#753 added the dead-session author-lock recovery assessor, but no sanctioned
recovery could ever reach the lock write. A dead-session lock is by construction
a lock for work that already has an open PR, and the #400 duplicate-work gate
blocked unconditionally on any linked open PR. gitea_lock_issue computed
recovery_sanctioned, then discarded it one gate later:
open PR #750 already covers issue #749 (fail closed)
Because the recovered lock was never persisted, it stayed non-live, so
_prove_author_ownership_for_pr found no live author lock and
gitea_update_pr_branch_by_merge failed closed too. Both blockers had a single
cause, so only the first one is fixed here.
issue_lock_recovery.owning_pr_recovery_evidence distils a granted assessment
into the minimum evidence the duplicate gate needs: issue, branch, owning PR
number, and head. It returns None unless the outcome is RECOVERY_SANCTIONED and
the assessment's own evidence agrees that local head == remote head == PR head,
so a partial or hand-built assessment cannot authorize anything.
The duplicate gate takes that evidence and re-checks every element against the
live PR list it was handed: exactly one linked open PR, matching number, head
branch, head SHA, and locked branch. Only that exact self-owned PR is exempt.
A different PR, several linked PRs, a different branch or head, or evidence for
another issue all keep failing closed, with a diagnostic naming which element
disagreed. The competing-branch, claim-lease and commit/push/create_pr arms are
untouched, and with no evidence the gate behaves exactly as before.
Ownership proof needed no change: once the recovered lock persists under the
live session pid, _prove_author_ownership_for_pr matches it as before.
Out of scope: the PHASE_COMMIT/PHASE_PUSH/PHASE_CREATE_PR rechecks still block
on a linked open PR for every author, recovered or not. That is pre-existing
#400 behavior, unrelated to lock recovery, and #755 does not cover it.
Tests
- tests/test_issue_755_owning_pr_recovery.py (new, 31 tests) drives the real
mcp_server.gitea_lock_issue handler, not only the pure assessor: sanctioned
recovery relocks, persists a live lease with truthful dead_session_recovery
provenance, and satisfies _prove_author_ownership_for_pr; competing PR,
multiple linked PRs, mismatched head/branch/worktree, dirty worktree, live
prior pid, and a fresh claim with no prior lock all stay blocked.
- Neutralizing owning_pr_recovery_evidence regresses all three success tests to
the exact production error above, so the coverage is load-bearing.
- Focused suites (755, 753, duplicate gates, lock registration, provenance) —
102 passed.

A durable author issue lock records the PID of the MCP session that took it.
When that process exits, assess_lock_freshness marks the lock stale (live=False)
even while its lease is still within TTL, so every ownership check that needs a
live lock fails closed -- including gitea_update_pr_branch_by_merge.
Re-taking the lock was unreachable for real work. assess_issue_lock_worktree
requires the worktree to be base-equivalent to master/main/dev, and a branch
that already carries commits is ahead of its base by construction. The existing
assess_expired_lock_reclaim affordance does not apply either: it is only
consulted once the lease has expired, so a dead PID under an unexpired lease
never reaches it. assess_own_branch_adoption already speaks of "lock recovery",
but it runs after the base-equivalence gate and so was never reached.
This adds issue_lock_recovery, a pure assessor that grants a narrow waiver only
when every element of durable ownership still matches exactly and the recorded
process is demonstrably dead: same remote/org/repo/issue, same branch (and the
worktree actually on it), same registered worktree, clean worktree, local head
== remote head == open PR head, same claimant identity/profile, no competing
live lock or lease, and no ambiguous branch claims. A malformed or incomplete
lock record can never prove ownership.
The waiver suppresses base-equivalence and nothing else. Cleanliness and every
other precondition still apply, and brand-new issue claims keep the full
requirement. A refused assessment never raises: it withholds the waiver and
lets the pre-existing guard fail closed exactly as before, so recovery can only
ever add permission, never remove a guard. Refusal reasons are appended to the
block message so a caller sees the exact missing evidence.
A completed recovery is recorded on the lock as dead_session_recovery with the
prior and replacement session PIDs, heads, and claimant, so the takeover is
auditable and never looks like an original claim. Rebinding sets the live
session PID, so the recovered lock satisfies verify_lock_for_mutation and the
downstream PR update paths.
Validation:

