fix: preserve release identity and scope owned skill updates

[devantler]

🤖 Generated by the Agentic Engineer

Why

Release preparation can report success from ambiguous or unrelated evidence, publish misleading source notes, or write outside its checkout.

What

Keep release checks and generated notes bound to one complete history, the intended checkout and committed sources. Preserve original files whenever declarations or destinations are ambiguous, and let maintainers synchronize the portfolio-owned skills on their own. This also completes #479, #480, #481, #482 and #487.

Fixes #478

📝 Walkthrough

Walkthrough

The changelog script now validates Git history, committed skill metadata, manifest versions, and write paths. The version-bump script rejects ambiguous JSON declarations before processing manifests. New and updated tests cover these boundaries, and the validation instructions include the new integration test.

Priority: ⬇️ Low

Severity of issue fixed: Low

Merge Risk: 🟡 Moderate · up to a0722

Resolve the write-path race before relying on checkout-confined release writes, and make the documented boundary test runnable without an undeclared checksum dependency.

Security Architecture Review

Security architecture risk: 🔵 Low · up to a0722

The changes strengthen release validation and reject ambiguous inputs before publication files are changed. A pre-existing filesystem race remains: an actor able to replace checkout directories during a release write could redirect that write. The inspected changes do not introduce broader privileges or worsen that exposure.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The residual attack requires authority to replace checkout ancestors concurrently with the release process. Its maximum filesystem reach is outside the checkout to destinations reachable through those replacements and writable by the process. The evidence does not establish remote reachability, cross-tenant access, or additional privilege gained through this PR.

Security Findings and Attack Paths

• observed — The retained path-traversal finding describes an ancestor-replacement race: after directory validation, a concurrent actor can substitute a symlink, allowing later path-based staging or replacement to resolve outside the checkout. Base/head inspection found this exposure already existed in the unchanged batch writer. The PR adds static parent checks and does not introduce or worsen this condition, so it is recorded as a residual security fact rather than an active PR architecture concern.

Trust Boundaries and Controls

• observed — The strengthened controls bind Git operations to the caller's checkout context, comparisons to unambiguous complete history, notes to regular committed provenance, and versions to unambiguous manifest declarations. Static parent and destination guards, cooperative locking, and pre-replacement comparisons mitigate ordinary invalid inputs and supported-writer conflicts, but do not defeat concurrent ancestor substitution.

Resilience and Maintainability Implications

• observed — Both publication writers validate complete plans before invoking the shared replacement helper. This contains validation failures before publication changes and centralizes conflict handling. The remaining concurrency and interruption limitations belong to that shared helper and were not widened by the fixture-local test fanout.

Hardening Proposals

• proposed — If untrusted concurrent checkout mutation is within the release threat model, consider directory-handle-relative, no-follow filesystem operations or an isolated checkout that untrusted actors cannot mutate. Add race and interruption-recovery tests for the shared writer; repeated path checks alone would not establish race-free confinement.

• CodeRabbit: authenticated same-PR included-review refusal, event 2026-10-04T20:41:16Z, observed 2026-10-04T20:58:01Z. This PR remains covered by its ongoing included-review limit until 2026-10-04T21:16:16Z; the newer head does not reset the limit.

• Cursor Bugbot: authenticated user/team usage limit, event 2026-10-04T12:21:20Z, freshly observed 2026-10-04T20:58:01Z. User/team-scoped; no recovery time supplied; increasing spend is not authorized.

Two independent read-only reviews examined the final source and workflow. Release history remains complete and uniquely joined, both changelog modes ignore inherited Git selectors, surviving and removed skill provenance comes from regular committed objects, and ambiguous decoded manifest declarations refuse before writing. The new filesystem anchor starts from the inherited checkout directory, opens each ancestor without accepting a link, and compares directory identity before and after leaf operations. Relative staging operands retain caller identity. Moved-checkout cleanup refuses before deleting retained originals. Ordinary rollback, concurrent edit retention and shared writer serialization still work.

Independent actual races at root/plugin ancestor replacement and destination-directory-link replacement left external files unchanged. Both additional audit findings were reproduced before repair and now pass: caller staging bytes are selected correctly, and a root moved during backup retains its original. The 40 release cases, existing 53/17 changelog cases, shared generated-write safety suite and 36 version-bump cases pass; ShellCheck, Go vet, Linux compilation and manifest validation pass.

The opt-in scope preserves scheduled/all behavior and refuses unsupported observations before update. Actual pinned splitter and unchanged edit guard accept the identical canonical programmed branch for both scopes, while a wrong principal remains refused. All nine resolver controls and actionlint pass. Required CI now explicitly runs the new root suites. The earlier CodeRabbit findings are fixed with disclosed replies and resolved threads; no remaining actionable finding was found.

Verdict: no P0/P1 findings

Tried and evaluated at d324854: actual release preparation in independent Git repositories retains the intended caller under foreign Git selectors, prints committed upstream provenance despite altered/missing/linked working metadata, and refuses ambiguous manifests and histories without changing publication bytes. Normal release writing still produces the expected visible entry.

An actual ancestor swap at the rename boundary reproduced an external write before repair. The repaired command refuses successful publication and leaves external histories unchanged. Additional user-path checks preserve caller-relative staging identity, retain recovery originals after a checkout move, restore ordinary failed batches, and preserve conflicting edits with their backup. Final independent review reran root/plugin ancestor and destination-link races successfully.

The scope resolver's actual command preserves full-catalogue defaults, selects only the owned agentic skill directory on opt-in, and refuses unknown scope/event observations. Running the actual pinned splitter and unchanged edit guard confirms both scopes preserve the same programmed branch identity. The live scoped updater and generated skill PRs will be exercised immediately after merge; #487 remains open until that readback completes.
