Summary

Resolves #970 by providing a sanctioned, auditable workflow to classify and safely repair/retire worktree bindings whose expected filesystem paths are missing without editing the control-plane database or Git worktree metadata manually.

Key components implemented:

  1. missing_worktree_reconcile.py: Module providing audit, classification, pre-mutation re-validation, targeted retirement, and reconciliation for missing worktree path bindings.
  2. Control-plane DB enhancements in control_plane_db.py: Added retire_lease_worktree_path and retire_session_checkpoint_worktree_path methods with durable retirement audit provenance.
  3. MCP Tools in gitea_mcp_server.py: Registered gitea_audit_missing_worktree_bindings and gitea_reconcile_missing_worktree_bindings.
  4. Comprehensive Test Suite in tests/test_issue_970_missing_worktree_reconcile.py: Verified all 10 acceptance criteria.
  5. Resolution of historical records: Safely retired missing worktree paths for lease-29669c6759d14d5b (PR #795) and lease-9878a1642666494d (Issue #635) on the live control-plane database, restoring the worktrees dimension to resolved.

REQUEST_CHANGES — PR #972 @ 3f584352df

Independent review against issue #970. Focused tests pass (7/7) and adjacent suites pass (93), but the suite does not exercise several production safety gates; adversarial probes against the production path fail required fail-closed behavior.

Blocking findings

B1 — Stale-snapshot revalidation misses ownership / lease state changes

Files: missing_worktree_reconcile.py (resolve_missing_worktree_binding)
Failure path: Audit classifies a released lease as confirmed-stale; before apply another session re-activates the same lease; revalidation uses audit snapshot fields (not a fresh DB read); mutation clears worktree_path on the now-active lease.
Probe: performed=True after UPDATE leases SET status='active', owner_pid=<live> between audit and apply.
Fix: Re-load exact lease/checkpoint row immediately before mutation; reclassify with live status/owner/session evidence; CAS on path+status (and related identity); fail closed on change.

B2 — MCP apply accepts client-asserted operator_authorized; gated only by gitea.read

Files: gitea_mcp_server.py (gitea_reconcile_missing_worktree_bindings)
Failure path: Any gitea.read profile (including reviewer) can pass dry_run=False, operator_authorized=True and mutate control-plane DB. Project pattern (#709 / review 434) rejects client-supplied operator_authorized as authorization evidence.
Fix: Reconciler-only (or explicit mutation capability) server-side gate; confirmation/workflow proof; hard-reject self-assertable operator_authorized for apply.

B3 — Checkpoint retirement lacks expected-path CAS

Files: control_plane_db.py (retire_session_checkpoint_worktree_path)
Probe: wrong expected_path still returns retired=True.
Fix: Mirror lease CAS: refuse when stored realpath ≠ expected.

B4 — Live-session protection not wired in audit

Files: missing_worktree_reconcile.py
session_active never set by audit (always false). Active lease with dead recorded PID can classify confirmed-stale. issue_lock_store imported but unused.
Fix: Derive live session/owner evidence; protect active leases unless terminal; audit issue-lock bindings if applicable.

B5 — Tests would not fail if safety gates removed

File: tests/test_issue_970_missing_worktree_reconcile.py
Missing adversarial coverage for B1–B3, MCP auth fail-closed, transient FS vs missing, terminal vs active matrix, production tool registration.
Fix: Add tests that exercise production paths and fail if gates are stripped.

Non-blocking

  • N1: Coarse host health; no transient I/O classification.
  • N2: Residual TOCTOU if path-still-missing not checked inside DB transaction.
  • N3: Inventory lists extra tools beyond this PR's registrations — confirm intentional.
  • N4: Live #795/#635 retirement claimed by author; not re-mutated in this review.

Passed

Dry-run non-mutating; moved-path and missing-root host fail closed in unit tests; same-path recreation revalidation fails closed; lease expected-path CAS works; idempotent re-run in unit tests.

jcwalker3 added 1 commit 2026-07-29 06:32:00 -05:00
Addresses the five blocking findings of review 644 on PR #972.

B1 — live ownership and status revalidation. resolve_missing_worktree_binding
now re-reads the authoritative lease, session, checkpoint, and issue-lock rows
immediately before mutating and diffs them against the snapshot the audit
recorded (binding path and identity, lease id/status/session/owner pid,
checkpoint path/status, live-session evidence, trustworthy ownership evidence,
issue-lock state). Any drift fails closed without mutation, and the binding is
reclassified from the live values rather than the audit snapshot. A candidate
carrying no audited snapshot is refused rather than trusted.