`gitea_assess_pr_sync_status` could permanently block a merge-ready PR whose
head commit had no status contexts.
Gitea's combined commit-status endpoint reports `state: pending` both when a
check is executing and when the status-context collection is empty. The
wrapper took that `state` verbatim, and `checks_required` defaulted to True
with no production path ever setting it, so "no CI configured" was
indistinguishable from "CI is running" and waiting could never resolve it.
Root cause spans the whole dataflow, not one call site:
* the wrapper read only the combined `state` and never counted contexts;
its `checks_status="none"` fallback was unreachable for any truthy state
* `pr_sync_status.assess_pr_sync_status` defaulted `checks_required=True`
* the MCP wrapper exposed no derived `checks_required` and never passed one
* the branch-protection reader fetched the payload carrying
`enable_status_check` / `status_check_contexts` and discarded both
Changes:
* `pr_sync_status.py`: add `classify_commit_checks` plus explicit
CHECKS_* classifications (success / failure / pending / none /
not_required / missing_required / unknown). The combined state is
recorded for observability but is never evidence that CI is executing.
Aggregation is fail-closed and newest-wins per context.
* `pr_sync_status.py`: rewrite the merge_now checks gate to consume the
derived `checks_required`, distinguish the new classifications with
precise blocker reasons, and fail closed on unrecognized vocabulary.
The previous gate let any value outside its fixed vocabulary fall
through to merge_now.
* `gitea_mcp_server.py`: add `_branch_protection_policy` deriving both the
current-base rule and the status-check requirement from one live read;
`_branch_protection_requires_current_base` is retained as a thin
accessor with unchanged semantics. Add `_commit_checks_snapshot` which
returns the context collection alongside the combined state.
* `gitea_mcp_server.py`: wire the derived `checks_required` into the
production assessment path and report `checks_evidence`.
`checks_required` is always derived from live evidence and is deliberately
not a caller-supplied input, so no session can declare checks optional
without proof. Live classification also outranks a caller-supplied
`checks_status`, which can no longer mask a real required-check failure.
An unreadable protection policy or status collection stays fail-closed.
Approval, current-head, current-base, mergeability, conflict, role, lease
and merge-authorization gates are unchanged.
Tests: `tests/test_issue_751_checks_assessor.py` (40 tests).

Provide a narrow phase-scoped bootstrap so gitea_create_issue can run from
a clean canonical control checkout when no issue number—and therefore no
issue-backed worktree—can exist yet. Dirty roots, non-base branches, base
races, foreign workspaces, and all post-creation author mutations remain
fail-closed under the ordinary branches-only guard.
Closes#749.
Reviewer and merger PR leases minted a fixed 120-minute expiry (#407 AC6/AC7)
and derived staleness from two further activity bands: stale at 30 minutes,
reclaimable at 60. A session that died — daemon crash, transport flap, client
restart — therefore kept a PR blocked for an hour before anyone could reclaim
it, and two hours before manual cleanup was sanctioned. #718 records the
resulting deadlock: a merge stalled behind a reviewer lease that had stopped
being live long before it stopped being authoritative.
The flaw was using a long fixed expiry as a proxy for "the owner is probably
still alive" instead of making the owner continuously prove liveness.
Sliding window
--------------
`LEASE_TTL_MINUTES = 10` now governs acquisition, and every write of the lease
marker re-derives `expires_at` from the moment of the write, so each heartbeat
slides the window forward. An actively heartbeating session is never evicted
and has no maximum lifetime; a dead one releases its hold within one TTL.
`LEASE_RENEWAL_MINUTES` is named separately from the acquisition TTL. Renewal
previously had no seam at all: the heartbeat slid the expiry only as a side
effect of re-defaulting the acquisition constant, so the two durations could
not be reasoned about or tuned independently. `format_lease_body` now takes an
explicit `ttl_minutes`, and the heartbeat passes the renewal window rather than
relying on that default.
Merger leases acquire through the same lease-body formatter, so they inherit
the identical window by construction rather than by a parallel constant.
Removal of the reclaim tier
---------------------------
`classify_lease_freshness` no longer returns `reclaimable`. Beyond being an
extra waiting tier, that band is unreachable under a sliding TTL: a heartbeat
stamps `last_activity` and `expires_at` together, so a lease idle for a full
TTL is necessarily already expired. Expiry is now the only takeover gate.
No reclaim path is lost. `find_active_reviewer_lease` already ignores expired
markers, so an expired foreign lease never gated acquisition; and the
`foreign_expired` classification carries the same
`NEXT_ACTION_RELEASE_EXPIRED_LEASE` the retired `foreign_reclaimable` did. The
two updated tests in `test_reviewer_pr_lease.py` assert exactly that: the
classification label changes, the sanctioned next action does not.
`STALE_WARNING_MINUTES` drops to 5 — half the window — so the warning still
fires while the owner can heartbeat and recover.
Diagnostics
-----------
Adds `lease_seconds_remaining`, and the heartbeat tool now returns
`ttl_minutes`, `expires_at`, and `seconds_remaining`, so an operator can
distinguish "held and live" from "held and dying" instead of only seeing that
a lease exists. All additions are additive; no existing key changed.
Also removes `pr_work_lease.DEFAULT_REVIEWER_LEASE_TTL_MINUTES`, a duplicate of
the reviewer TTL with no readers anywhere in the tree, which could only drift.
Legacy markers minted under the old 120-minute TTL still parse and are judged
against their own recorded `expires_at`, so no lease is retroactively expired
by this change.
Full suite: 3425 passed, 6 skipped, 2 failed. Both failures
(`test_issue_702_review_findings_f1_f6`, `test_reconciler_supersession_close`)

