From 8a8cffbdf530c10094566b3920bf61748482a4ad Mon Sep 17 00:00:00 2001 From: Jason Walker <913443@dadeschools.net> Date: Tue, 7 Jul 2026 09:57:50 -0400 Subject: [PATCH 01/60] feat: gate reviewer mutations on canonical workflow load proof (Closes #389) Add gitea_load_review_workflow and in-process session proof required before gitea_submit_pr_review, gitea_mark_final_review_decision, and gitea_merge_pr.

<913443@dadeschools.net> Date: Tue, 7 Jul 2026 11:32:25 -0400 Subject: [PATCH 02/60] feat: add precise validation status vocabulary for reviewer reports (Closes #406) Introduce

2001 From: Jason Walker <913443@dadeschools.net> Date: Tue, 7 Jul 2026 13:03:23 -0400 Subject: [PATCH 03/60] feat: enforce reconciler PR-close proof fields in final reports (Closes #306) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #306. The dedicated reconciler close path (profile, gated close tool, ancestor proof, tests) already shipped across #301/#304/#309/#310, but the final-report validator did not require a reconciler close to prove itself. A handoff could report `PRs closed: #N` while omitting the close capability, ancestor proof, or linked-issue result and still grade A. This adds the missing report-time enforcement. Changes: - final_report_validator.py — new `reconcile.close_proof_fields` rule (`_rule_reconcile_close_proof`). Fires only when a PR close is reported (via the `PRs closed` field or a `reconciler_close_lock`), then blocks unless the handoff carries close capability proof (gitea.pr.close), ancestor proof, PR close result, and linked-issue result. Comment-only and blocked reconciliations are unaffected. New optional `reconciler_close_lock` kwarg on `assess_final_report_validator`. - tests/test_final_report_validator.py — TestReconcilerCloseProof (6 cases): full-proof close passes; missing capability / ancestor / linked-issue result each block; session close lock requires proof; comment-only needs no close proof. - reconcile-landed-pr.md — §18A documents the enforced gate.

Jason Walker <913443@dadeschools.net> Date: Tue, 7 Jul 2026 11:35:43 -0400 Subject: [PATCH 05/60] feat: move duplicate-work detection before author mutations (Closes #400) Extract issue_work_duplicate_gate for open PR, remote branch, and active claim checks; wire it into lock_issue, commit_files recheck, and create_pr recheck.

(#400) Expose issue_duplicate_context_fetcher on the MCP server so lock_issue, commit_files, and create_pr duplicate rechecks avoid live Gitea calls in unit tests.

00:00:00 2001 From: Jason Walker <913443@dadeschools.net> Date: Tue, 7 Jul 2026 16:32:23 -0400 Subject: [PATCH 16/60] test: fix reviewer lease gate regressions in MCP integration tests (#407) Align merge/review/audit mocks with the per-PR reviewer lease gate introduced in #407: install owned session leases after init_review_decision_lock, stub _fetch_pr_comments and _authenticated_username to

[PATCH 23/60] fix: resolve conflicts for PR #421 From d042a9ca244fe2944a94727df80290570a39325d Mon Sep 17 00:00:00 2001 From: Jason Walker <913443@dadeschools.net> Date: Tue, 7 Jul 2026 16:27:10 -0400 Subject: [PATCH 24/60] feat: replace global issue lock with keyed persistent store (Closes #443) Store per remote/org/repo/issue locks under GITEA_ISSUE_LOCK_DIR with atomic writes and per-session binding. Integrate own-branch adoption for lock recovery, update worktree-start and cleanup reconcile, and add tests documenting the ban on manual global lock seeding.

