Roadmap the quality-gate integrity audit domain

[leynos]

Summary

This branch roadmaps a sixth Auditor domain, Quality-Gate Integrity,
distilled from the 2026 estate rollouts (Whitaker lint across 30+
repositories, the CodeScene coverage retrofit, the Dependabot auto-merge
and cooldown rollout, and scheduled mutation testing). Every check
corresponds to a defect class observed in production repositories:
lint gates that could not fail (soft-skip Makefiles, environment-variable
no-ops, stale git-revision installs), test suites whose doctests had
never executed, coverage pipelines that never reached their consumer
(uploads from pull requests that the provider rejects, missing
main-branch upload workflows, summary-only reports, secrets present in
only one of GitHub's two secret stores, ratchet baselines scoped to the
wrong branch), Dependabot auto-merge jammed by stale third-party checks
or deadlocked by lockfile-wide audits, workflows failing at load time on
every trigger, manifest pins that made security alerts unactionable, and
absent mutation testing.

Review feedback extends the branch with two further domains:
Licensing Integrity (LC-001 to LC-003 — LICENSE presence,
copyright currency against the latest commit, and declared-licence
consistency between manifests, the README, and the governing LICENSE
under a nearest-ancestor rule) and Toolchain Baseline (PY-001 to
PY-010 and RT-001 to RT-011 — the leynos/agent-template-python and
leynos/agent-template-rust templates encoded as auditable floors for
formatting, linting, documentation coverage, Python version-floor
consistency, typechecking, and test tooling). Python applicability is
content-driven, so incidental use — helper scripts, Python-implemented
GitHub Actions, Ansible modules — brings a repository into scope; the
"match or exceed" rules compare against template baselines vendored at
a pinned tag rather than fetched at audit time.

The design document gains the domain definitions, forty-two new
catalogue entries (QG, CV, AM, DP, DB, MT, LC, PY, and RT families) in
the Auditor check catalog, and sensors-and-actuators specifications
(Sections 3.1.1 to 3.1.3) mapping each check onto the existing lint
rule package format (sensor + parameters + mutation), including where
actuators degrade to tracking issues when automation lacks the
necessary material (for example, secret values or licence identity).
The roadmap gains Sections 4.2 and 4.3 sequencing delivery of the rule
packages and Auditor sweeps with fixture-based acceptance criteria.

Review walkthrough

• Start with the domain definition and
  Table 3 additions in docs/concordat-design.md
  (Section 3.1 and the check catalog).
• Then the sensors-and-actuators specifications in Sections 3.1.1
  (quality-gate integrity), 3.1.2 (licensing integrity), and 3.1.3
  (toolchain baseline) of the same document — one subsection per defect
  family, each opening with the motivation for it.
• Finish with
  Sections 4.2 and 4.3 of docs/roadmap.md,
  which sequence the rule-package deliveries.

Validation

• make check-fmt, make lint, make typecheck, make test: all
  pass (246 tests passed, 1 skipped).
• make markdownlint: 0 errors.
• make nixie: all diagrams validated.
• make fmt applied; unrelated formatting churn in untouched documents
  reverted to keep the diff scoped.

Summary by Sourcery

Roadmap three new Auditor integrity domains and define the rule, remediation, safety, and validation contracts needed to deliver them.

New Features:

• Define Quality-Gate Integrity as a new Auditor domain covering lint binding, test completeness, coverage delivery, Dependabot governance, workflow health, dependency actionability, and mutation-testing coverage.
• Add Licensing Integrity and Toolchain Baseline domains with catalogue checks for licence consistency and Python/Rust template-aligned tooling standards.
• Specify snapshot-based GitHub API sensors and actuators with credential isolation, idempotency, concurrency control, reconciliation, shutdown handling, and observability requirements.
• Roadmap delivery of the new rule packages, Auditor sweeps, fixtures, and property/state-machine acceptance tests.

Bug Fixes:

• Clarify OpenTofu drift detection and backend write-access validation semantics.
• Require reusable workflow references to use immutable commit SHAs or explicitly verified immutable tags instead of branches or unverified tags.

Enhancements:

• Expand the lint rule contract to support pure GitHub-state evaluation and authenticated remediation side effects.
• Strengthen typos rollout tests with malformed-input coverage, spelling-policy integration checks, and deterministic list normalization.

Documentation:

• Document the new audit domains, forty-two catalogue checks, sensor and actuator contracts, API safety model, observability requirements, and staged implementation roadmap.

Tests:

• Add validation coverage for dictionary schema and field types, spelling exceptions and detections, duplicate sorting, and absent-key defaults.

Chores:

• Update spelling configuration to allow the mold linker name.

