this audit's purpose) content, err := os.ReadFile(path) if err != nil { return fmt.Errorf("cannot read [%s]: [%w]", path, err) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index 14de9569a0..1b0f2f0555 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -16,14 +16,22 @@ permits, commit fences, quiescence and the signal lifecycle controller, and the signer quarantine namespace — is implemented in this tree and proven by repository-local Go tests, together with the tBTC cutover ceremony acceptance suites under the race detector: real security-v2 key-generation -transcripts, the production-scale 90/10 split exclusion, heartbeat -inactivity bands, and cutover roster wiring.

Every proof stage now refuses to run when PR4109_EXPECTED_SOURCE_COMMIT does not match the tree under test, untracked files included. A build-image binding mode accepts only the divergence the CI image produces by design — .dockerignore'd paths absent from the image and the gen/ trees the image regenerates from published artifacts — and nothing else. The workflow hands the dispatched SHA to all three proof stages, mounts the checkout's .git and scripts/ read-only into the container so the verification runs against the image's own tree, pins every checkout to the dispatched SHA, and archives each stage's log even when the stage fails, because a red run's evidence is the most valuable kind. --- .github/workflows/cutover-rehearsal.yml | 46 +++++++- scripts/release/pr4109/README.md | 23 +++- scripts/release/pr4109/rehearse.sh | 141 ++++++++++++++++++++++-- 3 files changed, 196 insertions(+), 14 deletions(-) diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index 73022b82be..ca6bda897c 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -10,6 +10,15 @@ name: Cutover Rehearsal # rehearsal chain inputs; they report BLOCKED — a failed job — until the # rehearsal fleet inputs exist, because a rehearsal that cannot execute must # never look green. +# +# Provenance is fail-closed: every proof stage receives the dispatched SHA +# in PR4109_EXPECTED_SOURCE_COMMIT and refuses to produce evidence unless +# the tree it is about to test is exactly that commit.

A stamp could therefore certify divergent generated code and could not certify a clean image. The verifier now mirrors the image's construction exactly. It restores the commit's own .gitignore files where absent so build outputs are classified by the commit's rules; accepts deletions only for paths .dockerignore keeps out of the context (honoring the .clusterfuzzlite negations) plus the gen/_address placeholders the generator does not recreate; accepts modifications only for the regenerated binding and _address families, never the negated gen/pb, gen/gen.go, or gen/cmd/cmd.go files the final COPY overwrites with committed bytes; and treats untracked files and every other status as fatal. Each accepted regenerated file is bound into the stamp by committed-vs-image sha256, and the resolved contract artifact tarballs are recorded as the artifact input identity, with the workflow naming ENVIRONMENT explicitly instead of riding the Makefile default. test-source-binding.sh proves the contract over throwaway checkout- and image-shaped repositories — clean image, expected absences alone, build outputs, tampered or missing generated and plain source, tampered ignore rules, missing metadata, SHA mismatch, unknown mode — and runs both as an early workflow step and inside local-proofs so its verdicts land in the archived evidence. A verify-source-binding stage runs the check alone. --- .github/workflows/cutover-rehearsal.yml | 18 + scripts/release/pr4109/README.md | 34 +- scripts/release/pr4109/rehearse.sh | 256 ++++++++++++--- scripts/release/pr4109/test-source-binding.sh | 307 ++++++++++++++++++ 4 files changed, 556 insertions(+), 59 deletions(-) create mode 100755 scripts/release/pr4109/test-source-binding.sh diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index ca6bda897c..0504db2025 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -23,6 +23,10 @@ name: Cutover Rehearsal on: workflow_dispatch: inputs: + artifact_environment: + description: "npm dist-tag or exact version for the contract artifacts baked into the build image; the stamp records every resolved tarball's name, version, and sha256" + required: false + default: "development" run_container_stages: description: "Run the container rehearsal stages (needs all inputs below)" type: boolean @@ -61,6 +65,14 @@ jobs: echo "version=$(git describe --tags --match "v[0-9]*" HEAD)" >> "$GITHUB_ENV" echo "revision=$(git rev-parse --short HEAD)" >> "$GITHUB_ENV" + # The binding verifier gates every piece of evidence this workflow + # archives, so it proves itself before the expensive image build: the + # self-test drives it through checkout- and image-shaped trees and + # fails the dispatch if the verifier accepts anything beyond the + # image's documented construction. + - name: Self-test the source binding verifier + run: ./scripts/release/pr4109/test-source-binding.sh + - name: Set up Docker Buildx uses: docker/setup-buildx-action@v3 @@ -72,6 +84,11 @@ jobs: restore-keys: | ${{ runner.os }}-buildx- + # ENVIRONMENT names the artifact input identity explicitly instead of + # riding the Makefile's implicit development default (client CI's + # empty build-arg resolves to the same tag).

Nothing regenerated is accepted as found anymore: every such tracked file is restored byte-exact from the dispatched commit (git show against the read-only .git mount, whose HEAD is already proven equal to the dispatched SHA) before any test compiles it, a path that cannot be restored is fatal, and the whole tree is re-checked afterwards so nothing beyond the context-excluded absences — none of which holds compiled Go code — survives. The artifact tarball digests stay in the stamp as the image build's input identity, now forensic context rather than trust. The self-test keeps every prior tamper case failing and now proves the new contract on disk: arbitrary bytes written into all four regenerated families are replaced by the committed bytes before anything could test them, an unrestorable path fails the stage, and an untracked file injected into a binding directory stays fatal. --- .github/workflows/cutover-rehearsal.yml | 11 +- scripts/release/pr4109/README.md | 43 +++--- scripts/release/pr4109/rehearse.sh | 124 +++++++++++++----- scripts/release/pr4109/test-source-binding.sh | 99 +++++++++++++- 4 files changed, 214 insertions(+), 63 deletions(-) diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index 0504db2025..6986c3f067 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -24,7 +24,7 @@ on: workflow_dispatch: inputs: artifact_environment: - description: "npm dist-tag or exact version for the contract artifacts baked into the build image; the stamp records every resolved tarball's name, version, and sha256" + description: "npm dist-tag or exact version for the contract artifacts baked into the build image; forensic only — the proof stage restores every regenerated tracked file byte-exact from the dispatched SHA before testing, and the stamp records every resolved tarball's name, version, and sha256" required: false default: "development" run_container_stages: @@ -86,9 +86,12 @@ jobs: # ENVIRONMENT names the artifact input identity explicitly instead of # riding the Makefile's implicit development default (client CI's - # empty build-arg resolves to the same tag).

The default Kubernetes (30s) and systemd (~90s) stop timeouts SIGKILL the process hours before that drain can finish, so the audited forced-cancellation path would never run under an unconfigured service manager. The release manifest closes the gap fail-closed instead of by hand: release-manifest.json records every grace input - both protocol completion bounds with the beacon configuration they came from, the reviewed quiesce margin, block-interval and RPC allowances, and the resulting 19800s backstop - plus the one reviewed input not compiled into the client, the 300s forced-cancellation allowance, giving the 20100s external grace. The new release-manifest subcommand derives the manifest from the compiled bounds and validates any copy against the exact binary, reporting every violation at once through a strict decoder that rejects unknown fields, trailing content, and non-integer numbers. cmd tests pin the checked-in manifest to the compiled bounds and the deploy/ scaffold fragments (Kubernetes patch, systemd drop-in) to the manifest, and the local-proofs stage now runs the manifest and completion-bound drift gates under the race detector, so a changed constant, a stale manifest, and a drifted deployment value all fail the ordinary suite. --- cmd/cmd.go | 1 + cmd/releasemanifest.go | 356 ++++++++++++++ cmd/releasemanifest_test.go | 460 ++++++++++++++++++ scripts/release/pr4109/README.md | 64 ++- ...ep-client-termination-grace.k8s-patch.yaml | 29 ++ ...ient-termination-grace.systemd-dropin.conf | 29 ++ scripts/release/pr4109/rehearse.sh | 2 +- scripts/release/pr4109/release-manifest.json | 22 + .../pr4109/release-manifest.schema.json | 88 ++++ 9 files changed, 1047 insertions(+), 4 deletions(-) create mode 100644 cmd/releasemanifest.go create mode 100644 cmd/releasemanifest_test.go create mode 100644 scripts/release/pr4109/deploy/keep-client-termination-grace.k8s-patch.yaml create mode 100644 scripts/release/pr4109/deploy/keep-client-termination-grace.systemd-dropin.conf create mode 100644 scripts/release/pr4109/release-manifest.json create mode 100644 scripts/release/pr4109/release-manifest.schema.json diff --git a/cmd/cmd.go b/cmd/cmd.go index 0dbe4a24ee..7a5214a6f0 100644 --- a/cmd/cmd.go +++ b/cmd/cmd.go @@ -37,6 +37,7 @@ func init() { EthereumCommand, MaintainerCommand, MaintainerCliCommand, + ReleaseManifestCommand, ) } diff --git a/cmd/releasemanifest.go b/cmd/releasemanifest.go new file mode 100644 index 0000000000..49e86c7f46 --- /dev/null +++ b/cmd/releasemanifest.go @@ -0,0 +1,356 @@ +package cmd + +import ( + "encoding/json" + "errors" + "fmt" + "math" + "os" + "time" + + "github.com/spf13/cobra" + + "github.com/keep-network/keep-core/pkg/beacon" + "github.com/keep-network/keep-core/pkg/chain/ethereum" + "github.com/keep-network/keep-core/pkg/protocol/participation" + "github.com/keep-network/keep-core/pkg/tbtc" +) + +// releaseManifestSchemaVersion is the only release manifest schema this +// binary understands.

