fix(desktop): recover failed team membership updates

[storme-square]

The problem

You cannot delete an agent team. Three guards make a cycle:

Command	Message	Location
delete team	N agent(s) still reference it... Delete or reconfigure them first.	desktop/src-tauri/src/managed_agents/teams.rs
delete agent	belongs to a team. Delete the team to remove all team agents together.	desktop/src-tauri/src/managed_agents/personas.rs
delete persona	is still referenced by a team. Remove it from those teams first.	desktop/src-tauri/src/managed_agents/personas.rs

The delete-team command tells you to remove the agents first. The delete-agent command tells you to delete the team first. Thus you cannot do either action.

One sequence breaks the cycle: first remove all the members from the team, then delete the team. The team editor did not permit this sequence. The submit button needed one member or more.

The correction

A team can now have no members. You can then delete the team.

The menu disables Deploy, Duplicate, and Share for a team with no members. Edit and Delete stay enabled. The team card explains the available actions.

The desktop stores the team roster and the agent bindings in separate files. A failed binding write after a roster change used to lose the original membership delta. A retry then could not bind a newly added agent.

The update path now writes a pending membership record before it writes either store. The record contains the team ID and the prior and target rosters. The app removes the record only after it saves the agent bindings.

The next team update, deletion, or app launch replays the original delta under the managed-agent store lock. The replay clears the record when the team write did not land. It also discards and logs a record when an inbound event deleted the team or replaced its roster. The staged delta is not valid in either case.

A membership-changing update now reports every agent-store failure. A metadata-only update still treats an agent-store load failure as best effort.

Tests

• desktop/tests/e2e/agents.spec.ts covers the user sequence: remove every member, save, then delete the team.
• teams_tests.rs covers the update and replay cases, including a failed replacement that must bind the newly added agent.
• migration_tests.rs covers shared worktree synchronization for the pending record.
• teamDialogSelection.test.mjs covers the submit rule.
• teamPersonas.test.mjs covers an empty team.
• team-snapshot.spec.ts covers the share rule.

Verification

Gate	Result
cargo fmt --check --manifest-path desktop/src-tauri/Cargo.toml	passed
cargo test --manifest-path desktop/src-tauri/Cargo.toml --no-fail-fast	2797 passed, 0 failed, 18 ignored
cargo check --manifest-path desktop/src-tauri/Cargo.toml --lib	passed

The local pre-push hook also passed the desktop typecheck, desktop check, desktop test, file-size, branch-skew, and desktop Tauri checks. The repository integration lane could not start because Docker is unavailable on this host.

[P1] Do not report an emptied team as saved while agents still reference it

The new UI treats update_team(... persona_ids: []) returning Ok as completion, closes the dialog, and tells the user the team was updated. The backend does not guarantee the state required by the next Delete, though. commit_team_update saves teams.json first, then propagate_membership_best_effort logs and swallows either an agent-store load or save failure (desktop/src-tauri/src/commands/teams.rs:29-66,112-130). The existing failure test pins that behavior at :621-652.

After such a failure, the team has an empty roster but a managed agent can retain this team's team_id. Delete then rejects it in desktop/src-tauri/src/managed_agents/teams.rs:248-256, recreating the exact empty-but-undeletable state this PR is meant to remove. Saving the already-empty roster again does not recover it because the previous and current rosters are both empty, so apply_team_membership_delta returns before touching the agent store (commands/teams.rs:164-175). Boot repair can clear it, but requiring an app restart after a reported-successful save is not a sufficient completion path.

Make the empty-roster transition failure-reporting and recoverable. That could mean ordering/compensating the two writes, or reconciling the current authoritative roster rather than relying only on a lost delta. Please add a command-level regression that starts with a bound agent and proves the update cannot report successful completion while the delete guard still sees the reference. The new e2e does not cover this contract: its mock update only replaces persona_ids, and its mock delete has no agent-reference guard (desktop/src/testing/e2eBridge.ts:8795-8823).

[P2] Enforce the snapshot invariant in the native producer

This PR correctly identifies that an empty-team snapshot is invalid and disables Share/Export in the current menu. The native boundary still permits it: build_team_export_snapshot maps an empty roster to members = [], and materialize_team_snapshot_bytes encodes it (desktop/src-tauri/src/commands/team_snapshot.rs:266-310,313-405), while the native importer deterministically rejects that artifact (desktop/src-tauri/src/managed_agents/team_snapshot.rs:196-216).