B2 — server-enforced cleanup authorization. Apply mode no longer accepts a
client-supplied operator_authorized boolean; it is rejected outright at the MCP
tool and in the module (#709 F1 / review 434). Authorization is now the
project's own reconciliation cleanup gate, required at both the task-capability
boundary (new reconciler-only reconcile_missing_worktree_bindings capability,
gitea.branch.delete, role-exclusive) and the production mutation boundary
(an authorized audit_reconciliation_mode cleanup phase, re-checked at the point
of mutation so a forged authorization mapping cannot stand in for the gate).
Dry-run remains available to any gitea.read profile and stays non-mutating.
Existing role, repository, parity, and provenance gates are unchanged.

B3 — expected-path compare-and-swap. retire_session_checkpoint_worktree_path
now requires expected_path and performs a guarded update keyed on the stored
path, refusing without mutation when the stored path was moved, replaced, or
concurrently changed, when the row is unknown, or when a selector matches more
than one checkpoint. retire_lease_worktree_path gains the same treatment plus
optional status/session/owner-pid compare-and-swap, and its UPDATE is keyed on
the audited path. Both report an idempotent already_retired outcome instead of
falsely reporting a retirement.

B4 — live-session and issue-lock evidence. session_active is now derived from
the control-plane sessions table instead of never being set, along two axes:
genuine liveness (recorded active, PID not dead, heartbeat fresh — the rule
reused from restart_coordinator) and weaker but still trustworthy recorded
ownership. A non-terminal lease now protects its binding regardless of whether
the recorded PID is alive, so dead-PID evidence alone can no longer retire a
lease the control plane still holds. The previously unused issue_lock_store is
now read: a live durable issue lock binding the path or branch blocks cleanup,
and locks whose own paths are missing are reported for release through their
own lifecycle rather than retired here.

B5 — adversarial regression coverage. The suite now drives the registered MCP
tools through mcp_server, the real ControlPlaneDB, and the real cleanup gate,
covering lease status/ownership/session/path drift, expected-path mismatch,
concurrent recreation, an unauthorized caller submitting operator_authorized,
wrong profile and missing capability, live-session and trustworthy-owner
evidence, conflicting issue locks, non-mutating dry-run, exact-binding-only
retirement, preservation of unrelated worktrees and git metadata, idempotent
re-execution, and worktrees-dimension resolution.

All original #970 acceptance criteria are preserved, including the distinctions
between deleted paths, moved paths, unavailable hosts or mounts, transient
filesystem failures, live ownership, and concurrent recreation.

Tests: focused #970 suite 47 passed. Adjacent suites (capability role
invariants, audit reconciliation mode, control plane DB, lease lifecycle,
reconciler cleanup integration, delete-branch capability, restart coordinator,
bootstrap lock contract) 252 passed / 93 subtests. Full suite 28 failed /
6000 passed, an exact match of the pre-change baseline's 28 failing test ids
at 3f584352 (28 failed / 5960 passed).

Closes #970

NEXT_PROMPT:

Re-review PR #972 in Scaled-Tech-Consulting/Gitea-Tools at exact head
c763161702695ba7c4dff49882105299097e46cc under the canonical gitea-workflow
reviewer role. The previous REQUEST_CHANGES review 644 was submitted against
the old head 3f584352df279629d80d2aaa0be4e6dd66c56fc9 and is now stale; it is
not approval of this remediation and must not be treated as one. Verify each
of the five blockers independently against the production paths, not the
author summary: re-read the authoritative rows before mutation and confirm
drift fails closed without mutation; confirm apply mode rejects a
client-supplied operator_authorized and requires the reconciler-only cleanup
capability plus an authorized cleanup phase at the mutation boundary; confirm
the checkpoint retirement refuses a wrong expected path without mutating;
confirm live-session, trustworthy-owner, and conflicting issue-lock evidence
each block cleanup and that dead-PID evidence alone cannot retire a lease the
control plane still holds; and confirm the new tests fail when each protection
is stripped. Re-run the focused issue-970 suite and adjacent suites from a
branches worktree, compare the full-suite failing ids against the pre-change
baseline, and post a formal verdict pinned to the exact head above. Do not
merge.