The companion `REHEARSAL_KEEP_ETHEREUM_PASSWORD` secret carries the key files' password. +## Release manifest: service-manager termination grace + +A terminating node drains instead of dying: the first SIGTERM quiesces the +participation gate, already-started ceremonies run to natural completion, and +only the in-process backstop — `(maximum legacy completion bound + reviewed +margin) × upper block interval + RPC/processing allowance`, armed by +`quiesceBackstopDeadline` in `cmd/start.go` — forces the remainder through the +audited forced-cancellation path. All of that is useless if the external +service manager SIGKILLs the process first: the Kubernetes default grace is +30 s and systemd's is typically 90 s, both hours short of the drain a node may +legitimately need. The release manifest exists to close that gap fail-closed +rather than by hand-tuned deployment values. + +`release-manifest.json` records every input of the external grace — the tBTC +and beacon completion bounds with the beacon chain configuration they came +from, the reviewed quiesce margin, the upper block interval, the +RPC/processing allowance, and the resulting in-process backstop — plus the one +reviewed input that is not compiled into the client: the forced-cancellation +allowance between the backstop firing and SIGKILL. The authoritative external +grace is the checked sum `in_process_backstop_seconds + +forced_cancellation_allowance_seconds` (currently `19800 + 300 = 20100` +seconds). The client never reads the manifest at runtime; its bounds are +compiled in, and the manifest exists so the SIGKILL deadline is derived from +those same bounds. + +The chain is enforced at three layers, each fail-closed: + +- `keep-client release-manifest derive` prints the manifest derived from the + binary's compiled bounds, and `keep-client release-manifest validate + --manifest ` re-derives every number and rejects the manifest on any + mismatch, reporting every violation at once. Because the subcommand ships in + the client binary, the exact-image rehearsal can validate the manifest with + the very artifact under test. +- `go test ./cmd/ -run TestReleaseManifest` pins the checked-in manifest to + the compiled bounds and the deployment scaffold to the manifest, so a + changed protocol constant, a stale manifest, and a drifted scaffold value + all fail the ordinary test suite; the strict loader additionally rejects + unknown fields, trailing content, and non-integer numbers. The + `local-proofs` stage runs these checks under the race detector. +- `release-manifest.schema.json` describes the document shape for external + tooling; schema validity alone is never authority — only the compiled-bound + validation is. + +`deploy/` carries the two scaffold fragments operators apply, each holding +exactly the manifest's grace: `keep-client-termination-grace.k8s-patch.yaml` +(`spec.template.spec.terminationGracePeriodSeconds`, applied with `kubectl +patch --patch-file`) and `keep-client-termination-grace.systemd-dropin.conf` +(`TimeoutStopSec` plus an explicit `KillSignal=SIGTERM`, installed as a +`.service.d/` drop-in). The grace is a ceiling, not a wait — a node +whose drain completes exits immediately.

With the external grace exactly equal to the sum of the two timed waits, a cleanup consuming its full allowance could still be SIGKILLed mid-teardown, cutting off the quarantine writes the grace exists to protect. The manifest grace now adds a compiled process-exit headroom as a third checked addend (19800 + 300 + 60 = 20160 seconds), the schema and every deployment scaffold carry the new value, the drift tests require the grace to strictly outlast the two waits instead of pinning the unsafe equality, and a lifecycle test walks a forced shutdown from the original termination instant to exit readiness, requiring everything outside the two timed waits to fit within the headroom. --- cmd/quiesce_lifecycle_test.go | 122 +++++++++++++++++- cmd/releasemanifest.go | 47 +++++-- cmd/releasemanifest_test.go | 60 +++++++-- cmd/start.go | 10 +- scripts/release/pr4109/README.md | 46 ++++--- scripts/release/pr4109/compose.rehearsal.yaml | 4 +- ...ep-client-termination-grace.k8s-patch.yaml | 12 +- ...ient-termination-grace.systemd-dropin.conf | 12 +- scripts/release/pr4109/release-manifest.json | 7 +- .../pr4109/release-manifest.schema.json | 10 +- 10 files changed, 268 insertions(+), 62 deletions(-) diff --git a/cmd/quiesce_lifecycle_test.go b/cmd/quiesce_lifecycle_test.go index 77c2b71fa5..833f2baddb 100644 --- a/cmd/quiesce_lifecycle_test.go +++ b/cmd/quiesce_lifecycle_test.go @@ -175,9 +175,11 @@ func TestAwaitForcedCancellationCleanup_AllowanceExceeded(t *testing.T) { // TestForcedCancellationAllowance_BoundToManifestAllowance pins the runtime // phase-two wait to the reviewed allowance the release manifest adds on top -// of the in-process backstop: the wall-clock room the controller actually -// grants the cancellation cleanup must be exactly the room the service -// manager's termination grace reserves for it before SIGKILL. +// of the in-process backstop, and pins the manifest's grace to strictly +// outlast that wait: the room the termination grace reserves after the +// backstop must be the full cleanup allowance the controller actually waits +// plus the positive exit headroom for the teardown running outside both +// timers — never exactly the allowance, or SIGKILL can land inside teardown. func TestForcedCancellationAllowance_BoundToManifestAllowance(t *testing.T) { grace, err := deriveTerminationGrace( defaultForcedCancellationAllowanceSeconds, @@ -197,14 +199,120 @@ func TestForcedCancellationAllowance_BoundToManifestAllowance(t *testing.T) { ) } - graceHeadroom := grace.TerminationGracePeriodSeconds - + graceBeyondBackstop := grace.TerminationGracePeriodSeconds - grace.InProcessBackstopSeconds - if graceHeadroom != uint64(forcedCancellationAllowance()/time.Second) { + runtimeWaitSeconds := uint64(forcedCancellationAllowance() / time.Second) + if graceBeyondBackstop != runtimeWaitSeconds+grace.ProcessExitHeadroomSeconds { t.Errorf( "the termination grace reserves [%d]s after the backstop, but "+ - "the runtime waits [%s]", - graceHeadroom, + "the runtime waits [%s] and the exit headroom is [%d]s", + graceBeyondBackstop, forcedCancellationAllowance(), + grace.ProcessExitHeadroomSeconds, + ) + } + if graceBeyondBackstop <= runtimeWaitSeconds { + t.Errorf( + "the termination grace must reserve strictly more than the "+ + "[%d]s runtime cleanup wait after the backstop, got [%d]s", + runtimeWaitSeconds, + graceBeyondBackstop, + ) + } +} + +// TestSignalLifecycleController_TeardownFitsExitHeadroom walks the forced +// shutdown from the original termination instant to exit readiness — the +// shutdown report delivered and the run context canceled — with both timed +// waits fully consumed by a wedged permit owner, and requires everything +// outside those two waits (controller scheduling, the quiesce and close +// calls, logging, report delivery, context cancellation) to fit within the +// exit headroom the release manifest reserves for it.

