Replace the ungated gitea_merge_pr with a gated merge workflow. This is now
the only merge path the MCP server exposes; the merge API is called only
after every safety gate passes.
Gates (fail-closed at each step):
1. Merge method is merge | squash | rebase.
2. Explicit confirmation: confirmation must equal "MERGE PR <n>" (without it,
zero API calls are made).
3. Reuse gitea_check_pr_eligibility (#14) with action 'merge': proves the
authenticated identity, the active profile (and that it allows merge), the
PR author, blocks self-merge, requires the PR open, and fails closed when
the PR is not mergeable or mergeability is unknown.
4. Optional expected_head_sha: refuse if the PR head moved.
5. Optional expected_changed_files: refuse if the PR's changed file set differs.
6. Redundant self-merge block (auth user == PR author).
The force/ignore-checks option was removed — Gitea's own mergeable signal
(which reflects branch-protection required reviews/checks) must be positive,
so required approval/check state is honoured, never bypassed.
Output reports performed, authenticated user, profile name, PR author, PR
number, head SHA checked, merge method, gates passed/blocked, and merge
result / merge commit — never a token, auth header, or credential. Error text
is scrubbed via _redact.
Surface audit: no ungated merge path remains. The /merge endpoint appears only
inside gitea_merge_pr; gitea_review_pr fails closed on merge=True before any
API call; gitea_submit_pr_review has no merge parameter and 'merge' is not a
reviewable action. Tests assert all three.
Tests cover: merge succeeds only when all gates pass; self-author blocked;
unknown identity/profile blocked; profile without merge permission blocked;
missing/wrong confirmation blocked (no API call); head-SHA mismatch blocked;
changed-files mismatch blocked; closed PR blocked; non-mergeable blocked;
unknown mergeability fail-closed; no merge call when gates fail; invalid merge
method rejected; output and error redaction; and the no-ungated-merge-path audit.

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.

Add two explicit eligibility tests requested in review of PR #24:
- self-author blocked from 'approve' (eligible=false, reason
"authenticated user is PR author").
- 'merge' fails closed when Gitea reports mergeable=None (eligible=false,
reason "PR mergeability unknown").
Tests only; no implementation change. Behavior already enforced by
gitea_check_pr_eligibility.

Add a read-only MCP tool that decides whether the current authenticated
identity + active runtime profile is eligible to review, approve,
request_changes, or merge a specific PR. Evaluation only — it never
reviews, approves, requests changes, merges, or mutates anything.
Inspects: authenticated username (/user), active profile metadata
(allowed/forbidden operations), and PR facts (author, state, head SHA,
mergeability). Returns {eligible, requested_action, authenticated_user,
profile_name, pr_author, pr_state, head_sha, mergeable, reasons}.
Fail-closed rules:
- unknown action / unknown remote -> not eligible
- action not in allowed ops, or in forbidden ops -> not eligible
- identity undetermined -> not eligible
- authenticated user == PR author -> cannot approve/merge
- PR not open -> not eligible
- merge requires a positive mergeable signal
No token/auth-header exposure. No review/approve/request-changes
mutation. No merge mutation. No multi-token switching. No
Jenkins/Ops/GlitchTip/Release/deploy behavior.

Add a read-only MCP tool that reports the active runtime execution
profile so an LLM can inspect what the current process is configured to
do before deciding whether to attempt an action later.
- gitea_get_profile: returns profile_name, allowed/forbidden operation
categories, audit_label, token_source_name (a NAME, never a value),
base_url, remote, resolved server, and — optionally — the verified
authenticated username. Identity resolution fails soft and marks
identity_status (verified/unknown/unavailable/not_resolved); the
profile config is always returned. Never mutates Gitea.
- gitea_auth.get_profile(): extended with forbidden_operations,
audit_label, token_source_name from env (non-secret metadata).
- .env.example / README: document the new optional metadata vars and
the discovery tool.
- tests: metadata parsing, verified/unavailable/unknown identity paths,
skip-identity, and secret-redaction.
Read-only. No token exposure. No multi-token switching. No PR
eligibility, review, or merge workflow. No Jenkins/Ops/GlitchTip/
Release/deploy behavior.

Allow the same MCP server to run as separate MCP entries, each with its
own token and profile name, so roles stay task-scoped (the profile is
the role, not the LLM).
- gitea_auth.get_profile(): reads GITEA_PROFILE_NAME,
GITEA_ALLOWED_OPERATIONS, GITEA_BASE_URL as non-secret metadata.
Never reads/returns/logs the token.
- gitea_whoami now surfaces the safe profile metadata (name + allowed
operations) alongside identity; token still never exposed.
- .env.example: placeholder-only template for a runtime profile.
- .gitignore: track .env.example while keeping real .env* ignored.
- README: document multiple env-configured MCP entries.
- tests: profile defaults/parsing, token-never-included, whoami surfaces
profile without leaking token.
One token + one profile per process. No multi-token switching in a
single runtime. No approve/merge/eligibility workflow. No
Jenkins/Ops/GlitchTip/Release/deploy behavior. No real secrets.

Add a read-only MCP tool that calls Gitea's authenticated-user
endpoint (GET /api/v1/user) and returns safe identity metadata only:
username, display name, user id, email, server, and remote.
This lets future review/merge workflows prove which Gitea account the
MCP server is authenticated as, so self-review/self-merge can be
detected before acting — the blocker discovered during PR #8 dogfooding.
- Never returns the token, Authorization header, password, or secrets.
- Fails closed with a clear error if identity cannot be determined.
- No mutation; no profile switching; no review/approve/merge behavior.
Tests: identity mapping, secret-redaction, fail-closed, unknown-remote.