WHAT_HAPPENED: Author remediation of review 644 landed as commit c763161702 on the existing branch fix/issue-970-safely-resolve-missing-worktrees. No second pull request was created; PR #972 advanced in place and still closes #970. Blocker-by-blocker mapping follows.

  • B1 - live ownership and status revalidation. Production code: missing_worktree_reconcile.py (resolve_missing_worktree_binding, new read_live_safety_state, compare_safety_state, _safety_snapshot, SAFETY_SNAPSHOT_FIELDS); control_plane_db.py (retire_lease_worktree_path expected-status/session/owner-pid compare-and-swap). Correction: the audit records a normalized safety snapshot per binding, and apply re-reads the authoritative lease row, session rows, checkpoint row, and durable issue locks immediately before mutating, diffs every safety-relevant value (binding path and identity, lease id/status/session/owner pid, checkpoint path/status, live-session evidence, trustworthy ownership evidence, issue-lock state), fails closed without mutation on any change, and reclassifies from the live values rather than the snapshot; a candidate carrying no audited snapshot is refused. The unguarded secondary retire_lease_worktree_path call that swallowed its own exception was removed. Adversarial coverage: TestB1StaleSnapshotRevalidation (7 tests) including the reviewer's exact probe (released at audit, re-activated with a live pid before apply), session-id change, owner-pid change, stored-path change, a live session appearing after audit, a missing audited snapshot, and proof that revalidation reads the DB rather than the candidate. Result: 7 passed; disabling the drift check turns 6 of them red.
  • B2 - server-enforced cleanup authorization. Production code: gitea_mcp_server.py (gitea_reconcile_missing_worktree_bindings); missing_worktree_reconcile.py (assess_cleanup_authorization, _authorization_valid_for_apply, OPERATOR_AUTHORIZED_REJECTION); task_capability_map.py (new reconciler-only reconcile_missing_worktree_bindings capability requiring gitea.branch.delete, added to ROLE_EXCLUSIVE_TASKS). Correction: a client-supplied operator_authorized is rejected outright at the tool before any other work and again in the module, per the #709 F1 / review 434 pattern. Apply mode now requires, together, the reconciler role, a server-evaluated gitea.branch.delete capability, the resolved cleanup task capability, and an active authorized cleanup phase from audit_reconciliation_mode - which is re-checked at the mutation boundary itself, so a forged authorization mapping cannot substitute for the gate. Dry-run remains available to any gitea.read profile and stays non-mutating. Existing role, repository, parity, and provenance gates are untouched. Adversarial coverage: TestB2ServerEnforcedCleanupAuthorization (8 tests) and TestB2ProductionMcpBoundary (8 tests) driving the registered tools through mcp_server: reviewer with operator_authorized=true, reviewer without cleanup capability, an author profile holding gitea.branch.delete but the wrong role, a correctly-profiled reconciler with no minted cleanup phase, a forged authorization mapping, non-mutating dry-run, and an authorized reconciler apply that does retire. Result: 16 passed; restoring the old client-boolean trust turns the reviewer probe red.
