[Governance][ACV2 WP-B] Authorize source-closure amendment 2 v2

[laiqian0239-glitch]

Prospective trusted-main Amendment-2 v2 authorization for ACV2 WP-B M3 source closure after the generic delegated forwardContinuation root repair merged in #468.

Evidence and invariants:

• trusted main/base: c29d1101d503a18ab805b02df65a3d5f22dfdede;
• PR [Governance][ACV2 WP-B] Authorize source-closure scope amendment 2 #466 remains immutable Draft review RED evidence and is not rewritten/rebased;
• frozen Amendment-1 implementation head: a9ac7e0a5ed8d3e79435942d4f1fa3160036e029;
• exact implementation scope remains 223 paths, SHA-256 32de20189a35c556389b567334e68a7909a9b7a8e5ce24c5c04f0cf46316cbef;
• exact differential remains 11 paths, SHA-256 03b81e7c16cef3d7d604e83679d7a9fb95d3163dfb1ba14c10c173a4014d9b73;
• current source-closure truth remains 14 OPEN / UNREGISTERED=0;
• proposal schema and repository-native authorization proposal transport are GREEN with implementation authority remaining false.

Machine continuation contract after effective ordinary merge:

• new implementation branch: product/acv2-wp-b-m3-source-closure-successor-amendment-2-v2;
• first continuation commit must have exactly two parents;
• parent 1 = effective Amendment-2 v2 authorization merge;
• parent 2 = frozen predecessor a9ac7e0a5ed8d3e79435942d4f1fa3160036e029.

No gate/scanner weakening, workaround, retroactive self-authorization, cherry-pick duplication, rebase, force-push, history rewrite, duplicate Facebook Page production transport, or new general-purpose Yance infrastructure is authorized. Mature existing Chatwoot/Matrix and WP-B durable execution seams remain the selected fit.

Merge policy: exact-head CI + independent P0=0/P1=0 + unresolved threads=0 + fresh-main anti-drift, then ordinary merge commit only.

Warning

Review limit reached

@laiqian0239-glitch, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 42 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Adds an Amendment-2 v2 governance authorization document. It defines a scoped successor branch, preserves approved paths, restricts implementation and reuse, records evidence, and requires validation, independent review, and an ordinary two-parent merge.

Changes

Amendment-2 v2 authorization

Layer / File(s)	Summary
Authorization contract governance/layered-ci/acv2-wp-b-m3-source-closure-successor-scope-amendment-2-v2-authorization.json	Defines Amendment-1 supersession, trusted-main lineage, canonical SHA-256 path digests, the 223 approved paths, 11 newly authorized paths, dependencies, workflow scope, and implementation restrictions.
Continuation and reuse controls governance/layered-ci/acv2-wp-b-m3-source-closure-successor-scope-amendment-2-v2-authorization.json	Defines the required forward continuation, successor topology, approved existing seams, prohibited duplicate infrastructure, and frozen predecessor history.
Validation and merge gates governance/layered-ci/acv2-wp-b-m3-source-closure-successor-scope-amendment-2-v2-authorization.json	Defines focused validation, exact-head CI, negative proofs, independent-review thresholds, fresh-main anti-drift checks, and ordinary two-parent merge requirements.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to f49b7

The authorization document contains inconsistent lineage values for the first continuation commit, so merging it could authorize a successor with the wrong second parent and break the required history contract. This concrete merge-readiness issue should be corrected or explicitly reconciled before merge.