#706 introduced the immutable `canonical_repository_root` and #739/#740 routed
three consumption paths through it. The paths #740 left behind all shared one
shape: the *filesystem* guards had been migrated to the canonical root, but
*repository identity* still bottomed out in `_local_git_remote_url`, which ran
`git remote get-url` with `cwd=PROJECT_ROOT` — always the Gitea-Tools install
checkout. The two halves of a single assessment therefore described two
different repositories.
For a namespace bound to another repository this inverts the guards rather than
merely weakening them: an operation naming the genuinely bound target is
rejected, while one naming Gitea-Tools is accepted.
Central helper
--------------
Adds `_canonical_local_git_root()` as the single place a target-repository root
is resolved: the configured canonical root when one is declared, else
`PROJECT_ROOT`. A configured-but-invalid root is never silently replaced by the
install checkout. Single-repository behaviour is byte-for-byte unchanged.
Defects fixed
-------------
* `_local_git_remote_url` now runs in the canonical target root, which corrects
every downstream identity consumer at once (`_resolve`, the #530 remote/repo
guard, the anti-stomp org/repo fill, `_workspace_repository_slug`).
* `_verify_role_mutation_workspace` omitted `configured_canonical_root`, so the
#274 branches-only / worktree-membership guards validated
`Gitea-Tools/branches/` instead of the bound target. It now threads the root
exactly as `_resolve_namespace_mutation_context` does.
* `_resolve` derived omitted coordinates by looking a remote up *by name*. A
target checkout commonly names its remote `origin` rather than `prgs`, so the
lookup returned None and the coordinates fell through to the remote-wide
default target — an unrelated repository. It now prefers
`_canonical_repository_slug`, which probes candidate remote names.
* Explicit `org`/`repo` short-circuit the #530 match check, so caller
coordinates bypassed validation entirely. They may now only *confirm* a
canonical binding, never override it, and fail closed in both directions.
* Reconciler ancestry, fetch, worktree-inventory and cleanup call sites, the
author worktree derivation in `gitea_lock_issue`/`gitea_create_pr`, and the
`control_clean` porcelain probe now use the canonical target root.
* `gitea_config`: v2-`environments` silently *dropped* `canonical_repository_root`
during flattening, so such a namespace fell back to the install root — a
fail-open. It is now validated and propagated. The v1 path validates it too,
so all three loaders behave identically.
Preserved as installation-scoped
--------------------------------
Server parity (`master_parity_gate`), workflow/schema/skill loading, self-code
hashing and stale-runtime detection, and `mirror_refs.sh` lookup remain anchored
to `PROJECT_ROOT`. The `server_implementation` vs `target_repository` parity
dimensions from #740 stay separately labelled, and only the server dimension
gates mutations.
Tests
-----
`tests/test_issue_741_canonical_root_consumers.py` (51 tests, 52 subtests) drives
a role-by-operation matrix over author/reviewer/merger/reconciler against:
correct cross-repository target, wrong repository, wrong worktree, explicit
matching and mismatched coordinates, missing/invalid canonical root, immutable
first-bind, and request-override attempts — plus both cross-repository
directions and all three config loaders. Real git repositories, no network, no
branch deletion, no merge.
The module reinstalls the genuine `_local_git_remote_url` per test: an autouse
conftest fixture permanently reassigns it to a working-directory-independent
stub, which is precisely the behaviour under test.
Full suite: 3408 passed, 6 skipped, 2 failed. Both failures
(`test_issue_702_review_findings_f1_f6`, `test_reconciler_supersession_close`)