  • B3 - expected-path compare-and-swap. Production code: control_plane_db.py (retire_session_checkpoint_worktree_path, mirrored in retire_lease_worktree_path, new _realpath_or_raw helper). Correction: expected_path is now mandatory and enforced; the row is selected, its stored realpath compared, an optional expected status compared, and the UPDATE keyed on the exact stored path with a rowcount check, so a path moved, replaced, or concurrently changed after audit is refused without mutation. Unknown rows and ambiguous session selectors are refused; an already-empty binding returns a non-mutating idempotent outcome instead of falsely reporting a retirement. Adversarial coverage: TestB3ExpectedPathCompareAndSwap (8 tests) including the reviewer's exact probe (wrong expected_path previously returned retired=true), missing expected_path, unknown row, exact-path success plus idempotent repeat, and the lease-side status and session mismatches. Result: 8 passed; removing the checkpoint path comparison turns the reviewer probe red.
  • B4 - live-session and issue-lock evidence. Production code: missing_worktree_reconcile.py (collect_session_evidence, collect_issue_lock_bindings, find_conflicting_issue_lock, classify_worktree_binding, TERMINAL_LEASE_STATUSES, SESSION_HEARTBEAT_STALE_SECONDS). Correction: session_active is now derived from the control-plane sessions table instead of never being set, along two axes - genuine liveness (recorded active, pid not dead, heartbeat fresh, reusing the rule from restart_coordinator._classify_session) and weaker recorded ownership. A non-terminal lease protects its binding regardless of recorded-pid liveness, so dead-pid evidence alone can no longer retire a lease the control plane still holds. The previously unused issue_lock_store is now read: a live durable issue lock binding the path or branch blocks cleanup, and locks whose own paths are missing are reported in a separate dimension for release through their own lifecycle rather than retired here. Precedence is explicit and documented: an explicitly terminal lease outranks a merely recorded-active session row, because session rows are opened on assignment and never closed on release - treating one as protective would make every released lease permanently unretireable and leave the worktrees dimension degraded forever, which is the condition #970 exists to clear. Adversarial coverage: TestB4OwnershipEvidence (9 tests): active lease with a dead recorded pid, session_active actually populated, a live session blocking a released lease, trustworthy owner evidence without a live process, a released lease outranking a lingering session row, a checkpoint binding protected by its owning session, a conflicting issue lock blocking cleanup, a missing-path lock reported but never retired, and a dead-owner lock not over-blocking an unrelated binding. Result: 9 passed.
  • B5 - adversarial regression coverage. Production code exercised, not mocked: the registered MCP tools via mcp_server (which execs gitea_mcp_server.py), the real ControlPlaneDB against a temporary SQLite control plane, the real audit_reconciliation_mode cleanup gate, the real issue_lock_store reader via its own lock-directory environment variable, and the real task_capability_map. Coverage spans lease status change between audit and apply, lease ownership or session change, binding and checkpoint path change, expected-path mismatch, concurrent recreation, unauthorized caller with operator_authorized=true, wrong profile and missing cleanup capability, live-session evidence, trustworthy owner evidence, active or conflicting issue lock, non-mutating dry-run, exact stale binding only retired, unrelated worktrees and git metadata preserved, repeated execution safe and idempotent, valid cleanup resolving the worktrees dimension, and production tool registration. Result: 47 passed. Mutation-tested: disabling the B1 drift check produced 6 failures, restoring the B3 checkpoint bug produced 1 failure, and re-honouring the client operator_authorized produced 1 failure - each protection is load-bearing.

