+# Issue #812 — durable Gitea PR review comments
+
+- **Lane:** ms-812
+- **Branch:** `fix/812-pr-review-comment`
+- **Issue:** mosaicstack/stack#812
+- **Budget:** 15K working estimate; single focused shell-wrapper/test/docs change.
+
+## Objective
+
+Make the Gitea `comment` action in `packages/mosaic/framework/tools/git/pr-review.sh` use tea v0.11.1's supported `tea comment` command and report success only after provider read-back verifies the created comment against the intended repository, PR, and exact body.
+
+## Plan
+
+1. Add and commit a failing shell regression harness before production changes.
+2. Verify RED against the nonexistent `tea pr comment` fallback false-positive.
+3. Implement the minimal supported write plus ID-based provider read-back.
+4. Document that wrapper write output is not durable provenance until read-back succeeds.
+5. Run focused regression tests, touched-package tests, and repository quality gates.
+6. Run independent review, remediate findings, queue-guard, push, and open a PR. Stop at PR-open for coordinator review/merge.
+
+## Progress checkpoints
+
+- [x] RED regression committed and reported to mosaic-100 (`3585cdfa`)
+- [x] Initial minimal fix implemented (`c3a83833`)
+- [x] Focused and package tests green after dependency build
+- [ ] Independent review passed
+- [ ] PR opened and reported with exact head SHA
+
+## Tests run
+
+- RED: `bash packages/mosaic/framework/tools/git/test-pr-review-gitea-comment.sh` failed against the old path because `tea pr comment` fell back and the wrapper returned success.
+- GREEN: all `packages/mosaic/framework/tools/git/test-*.sh` harnesses passed.
+- `pnpm build` passed (23/23 tasks).
+- `pnpm --filter @mosaicstack/mosaic test` passed (67 files, 1278 tests).
+- Package and root typecheck/lint/format gates passed.
+- Codex security review found no issues.
+- Codex code review requested changes: tea v0.11.1 has no supported `tea api`; replace read-back with the existing host-scoped authenticated curl/API path when work resumes.
+
+## Risks / blockers
+
+- **Coordination hold:** Mos directed #812 to remain parked until in-flight #789 reaches terminal state because #789 actively uses `pr-review.sh`. Branch must be pushed but no PR opened.
+- Initial implementation's `tea api` read-back is not compatible with tea v0.11.1 and must be remediated before PR.
+- Tea output shape must provide a created comment ID in JSON; failure to parse must fail closed.
+- Read-back must not accept a pre-existing comment with the same body.
+- Existing approve/request-changes behavior must remain unchanged and covered.
+
+## Final verification evidence
+
+Parked pending #789 terminal. No PR opened.

+# Git provider wrappers
+
+These scripts provide host-aware GitHub and Gitea issue, pull-request, milestone, and CI operations.
+
+## Durable review provenance
+
+A successful provider write command—or a wrapper message based only on that command's exit code—is **not** durable review provenance. Review comments count as durable provenance only after the wrapper reads the created provider record back and verifies that it belongs to the intended repository and pull request and contains the exact submitted body (or verifies the provider-returned record ID).
+
+`pr-review.sh` therefore fails closed when a Gitea comment cannot be written, its created comment ID cannot be identified, or provider read-back does not match. It reports comment success only after that read-back verification passes.