Under such a manifest the service manager's SIGKILL deadline ends inside the cleanup wait, recreating the mid-cleanup kill the grace exists to prevent. Derivation inside validation now always consumes the compiled constant and the recorded allowance is checked like every other number, so the coherent rewrite is rejected with both violations named. The derive subcommand loses its allowance flag: the only manifest worth deriving is the one recording the constant the running process honors. The lifecycle test additionally loads the checked-in repository manifest and pins its recorded allowance to the runtime cleanup wait, closing the drift case a purely in-memory derivation cannot see, and new mutation cases prove a lowered, raised, zeroed, or off-by-one allowance all fail validation. --- cmd/quiesce_lifecycle_test.go | 30 +++++++++++-- cmd/releasemanifest.go | 54 ++++++++++++++--------- cmd/releasemanifest_test.go | 82 +++++++++++++++++++++++++++++++++-- cmd/start.go | 11 ++--- 4 files changed, 145 insertions(+), 32 deletions(-) diff --git a/cmd/quiesce_lifecycle_test.go b/cmd/quiesce_lifecycle_test.go index 833f2baddb..b4260438c3 100644 --- a/cmd/quiesce_lifecycle_test.go +++ b/cmd/quiesce_lifecycle_test.go @@ -174,15 +174,18 @@ func TestAwaitForcedCancellationCleanup_AllowanceExceeded(t *testing.T) { } // TestForcedCancellationAllowance_BoundToManifestAllowance pins the runtime -// phase-two wait to the reviewed allowance the release manifest adds on top +// phase-two wait to the compiled allowance the release manifest adds on top // of the in-process backstop, and pins the manifest's grace to strictly // outlast that wait: the room the termination grace reserves after the // backstop must be the full cleanup allowance the controller actually waits // plus the positive exit headroom for the teardown running outside both // timers — never exactly the allowance, or SIGKILL can land inside teardown. +// The same identity is then checked against the checked-in repository +// manifest, so a reviewed document drifting away from the runtime wait fails +// here even though its own numbers are internally coherent. func TestForcedCancellationAllowance_BoundToManifestAllowance(t *testing.T) { grace, err := deriveTerminationGrace( - defaultForcedCancellationAllowanceSeconds, + compiledForcedCancellationAllowanceSeconds, ) if err != nil { t.Fatalf("unexpected derivation error: [%v]", err) @@ -219,6 +222,27 @@ func TestForcedCancellationAllowance_BoundToManifestAllowance(t *testing.T) { graceBeyondBackstop, ) } + + // The derivation above proves the arithmetic; the repository manifest + // must also record exactly the allowance the runtime consumes, otherwise + // the reviewed scaffolds derived from it budget a cleanup window the + // process does not observe.

charset=UTF-8 Content-Transfer-Encoding: 8bit The release-manifest receipt decides which manifest a rehearsal record may be measured against, but it outlived both the run and the commit that produced it. A reused evidence directory kept whichever earlier run had succeeded in it: the proof sequence began without clearing the inherited receipt and only overwrote it at the very end, so a run failing at any proof left its predecessor's receipt standing for the acceptance stage to find. Clear it before proving anything, and publish the new one by a single rename from a staging directory, so a reader sees this run's complete receipt or none. The receipt also named no commit at all. Since a manifest that did not change between two commits hashes the same at both, every comparison the acceptance stage made agreed while the bounds had been compiled somewhere else entirely. Record the commit the binding check proved — not the raw stamp, which calls a legitimately divergent build-image tree dirty — and require it to equal the run's own binding and every record's source_sha, refusing anything but a clean commit id. validate-evidence now verifies its own source binding too: the manifest, schema, and rules it judges by all come out of the tree it runs from, and the workflow hands it the dispatched SHA like every other proof stage. The workflow writes evidence into the workspace root, where a stage's own log counted as the divergence that fails the stage that wrote it; that location needs the ignore rule the script-local one already had. Nine self-test cases cover the new refusals — inherited receipt destroyed, leftover staging directory, missing source stamp, cross-commit receipt, dirty receipt, record from another commit, divergent tree — and the cases now run against throwaway checkouts, so a verdict is the same mid-edit on a workstation and on a bound dispatch. --- .github/workflows/cutover-rehearsal.yml | 9 + .gitignore | 7 +- scripts/release/pr4109/README.md | 75 +++++-- scripts/release/pr4109/rehearse.sh | 178 +++++++++++++-- .../release/pr4109/test-validate-evidence.sh | 202 ++++++++++++++++-- 5 files changed, 417 insertions(+), 54 deletions(-) diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index d777dd92d6..26fbb65c1b 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -138,7 +138,16 @@ jobs: # written by local-proofs into the same bind-mounted evidence # directory, one level down, so it is here and it does not make the # top-level record probe below see a record that does not exist. + # + # The dispatched SHA is handed to this stage like to every other proof + # stage: the manifest, schema, and comparison rules it judges records + # by come out of this checkout, and the attestation and every record it + # accepts must name that same commit.

scaffold's own checkers on every change MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The source-binding verifier and the evidence-record validator decide what may be accepted as release evidence, but everything that exercises them lives in a manually dispatched workflow. A change to either one — or to the workflows around them — could therefore merge unproven, which is the wrong gate for the checkers standing between a rehearsal and a release. Add a shell-analysis stage running bash -n and ShellCheck over every script here, actionlint at a pinned version over the scaffold's own workflows, and both validator self-tests, and run it from a workflow triggered on every push and pull request touching those files. It builds no image and runs no Go suite, so it is cheap enough to require. actionlint is scoped to the two cutover workflows deliberately: the unrelated workflows carry pre-existing findings, and a gate that is red for reasons outside its scope stops being read. The smoke harness's one ShellCheck finding is the deliberate flag-list split it was already making; it now says so. --- .github/workflows/cutover-scaffold-lint.yml | 59 ++++++++++++++++ scripts/release/pr4109/README.md | 25 ++++++- .../release/pr4109/clientinfo-port-smoke.sh | 4 +- scripts/release/pr4109/rehearse.sh | 68 +++++++++++++++++++ 4 files changed, 152 insertions(+), 4 deletions(-) create mode 100644 .github/workflows/cutover-scaffold-lint.yml diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml new file mode 100644 index 0000000000..1b68184817 --- /dev/null +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -0,0 +1,59 @@ +name: Cutover Scaffold Lint + +# The unconditional gate on the cutover rehearsal scaffold itself. +# +# The scaffold's checkers — the source-binding verifier and the +# evidence-record validator — decide what may be accepted as release +# evidence, but everything that exercises them lives in a manually +# dispatched workflow.

What a reused evidence directory actually depends on is the proof stage calling it before the first proof: moving that call after the proofs, or dropping it, left every validator verdict green while a failed proof run went back to leaving its predecessor's receipt standing for the acceptance stage to find and accept in the failed run's name. Extract the stage's proofs into a single seam the self-test can replace, and drive the stage itself with that seam failing the way any proof failure fails it. The case starts from a reused evidence directory holding a valid inherited receipt and requires that the receipt was already gone when the proofs started, that none survives the failure, that the archived proof log records it, and that the acceptance stage is blocked afterwards. --- scripts/release/pr4109/README.md | 17 ++-- scripts/release/pr4109/rehearse.sh | 75 +++++++++-------- .../release/pr4109/test-validate-evidence.sh | 83 +++++++++++++++++-- 3 files changed, 132 insertions(+), 43 deletions(-) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index f1014abd46..e9ce711dcc 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -155,11 +155,18 @@ fields, malformed timestamp, empty record set — over fixture attestations — absent, incomplete, a leftover staging directory, taken over other manifest bytes, contradicting the reviewed bounds, taken at another commit than the run is bound to, taken on a divergent tree, and one differing only in -notes, stamp, and key order — over a divergent tree the stage must refuse -to judge from, and over the invalidation itself, and the stage runs that -self-test first on every invocation.

Nothing held the two together. A rule dropped from .dockerignore leaves the mirror explaining away a file the build context still carries, so the verifier accepts a tree missing it — the one direction that turns real divergence into evidence. The scaffold's own CI gate could not catch that either: it did not run for a change to .dockerignore, to the ignore rules that decide what counts as divergence at all, or to the Dockerfile and Makefile that define what the verifier restores over rather than trusts. Compile the committed .dockerignore the way the build daemon reads it and compare its verdict with the script's for every tracked path, in both the proof stage that produces evidence and the static-analysis gate. The dangerous direction always fails; the safe direction is tolerated only for the families the image regenerates by design. An unmodelled pattern construct, an absent file, and one carrying no rule at all each fail closed. The rules come from the commit rather than from disk, because inside the build image the file is one of the paths its own dotfile rule kept out. The self-test proves each drift is caught, using the checked-in rules and deliberate mutations of them, and refuses to build a case out of a filter that removes no line so a case cannot pass because the rule it targets was renamed. The gate's path filters now cover the build inputs its trust model is derived from as well as its own files. --- .github/workflows/cutover-scaffold-lint.yml | 29 ++- scripts/release/pr4109/README.md | 40 +++- scripts/release/pr4109/rehearse.sh | 223 +++++++++++++++++- scripts/release/pr4109/test-source-binding.sh | 170 ++++++++++++- 4 files changed, 443 insertions(+), 19 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index 1b68184817..5281b24790 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -8,23 +8,46 @@ name: Cutover Scaffold Lint # dispatched workflow.