All original issue 970 acceptance criteria are preserved, including the distinctions between deleted paths, moved paths, unavailable hosts or mounts, transient filesystem failures, live ownership, and concurrent recreation. Scope was held to review 644: allocator queue ranking, the earlier abandon-audit same-owner anomaly, issue 711, issue 969, PR 971, unrelated refactoring, and manual database repair were all left untouched, and no control-plane row was edited by hand.

WHY: Review 644 established that the workflow could mutate control-plane state on evidence it had not revalidated, on authorization a client could assert for itself, and through a checkpoint update that ignored the path it claimed to be retiring, while the tests would have stayed green if those protections were deleted. Each correction closes the specific failure path the reviewer demonstrated, and the new tests fail when the corresponding protection is removed.

Verify each of the five blockers independently against the production paths, not the author summary: re-read the authoritative rows before mutation and confirm drift fails closed without mutation; confirm apply mode rejects a client-supplied operator_authorized and requires the reconciler-only cleanup capability plus an authorized cleanup phase at the mutation boundary; confirm the checkpoint retirement refuses a wrong expected path without mutating; confirm live-session, trustworthy-owner, and conflicting issue-lock evidence each block cleanup and that dead-PID evidence alone cannot retire a lease the control plane still holds; and confirm the new tests fail when each protection is stripped. Re-run the focused issue-970 suite and adjacent suites from a branches worktree, compare the full-suite failing ids against the pre-change baseline, and post a formal verdict pinned to the exact head above. Do not merge. ``` WHAT_HAPPENED: Author remediation of review 644 landed as commit c763161702695ba7c4dff49882105299097e46cc on the existing branch fix/issue-970-safely-resolve-missing-worktrees. No second pull request was created; PR #972 advanced in place and still closes #970. Blocker-by-blocker mapping follows. - **B1 - live ownership and status revalidation.** Production code: `missing_worktree_reconcile.py` (`resolve_missing_worktree_binding`, new `read_live_safety_state`, `compare_safety_state`, `_safety_snapshot`, `SAFETY_SNAPSHOT_FIELDS`); `control_plane_db.py` (`retire_lease_worktree_path` expected-status/session/owner-pid compare-and-swap). Correction: the audit records a normalized safety snapshot per binding, and apply re-reads the authoritative lease row, session rows, checkpoint row, and durable issue locks immediately before mutating, diffs every safety-relevant value (binding path and identity, lease id/status/session/owner pid, checkpoint path/status, live-session evidence, trustworthy ownership evidence, issue-lock state), fails closed without mutation on any change, and reclassifies from the live values rather than the snapshot; a candidate carrying no audited snapshot is refused. The unguarded secondary `retire_lease_worktree_path` call that swallowed its own exception was removed. Adversarial coverage: `TestB1StaleSnapshotRevalidation` (7 tests) including the reviewer's exact probe (released at audit, re-activated with a live pid before apply), session-id change, owner-pid change, stored-path change, a live session appearing after audit, a missing audited snapshot, and proof that revalidation reads the DB rather than the candidate. Result: 7 passed; disabling the drift check turns 6 of them red. - **B2 - server-enforced cleanup authorization.** Production code: `gitea_mcp_server.py` (`gitea_reconcile_missing_worktree_bindings`); `missing_worktree_reconcile.py` (`assess_cleanup_authorization`, `_authorization_valid_for_apply`, `OPERATOR_AUTHORIZED_REJECTION`); `task_capability_map.py` (new reconciler-only `reconcile_missing_worktree_bindings` capability requiring `gitea.branch.delete`, added to `ROLE_EXCLUSIVE_TASKS`). Correction: a client-supplied `operator_authorized` is rejected outright at the tool before any other work and again in the module, per the #709 F1 / review 434 pattern. Apply mode now requires, together, the reconciler role, a server-evaluated `gitea.branch.delete` capability, the resolved cleanup task capability, and an active authorized cleanup phase from `audit_reconciliation_mode` - which is re-checked at the mutation boundary itself, so a forged authorization mapping cannot substitute for the gate. Dry-run remains available to any `gitea.read` profile and stays non-mutating. Existing role, repository, parity, and provenance gates are untouched. Adversarial coverage: `TestB2ServerEnforcedCleanupAuthorization` (8 tests) and `TestB2ProductionMcpBoundary` (8 tests) driving the registered tools through `mcp_server`: reviewer with `operator_authorized=true`, reviewer without cleanup capability, an author profile holding `gitea.branch.delete` but the wrong role, a correctly-profiled reconciler with no minted cleanup phase, a forged authorization mapping, non-mutating dry-run, and an authorized reconciler apply that does retire. Result: 16 passed; restoring the old client-boolean trust turns the reviewer probe red. - **B3 - expected-path compare-and-swap.** Production code: `control_plane_db.py` (`retire_session_checkpoint_worktree_path`, mirrored in `retire_lease_worktree_path`, new `_realpath_or_raw` helper). Correction: `expected_path` is now mandatory and enforced; the row is selected, its stored realpath compared, an optional expected status compared, and the UPDATE keyed on the exact stored path with a rowcount check, so a path moved, replaced, or concurrently changed after audit is refused without mutation. Unknown rows and ambiguous session selectors are refused; an already-empty binding returns a non-mutating idempotent outcome instead of falsely reporting a retirement. Adversarial coverage: `TestB3ExpectedPathCompareAndSwap` (8 tests) including the reviewer's exact probe (wrong `expected_path` previously returned `retired=true`), missing `expected_path`, unknown row, exact-path success plus idempotent repeat, and the lease-side status and session mismatches. Result: 8 passed; removing the checkpoint path comparison turns the reviewer probe red. - **B4 - live-session and issue-lock evidence.