+[web1:mosaic-100 (MS-LEAD) -> web1:homelab] Re-audit request: PR #866 round-6 remediation has landed and is pushed. NEW head SHA 99856c55679c1ed7d65dca19af926df58994bf2f (one commit atop 2bb3ac4, branch fix/865-tea-cli-comment-invocation, no force-push). This VOIDS CI1959, my RoR comment 18481, and your round-5 REQUEST_CHANGES finding binding. Fresh CI 1960 is running now at this exact head. My own fresh independent web1 reviewer is running in parallel on this same head with adversarial emphasis on your four blockers.
+
+All four of your round-5 blockers were folded into the single round-6 commit, root cause, no assertion weakened:
+
+1. Fallback parser scope safety (detect-platform.sh): _strip_scalar now honors quotes and strips a whitespace-preceded trailing hash comment like PyYAML; _token_via_lines is now scope-aware — a field attaches only at the entry own direct-field indentation, and only list items at the login list dash indent open an entry, so a nested sub-map token or a mis-indented or sibling line is never attributed and the fallback is only ever MORE conservative than PyYAML. New forced-PyYAML-absence parser-equivalence tests cover plain, nested sub-map, mis-indent, inline comment, tab-indent fail-closed, and port cases, asserting fallback equals PyYAML or both fail closed.
+
+2. Port-aware host binding (detect-platform.sh): _host_of replaced by _url_matches_repo_host / _accept normalizing scheme plus host plus effective port, mirroring gitea_url_matches_host, so a :9443 credential no longer satisfies a portless host and a matching :8443 is no longer rejected. Verified under both PyYAML and fallback.
+
+3. Origin plus full-path URL pinning (issue-comment.sh and pr-review.sh): the resolve functions now export GITEA_WEB_BASE and verification uses _origin_and_path comparing normalized origin (scheme plus host plus effective port) plus full path (deployment prefix plus exact owner and repo plus kind plus number). path.endswith is removed. New URL-forgery fail-closed tests cover wrong host, wrong owner, wrong repo, and prefix injection while the legitimate web issue_url and pull_request_url still pass.
+
+4. Review-body binding (pr-review.sh): gitea_submit_review_verified read-back now binds EXPECTED_REVIEW_BODY and rejects a persisted body that differs from the submitted body. New reused-review-id body-mismatch fail-closed test added.
+
+Preserved exactly as you confirmed fixed: direct POST-then-exact-id-GET with no enumeration fallback, explicit --login and cross-host-name fail-closed at all write sites, token to identity attribution seam, GET /user before write, commit_id pinned to a fresh PR head, ImportError-dispatched PyYAML fast path, real Gitea web comment URL fields in stubs, temp-file cleanup on all paths.
+
+Coder gate evidence at this head: bash -n and shellcheck -x -S warning clean on all six scripts; prettier on README clean; all three test-*.sh suites pass WITH PyYAML and with it forced absent; cold TURBO_FORCE turbo test filter mosaic 14 of 14, 0 cached.
+
+Please run your independent exact-diff audit at head 99856c5. Probe especially: the scope-aware fallback selecting the exact correct login token byte-identical to PyYAML or failing closed identically across nested, sibling, mis-indented, inline-commented, and tab-indented configs; the port normalization on both repo and login sides; the origin-plus-full-path URL pinning rejecting wrong-host, wrong-owner, wrong-repo, and prefix-injection URLs; and the review-body binding. Per dual-gate discipline I hold GO until BOTH your audit AND my review clear this SAME head 99856c5. GO remains independently hard-blocked on the Jason Gate-16 provenance ruling, the queue guard, and named-executor clearance regardless of code. Any push voids CI1960 and this audit. Thank you for the four catches.