Three of its readings were not the builder's. It compiled a character class to a literal, while the builder hands the class straight to its expression engine: a rule like `b/[cd]onfig.toml` really does remove `b/config.toml` from the context, and the mirror read it as still there. It normalized a pattern by stripping separators instead of path-cleaning it, so `./scripts/` compiled into an expression matching nothing while the builder removed the whole directory. And it always read the root ignore file, though the builder selects by Dockerfile — a committed `Dockerfile.dockerignore` retires every rule in the root file, and the mirror would have gone on checking itself against rules the build had stopped applying. The classification now cleans each pattern the way the builder does, selects the same file the builder selects, and escapes exactly the characters the builder escapes. What it cannot model it refuses by name rather than guessing: character classes, whose negation form the expression engine reads back to front from the glob grammar the rules are documented in, along with repetitions, alternations, and backslash escapes. A bare `!` fails the build outright, so it fails here too. The scaffold-lint path filters gain the Dockerfile-specific ignore file, because adding one rewrites the entire context classification without touching the file that classification used to be derived from. --- .github/workflows/cutover-scaffold-lint.yml | 11 +- scripts/release/pr4109/rehearse.sh | 198 ++++++++++++++---- scripts/release/pr4109/test-source-binding.sh | 162 ++++++++++++-- 3 files changed, 313 insertions(+), 58 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index 5281b24790..4af9e7d262 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -16,12 +16,17 @@ name: Cutover Scaffold Lint # # The path filters cover the scaffold plus the build inputs its trust model # is derived from, because those decide what it accepts just as directly as -# its own code does: .dockerignore is what the verifier's context -# classification mirrors, the ignore rules decide which working-tree paths +# its own code does: the build's ignore rules are what the verifier's context +# classification mirrors, the gitignore rules decide which working-tree paths # count as divergence at all, and the Dockerfile and Makefile define the # regeneration the verifier restores over rather than trusts.

That Dockerfile was restated beside the classification as a constant, derived once from the rehearsal workflow's build step passing `context: .` and no `file:`. Nothing held the two together: a build step moved onto another Dockerfile would leave the constant behind, and the mirror check would go on passing while reading rules the build had stopped applying — silently, and in the one direction where this scaffold explains a real absence away. Read the identity out of the build step instead: the single docker/build-push-action step's `context` and `file` inputs, taken from the commit under test like the ignore rules themselves. Every step shape the resolution cannot read the way the workflow parser does is refused by name rather than guessed at — a context that is not the repository root, an unset context (the action's default is the Git context, not the checkout), a Dockerfile named by an expression or resolving outside the context or absent from the commit, inputs written as a flow mapping, and more or fewer than one build step. Half the hole is downstream of that: moving the build also moves the ignore file, and the gate that reruns this check only ever runs on the paths its own filters name. So each push and pull_request filter list is held to the resolved identity — both workflows, the resolved Dockerfile, the ignore file that name selects, and the root .dockerignore — or must carry no filter at all, which runs on everything. A paths-ignore list, an empty list, and a workflow reachable only by dispatch each fail closed. The self-test's fixtures now carry both scaffold workflows, and twenty cases move the real build step onto another Dockerfile in another directory: the resolution has to follow it into the ignore file that name selects, a drift there has to fail with the root file intact, and a filter list left behind has to fail closed. Against the previous constant all twenty fail and the existing forty-three still pass. --- .github/workflows/cutover-scaffold-lint.yml | 7 + scripts/release/pr4109/README.md | 42 +- scripts/release/pr4109/rehearse.sh | 478 +++++++++++++++++- scripts/release/pr4109/test-source-binding.sh | 382 +++++++++++++- 4 files changed, 882 insertions(+), 27 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index 4af9e7d262..c2acf8629c 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -27,6 +27,13 @@ name: Cutover Scaffold Lint # Dockerfile-specific one retires every rule in the root .dockerignore for # this build, which rewrites the whole context classification without # touching the file the classification used to be derived from. +# +# These lists are not maintained by hand: shell-analysis resolves the +# Dockerfile the rehearsal workflow's build step really compiles and requires +# both lists below to cover it, the ignore file its name selects, the root +# .dockerignore, and both workflows.

The release was restated as a constant beside the claim, in the stage and again in the dispatch's own setup-node. A bump in CI touches neither, so the claim would survive the job moving and go on being made about a run that no longer reproduces anything. Read it out of the named job instead, and out of that job rather than the workflow around it, whose other jobs pin other releases. The stage resolves it at run time and blocks on any other interpreter; shell-analysis holds the dispatch's own setup-node to the same release, so a bump in CI is caught by the gate that runs on every change rather than by a dispatch nobody ran. A pin loose enough for the runner to choose, one decided by a workflow expression, a job setting up Node twice or not at all, and a renamed or absent job each fail closed. contracts-ecdsa.yml joins the lint's path filters for the same reason the ignore files are there: a change to it rewrites what this scaffold's evidence means without touching a line under scripts/. Placing a step was already solved for the build step, so that logic is now one locator taking a line range, with a job scoper over it. Thirteen cases cover the new claim — including a fixture whose neighbouring jobs pin other releases, so a resolution reading the workflow instead of the job resolves the wrong one. Against no check at all, eleven of the thirteen fail. --- .github/workflows/cutover-rehearsal.yml | 5 + .github/workflows/cutover-scaffold-lint.yml | 14 +- scripts/release/pr4109/README.md | 26 +- scripts/release/pr4109/rehearse.sh | 309 +++++++++++++----- scripts/release/pr4109/test-source-binding.sh | 223 ++++++++++++- 5 files changed, 490 insertions(+), 87 deletions(-) diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index 26fbb65c1b..b604333699 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -202,6 +202,11 @@ jobs: # Node 18.15.0 (18.16+ produced broken hardhat compile artifacts) and # the shared Corepack/immutable-install action, then the stage # revalidates the install and runs the same build and test commands. + # + # The version below is not maintained by hand: shell-analysis reads the + # release that job pins and fails unless this one matches, and the stage + # itself blocks on any other interpreter.

It counted triggers rather than reading them. Any one push or pull_request trigger satisfied it, so a push-only workflow passed — and push fires only after a branch has already moved, which on a repository that merges by pull request means it never fires on the change under review at all. Restrictions inside a trigger were invisible for the same reason: a base-branch filter exempts every pull request into any other branch, and a types list without synchronize runs once when a pull request opens and never again on what is pushed into it afterwards. A pull_request trigger is now required outright, its branch restrictions refused rather than compared against a restated branch name, and its activity types read for the three the event carries when nothing narrows it. It also read the filter list for membership, which is not how the workflow parser reads it: entries are ordered and the last match decides, so a required input listed and then negated further down was reported covered. The list is now compiled to that grammar — `*` stopping at a separator, `**` not, constructs with no reading here refused rather than guessed at — and each required input measured through the whole list in order. The list of inputs it measured was itself kept by hand, and named six paths while the trust model used more: the scaffold's own files, the root and nested gitignore rules deciding what counts as divergence, and the Makefiles running the regeneration the verifier explains absences by. Those are now enumerated out of the commit under test, so adding a gen/Makefile extends what the gate must cover without anyone remembering to say so, and the lint grows the one filter that keeps it covered. Verdicts rise 76 -> 92: one removal per derived class, both negation orders, an unmodelled pattern, and the four trigger shapes that let a change merge ungated. --- .github/workflows/cutover-scaffold-lint.yml | 24 +- scripts/release/pr4109/README.md | 52 ++- scripts/release/pr4109/rehearse.sh | 230 +++++++++++-- scripts/release/pr4109/test-source-binding.sh | 311 +++++++++++++++++- 4 files changed, 555 insertions(+), 62 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index f44541c1e8..e548bede7b 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -28,18 +28,28 @@ name: Cutover Scaffold Lint # this build, which rewrites the whole context classification without # touching the file the classification used to be derived from. # -# These lists are not maintained by hand: shell-analysis resolves the -# Dockerfile the rehearsal workflow's build step really compiles and requires -# both lists below to cover it, the ignore file its name selects, the root -# .dockerignore, and all three workflows.

