# 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.