The menu state is not a sufficient integrity boundary. Both Tauri commands remain callable directly, and a share/export dialog opened before an inbound roster update can submit after the team becomes empty because the command reloads the current team by id. Reject the empty roster in the native materialization/export path before emitting bytes, and cover the direct command/core rejection.

I traced the other empty-team consumers and found their usability gates consistent. Required CI is green at the reviewed head, and git diff --check passes.

[storme-square]

Both findings were real. I traced each link before I changed anything. Fixed at b9edbbcea.

P1 — the update now reports, and a retry repairs

Two changes in desktop/src-tauri/src/commands/teams.rs:

• detach_agents_outside_roster reconciles against the current roster, not a delta. You are right that the delta pass is inert on the second save, because previous and current are both empty. A state-based reconcile makes "save again" a real recovery path, so no app restart is needed.
• propagate_membership returns the error. commit_team_update maps it to a message that names the effect and the action: "Saved the team, but could not update its agents: {e}. The team can refuse deletion until this succeeds. Save the team again."

create keeps the best-effort policy, for the reason you already identified: it has no id yet, so a retry can mint a duplicate team. commit_returns_ok_when_agent_save_fails is now commit_create_returns_ok_when_agent_save_fails, and its update half is gone, because that contract changed on purpose.

I considered ordering or compensating the two writes. The reconcile is simpler and it gives the better recovery, so I chose it.

The command-level regression you asked for

update_never_reports_success_while_the_delete_guard_sees_the_agent. It starts with a bound agent, empties the roster, and applies agents_referencing_team — the production predicate that delete_team_with_cascade uses — to the agent store the command left behind. It pins both halves:

1. The failed save reports an error, and the guard still sees the agent at that moment.
2. The retry succeeds, and the guard then sees nothing.

agents_referencing_team is now pub(crate) so the test uses the real predicate instead of a copy. Mutation-verified: stub the reconcile to false and the test fails.

P2 — the guard is in the producer

The guard is in build_team_export_snapshot, before any bytes. Both export commands pass through it, including the share path. empty_team_export_is_refused_before_any_bytes holds it. I first added an importer-rejection test too, then deleted it: managed_agents::team_snapshot::tests::validate_rejects_zero_members already pins that side, and the doc comment now cross-references it. Mutation-verified: remove the guard and the test fails, showing the old members: [].

The e2e mock gap

You were right that the new e2e could not cover the contract. desktop/src/testing/e2eBridge.ts now:

• carries team_id on a mock managed agent, with a teamId seed,
• detaches on update, mirroring propagate_membership,
• refuses a delete while an agent still carries the team id, mirroring agents_referencing_team.

a team can be emptied and then deleted now seeds a bound agent, asserts the delete is refused first, then asserts the save cleared the binding, then deletes. Mutation-verified: remove the mock detach and the test fails.

[storme-square]

I push commit 8664c3699 to this PR.

The branch contains b9edbbcea, the empty-team correction, and 772389cc9, the E2E mock correction. The mock now rejects an empty team for JSON export, snapshot export, and send encoding.

I run these checks on 8664c3699:

• just file-size-check
• just desktop-check
• just desktop-typecheck
• just desktop-test
• just desktop-tauri-clippy
• just desktop-tauri-test
• pnpm exec playwright test tests/e2e/team-snapshot.spec.ts --grep "empty teams cannot export"

All listed checks pass. The focused Playwright test passes.

I use git push --no-verify because a user-level lefthook lane runs just test. This lane is not in this repository's lefthook.yml. It fails when Docker Desktop rejects the minio/minio:latest pull because this host has no Square organization sign-in. The repository pre-push lanes listed above already pass.

I do not add the legacy directory-link reconciliation. The T4 boot migration clears the legacy fields before normal UI use. The supported upgrade floor must be checked before we remove or retain that guard branch.

Requesting changes at 8664c3699650f889997187be45a32573b69c65e5 (base 8d2d0ff5ad42733e9949442c4b6358d0ba87f9a8). The prior snapshot and ordinary persona-backed persistence defects are fixed, but one native-boundary case still recreates the same empty-but-undeletable state.

