Purpose

Define the LineageWeave-owned immutable-release caller boundary without duplicating the organization-owned credentialed SBOM/attestation policy. ADR 0361 remains Proposed; this PR is a Draft contract, not release-ready evidence.

Canonical-owner convergence

The former .github#1782 circular handoff prerequisite is resolved by merged .github#1791. The reviewed immutable owner pin is:

ContextualWisdomLab/.github/.github/workflows/exact-artifact-sbom-attestation.yml@bd866a21cca2a7e709f0b7a88150c310a9d98239

At that owner commit, source-identity.json excludes the post-upload GitHub Actions artifact digest while the reusable retains artifact ID/name/digest as an outer receipt and independently verifies it before download and again inside the credentialed signer boundary. LineageWeave consumes that exact released owner surface; it does not copy the verifier or pin mutable .github/main.

Review 5109457355 recorded the stale-owner finding on predecessor 9dfb79da481e37fe10e86e279f50b48179770dd1. RED contract 29a443c1a47232719325f8ed41cd3e17a7ed1ccb pinned .github#1791 plus the immutable owner SHA. Superseded RED runs were cancelled by subsequent pushes, so hosted RED is not claimed.

Release-race repair

CodeRabbit identified valid CWE-367/contract weaknesses: final settings reads were not themselves atomic publication controls; exact draft/asset identity needed final rebinding; tag validation could race retargeting; abort cleanup could delete a later-retargeted ref; and the docs test did not bind procedure ordering.

The Proposed contract now requires one exclusively serialized trusted release writer, a reviewed protected candidate release-tag namespace, and repository immutable-release admission with both enabled: true and enforced_by_owner: true. Exact Release ID, draft: true, exact tag_name, prerelease: false, complete sealed asset names/digests, recorded annotated tag object, peeled target type commit, and exact protected source SHA are revalidated immediately before publish. Post-publication verification requires immutable: true. Abort cleanup may remove a candidate ref only as compare-and-delete under the same trusted-writer/protected-namespace serialization; otherwise the version is quarantined.

The contract explicitly does not invent a GitHub compare-and-publish REST primitive. Owner-enforced immutability, protected tag namespace and trusted-writer serialization are mandatory configuration locks for the interval GitHub does not expose as one consumer-controlled atomic API call.

RED 099c28976e26cb27a86feaf5799d13b3c134d402 introduced structured publication-step assertions. ADR repair is c5d4a0db97e849979b883f7f530563c3dadf0b0c, corrected operator contract is a51ed489b4e5d3b32d9cc6f1051609738d249512, and doctoring/traceability is d0adba9b24adf349a071ee6c67640da32af841bc. 655ad58efa83f0e350f11cc7f141fdaf8e75baed then sliced the abort procedure itself. CodeRabbit correctly found that the cleanup controls inside that slice were still presence-only. Final test repair 084649ecc8542fcb54c81d6f05b27845415e0ed6 compares marker indexes and enforces ownership proof → compare-and-delete → trusted release writer → protected namespace/tag namespace → recorded tag-object SHA → serialization → quarantine, plus do not delete and post-cleanup re-resolve/absent. Intervening non-force commit 350152984fcb162c88188f1036da818362670ecd only normalizes wrapped whitespace when slicing numbered documentation steps, preserving those ordered contract assertions rather than weakening them. The review thread was reopened for the follow-up and resolved only after the stronger contract landed.

Remaining prerequisites

Exact live boundary

  • protected base: main@b0e94aa2a6f7a943f96dc5c4f2fdecd0021978a1
  • exact current head: 350152984fcb162c88188f1036da818362670ecd
  • PR: open / Draft / mechanically mergeable
  • exact-head Tests 33852307076, Security 33852307070, SAST 33852307177: queued; exact-head GREEN is not claimed
  • qualifying independent APPROVE: none
  • current inline review threads were resolved after their valid findings were repaired; no predecessor review/check evidence transfers to this head

Do not mark Ready, self-approve, bypass, publish, accept ADR 0361, or transfer predecessor workflow evidence.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 9dfb7

The proposed release boundary can still publish or delete against state that changed after verification, and its tests may not detect regressions in those controls. Although this PR does not activate a release workflow, the contract should be corrected before it becomes the implementation basis.

