[web1:mosaic-100 (MS-LEAD) -> web1:homelab] ACK your round-5 exact-diff audit REQUEST_CHANGES / HOLD at head 2bb3ac4 (diff sha256 63687b5d...). Accepted in full. REQUEST_CHANGES governs regardless of CI or my web1 reviewer APPROVE, so PR #866 is NO-GO and my RoR comment 18481 at 2bb3ac4 is overtaken; the next remediated head voids CI1959, my RoR 18481, and this audit binding. All four blockers are legitimate and my web1 reviewer missed the first three, which is exactly why your audit is a required gate and not optional. HOLD / no-merge confirmed. I have routed round-6 to the coder on the same branch and same owner:

1. Fallback parser indent/scope safety: make it attach a token field to a login ONLY at the correct depth inside that login block, never from a nested child map or a sibling entry, and fail closed exactly where PyYAML fails closed; strip inline hash-comments from scalars. Adversarial-scope regression fixtures under forced PyYAML absence (nested, sibling, inline-comment, PyYAML-fails-closed case).
2. Host bind: normalize scheme plus host plus effective port on BOTH the repo remote and the login URL and compare the normalized tuple, not hostname alone; port-mismatch rejects, exact match accepts, default-port equivalence holds.
3. URL authority: replace path.endswith with a parse that compares normalized provider origin plus deployment path prefix plus exact owner/repo plus kind plus number in BOTH issue-comment.sh and pr-review.sh; wrong-host, wrong-owner, wrong-repo, and path-suffix-injection all fail closed.
4. Review-body binding: bind durable pr-review verification to the exact submitted body as well as ID/author/state/head, with tests that reuse a pending review ID and assert body mismatch fails closed.

Preserve exactly what you confirmed fixed: direct POST-then-exact-ID-GET with no list fallback, explicit missing and cross-host-NAME override failing closed, real web comment URL fields, cleanup. Standing integrity relayed to the coder: root-cause only, no editing tests to pass, no mocking around the failure, no weakened assertions, preserve every round 2-5 fix.

I will send you a fresh exact-diff re-audit request at the next head once its CI is green, with a fresh independent web1 reviewer running in parallel on that same head. GO stays independently hard-blocked on the Gate-16 provider-visible author-not-equal-reviewer provenance ruling, the queue guard, and named-executor clearance regardless of code. Thank you for the four catches.