A workflow firing on every push and pull request touching every derived input, while its job no longer invokes this script, satisfies every rule there and checks nothing — the same ungated state the workflow exists to end, spelled differently. Conditioning the run away, or declaring its failure survivable, gets to the same place while leaving the invocation in place to read. So the invocation is placed and read: exactly one of it, because two leave nothing able to say which placement the conditions belong to; no `if:` on the step or on the job around it; and no `continue-on-error` on either that is not spelled false. Conditions are refused rather than evaluated — nothing here can tell which runs one would hold for, and a gate whose reachability rests on a condition nothing reads is not one this scaffold has proved reachable. A condition on another step is untouched, since the evidence upload runs under always() precisely so a failing analyzer's log survives. The path the invocation is looked for at is this script's own directory and name, so renaming or moving it fails the check rather than quietly leaving it searching for a command nothing runs. Verdicts rise 92 -> 100: no invocation, two invocations, a conditioned step, a conditioned job, a survivable step, a survivable job, and the two shapes that must stay accepted. --- scripts/release/pr4109/README.md | 14 ++ scripts/release/pr4109/rehearse.sh | 146 +++++++++++- scripts/release/pr4109/test-source-binding.sh | 215 +++++++++++++++--- 3 files changed, 337 insertions(+), 38 deletions(-) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index 00c240b1b0..d6e08ff2ec 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -311,6 +311,20 @@ trigger is required outright and refused if it carries `branches` or is pushed into it afterwards.

charset=UTF-8 Content-Transfer-Encoding: 8bit The check holding the scaffold lint to actually running its analysis searched every noncomment line of the workflow for the command text and treated one hit as an invocation. Matching text is not a run: the same characters in a step name, an env: value or an action input label a step that executes nothing, and inside a run: body an echo, a `|| true`, a pipeline, a shell `if`, a `set -n` or a trailing command all leave the text in place while the analysis is either never reached or its exit status never reported. Every one of those satisfied the reading and gated nothing. The invocation is now placed in the only key that runs anything and read there as the shell takes it: lines joined across a trailing backslash, the analysis itself as the body's last command so the step reports its status, and each shape that could condition it or swallow it refused by name. The two ways a body runs under something else are held too — a step shell: is accepted only as the runner's own bash, and defaults: on the job or the workflow is refused rather than followed — and a workflow expression inside the body is read, since the runner writes its value in before the shell parses the line. What none of this can prove is that a run happened, because the check lives behind the invocation it checks: a commit removing the step removes the run that would object. The log now says only what the commit under test says, and the required status check that closes the gap is recorded beside the scaffold rather than implied. --- .github/workflows/cutover-scaffold-lint.yml | 14 + scripts/release/pr4109/README.md | 40 ++ scripts/release/pr4109/rehearse.sh | 476 ++++++++++++++++-- scripts/release/pr4109/test-source-binding.sh | 253 ++++++++++ 4 files changed, 754 insertions(+), 29 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index e548bede7b..f9db5a7adf 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -50,6 +50,20 @@ name: Cutover Scaffold Lint # already moved, so the pull_request event is the only one that can stop a # change to these inputs from merging unchecked, and every restriction of it # exempts some pull request from the gate. +# +# The analysis step below is likewise read rather than found. shell-analysis +# requires it in a step's run: body — the only key that runs anything — as that +# body's last command, unconditioned, unexcused, under the runner's own shell, +# and with nothing around it that could swallow what it says.

The same invocation, spelled character for character as the checked-in one, reaches something else entirely when either changes, so every one of those shapes passed a reading that stopped at the command's text. Refuse them: an `env:` on the step, the job or the workflow, where a BASH_ENV names a file the step's shell sources first and a function defined there can carry the entrypoint's own name; an assignment on the invocation itself, which is the same interception with no key to hold it, so the assignments ahead of the command are now read rather than dropped and only the one environment name this entrypoint documents itself as reading is accepted; a `working-directory:`, since the invocation is a relative path and the directory it resolves from is half of what it names; a job `container:`, which decides both what bash is and what stands at that path; and any `run:` step ahead of the analysis in its job, which can write another file over the entrypoint or write BASH_ENV into the environment every later step inherits. A preceding `uses:` step reaches both just as directly and is still accepted, because refusing it would refuse the checkout the analysis needs to read anything at all. That, and the fact that none of this makes a green conclusion under the gate's name proof that this analyzer ran, are recorded rather than claimed: the stage's own note now says what it did and did not establish. Each of the eight new refusals was verified load-bearing by neutering it and confirming the corresponding case is accepted without it. --- scripts/release/pr4109/rehearse.sh | 192 +++++++++++++++--- scripts/release/pr4109/test-source-binding.sh | 170 ++++++++++++++++ 2 files changed, 336 insertions(+), 26 deletions(-) diff --git a/scripts/release/pr4109/rehearse.sh b/scripts/release/pr4109/rehearse.sh index f2200975b8..83aac3738f 100755 --- a/scripts/release/pr4109/rehearse.sh +++ b/scripts/release/pr4109/rehearse.sh @@ -85,6 +85,18 @@ SCAFFOLD_ENTRYPOINT="$(basename "${BASH_SOURCE[0]}")" # is the one thing about the invocation it cannot read off its own identity.

That overstates what such a rule holds. It requires a conclusion under a job name, and the job producing that conclusion is defined by the same head commit the analysis is reading — a commit keeping the name while its job runs something else reports success and merges. The rule holds the name, not the analysis. Say so, in the workflow's own header and beside the reading it describes, and record the control that does close it — an organisation-level required workflow whose text no pull request into this repository can edit — as an outstanding external dependency rather than a setting assumed to be in place. Its standing is what was actually checkable from outside the organisation: no repository ruleset requires this or any other check, the branch-protection endpoint answers 404 either way, and the required-workflow endpoint needs admin rights nobody here has. Until an admin confirms one, the gate is advisory and evidence resting on its checkers should be read that way. Also document the four shapes the reading now refuses around the invocation, and which one it deliberately still accepts. --- .github/workflows/cutover-scaffold-lint.yml | 21 +++- scripts/release/pr4109/README.md | 116 +++++++++++++++++--- 2 files changed, 114 insertions(+), 23 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index f9db5a7adf..4271ad06b2 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -59,11 +59,22 @@ name: Cutover Scaffold Lint # a `shell:` naming another interpreter, or a step that merely prints this # command all fail the gate closed rather than quietly retiring it. # -# What none of that can prove is that this workflow ran, because the check -# lives behind the invocation it is checking. scaffold-lint MUST therefore be a -# required status check on the protected branches; without that setting a -# commit deleting this file deletes its own enforcement.

That control was retired in October 2023 — configurable via rulesets from 2023-09-20, unreachable from 2023-10-18 — so the record pointed an administrator at a mechanism that can no longer enforce anything, and read a 403 from a withdrawn endpoint as "cannot be confirmed from outside the organisation" when it settles nothing about the control that exists. Name that control instead: the ruleset rule requiring a workflow, spelled "type": "workflows" in the API, with the repository, path and pinned ref or sha each entry carries. Pinning the workflow source outside this repository is not on its own enough, so the record now requires the analyzer to be pinned there too — an immutable workflow that merely invokes the head commit's rehearse.sh runs whatever the commit under test supplies. Enforcement state joins the record for the same reason: a ruleset in evaluate mode reports without blocking, and only active gates a merge. Re-probe the standing through endpoints that still report it. The repository rulesets endpoint with includes_parents pulls in rulesets inherited from the organisation and returns empty, which is the informative negative; the organisation endpoint answers 404 without admin:org, which cannot tell an absent ruleset from an invisible one. Also state where the reading of the workflow stops. Commands ahead of the invocation in the analysis step's own body are read for the shell they open and not for what they write, so a cp over the entrypoint is accepted and the accepted final command then runs the copy. That shape and the preceding uses: step are pinned as accepted cases rather than left for a reader to infer from the absence of one, and the three places describing the reading are held to saying so, so a later rewording cannot grow the refusals into a claim of closure. --- .github/workflows/cutover-scaffold-lint.yml | 15 ++- scripts/release/pr4109/README.md | 108 ++++++++++++------ scripts/release/pr4109/rehearse.sh | 21 ++-- scripts/release/pr4109/test-source-binding.sh | 76 +++++++++++- 4 files changed, 171 insertions(+), 49 deletions(-) diff --git a/.github/workflows/cutover-scaffold-lint.yml b/.github/workflows/cutover-scaffold-lint.yml index 4271ad06b2..225fc6ee65 100644 --- a/.github/workflows/cutover-scaffold-lint.yml +++ b/.github/workflows/cutover-scaffold-lint.yml @@ -67,14 +67,21 @@ name: Cutover Scaffold Lint # the job all fail closed.