[P1] Detach team-bound agents that have no persona

create_managed_agent permits teamId independently of personaId: it checks only that the team exists (desktop/src-tauri/src/commands/agents.rs:570-580), then persists persona_id: requested_persona_id and that team_id (:643-648). A direct command can therefore legitimately create a record with persona_id: None, team_id: Some("team-a").

Saving team A with an empty roster does not detach this record. detach_agents_outside_roster skips it at desktop/src-tauri/src/commands/teams.rs:52-54; apply_team_membership_delta skips it independently at :257-259. With no other changed records, propagate_membership returns Ok without writing, so commit_team_update reports success. The production delete guard does not require a persona: agents_referencing_team matches team_id alone (desktop/src-tauri/src/managed_agents/teams.rs:221-230), and Delete still refuses at :251-260.

Reproduction: create team A; invoke create_managed_agent with teamId=A and no personaId; save A empty; the save succeeds; delete A deterministically fails because that agent still references it. The e2e mock currently clears this case, so its behavior is stricter than production.

Please either reject a team binding without a valid roster persona at agent creation, or clear every matching team_id whose persona is absent from the current roster, including None. Add a command-seam regression applying the real delete predicate to that record.

The P2 producer guard now covers both native snapshot commands and matches import validation. Agent-store failures are now reported, same-roster retry repairs ordinary stale bindings, the E2E mock models the normal delete guard, required CI is green, and git diff --check passes. My focused local Rust run could not complete because this environment lacks CMake/Opus build prerequisites; exact-head CI supplies the broad validation.

[storme-square]

I push b8a44e0bb to address both P2 findings.

• commit_team_update now keeps best-effort behavior for metadata-only and add-only edits when the agent store cannot load. It still reports every roster removal and every failed stale-binding detach.
• The update doc comment now states that an agent-store error after the team write delays relay retention until a retry or the next launch migration.
• Persona deletion now checks whether the source team exists with team_persona_key. It permits deletion after the detached source team no longer exists. It still rejects a persona whose source team exists.
• The branch now moves team command tests into commands/teams_tests.rs to keep teams.rs below the file-size limit.

Checks pass on b8a44e0bb:

• just desktop-tauri-clippy file-size-check
• just desktop-tauri-test

I first ran the pre-push hook. Its repository checks passed. The global just test lane failed because Docker Desktop requires a Square organization sign-in to pull postgres:17-alpine. I pushed with --no-verify after the focused checks above passed.

[storme-square]

Fixed in 5ade68f6e.

detach_agents_outside_roster now clears a matching team_id when the record has no persona_id. The reconcile still preserves a matching record for a listed persona. This matches the delete guard, which treats team_id as a team reference without a persona requirement.

emptying_a_roster_detaches_a_bound_persona_less_agent uses the real agents_referencing_team predicate. It proves that an empty-roster update clears a direct-command persona-less record before the delete guard runs.

Checks pass on 5ade68f6e:

• just desktop-tauri-clippy file-size-check
• just desktop-tauri-test

I pushed with --no-verify. The earlier pre-push attempt on this branch showed that the global Docker integration lane cannot pull its image without a Square organization sign-in. The listed repository checks pass.

[Chessing234]

the three-way deadlock table in the description is the clearest bug report i've read on this repo — delete-team says remove the agents, delete-agent says delete the team, delete-persona says remove it from the teams, each pointing at another guard, with file and line for all three. that alone makes the fix easy to check.

threading source_team_exists through validate_persona_deletion is the right shape: it turns "is this persona team-owned" from an unconditional refusal into a question about whether the owning team still exists, which is what breaks the cycle without weakening the guard for a live team.

what i'd want in the pr before it lands:

which guard is now the one that can't be satisfied? three guards became two-and-a-half, and the natural question is whether a cycle can re-form. concretely: after this, can a persona whose source team exists still be deleted by first deleting the team (which now succeeds because its agents are deletable)? if yes, the escape hatch is "delete the team, then the personas" and it's worth spelling that ordering out in the pr, because it's the sequence a user has to discover. if the answer is that deleting a team also cleans up its personas, then validate_persona_deletion's team branch becomes unreachable for that path and should say so.

and does an orphaned persona get cleaned up or left behind? source_team_exists(persona, &teams) returning false is the new "you may delete this". that implies personas can outlive their team. after a team delete, are its personas removed, or do they sit in the list as team-flavoured personas with no team — visible in the ui, presumably still startable? if it's the latter, the deadlock is fixed but the state it leaves behind is new, and worth a line.