• Add 42 Auditor catalogue entries for quality gates, coverage, Dependabot, dependency pins, mutation testing, licensing, and Python and Rust tooling.
• Specify GitHub API sensor and actuator behaviour, including scoped identity, immutable workflow pins, concurrency, leases, retries, reconciliation, shutdown handling, recovery, failure alerts, and observability.
• Separate live rule acquire API access from read-only rule run queries over injected snapshots.
• Add roadmap acceptance criteria for atomic actuator concurrency and deterministic model-based state-machine testing.
• Clarify OpenTofu drift-plan exits, remote-state encryption, bucket preflight checks, workflow reference pinning, and artefact CLI exit codes.
• Extend typos configuration and tests. Group invalid dictionary fixtures in the InvalidDictionaryCase dataclass.
• Record successful formatting, linting, typechecking, tests, Markdown validation, and diagram validation.

Testing

• Run the focused typos rollout tests.
• Run the full lint and test checks.
• Validate Markdown and diagrams.

🚥 Pre-merge checks | ✅ 18 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Developer Documentation	⚠️ Warning	The PR adds immutable-SHA/verified-tag rules, but Section 2.4 still permits any tagged workflow; the new typos integration test also lacks its uv/typos requirement in the developers' guide.	Update Section 2.4 to require an immutable SHA or verified immutable tag. Document the pinned typos test tool and uv setup in docs/developers-guide.md.
Title check	⚠️ Warning	The title matches the changes, but it omits the roadmap item number required for the referenced Sections 4.2 and 4.3.	Add the applicable roadmap item number to the title, such as “(4.2/4.3) Roadmap the quality-gate integrity audit domain”.

Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Testing (Overall)	✅ Passed	The PR changes only documentation, spelling configuration, and tests; the new tests assert validation, deterministic parsing, defaults, and real typos outcomes including the new mold policy.
User-Facing Documentation	✅ Passed	The PR diff adds roadmap/design specifications, spelling-policy tests/configuration, and dependency floors; it adds no shipped user-facing behaviour, and the existing CLI is already documented in d...
Module-Level Documentation	✅ Passed	The only changed Python module retains the clear docstring “Tests for the repository spelling-policy scripts.” Other changed files are documentation or configuration.
Testing (Unit And Behavioural)	✅ Passed	Accept the testing change: cover dictionary errors, sorting, defaults, and the configured typos CLI boundary; treat the remaining documentation-only specifications as non-runtime changes.
Testing (Property / Proof)	✅ Passed	Pass this check: the changed design explicitly requires Hypothesis property tests, a RuleBasedStateMachine, reference-model invariants, shrinking, and oracle checks for introduced interleavings and...
Testing (Compile-Time / Ui)	✅ Passed	Pass: the diff changes Markdown, TOML, and Python tests only; it adds no Rust/TypeScript compile-time behaviour, and the typos CLI test uses focused return-code and diagnostic assertions.
Unit Architecture	✅ Passed	Accept this change: the diff changes only docs, spelling configuration, and tests; the design explicitly isolates fallible acquisition, pure snapshot queries, injected test seams, and named side-ef...
Domain Architecture	✅ Passed	Keep the boundary: the PR changes no production domain modules, and its new rule contract makes sensors pure over snapshots while isolating API acquisition and actuator effects.
Observability	✅ Passed	Keep the change as documentation, tests, and spelling configuration: no runtime behaviour changed, and Section 3.2.2 specifies logs, bounded metrics, traces, alerts, and secret exclusion.
Security And Privacy	✅ Passed	Pass the check: the diff changes documentation, spelling tests/configuration, and dependency locks; scans found no credential literals, while new API contracts require least privilege and exclude s...
Performance And Resource Use	✅ Passed	The diff adds no production runtime path; it adds three fixed-size one-fixture typos subprocess tests, while the API design specifies bounded retries and low-cardinality metrics.
Concurrency And State	✅ Passed	Pass this check: the PR adds no executable shared-state or async implementation; its new API-actuator design defines leases, fencing, retries, shutdown, partial failure, and deterministic state-mac...
Architectural Complexity And Maintainability	✅ Passed	The diff adds no production architecture or dependencies. The documented API seam has five immediate consumers, explicit pure/acquisition boundaries, and state-machine invariants with roadmap tests.
Rust Compiler Lint Integrity	✅ Passed	The merge-base diff changes only Markdown, Python, and TOML files. Neither the base nor the tip contains tracked Rust or Cargo files, so this Rust-specific check is inapplicable.
Description check	✅ Passed	The description directly explains the new audit domains, catalogue entries, API contracts, roadmap work, and validation results.

Make workflow pinning unambiguous.
Line 2795 permits consumers to pin @v1, but this range rejects mutable references. A major-version tag can move, so the same reference is both accepted and rejected. Require an immutable commit SHA or an explicitly verified immutable tag mechanism, and apply the same rule in docs/roadmap.md.