An administrator following that record configures the wrong control and the boundary stays open under a record that reads as closed. The record now names the required workflow as a different file, sourced from a repository no pull request into keep-core can write to, carrying the analysis itself rather than calling back into the commit under test. The pin requirement narrows with it: `ref` is documented as a branch or tag and both move, so `sha` is what the record carries, and a tag is admissible only against an active tag ruleset on the source repository holding it immutable. `bypass_actors` and `do_not_enforce_on_create` join `enforcement` in the record, since either leaves an active ruleset gating nothing for the merge that matters. The wording is held rather than left to the next rewording: the three places that describe the control assert both the new distinction and the absence of the phrasing it replaced, so a record that says both — the shape a reader stopping at the first sentence is misled by — fails.

The instances come from `conditions`, which the record did not require: an `active`, unbypassed, externally SHA-pinned entry carrying its own analyzer could satisfy every recorded property while aimed at another repository or at every branch but this one, and satisfy it invisibly, because the record it filled in looked complete. The record now resolves the conditions — which repository selector is in use and that it resolves to this repository, and that `ref_name` matches `refs/heads/main` with neither `exclude` taking it back — and the tag-immutability evidence, the one place a moving pin is admitted, gets the same reading. The same passage filed `do_not_enforce_on_create` beside `bypass_actors` as a second way an active ruleset ends up gating nothing for the merge that matters. It is not one: it waives the rule for the creation of a repository or branch, and a merge into an existing `main` is an update, which it leaves gated. Overstating it there costs in the direction that matters, sending a reader to write off a gate that is standing. It stays in the record for the creation it does reach, and `bypass_actors` is named as the merge-relevant carve-out, down to `bypass_mode`, whose `pull_request` value is the path this merge takes rather than the narrow setting it reads as. Thirteen wording verdicts pin the corrected reading and reject the two prior formulations; restoring either fails exactly those thirteen.

Two of the three do not read that way. `repository_id` carries a `repository_ids` array of integers with no repository-level `exclude` beside it at all, so a reader sent looking for one is looking for a field that cannot exist and the ID itself is the whole test — which is why the resolution the integer withholds is the only thing worth recording there. `repository_property` is a pair over `name`/`property_values` /`source` objects rather than strings, and its `include` is conjunctive where the others are disjunctive; worse for a record meant to fix an aim, it selects whatever set of repositories currently carries those values, so this one can leave that set without the ruleset being touched. A record satisfied by naming the selector alone is satisfied by an aim that moves. The four shapes are now described separately, and the closing requirement asks for the exact `conditions` object plus the evidence resolving the selector to this repository and `ref_name` to `refs/heads/main`, with `ref_name.exclude` — the one exclude present on all three variants — not taking it back. The same passage read `bypass_mode: pull_request` as meaning a listed actor bypasses on every merge into `main`. It means the actor can bypass *only* on pull requests: a restriction on when the capability is available, not a standing waiver. The overstatement costs in an unobvious direction — an administrator who audits a listed actor's merges, finds none bypassed, and concludes the record described something that never happened has been taught to discount the entry. The capability is what makes the actor merge-relevant, so the full actor identity and mode stay required while the prose describes the bypass as available rather than automatic. Two properties that were absent join it: `exempt` runs no rules and writes no bypass audit entry, making it the carve-out that leaves nothing behind to audit, and `pull_request` is applicable only to branch rulesets, which is what makes the tag ruleset's own bypass list unconditional. The field shapes and semantics are read from GitHub's published OpenAPI description rather than from the docs prose. Wording verdicts 162 -> 178, with the two superseded formulations held gone rather than left to sit beside their corrections.

That is the automatic reading, and it contradicted the mode-specific correction sitting directly below it: a `pull_request` actor holds a bypass it has to choose to take, and absent that choice the rules still run on the merge. A record carrying both is read by whoever stops at the first. State the list as what it is in every mode — a grant of permission — and name `bypass_mode` as what governs when that permission is available and whether the actor has to reach for it, which is the one place the three modes genuinely differ: `exempt` is not run at all, `always` is unconditional, `pull_request` lands on a merge the actor still elects. The carve-out is likewise recorded as one that *can* leave an `active` ruleset gating nothing rather than one that does, since whether it does depends on the mode and on the actor. The check moves up with it. The correction was previously pinned only at the `pull_request` sentence, which left the generalisation above it free to reintroduce automatic semantics while every existing assertion went on passing; the new pair holds the capability wording present and the blanket phrase gone. --- scripts/release/pr4109/README.md | 31 ++++++++++--------- scripts/release/pr4109/test-source-binding.sh | 17 +++++++++- 2 files changed, 32 insertions(+), 16 deletions(-) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index 2588777080..7a4196c7d7 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -586,22 +586,23 @@ missing reopens it: Enforcement state belongs in the record rather than being assumed from the ruleset's existence: `enforcement` is one of `disabled`, `active` and `evaluate`, and `evaluate` is a dry run that reports without blocking a merge. -Only `active` gates anything.

The refusal was accurate about the gates not being rehearsable end to end, but it made that the whole answer: the steps that need no legacy capability at all — the crossing of C inside the processes that were already running, a restarted node landing on the same mode from the chain alone, the straggler failing closed and being named by the roster, a severed chain endpoint producing clock_unavailable rather than a guess, shutdown entering quiescence — were refused alongside the ones that genuinely cannot run. A gate that proves half of itself and says so is worth more to a release decision than a gate that says only that it is blocked. Drive each gate as an explicit sequence instead. Every reading comes from the nodes' own client-info ports over the internal rehearsal network, which is what the compose topology already says is the only way in: the gate's live state and roster snapshot from /diagnostics, the participation counters from /metrics, the client's own version and revision rather than an operator's claim about them, and the per-architecture digests behind each immutable reference. The probe attaches to that network rather than to a published host port so a quarantined node is unreachable here because it is off the network, which is what makes the rollback barrier's reachability checks mean anything. The per-step ledger is the point. The record schema already types a step pass, fail, or blocked, so a step this release cannot execute is recorded with its reason and the sequence continues into the independent proofs after it; the run ends by emitting the record and only then deciding the verdict, exiting BLOCKED whenever any mandatory step did not execute. A partial rehearsal can therefore never read as a passed gate, and a blocked gate is never silent about what it did prove. The four legacy-dependent steps of the cutover gate all name one external dependency verbatim, so a reader sees a single missing input rather than a scatter of gaps. Preflight grows the inputs this actually needs and fails closed on each: the probe image digest, the chain id the record carries, a storage snapshot directory for the audit, and a nonzero clientInfo.port declared in every node's own config — the fleet publishes no port to the host, so a node without one can be started but never evidenced, and catching that at preflight beats discovering it mid-rehearsal. Work origination is likewise an input, not an assumption: the fleet only reacts to chain events, so the steps needing a real ceremony record themselves blocked when no driver supplies one. The emitter is proved against the judge rather than against a restatement of the schema. Five cases drive the real ledger and the real emitter with only the two fleet-dependent readings stubbed, and require that a complete run's record passes the acceptance stage untouched, that a run with a blocked step still writes a record and still exits BLOCKED naming that step, that the record types the step blocked rather than smoothing it into a pass, and that a rehearsal on a divergent tree writes nothing at all. --- scripts/release/pr4109/README.md | 37 +- scripts/release/pr4109/rehearse.sh | 924 +++++++++++++++++- .../release/pr4109/test-validate-evidence.sh | 127 +++ 3 files changed, 1054 insertions(+), 34 deletions(-) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index 7a4196c7d7..6c96e5c8ee 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -74,12 +74,25 @@ authorizes activating quarantined material by itself.