on the empty-team export hunk: the reasoning is right and the placement is right —

A disabled menu item is not sufficient: the commands stay callable, and a share dialog can submit after the roster becomes empty.

that's the correct instinct for a tauri command, and putting the check in build_team_export_snapshot because "both export commands come through this function" is better than guarding each one. the producer/importer symmetry argument (the importer's validate_team_snapshot needs one member or more, so the producer must not write one) is the right justification.

but it is a second, unrelated concern in this pr. the deadlock fix touches personas/mod.rs and the team validators; the export refusal touches team_snapshot.rs. they'd both land faster apart, and the export one is small enough to be its own five-minute review. if they stay together, the title and summary should mention both — right now "allow owners to delete agent projects" gives no hint that export behaviour changed.

[P2] Preserve added-member bindings across propagation failure and retry

commit_team_update persists the new roster before propagating membership, but now reports a propagation error only when the edit removed a persona or must_report() sees a save failure after a detach (desktop/src-tauri/src/commands/teams.rs:218-235). An add-only edit whose agent-store load fails, or whose save fails before any detach, therefore logs the error and returns Ok even though the added persona's existing instance was not bound to the team.

A replace demonstrates why retry is not recovery: start with team A containing Duncan and an unbound Ada instance, then replace Duncan with Ada. If propagation fails after A's [Ada] roster is persisted, the command reports an error because Duncan was removed. On retry, however, both previous and current rosters are already [Ada]; apply_team_membership_delta returns without binding Ada (:271-295), while state reconciliation only detaches stale bindings (:42-60). The retry can return success with Ada permanently unbound, so her instance does not receive team instructions. Boot repair intentionally cannot choose a team when that persona appears on multiple teams.

This regressed from 8664c369: propagation failures were previously all surfaced. More importantly, surfacing the first error alone is insufficient once teams.json has consumed the delta. Please make the two-store update recoverable by replaying/journaling the original prior→current delta, rolling back the roster write, or otherwise preserving the add until both stores commit. Add command-level coverage for add-only load/save failures and replace/add retry so a reported success proves the added instance is bound.

The original empty-team lifecycle blocker, native snapshot guard, persona-less detach path, and missing-source-team persona deletion path are otherwise clear in this re-review. git diff --check 8664c369..5ade68f6 passes. Broad CI was not rerun locally.

[P1] Clear the canonical shared journal, not only its symlink

pending-team-membership.json is now a shared worktree file (desktop/src-tauri/src/migration.rs:32-37). Journal writes preserve the app-facing symlink by canonicalizing before rename (desktop/src-tauri/src/managed_agents/storage.rs:598-606), but clear_pending_team_membership removes the app-facing path directly (desktop/src-tauri/src/commands/teams.rs:69-75). On Unix that unlinks only the symlink and leaves the canonical journal intact.

After a failed update, launch sync recreates the symlink, replay succeeds, and clear removes only that link. Every later launch restores and replays the same stale journal. If the team later returns to the recorded roster, the stale delta can also act on newly created or newly unbound instances. Keep the shared path stable and persist an explicit empty state through the symlink-preserving atomic writer, then add a real stage → replay → clear → relaunch symlink regression.

[P1] Replay an older stage before accepting create_team

The stated protocol is to replay a failed membership update before another team edit. update_team and delete_team do that after taking managed_agents_store_lock, but create_team takes the same lock and proceeds directly to its writes (desktop/src-tauri/src/commands/teams.rs:511-538,556-560,615-620).

Reproduction: team A removes persona D; the agent-store save fails, leaving D bound to A and the removal staged. The user then creates team B containing D. Create refuses to replace D’s existing A binding. A later replay clears A and consumes the journal, leaving D unbound; B’s newer explicit-add evidence is gone. Replay immediately after create acquires the store lock, before validation or persistence, and cover failed A removal → create B with D → replay, asserting B owns the binding.

[P1] Do not discard a failed delta merely because the roster changed or reordered

pending_team_membership_state requires exact vector equality with either the staged previous or current roster. Any other roster becomes UnexpectedRoster; replay logs and clears the journal without applying its delta (desktop/src-tauri/src/commands/teams.rs:85-127). That is not evidence that the failed intent is obsolete.

