+- **Documentation accountability**: derive the official module inventory from
+  signed module manifests and the marketplace registry, then fail local
+  pre-commit and PR documentation validation when core catalogues, generated
+  command records, or core/modules ownership statements drift. The repaired

 - Module system is **production-ready** (introduced in `v0.27`) and is the default command-loading path.

+- Canonical bundle-deep documentation is owned by the [modules documentation site](https://modules.specfact.io/).

+# Change Validation: cli-val-05-ci-integration
+
+- **Validated on:** 2026-07-10 Europe/Berlin
+- **Workflow:** implementation-readiness review and strict OpenSpec validation
+- **Strict command:** `hatch run openspec validate cli-val-05-ci-integration --strict`
+- **Result:** PASS (0 issues)
+
+## Scope Summary
+
+- **Extended capability:** `documentation-accountability`
+- **Source issue:** [#643](https://github.com/nold-ai/specfact-cli/issues/643),
+  open and unblocked under parent [#375](https://github.com/nold-ai/specfact-cli/issues/375)
+- **Outcome:** derive official module package and grouped-command ownership from
+  the paired modules repository; fail closed when core catalogues, generated
+  command metadata, or ownership statements drift.
+
+## Breaking-Change Analysis
+
+This is a validation and documentation hardening change. It adds no public CLI
+command, removes no supported interface, and leaves the requirements profile
+explicit-opt-in behavior unchanged. The only operational change is deliberate:
+contributors and PRs must provide a valid modules checkout for documentation
+validation rather than silently accepting incomplete documentation evidence.
+
+## Dependency and Ownership Review
+
+- `specfact-cli-modules` manifests and `registry/index.json` are the source of
+  truth for official package IDs and grouped command roots.
+- Core owns the generated command overview, command contract, catalogue pages,
+  and the fail-closed validation integration.
+- Modules own package manifests, marketplace registry entries, package runtime,
+  and deep module workflow documentation.
+- The change order now lists `cli-val-05` with issue #643 and its validation
+  predecessors.
+
+## Internal Wiki Status
+
+The sibling internal checkout already has an uncommitted modification to
+`wiki/sources/cli-val-05-ci-integration.md` outside this worktree. It was not
+overwritten. Before merge, its owner must reconcile this scope update and run
+`wiki_rebuild_graph.py` from the internal repository root; this preserves that
+checkout's existing work while keeping the public OpenSpec source authoritative.
+
+## Validation Outcome
+
+- Required change artifacts are present and parseable.
+- Strict OpenSpec validation passes.
+- The change records source authority, fail-closed local/PR enforcement,
+  catalogue completeness, generated-command ownership, and architecture
+  handoff consistency.

+
+Result: passed after remediation.
+
+Summary:
+
+- 20 focused tests passed. They prove catalogue omissions, missing generated
+  command records, and contradictory ownership claims fail for official module
+  roots, in addition to requirements inventory, missing-source coverage,
+  explicit-path failure, generated ownership metadata, and removed aliases.
+- `smart-test-unit` and `smart-test-folder` completed with no changed paths to
+  select; `smart-test-full` ran the full suite.
+- The full suite passed: 2,826 tests passed, 9 skipped, with 64% line
+  coverage against the configured and CI-enforced 50% `fail_under` gate.
+  The repository separately enforces contract coverage (80%) and behavioral
+  coverage (90%); this line-coverage result does not claim an 80% line target.
+- The first full run exposed a stale category-group expectation that omitted
+  the already shipped `requirements` root; the test was corrected and the full
+  suite was rerun successfully.
+- Type checking completed with 0 errors (existing repository warnings remain);
+  full lint, contract tests, workflow/YAML validation, Bandit, and strict
+  OpenSpec validation passed.
+

+
+Command:
+
+```bash
+bash scripts/pre-commit-quality-checks.sh
+```
+
+Result: passed. The staged hook ran the same fail-closed documentation gate,
+command checks, lint, workflow checks, and code-review wrapper used before a
+commit.
+
+- The review report has **0 errors** and `PASS_WITH_ADVISORY`. Its 12 warnings
+  are pre-existing findings on unchanged lines: the checker’s existing
+  catalogue-loop depth, legacy unknown-type findings, and pre-existing public
+  function decorator gaps in the command-overview generator. They are outside
+  this review-fix scope; no warning was introduced by these changes.
+- All new-checker and changed-test findings were remediated: complexity,
+  nesting, output handling, type narrowing, design-by-contract coverage, and
+  duplicate test shape.
+- 13 residual warnings are pre-existing static-analysis limitations in the
+  two legacy command-artifact scripts (`check-command-contract.py` and
+  `generate-command-overview.py`) plus Typer's dynamic `commands` attribute in
+  the existing category-group tests. They are non-blocking, produce no
+  type-check errors, and are outside this accountability scope; the report is
+  retained at `.specfact/code-review.json` for follow-up cleanup.