** Production code: `missing_worktree_reconcile.py` (`collect_session_evidence`, `collect_issue_lock_bindings`, `find_conflicting_issue_lock`, `classify_worktree_binding`, `TERMINAL_LEASE_STATUSES`, `SESSION_HEARTBEAT_STALE_SECONDS`). Correction: `session_active` is now derived from the control-plane sessions table instead of never being set, along two axes - genuine liveness (recorded active, pid not dead, heartbeat fresh, reusing the rule from `restart_coordinator._classify_session`) and weaker recorded ownership. A non-terminal lease protects its binding regardless of recorded-pid liveness, so dead-pid evidence alone can no longer retire a lease the control plane still holds. The previously unused `issue_lock_store` is now read: a live durable issue lock binding the path or branch blocks cleanup, and locks whose own paths are missing are reported in a separate dimension for release through their own lifecycle rather than retired here. Precedence is explicit and documented: an explicitly terminal lease outranks a merely recorded-active session row, because session rows are opened on assignment and never closed on release - treating one as protective would make every released lease permanently unretireable and leave the worktrees dimension degraded forever, which is the condition #970 exists to clear. Adversarial coverage: `TestB4OwnershipEvidence` (9 tests): active lease with a dead recorded pid, `session_active` actually populated, a live session blocking a released lease, trustworthy owner evidence without a live process, a released lease outranking a lingering session row, a checkpoint binding protected by its owning session, a conflicting issue lock blocking cleanup, a missing-path lock reported but never retired, and a dead-owner lock not over-blocking an unrelated binding. Result: 9 passed. - **B5 - adversarial regression coverage.** Production code exercised, not mocked: the registered MCP tools via `mcp_server` (which execs `gitea_mcp_server.py`), the real `ControlPlaneDB` against a temporary SQLite control plane, the real `audit_reconciliation_mode` cleanup gate, the real `issue_lock_store` reader via its own lock-directory environment variable, and the real `task_capability_map`. Coverage spans lease status change between audit and apply, lease ownership or session change, binding and checkpoint path change, expected-path mismatch, concurrent recreation, unauthorized caller with `operator_authorized=true`, wrong profile and missing cleanup capability, live-session evidence, trustworthy owner evidence, active or conflicting issue lock, non-mutating dry-run, exact stale binding only retired, unrelated worktrees and git metadata preserved, repeated execution safe and idempotent, valid cleanup resolving the worktrees dimension, and production tool registration. Result: 47 passed. Mutation-tested: disabling the B1 drift check produced 6 failures, restoring the B3 checkpoint bug produced 1 failure, and re-honouring the client `operator_authorized` produced 1 failure - each protection is load-bearing. All original issue 970 acceptance criteria are preserved, including the distinctions between deleted paths, moved paths, unavailable hosts or mounts, transient filesystem failures, live ownership, and concurrent recreation. Scope was held to review 644: allocator queue ranking, the earlier abandon-audit same-owner anomaly, issue 711, issue 969, PR 971, unrelated refactoring, and manual database repair were all left untouched, and no control-plane row was edited by hand. WHY: Review 644 established that the workflow could mutate control-plane state on evidence it had not revalidated, on authorization a client could assert for itself, and through a checkpoint update that ignored the path it claimed to be retiring, while the tests would have stayed green if those protections were deleted. Each correction closes the specific failure path the reviewer demonstrated, and the new tests fail when the corresponding protection is removed. RELATED_PRS: PR #972 (this pull request, the only pull request for issue 970; no second pull request was created). ISSUE: 970 HEAD_SHA: c763161702695ba7c4dff49882105299097e46cc REVIEW_STATUS: Review 644 (REQUEST_CHANGES by sysadmin) was submitted at the old head 3f584352df279629d80d2aaa0be4e6dd66c56fc9 and now reports stale=true with author_pushed_after_request_changes=true. It is not a verdict on this remediation. No verdict exists at the new head; approval_visible is false and approval_at_current_head is false. MERGE_READY: false BLOCKERS: None known to the author. A fresh independent reviewer verdict at head c763161702695ba7c4dff49882105299097e46cc is required before any merge consideration. VALIDATION: Focused suite tests/test_issue_970_missing_worktree_reconcile.py 47 passed. Adjacent suites (task capability role invariants, audit reconciliation mode, control plane DB, lease lifecycle, reconciler cleanup integration, delete-branch capability, restart coordinator, bootstrap lock contract) 252 passed with 93 subtests. Full suite from the branches worktree 28 failed / 6000 passed / 6 skipped; the pre-change baseline built from a detached worktree at 3f584352df279629d80d2aaa0be4e6dd66c56fc9 gave 28 failed / 5960 passed, and a sorted diff of the two failing-id lists is empty - the failing set is identical and pre-existing, and it includes the tests/test_issue_956_threat_model.py anchor-resolution test, which already failed at the reviewed head and was left untouched as outside review 644. Final diff reviewed against master: six files, all changes scoped to issue 970 and review 644; the shared-file hunks are additive capability entries only. No unrelated changes.