The client publishes that object through a struct whose tags lower-case both, so the lookup found nothing on a real node and the emitter would have refused every record at the last step of a completed rehearsal — after the fleet had been driven, quiesced, and torn down. The self-test could not have caught it, because it replaced the whole reader with a fixture and so proved only that some identity reaches the record. Move the substitute down to the transport it sits on: the case now serves the document keep-common actually composes — one key per registered diagnostics source, each source's own JSON nested under it — and the real reader has to find the identity in it. The gate-state reader every rehearsal step decides its outcome from is exercised against the same document for the same reason. Both new checks assert the published values rather than the presence of the schema's required fields, which is what makes a renamed field fail here instead of quietly binding a rehearsal to an empty version. --- scripts/release/pr4109/rehearse.sh | 6 +- .../release/pr4109/test-validate-evidence.sh | 62 +++++++++++++++++-- 2 files changed, 59 insertions(+), 9 deletions(-) diff --git a/scripts/release/pr4109/rehearse.sh b/scripts/release/pr4109/rehearse.sh index b89a378018..2d93d8a356 100755 --- a/scripts/release/pr4109/rehearse.sh +++ b/scripts/release/pr4109/rehearse.sh @@ -2924,13 +2924,13 @@ r1_client_identity() { process.stdin.on("data", (d) => (raw += d)); process.stdin.on("end", () => { const info = (JSON.parse(raw).client_info) || {}; - if (!info.Version || !info.Revision) { + if (!info.version || !info.revision) { console.error("no version/revision in the node diagnostics"); process.exit(1); } process.stdout.write(JSON.stringify({ - version: info.Version, - revision: info.Revision, + version: info.version, + revision: info.revision, })); }); ' diff --git a/scripts/release/pr4109/test-validate-evidence.sh b/scripts/release/pr4109/test-validate-evidence.sh index 4ac276080f..8f3e1d224f 100755 --- a/scripts/release/pr4109/test-validate-evidence.sh +++ b/scripts/release/pr4109/test-validate-evidence.sh @@ -483,12 +483,37 @@ check "the inherited receipt is accepted before any proof run starts" 0 \ # The other side of the same contract: the container rehearsals build the # records this validator judges, so the builder is proved against the judge # rather than against a restatement of the schema.

The client registers all of them through ObserveApplicationSource under the "performance" application, and that call prefixes what it exposes with the application name, so none of the sixteen would have been found on a running node. The silence was the worse half. The reader skipped a metric it could not find, so a wholesale naming mismatch produced steps carrying an empty gauge object — which in the record is indistinguishable from a fleet that reported zeros, and would have been read as evidence. A snapshot that finds none of the sixteen is now a broken instrument and blocks; finding some but not all still records what was there, since a genuinely absent counter is a real observation. The prefix is the one thing the probe cannot read out of the tree, because it reads a running container rather than the source. So it is pinned against the source instead: the self-test requires the prefix to be the application the client registers under, and every probed name to still be a metric the client defines. The exposition fixture serves the prefixed names in the shape keep-common's gauge writes them, so the reader is exercised against the document a node actually serves. --- scripts/release/pr4109/rehearse.sh | 72 ++++++++++++------- .../release/pr4109/test-validate-evidence.sh | 72 +++++++++++++++++++ 2 files changed, 118 insertions(+), 26 deletions(-) diff --git a/scripts/release/pr4109/rehearse.sh b/scripts/release/pr4109/rehearse.sh index 2d93d8a356..af3cdd6baa 100755 --- a/scripts/release/pr4109/rehearse.sh +++ b/scripts/release/pr4109/rehearse.sh @@ -2711,12 +2711,19 @@ participation_field() { ' "${field}" } -# One counter from a node's Prometheus text exposition.

The record validator could not catch it either, because it only asked whether a record was admissible — well formed, from the attested commit, bound to the reviewed manifest — and a record saying a step failed answers all three correctly. Failed steps and refused acceptance assertions are now tracked apart from the blocked ones, and both the run's own exit and the acceptance stage decide from the recorded outcomes by one ordering: a failed step or a refused assertion refuses the gate, a step that never executed leaves it unrehearsed, and only a run with none of the three reports success. A failure outranks an unexecuted step, because reaching a property and watching it break says more than never reaching it. Emission keeps shape-checking its own record so a refused rehearsal still writes the reviewable account of why. What that account then accepts is asked separately, once by the run on its way out and once by the stage a reviewer points at the directory.

The audit that decides whether the state is safe to roll back onto ran with a storage snapshot alone, so it authorized nothing, and its refusal did not stop the prior binary from being started anyway. Fleet startup is now the gate's, not the compose file's: the cutover rehearsal starts the prior straggler it exists to observe, and rollback starts only the release under test. The drain runs while the prior service is sampled from before it begins to after it ends, and the step reports how many samples saw what. The audit runs with the reconciliation, quiescence, prior-reader, and identity inputs it needs, and the prior binary is released only when every R1 node is unreachable and every snapshot reported rollback_barrier_ready — an all-down fleet says two releases cannot write at once, not that what they left is safe to read. The identities the audit binds to, and the epoch and C the record carries, now come from the fleet rather than from the environment: every R1 node is asked, disagreement refuses the run, a revision that is not the bound commit refuses it, and an armed cutover block that is not the rehearsed C refuses it. Capturing that up front is also what lets the rollback gate emit a record at all, since by then it has stopped every node it could ask. --- scripts/release/pr4109/README.md | 48 +- scripts/release/pr4109/rehearse.sh | 421 ++++++++++++++++-- .../release/pr4109/test-validate-evidence.sh | 93 +++- 3 files changed, 515 insertions(+), 47 deletions(-) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index de82d6432f..b9ced3b285 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -72,6 +72,15 @@ release versions, revisions, and immutable image digests, the release epoch, the armed cutover block, and the evidence freshness bound.

The crossing step never established the legacy side of C, so a fleet started after C satisfied it without crossing anything, and it wrote a security-v2 permit mode into the record on the strength of a state string. The homogeneous positive control accepted a zero legacy counter, which is equally true of a fleet that ran nothing. The straggler control accepted any refusal plus a roster object that exists from startup with an empty peer list. Quiescence stopped a node that might be holding nothing, under a restated timeout, and read one state string on the way past. Each now observes its own property. The crossing requires every node to report open_legacy below its armed C first and names a permit mode only where permits were seen. The positive control requires the fleet's security-v2 permit total to rise while the driver runs. The straggler control differences the roster across the driven ceremony and requires an operator the node had not already seen, failing rather than passing when a refusal produces no named operator. Quiescence requires a ceremony in flight when the stop is issued, stops under the reviewed grace, and watches the whole drain for a new permit or a force-aborted held one. Renaming a helper had already left two call sites in the container stages pointing at a function that no longer existed, in code no test here can run. The self-test now resolves every helper those stages name. --- scripts/release/pr4109/README.md | 25 +- scripts/release/pr4109/rehearse.sh | 361 ++++++++++++++---- .../release/pr4109/test-validate-evidence.sh | 36 ++ 3 files changed, 348 insertions(+), 74 deletions(-) diff --git a/scripts/release/pr4109/README.md b/scripts/release/pr4109/README.md index b9ced3b285..670eecb891 100644 --- a/scripts/release/pr4109/README.md +++ b/scripts/release/pr4109/README.md @@ -135,6 +135,24 @@ none of the three reports success.

Each drained node's state is now copied out of the container the drain stopped, before the audit, with the storage path read off the container rather than restated here; a still-running node, a node with anything but one persistent volume, and a copy that fails all refuse rather than produce a snapshot, and a failed capture leaves nothing partial behind. The audit's own result was read the same loose way: it writes to one fixed path per service, so a run that never reached the tool inherited the previous run's manifest, and a nonzero exit was ignored whenever the manifest still said the barrier was ready — which drops the tool's namespace-consistency refusal entirely. The path is cleared first and a nonzero exit now refuses regardless of what the manifest claims. The gate also could not perform the rollback it recorded: the rollback project starts only the R1 services, and `compose start prior-node` has nothing to start in a project where that container was never created. The prior container is now staged — created, proved not running, and proved created from the supplied prior digest — so the barrier's release step acts on a real artifact while the absence the gate exists to prove still holds. Self-test cases drive all of it through the daemon seam: staging that came up running, a create that failed or produced nothing, a container built from other bytes, a live node, a missing and a doubled volume, a failed copy, an inherited capture, an audit that refused while a ready manifest sat at its path, and one that wrote nothing at all. --- scripts/release/pr4109/rehearse.sh | 207 ++++++++++++- .../release/pr4109/test-validate-evidence.sh | 291 ++++++++++++++++++ 2 files changed, 487 insertions(+), 11 deletions(-) diff --git a/scripts/release/pr4109/rehearse.sh b/scripts/release/pr4109/rehearse.sh index eaa79d1eca..076ac72d12 100755 --- a/scripts/release/pr4109/rehearse.sh +++ b/scripts/release/pr4109/rehearse.sh @@ -225,7 +225,11 @@ stages: all-candidate-down barrier, offline state audit, staged prior redeploy, forbidden partial-rollback attempt.