33/60] feat: surface explicit adoption proof in gitea_lock_issue response (Closes #477) When gitea_lock_issue adopts an existing own branch, the live tool response now carries explicit, citable adoption-proof fields so #473-style recovery sessions can quote the lock output directly instead of inferring adoption from separate offline checks. - issue_lock_adoption.py: add DECISION_LABELS + decision_label()/ safe_next_action() helpers; extend build_adoption_proof() with adoption_decision, adopted, adopted_branch, adopted_branch_head, matcher_summary (boundary-safe reason), competing_branch_check, and safe_next_action for all outcomes; add build_non_adoption_lock_proof() for adoption-free NO_MATCH metadata. - gitea_mcp_server.py: attach adoption-free adoption_check block to normal (non-adopt) lock responses so they cannot be misread as claiming adoption. - docs/llm-workflow-runbooks.md: document the adoption/adoption_check response blocks and instruct recovery reports to cite them directly. - tests: explicit-field proof for ADOPT/BLOCK_COMPETING/NO_MATCH, substring-collision boundary safety (issue-42 vs issue-420), non-adoption proof, and MCP-level live-response assertions. BLOCK_COMPETING lock attempts still fail closed (raise); no raw API fallback, branch deletion, force-push, or manual lock seeding introduced.

charset=UTF-8 Content-Transfer-Encoding: 8bit Normal author work is unchanged: gitea_lock_issue still requires the worktree to be base-equivalent to master/main/dev, and gitea_create_pr still targets a normal base branch. A *stacked* PR (based on another unmerged PR's branch) is a new explicit, proof-backed path — it never bypasses the issue lock. - stacked_pr_support.py: pure policy. Approve a non-master base only when it is declared AND owned by a live OPEN PR whose number matches; reject arbitrary, mismatched, or stale (merged/closed) branches; require the PR body to document the stack (base branch, stacked-on PR, merge ordering). - issue_lock_worktree.py: read_worktree_git_state / _find_matching_base_ref gain an opt-in extra_bases arg so an approved stacked base can anchor base-equivalence in addition to master/main/dev (empty by default = unchanged). - gitea_mcp_server.py: - gitea_lock_issue gains stacked_base_branch + stacked_base_pr. When declared, it verifies the open PR owns the branch, anchors base-equivalence to it, and records approved_stacked_base = {branch, pr_number, verified_open} on the lock. - gitea_create_pr validates a non-master base against the lock's approved stacked base, re-checks the dependency PR is still open, and enforces the stacked-PR body fields. Master-based path untouched. - Docs: llm-workflow-runbooks.md and work-issue.md document when stacked PRs are allowed and the required PR-body wording. Tests: test_stacked_pr_support.py (18 policy cases), stacked base-equivalence in test_issue_lock_worktree.py, approved_stacked_base persistence round-trip in test_issue_lock_store.py. Existing lock/create_pr regressions still pass. The #482 -> #479/#478 case motivates this: create_pr previously could not open a stacked PR because the lock required a master-equivalent worktree.

cedf451a2ba635d42ebe7d35391abe11ceb5daf8 Mon Sep 17 00:00:00 2001 From: Jason Walker <913443@dadeschools.net> Date: Tue, 7 Jul 2026 11:56:44 -0400 Subject: [PATCH 38/60] feat: add session-owned worktree cleanup audit and TTL enforcement (Closes #401) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Stale worktrees accumulate under branches/ when runs stop early, race a sibling session, hit a validation failure, or lose cwd state, making later workflow decisions harder and riskier. Changes: - worktree_cleanup_audit.py — ownership metadata, safety-first classifier (active_open_pr, active_issue_work, dirty_local_worktree, clean_stale_removable, detached_review_leftover, unsafe_unknown), TTL expiry, per-worktree removal proof, and success-completion cleanup plan. Only clean_stale_removable and detached_review_leftover are removable; dirty/PR/leased/protected/unknown worktrees are never auto-deleted. - gitea_audit_worktree_cleanup — read-only MCP tool that classifies every branches/ entry, fetches live open-PR heads (fails closed if unavailable), and returns counts, removable candidates, and git worktree list proof. - work-issue.md 22A + review-merge-pr.md 28 — cleanup/TTL workflow rules. - tests/test_worktree_cleanup_audit.py — 30 cases covering all nine acceptance scenarios plus inference, metadata, TTL, and report accuracy. Validation: /Users/jasonwalker/Development/Gitea-Tools/venv/bin/python \ -m unittest tests.test_worktree_cleanup_audit tests.test_merged_cleanup_reconcile -q 38 passed.

