Closes #15.

Summary

Adds gitea_submit_pr_review, the only tool that submits a Gitea PR review. It performs a review mutation (comment / approve / request_changes) only after every safety gate passes, and it never merges.

Review action → (eligibility action, Gitea review event):

comment → eligibility review, event COMMENT
approve → eligibility approve, event APPROVE
request_changes → eligibility request_changes, event REQUEST_CHANGES

Safety gates (fail-closed at each step)

Validate action is comment | approve | request_changes (unknown action → no API call).
Reuse gitea_check_pr_eligibility (#14): authenticated-user lookup, active-profile lookup, PR-author lookup, self-approval block, and profile-allowed-operation check.
Redundant self-approval block (authenticated user == PR author).
Optional expected_head_sha: refuse if the PR head has moved.
Only then POST the review.

Endpoint used (and why)

POST /repos/{owner}/{repo}/pulls/{n}/reviews — the formal review API, which records an APPROVE / COMMENT / REQUEST_CHANGES review state tied to the head commit. Chosen over the plain issue-comment endpoint (/issues/{n}/comments) so approvals and change requests carry real review state; a plain comment cannot approve or block a PR.

Files changed

mcp_server.py — new gitea_submit_pr_review tool + _REVIEW_ACTIONS map and _redact helper.
tests/test_mcp_server.py — new TestSubmitPrReview suite (14 tests).
README.md — one tool-table row.

Validation performed

python3 -m py_compile mcp_server.py tests/test_mcp_server.py gitea_auth.py — OK
git diff --check — clean
pytest tests/test_mcp_server.py — 64 passed
Grep of the diff for merge/Jenkins/Ops/GlitchTip/Release/deploy behavior — only comments stating merge is intentionally absent.

Tests cover: self-author approve blocked; approve / request_changes / comment succeed only when eligible; unknown identity fail-closed; disallowed profile op blocked; head-SHA mismatch blocked; no mutation when gates fail; invalid action rejected; secret redaction in both output and error paths.

Statements

Merge behavior was NOT added — merge belongs to #16.
Review mutations are gated by identity + profile + eligibility (#14) checks; the mutating call runs only after all gates pass.
Self-approval is blocked (via #14 and a redundant guard).
No real secrets were added; token/Authorization header/credentials never appear in output, and error text is scrubbed via _redact.
No Jenkins/Ops/GlitchTip/Release/deploy/rollback/migration/restart/production behavior was added.

Closes #15. ## Summary Adds `gitea_submit_pr_review`, the only tool that submits a Gitea PR **review**. It performs a review mutation (`comment` / `approve` / `request_changes`) **only after every safety gate passes**, and it never merges. Review action → (eligibility action, Gitea review event): - `comment` → eligibility `review`, event `COMMENT` - `approve` → eligibility `approve`, event `APPROVE` - `request_changes` → eligibility `request_changes`, event `REQUEST_CHANGES` ### Safety gates (fail-closed at each step) 1. Validate action is `comment` | `approve` | `request_changes` (unknown action → no API call). 2.

Redundant self-approval block (authenticated user == PR author). 4. Optional `expected_head_sha`: refuse if the PR head has moved. 5.

feat: add gated gitea_submit_pr_review review actions (#15 ) f05e58c847

Add gitea_submit_pr_review, the only tool that submits a Gitea PR review.
It performs a review mutation (comment / approve / request_changes) only
after every safety gate passes, and never merges.

Gates (fail-closed at each step):
  1. Validate action is comment | approve | request_changes.
  2. Reuse gitea_check_pr_eligibility (#14) for authenticated-user lookup,
     active-profile lookup, PR-author lookup, self-approval block, and the
     profile-allowed-operation check. approve requires 'approve' eligibility,
     request_changes requires 'request_changes', comment requires 'review'.
  3. Redundant self-approval block (auth user == PR author).
  4. Optional expected_head_sha: refuse if the PR head has moved.
  5. Only then POST /repos/{owner}/{repo}/pulls/{n}/reviews (formal review
     endpoint, so approvals/change-requests carry real review state).

Output reports action, whether performed, authenticated user, profile name,
PR author, PR number, head SHA checked, and reasons — never a token, auth
header, or credential. Error text is scrubbed via _redact as defence in depth.

Merge is intentionally not implemented (belongs to #16).

