feat: add master-parity staleness gate for MCP mutations (Closes #420 ) 934688a71d

The MCP server loads capability-gate code into memory at startup, so a
newly merged gate (e.g. the branch-delete capability gate #408/#410) does
not take effect until the process restarts. A long-running server could
therefore still perform a mutation the updated codebase forbids.

Runtime profile/config data is already read live from disk each call
(gitea_config.load_config re-reads the JSON), so allowed_operations changes
apply without a restart. This closes the remaining gap: *code* parity.

- master_parity_gate.py: capture the process's startup commit and, at
  mutation time, compare it against the on-disk master HEAD; pure,
  injectable assessment plus block-reasons and a restart-required report.
- gitea_mcp_server.py: capture _STARTUP_PARITY at import; _profile_operation_gate
  fails closed for mutating ops when stale while leaving gitea.read allowed;
  gitea_get_runtime_context surfaces master_parity; new read-only
  gitea_assess_master_parity tool reports parity/restart-required.
- Escape hatches: GITEA_MCP_DISABLE_PARITY_GATE (ops), GITEA_TEST_CURRENT_HEAD (tests).
- tests/test_master_parity_gate.py: 18 cases (pure logic, block/report,
  read override, and server wiring: reads pass, mutations blocked when stale).

Validation: venv/bin/python -m pytest -q -> 1618 passed, 6 skipped.

The review of PR #444 (feat: add server code parity gate for mutations) has completed successfully.

Verified that master_parity_gate.py implements pure commit baseline checks correctly.
Verified that gitea_mcp_server.py integrates the gate in _profile_operation_gate, failing closed for all mutating operations when server code is stale relative to master.
Confirmed that read-only operations (gitea.read) are explicitly bypassed and unaffected.
Confirmed gitea_assess_master_parity provides safe, detailed, structured diagnostics and recovery instructions when stale.
Confirmed the test suite in tests/test_master_parity_gate.py comprehensively covers the gate behavior, including env var disable and override switches, and all 1618 tests pass cleanly.

All acceptance criteria are fully met. Approved!

Review findings (re-review at head `e97b1d3`) — formal REQUEST_CHANGES blocked this run

Context: Oldest open PR in queue (oldest-first). Prior sysadmin APPROVED at 934688a is stale vs live head e97b1d3642c89c0eb5d5fd4cd50e318f20058f43 (conflict-resolution commits landed after approval).

Blocking defect (conflict-resolution regression)

Inserting gitea_assess_master_parity reused the @mcp.tool() decorator that previously belonged to gitea_record_pre_review_command.

Proof (tool registration set vs prgs/master):

LOST on this head: gitea_record_pre_review_command
ADDED on this head: gitea_assess_master_parity
Net @mcp.tool() count still 68 (swap, not add)

At gitea_mcp_server.py ~7644–7645:

    return out
def gitea_record_pre_review_command(

Missing blank line + missing @mcp.tool() before gitea_record_pre_review_command.

Scope / tests (otherwise OK)

Diff vs master is still the intended three files: master_parity_gate.py, wiring in gitea_mcp_server.py, tests/test_master_parity_gate.py.
pytest tests/test_master_parity_gate.py → 18 passed in worktree at e97b1d3.
Core gate logic looks sound (reads never blocked; mutations fail closed when stale; env escape hatches).

Required fix before re-approve

Restore @mcp.tool() on gitea_record_pre_review_command.
Keep @mcp.tool() on gitea_assess_master_parity (net +1 tool vs master).
Push fix; re-request review at new head.

Process note

This reviewer MCP process already consumed its terminal review mutation on merged PR #574 (#332 one-terminal-per-run). Formal REQUEST_CHANGES / APPROVED cannot be submitted until the gitea-reviewer MCP server is restarted. This comment is diagnostic only — not a formal review verdict.

Identity: sysadmin / prgs-reviewer
Candidate head reviewed: f04f61058f3c8561740efb22de2b25d8b1154e7f
Target: master @ 066eec84771a3811fa6e890e1a3241c3441921ae
Formal review mutation: not submitted — active conflict-fix lease (author jcwalker3, worktree branches/issue-420-master-parity-gate, phase=claimed) blocks gitea_mark_final_review_decision. Separate reviewer lease (session 3568-fd7afe4d41ba, candidate head stale at e97b1d3) also blocks lease acquire.

Intended formal verdict (when leases clear): REQUEST_CHANGES

Blocking defect at current head: conflict-resolution regression dropped @mcp.tool() from gitea_record_pre_review_command when inserting gitea_assess_master_parity.

Evidence:

PR head ~L7794–7795: return out then def gitea_record_pre_review_command( with no decorator
Clean prgs/master still has @mcp.tool() above that function
@mcp.tool() count stays 68 (new tool steals the slot; record is no longer MCP-registered)
Impact: #403 gitea_record_pre_review_command would not be exposed after merge

Required fix:

Restore @mcp.tool() above gitea_record_pre_review_command
Blank line after return out in gitea_assess_master_parity
Prefer a small regression test that the tool remains registered

Validation (official, clean worktree)

Worktree: branches/review-pr-444-f04f610 @ f04f610 (clean before/after)
pytest tests/test_master_parity_gate.py -q → 18 passed
py_compile of touched modules → ok
Prior APPROVE at 934688a is stale vs live head (approval_at_current_head=false)

Non-blocking notes

Core master_parity_gate design looks correct (fail closed on stale mutations; reads allowed)
Linked issue #420 remains open (status:in-progress)

Do not merge on stale approvals. After leases release + decorator fix, re-run reviewer workflow for formal REQUEST_CHANGES or APPROVE.

Code finding — do NOT approve yet

Conflict-resolution / master-merge head still has the decorator regression reported earlier for e97b1d3:

Inserting gitea_assess_master_parity reused the @mcp.tool() that previously belonged to gitea_record_pre_review_command.
Registration vs prgs/master at this head: LOST gitea_record_pre_review_command, ADDED gitea_assess_master_parity, net tool count unchanged (swap).
Source: after return out of gitea_assess_master_parity, def gitea_record_pre_review_command has no @mcp.tool().

Required author fix before re-approve:

Restore @mcp.tool() on gitea_record_pre_review_command.
Keep @mcp.tool() on gitea_assess_master_parity (net +1 tool).
Push; re-request review at the new head.

Otherwise OK on this head

Scope vs master still three files: master_parity_gate.py, gitea_mcp_server.py, tests/test_master_parity_gate.py.
pytest tests/test_master_parity_gate.py → 18 passed; related suite 57 passed.
git merge-tree --write-tree prgs/master HEAD clean; live mergeable true.
Gate logic (reads never blocked; mutations fail closed when stale) still looks sound.

Formal review mutation blocked