Each role uses its own worktree env var with actionable binding-source errors and safe reconnect guidance.

<913443@dadeschools.net> Date: Wed, 8 Jul 2026 04:23:17 -0400 Subject: [PATCH 44/60] feat: add safe post-merge moot lease cleanup for already-merged PRs (Closes #515) Refuse merge-oriented reviewer-lease acquisition/adoption on an already merged/closed PR, and add a read-first cleanup path for a lingering moot lease. - reviewer_pr_lease.assess_acquire_lease: new pr_merged_or_closed flag; fail closed with a post_merge_moot reason and no lease body when the PR already merged/closed. - reviewer_pr_lease.assess_post_merge_moot_lease: pure assessment. Only treats a lease as moot when the PR is merged/closed; never proposes touching an active lease on an open PR; provides a terminal phase:released (blocker: post-merge-moot) body to neutralise the moot lease append-only; idempotent once the released marker is the newest entry. - gitea_acquire_reviewer_pr_lease: fetch live PR state, pass the flag, surface post_merge_moot on refusal (no comment posted). - gitea_cleanup_post_merge_moot_lease: new read-first tool. Reports merged state, merge_commit_sha, linked-issue closure, lease-moot, cleanup performed/skipped, and no_merge_or_adoption. apply=True posts the released marker only when merged/closed with an active lease; refuses on open PRs. - tests/test_post_merge_moot_lease.py: 10 tests covering acquire refusal on merged PR (no post), safe/idempotent cleanup, and open-PR foreign-lease protection. No relaxation of #407 reviewer-lease or #16 gated-merge gates for open PRs.

00:00:00 2001 From: Jason Walker <913443@dadeschools.net> Date: Wed, 8 Jul 2026 12:03:14 -0400 Subject: [PATCH 49/60] fix: preserve actual reconciler role for #274/#475 role exemptions during comment_issue preflight (Closes #540) resolve_task_capability("comment_issue") stamps _preflight_resolved_role = "author" because comment_issue.required_role_kind = author. _effective_workspace_role() prefers that stamp, so a genuine prgs-reconciler session was classified as an author inside the #274 branch-only mutation guard and the #475 root checkout guard, blocking gitea_create_issue_comment from the control checkout. Fix keys the role exemptions off the actual active profile role as well as the effective workspace role: - Add _actual_profile_role(): derives the workspace role from the active profile alone, never from _preflight_resolved_role. - _enforce_branches_only_author_mutation: exempt when EITHER the effective role OR the actual profile role is a non-author role. - _enforce_root_checkout_guard: pass actual_role; assess_root_checkout_guard now exempts a reconciler by resolved OR actual role. Author blocking is preserved: an actual author profile classifies as author in both signals, so it stays blocked on a contaminated control checkout. Merger strictness stays keyed on the resolved task role so a merger operating from its clean branches/ workspace under a non-merge task is not over-tightened. Regression tests (tests/test_issue_540_comment_role_poison.py) cover the reconciler comment path, author-blocking path, reviewer/merger/reconciler role classification under a poisoned author stamp, and the root guard actual_role exemption.

This forced temp local patches during #542/#517 merge/reconcile. - Remove the redundant verify call (the _verify already performs purity verification with correct worktree_path). - Update test to reflect single invocation path and add explicit test proving state preservation, single call, no dupe clear, and no need for raw/temp fallbacks. - Reconciler/controller flows stay fully MCP-native.

Add remote_repo_guard.assess_remote_repo_match (pure) + formatter, wired into gitea_mcp_server._resolve so every read/lookup/mutation tool fails closed when the MCP-resolved org/repo disagrees with the local git remote URL and the caller did not pass explicit org/repo. The guard is best-effort: it skips when both org and repo are explicit, when the local remote URL is unavailable, and is bypassed under pytest unless GITEA_FORCE_REMOTE_REPO_CHECK is set. Add tests/test_remote_repo_guard.py (pure-function cases + server wiring proving a lookup tool cannot silently query a different repository), and update author/reviewer/merger handoff templates to require explicit remote/org/repo.