Tests cover: self-author approve blocked, approve/request_changes/comment
succeed only when eligible, unknown identity fail-closed, disallowed profile
op blocked, head-SHA mismatch blocked, no mutation when gates fail, invalid
action rejected, and secret redaction in output and error paths.

Independent review for issue #15 is held.

Validation performed:

PR #25 is open and targets master.
Authenticated Gitea account is jcwalker3, which matches the PR author, so I cannot approve this PR from this account.
Commit reviewed: f05e58c.
Changed files verified exactly: README.md, mcp_server.py, tests/test_mcp_server.py.

pytest tests/test_mcp_server.py passed: 64 passed.

Manual review notes:

New gitea_submit_pr_review supports only comment, approve, and request_changes; it does not support merge.
New gitea_submit_pr_review gates through gitea_check_pr_eligibility, blocks self-approval, supports expected head SHA checking, and performs one POST /pulls/{n}/reviews mutation only after gates pass.
Tests cover eligible approve/request_changes/comment, self-author approve block, unknown identity, disallowed profile operation, expected head SHA mismatch, no mutation on gate failure, invalid action, and redaction paths.
No new Jenkins/Ops/GlitchTip/Release/deploy/rollback/migration/restart/production behavior, branch writes, multi-token switching, or real secrets found in the new PR diff.

Blockers:

Reviewer eligibility: current authenticated Gitea account is jcwalker3, same as PR author, so approval requires a different reviewer account.
Bypass risk: the older gitea_review_pr is still exposed with @mcp.tool() in mcp_server.py.
Bypass risk: gitea_review_pr can still submit review mutations directly via POST /pulls/{pr_number}/reviews without calling gitea_check_pr_eligibility.
Bypass risk: gitea_review_pr still accepts merge=True and can call POST /pulls/{pr_number}/merge without the new #14 eligibility gates.
Bypass risk: README still documents gitea_review_pr as “Submit a review on a pull request and optionally merge it.”

Because #15 adds gated PR review actions, leaving an exposed ungated review/optional-merge MCP tool creates a bypass around the new gated gitea_submit_pr_review path. I did not find a clear repository decision in this PR that #15 should intentionally leave that bypass available.

Fix applied: old gitea_review_pr bypass is closed. It now acts as a safe compatibility wrapper for gitea_submit_pr_review using the #14 eligibility gates. The merge path is disabled/removed from exposed review tooling and will fail closed if attempted. Tests were added to prove the bypass is closed, self-approval is blocked, and merge fails. Validation performed (pytest 66 passed). Confirmed that the #16 merge workflow was not implemented here.

Re-review for issue #15 after security blocker fix is held only due reviewer eligibility.

Validation performed:

PR #25 is open and targets master.
Authenticated Gitea account is jcwalker3, which matches the PR author, so I cannot approve this PR from this account.
Latest commit reviewed: 6c992a4.
Changed files verified exactly: README.md, mcp_server.py, tests/test_mcp_server.py.

Gated review action review:

gitea_submit_pr_review supports only comment, approve, and request_changes; merge is not in _REVIEW_ACTIONS.
It uses gitea_check_pr_eligibility before mutation.
It blocks self-approval, unknown identity/profile-derived no-allowed-operation cases, profile-disallowed actions, and expected-head-SHA mismatch before mutation.
It performs one POST /pulls/{n}/reviews only after gates pass.
Redaction is present for surfaced credential-like error text.

Legacy bypass status:

gitea_review_pr is still exposed as an MCP tool, but now acts as a compatibility wrapper around gitea_submit_pr_review.
merge=True fails closed before any API call.
It no longer calls the merge endpoint and no longer performs ungated review mutations.
Legacy self-approval is blocked through the same gated path.
README now documents gitea_review_pr as a legacy wrapper with merging disabled.
Tests are present for legacy merge fail-closed, legacy gate usage, and legacy self-approval block.

Manual review notes:

No new merge behavior, branch writes, multi-token switching, real secrets, auth header exposure, raw env leakage, credential path exposure, Jenkins/Ops/GlitchTip/Release/deploy/rollback/migration/restart/production behavior, or unrelated files found in the PR diff.
Existing gitea_merge_pr remains exposed and documented, but it is pre-existing and not added or modified by #15.

No remaining content blockers found. A different reviewer account is required to approve.