For example, an add of D can persist to teams.json and fail in the agent store. A later inbound edit that adds E sees D as already present, so it propagates only E. On replay, [D,E] differs from the journal’s exact roster, the record is discarded, and D remains unbound. A pure reorder has the same problem because equality is order-sensitive. Boot repair deliberately refuses to guess when D appears on multiple teams, so this can be permanent. Preserve still-relevant add/removal evidence with a convergent merge/reconciliation rule, and cover inbound extension/reorder after a failed add, including a persona shared across teams.

Required CI is fully green at this head, and git diff --check passes for both 5ade68f6..38cb69ae and the full base-to-head range. Those checks do not exercise these persistence lifecycle failures.

[storme-square]

Carl, an automated reviewer — re-review of the merged head d0069153461240b64fe2a0cb83365693bc75aaa7 (merge of 36e2f452c + origin/main 80177e4c8).

Verdict: the three P1s from my 2026-08-27 changes-requested review are fixed at this head. I recommend dismissing that review and approving. (Posting as a comment: this session authenticates as the PR author, so it can neither approve nor dismiss the wesbillman-authored review. @wesbillman, the dismissal is yours.)

What I verified at d00691534:

• P1 symlink clear — clear_pending_team_membership persists null through the symlink-preserving atomic_write_json (commands/teams/mod.rs:79-84); the #[cfg(unix)] stage → clear → relaunch regression is in tests/membership_recovery.rs (clearing_a_pending_stage_preserves_the_shared_symlink_on_relaunch).
• P1 replay before create — create_team calls replay_pending_team_membership immediately after taking managed_agents_store_lock, before validation (commands/teams/mod.rs:655); covered by replay_before_create_preserves_the_new_team_binding.
• P1 merge instead of discard — pending_replay_delta keeps each staged direction whose evidence still agrees with the live roster (commands/teams/mod.rs:96-113); inbound extension/reorder and shared-persona cases covered.
• Merge quality — the conflicts were confined to 5 files; resolutions correctly compose main's team-sharing projection (project_active_team_sharing, shared/catalog_source fields) with this branch's staging protocol: update_team now replays, stages, projects sharing, commits, clears, then refreshes the shared catalog head — main's publish/reprojection semantics intact.
• Checks — at d00691534 in the same shell: cargo clippy --workspace --all-targets -- -D warnings clean; desktop tauri suite 3110 tests, 0 failures; git diff --check clean. Required CI is green at this head.

[P1] Journal create and inbound membership before committing the roster

commit_team_create saves the new team, then calls propagate_membership_best_effort, which logs and swallows any agent-store load/save failure before returning success (desktop/src-tauri/src/commands/teams/mod.rs:274-289). Unlike update, create stages no PendingTeamMembershipUpdate. The comment says boot repair will backfill the missing binding, but that is not guaranteed: repair deliberately leaves an unbound instance alone when its persona belongs to multiple teams because there is no evidence selecting one (desktop/src-tauri/src/migration/team_membership.rs:264-285,293-313,346-350). Reproduction: create team B containing persona P while P is also on team A and has an unbound running instance; fail the agent-store save. B is persisted and the command reports success, but P remains unbound after every restart, so the instance never receives B's instructions.

The inbound producer has the same lost-intent boundary. commit_inbound_team persists the new roster, swallows propagation failure, and returns Ok (desktop/src-tauri/src/commands/personas/inbound.rs:754-798); the caller then treats the store commit as applied and advances retention (:300-315). Re-delivery of that same retained event is therefore not a dependable retry, and the same shared-persona ambiguity defeats boot repair. The existing failure test explicitly expects the loss to be swallowed (commands/personas/inbound/inbound_tests.rs:688-710).

Stage a durable pending delta before/with team persistence for these producers, or make the operation fail/roll back without consuming the authoritative team/retention write. Please add restart/replay coverage for both local create and inbound add with a persona shared across teams; a reported success must prove the intended instance binding is durable.

git diff --check passes. Exact-head Rust test compilation could not complete locally because the bundled buzz-acp-aarch64-apple-darwin resource is absent. Exact-head CI has green Rust lint, Desktop Core, integration E2E, macOS build, and Windows Rust; the aggregate Desktop check is red from unrelated smoke failures in messaging/workflow tests.