 - Treat Semgrep and Bandit as independent evidence: they run outside `specfact code review` and upload raw artifacts.
 - Keep Windows smoke scheduled/manual at first; make macOS PR-blocking for changed runtime/package paths.
 - Start mutation testing as scheduled advisory evidence, with explicit critical-module targeting and an uploaded baseline report.
+- Treat the official modules repository as the authority for official package ids, root commands, and canonical deep-documentation ownership. Core must fail closed when that source cannot be resolved for a documentation-accountability run.
+- Keep the accountability mapping explicit and reviewable: it names the core catalogue and ownership pages that must represent every official package, while the checker derives the required package and root-command set from the modules manifests and registry instead of duplicating it in Python.
+- Run the same documentation-accountability command from pre-commit and the PR workflow. Generated command freshness, command syntax, frontmatter shape, and cross-site HTTP reachability remain complementary checks; none is a substitute for catalogue completeness and ownership consistency.
 
 ## Risks / Trade-offs
 
 - CI time increases. Mitigation: path-gate package matrix and macOS smoke; keep Windows scheduled until stable.
 - Wheel runtime checks may expose module checkout assumptions. Mitigation: use existing paired-branch module checkout logic and emit per-launcher logs.
 - Coverage enforcement can block useful work. Mitigation: use governed exception/profile work for temporary waivers, not silent advisory workflow behavior.
+- A local contributor may not have the sibling modules checkout. Mitigation: resolve `SPECFACT_MODULES_REPO` first, then the documented sibling path; fail with an actionable setup message rather than silently skipping the accountability proof.

+## ADDED Requirements
+
+### Requirement: Official module documentation accountability SHALL derive from source authority
+
+The documentation-accountability contract SHALL derive the set of official
+module package ids and grouped command roots from the checked-out
+`specfact-cli-modules` manifests and marketplace registry. It SHALL reject a
+missing, unreadable, or internally inconsistent modules source rather than
+falling back to a hard-coded core package list.
+
+#### Scenario: Requirements module is an official source record
+
+- **GIVEN** the modules source contains the official
+  `nold-ai/specfact-requirements` manifest and registry entry
+- **WHEN** the documentation-accountability contract builds its inventory
+- **THEN** the inventory contains package id
+  `nold-ai/specfact-requirements` and root command `requirements`
+- **AND** the generated command overview and runtime command contract include
+  that package and root.
+
+#### Scenario: Modules source is unavailable or inconsistent
+
+- **GIVEN** `SPECFACT_MODULES_REPO` and the documented sibling checkout cannot
+  provide a valid official-module manifest and registry source
+- **WHEN** the documentation-accountability contract runs locally or in CI
+- **THEN** it exits non-zero with an actionable source-resolution error
+- **AND** it does not silently skip validation or reuse a stale hard-coded list.
+
+### Requirement: Core catalogues SHALL cover every official module
+
+The documentation-accountability contract SHALL require every designated core
+package catalogue, command reference, install overview, and repository-layout
+page to represent every official module package and its grouped command root
+where that page describes command topology. The contract SHALL report the
+missing package, expected root, file, and location.
+
+#### Scenario: A catalogue omits a shipped official module
+
+- **GIVEN** a designated core catalogue lists other official packages but omits
+  `nold-ai/specfact-requirements`
+- **WHEN** the documentation-accountability contract runs
+- **THEN** it exits non-zero
+- **AND** identifies the catalogue file and omitted package.
+
+### Requirement: Core and modules documentation ownership SHALL be consistent
+
+Core overview and architecture pages SHALL accurately distinguish permanent
+core runtime/lifecycle ownership from module-owned grouped command and deep
+workflow documentation. They SHALL not classify an installed official grouped
+command as a removed or non-canonical core surface, and required handoffs SHALL
+target the canonical modules documentation path.
+
+#### Scenario: Core architecture contradicts an installed module command
+
+- **GIVEN** a core architecture or ownership page states that an official
+  grouped command such as `specfact requirements ...` is not canonical
+- **WHEN** the documentation-accountability contract runs
+- **THEN** it exits non-zero and identifies the conflicting ownership claim.
+
+### Requirement: Documentation accountability SHALL block locally and in PR CI
+
+The same documentation-accountability command SHALL run from the always-run
+local pre-commit path and from a required pull-request workflow job whenever
+documentation, command-contract, module-discovery, module manifest, or
+workflow inputs change.
+
+#### Scenario: Accountability failure prevents delivery
+
+- **GIVEN** a staged or pull-request change leaves a catalogue, generated
+  command artifact, or ownership handoff inconsistent with the official-module
+  inventory
+- **WHEN** pre-commit or PR CI runs
+- **THEN** the relevant gate exits non-zero
+- **AND** the pull request cannot satisfy its required documentation check.