It exposed no probe digest and no chain id, both of which preflight requires; it supplied no work driver, so every step needing a ceremony recorded itself blocked; it supplied none of the reconciliation, quiescence, or prior-reader evidence the rollback audit binds its verdict to; and the manifest attestation each rehearsal's emitter demands was produced in a different job and never carried across, so a rehearsal that got as far as writing a record blocked at the one point a dispatch cannot diagnose from its own log. The rollback step also sat behind a cutover step known to refuse, so the gate whose evidence matters most on a refusal was the one that never ran, and the job archived nothing either way. Every input is now provided or named as missing: the digests and chain identity as dispatch inputs, the chain-side files as one bundle secret whose members are checked as they unpack, and the attestation downloaded from the local-proofs artifact and required before the fleet starts. Rollback runs on whatever verdict the cutover reached and stops only on a failed preflight. Both fleets are torn down and the records and audit manifests are archived whatever happened. Everything provisioned lands outside the checkout. The container stages verify their own source binding before emitting or judging a record and count untracked files as divergence, so a keystore unpacked into the workspace would have failed the stage it was provisioned to enable. The captured node state stays on the runner and is never archived: it holds live protocol state, and what a reviewer needs is the audit manifest over it, which the stage already writes into the evidence directory. --- .github/workflows/cutover-rehearsal.yml | 175 ++++++++++++++++++++++-- scripts/release/pr4109/README.md | 47 +++++++ scripts/release/pr4109/rehearse.sh | 38 +++++ 3 files changed, 249 insertions(+), 11 deletions(-) diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index b604333699..6792bdf127 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -6,11 +6,11 @@ name: Cutover Rehearsal # static analyzers, and the ECDSA contracts build/test, self-tests the # source-binding and evidence-record validators, validates any produced # evidence records against the evidence schema, and archives each stage's -# log for the dispatched SHA.

The clock step drove work before severing the chain endpoint and never offered any afterwards, so its "issued no new permit" rested on nothing having asked — the same reading an idle node produces. It now originates work while the gate reports clock_unavailable and requires a refusal to be recorded against it, because a gate that was never challenged evidences no refusal. Its cancel half read the active-ceremony gauge, which falls when permit owners close them rather than when the gate cancels them, and passed whenever that count fell naturally or became unreadable. It now requires the clock-abort counter to account for every permit the node held. The quiescence step compared an in-flight peak that a permit taken and closed between two samples never raises, never offered work after the node entered quiescing, let an unreadable forced-abort reading fall through to success, and never required the permits it started with to be seen gone. It now offers work once quiescing is observed, decides issuance from the permit counter, blocks on an unreadable counter instead of passing, and requires the in-flight count to have been seen at zero. Both verdicts move into functions that read only their observation slots and touch no fleet, because a ladder this layered is exactly the kind that goes on passing on a proxy until something can drive it directly. Nineteen cases now do: an unchallenged permit counter, work that never reached the gate, a partial cancellation behind a drained and behind an unreadable active count, a permit issued and closed between samples, permits unobserved at zero, and unreadable refusal, issuance, and forced-abort counters. --- scripts/release/pr4109/rehearse.sh | 359 ++++++++++++------ .../release/pr4109/test-validate-evidence.sh | 174 +++++++++ 2 files changed, 415 insertions(+), 118 deletions(-) diff --git a/scripts/release/pr4109/rehearse.sh b/scripts/release/pr4109/rehearse.sh index 9439bbe5d9..102b006fda 100755 --- a/scripts/release/pr4109/rehearse.sh +++ b/scripts/release/pr4109/rehearse.sh @@ -3840,6 +3840,178 @@ that cannot be read leaves the step with no account of what it drove" return "${rc}" } +# What the clock-failure step observed.

So an unrelated gate refusal beside any new roster entry passed it, while a correctly recognized cross-format peer need never have moved it. It now reads the announcer's own account of the sighting and requires the whole chain: a session-ID mismatch arrived, this node recognized it as cross-format, that recognition became a legacy roster addition, and the roster names an operator it had not already seen. Each link is separately refutable, and a mismatch nothing recognized as cross-format is now a failure rather than a gap, because identifying the straggler is the premise. The homogeneous control compared the legacy permit counter against zero. That counter is cumulative over the process, so the pre-C legacy controls this same gate requires would have failed this step the moment they started working — on permits taken before C, not on any sighting after it. It is now a delta across the step like the security-v2 counter beside it. The control also credited the fleet's permit activity to a driver that had reported no transaction at all; it now requires the driver's own account of what it put on the chain before attributing anything to it. Both verdicts move behind the same seam as the clock and quiescence ones, and the announcer metric names are pinned against the client's definitions like the gate's already were, so a rename shows up here rather than as a control that quietly blocks forever. --- scripts/release/pr4109/rehearse.sh | 169 +++++++++++++----- .../release/pr4109/test-validate-evidence.sh | 48 ++++- 2 files changed, 173 insertions(+), 44 deletions(-) diff --git a/scripts/release/pr4109/rehearse.sh b/scripts/release/pr4109/rehearse.sh index 102b006fda..88b2520d7f 100755 --- a/scripts/release/pr4109/rehearse.sh +++ b/scripts/release/pr4109/rehearse.sh @@ -2869,6 +2869,19 @@ PARTICIPATION_METRICS=( participation_quiesce_forced_aborts_total ) +# The announcer's own account of a cross-format sighting, which is a different +# thing from the gate's refusal counter and the only thing that speaks to the +# straggler control.

An empty revision is a prefix of every SHA, so a node reporting nothing passed; short of that, an abbreviation names a commit only as far as it goes. The comparison is now exact. That is only satisfiable if the artifact carries the whole SHA, and the release workflow stamped `git rev-parse --short HEAD` into both images it builds. Both now stamp the full commit, as does the rehearsal workflow's own build image. The revision is a build-arg and an image label, never part of a tag, so nothing downstream reads it positionally. A stamp restated in a scaffold constant would go stale the moment the release pipeline moved, so shell-analysis reads it out of the release workflow at the commit under test and fails on any revision assignment that is not the full SHA — including a release that stopped assigning one, which a check looking only for abbreviations would pass.

A fleet naming the bound commit only in abbreviation is the real one, and it now has a case; a node publishing no revision at all is refused a layer earlier, by the identity reader, and that is now stated rather than left to the comparison that could not have caught it. The divergent-tree case asserted the emitter was where a -dirty run is caught. With an exact comparison the capture refuses first — no node can report a revision equal to a -dirty stamp — so the case now drives both: the capture's refusal, and the emitter's own guard against a divergence that appears after the capture, with the evidence directory required to stay empty either way. The diagnostics fixture defaulted on unset-or-empty, so a case describing a node that publishes nothing was quietly handed the correct value.

A rollback rehearsal runs after a cutover rehearsal, and the cutover fleet is a fleet of the same candidate artifact watching the same rehearsal chain — a distinct project name is a distinct namespace, not a distinct chain, so a candidate another gate left running kept submitting against the same contracts while the prior binary was released beside it. The barrier now enumerates every container the daemon holds that was created from the candidate image or belongs to a rehearsal project of any gate, and requires each to be stopped or attached to no network. Attachment is read from the daemon because a candidate whose client-info listener died is still on the network, and a service that does answer is promoted back to active because a node serving requests is participating whatever the daemon believes. An enumeration that cannot see the containers the asking stage created blocks: an empty active set read from a blind instrument is indistinguishable from a barrier that holds. The cutover stage closes by stopping its own fleet under the reviewed grace and recording the same verdict, and the workflow stops that project again before the rollback gate, so a stage that failed halfway leaves nothing unaccounted for. The decision is a function of its readings alone, so the cases a passing rehearsal never produces — another gate's leftovers, an undescribable container, a blind enumeration — are driven directly. --- .github/workflows/cutover-rehearsal.yml | 16 + scripts/release/pr4109/README.md | 38 ++- scripts/release/pr4109/rehearse.sh | 301 ++++++++++++++++-- .../release/pr4109/test-validate-evidence.sh | 74 +++++ 4 files changed, 386 insertions(+), 43 deletions(-) diff --git a/.github/workflows/cutover-rehearsal.yml b/.github/workflows/cutover-rehearsal.yml index 8f360b6fc7..e22bd4ea55 100644 --- a/.github/workflows/cutover-rehearsal.yml +++ b/.github/workflows/cutover-rehearsal.yml @@ -411,6 +411,22 @@ jobs: id: single_release run: ./scripts/release/pr4109/rehearse.sh single-release + # The cutover fleet stops before the rollback gate starts, and it stops + # here as well as inside the stage that owns it: a single-release stage + # that failed halfway never reached its own closing step, and the fleet + # it left behind is a release candidate watching the same rehearsal chain + # the rollback gate is about to declare quiet.