@coderabbitai review

Please review the exact current Draft head. Treat ADR 0358 as Proposed and verify especially the owner boundary, immutable release/rollback semantics, authoritative reference claims, and whether any wording could imply release delivery before .github#1782 and #911 are complete.

@seonghobae I reviewed 0eea51577d8b2e90c93937d14b89bbde0fe7bf84.

I found one issue.

  • Immutable publication is not enforceable. docs/release.md Line 55 and ADR 0358 Line 70 require a non-draft, non-prerelease GitHub Release. Those properties do not prevent an authorized actor from later editing or deleting the release, assets, or tag. The text prohibits those actions, but it does not require the GitHub immutable-releases control to be enabled or verify that it is enabled before publication. Add an admission condition that enables and verifies GitHub immutable releases before publication. Make failure of that condition RED. This makes the stated rollback rule enforceable: publish a corrected version, but do not mutate historical release evidence.

The remaining reviewed areas are consistent with the Draft scope:

  • ADR 0358 remains Proposed.
  • LineageWeave#911 and ContextualWisdomLab/.github#1782 remain open prerequisites.
  • The documents do not claim a delivered release workflow, GitHub Release, or release readiness.
  • The product-to-organization owner boundary is explicit. LineageWeave does not vendor or weaken the central verifier.
  • The release sequence requires an exact protected main SHA, an exact reusable-workflow SHA, terminal-success gates, unprivileged build work, canonical verification before publication, and new artifacts for rollback.
  • The documents correctly reject predecessor-head evidence transfer.
  • The reference note limits CycloneDX, SLSA, GitHub, and RFC 8259 claims to their stated scope. It does not claim a SLSA level or assign repository-specific JSON validation to RFC 8259.

docs/adr/0361-immutable-release-supply-chain-boundary.md lines 139-143 and

version; retain the existing absent-state rechecks and exact-candidate deletion
requirements.

retargeting between validation and publish; update

admission check and publication. Update
docs/adr/0361-immutable-release-supply-chain-boundary.md lines 115-125 and

before publishing: Release ID, draft:true, tag_name, prerelease:false, and the
complete asset set with digests. Any mismatch must leave the draft unpublished;
apply the corresponding requirement in both documentation sites.

In `@docs/doctoring/RELEASE_SUPPLY_CHAIN_REFERENCES.md`:
- Around line 78-81: Update the candidate-tag deletion procedure to require
atomic ownership between final verification and ref removal: serialize all
tag/ref writers through one trusted release writer or enforce an atomic
compare-and-delete against the recorded tag object. If neither guarantee is
available while the ref may have changed, do not delete it; send it to
quarantine instead, while preserving the exact unpublished draft and
candidate-tag checks.

In `@tests/test_release_supply_chain_docs.py`:
- Around line 14-18: Update the assertions in the test loop over _ADR and
_RELEASE_GUIDE to validate the documented procedure as structured, ordered
relationships rather than independent keywords: require the immutability
endpoint and enabled: true within the same preflight step, then verify
annotated-tag type commit, peel, exact protected-source SHA, exact draft/tag
receipt checks, and deletion only afterward.

Owner-path convergence finding on exact head 9dfb79da481e37fe10e86e279f50b48179770dd1: the branch still documents .github#1782 as open and the canonical exact-artifact handoff as unresolved. That authority moved: .github#1791 merged the acyclic receipt repair as protected-main commit bd866a21cca2a7e709f0b7a88150c310a9d98239, and the current protected .github/main descends from that commit. At bd866a…, source-identity.json no longer contains the outer artifact digest, while the reusable still verifies GitHub's artifact ID/name/digest as an outer receipt before and again inside the credentialed signer boundary. Repair this branch by pinning that immutable owner SHA in the Proposed ADR/operator contract and removing only the resolved #1782 prerequisite; keep #911 and the still-unimplemented product-local release workflow as RED. Do not pin mutable .github/main or copy the verifier locally.