Root cause (confirmed on PR #740, session 33780-7168cbeeba58, marker 12354):
merger_lease_adoption.SANCTIONED_PROVENANCE_SOURCES already contained
SOURCE_ACQUIRE_MERGER, so the membership check passed, but
is_sanctioned_session_lease() branched only for SOURCE_ADOPT and for
{SOURCE_ACQUIRE, SOURCE_HEARTBEAT} and fell through to `return False` for a
lease minted by gitea_acquire_merger_pr_lease. assess_mutation_lease_gate()
therefore appended "in-session lease lacks sanctioned provenance" and
gitea_merge_pr fail-closed on the merger's own freshly acquired lease.
describe_session_lease_proof() likewise had no branch for that source and
reported the lease as lease_proof_kind=unsanctioned. Separately, no
merger-role owner-session operation existed to end that lease, so a failed
merger lease could only expire.
A. Acquired merger provenance
is_sanctioned_session_lease() now accepts SOURCE_ACQUIRE_MERGER, but only via
the new assess_acquired_merger_lease_integrity(), which fails closed unless
the in-session record is complete and self-consistent: comment marker present
and matching between provenance and session, non-empty session id, holder
identity, merger profile, repository, valid PR number, and a normalized
40-hex candidate_head. describe_session_lease_proof() reports the explicit
kind sanctioned_acquire_merger. Manual _SESSION_LEASE seeding, forged or
incomplete records, mismatched fields, and unknown provenance all remain
rejected; reviewer-acquire, reviewer-heartbeat, and merger-adoption paths are
untouched.
B. Merger owner-session finalization
New native tool gitea_release_merger_pr_lease terminally releases or abandons
a merger's own comment-backed lease when the merge does not occur. It is
merger-only (gitea.read + gitea.pr.comment + gitea.pr.merge; reviewer profiles
lack pr.merge) with an explicit capability-map task release_merger_pr_lease /
gitea_release_merger_pr_lease bound to gitea.pr.comment + role merger, and it
is listed as role-exclusive in the resolver. assess_merger_lease_finalization()
verifies exact session ownership, repository, PR, candidate head vs live head,
profile, identity, marker presence on the thread, and the native runtime token
fingerprint recorded at acquisition; foreign-session release, reviewer-profile
use, and any mismatch fail closed. Finalization appends a terminal lease marker
and never edits or deletes ledger history; an already-terminal lease returns
already_terminal and posts nothing. The PR, approval, decision lock, branch,
and worktree are all preserved. gitea_release_reviewer_pr_lease is unchanged
and is not repurposed for merger sessions.
"abandoned" is added to reviewer_pr_lease._TERMINAL_PHASES; without it an
abandoned marker would fall through the generic non-empty phase branch and
keep re-arming the lease as active.
Tests: new tests/test_merger_lease_finalization.py (38 tests, 11 subtests)
covers all twelve acceptance criteria — provenance sanctioning, explicit proof
kind, merge-gate acceptance, manual-seed and unknown-provenance rejection,
profile/role/session/head/repository/fingerprint mismatches, owner release,
foreign-session refusal, reviewer refusal, append-only idempotent
finalization, no surviving lease after finalization, and no regression in
adoption or reviewer-lease behavior. The defect was reproduced on clean
baseline a8d2087 first (is_sanctioned=False, proof_kind=unsanctioned, no
finalization path).
Validation: targeted lease/capability suites 272 passed. Full suite
3305 passed, 6 skipped, 2 failed — both failures
(test_issue_702_review_findings_f1_f6 F1 recovery, reconciler supersession

this change.

#706 routed the #274 filesystem guards and the session repository slug through
the configured canonical_repository_root. Three consumption paths were left
deriving from the Gitea-Tools installation checkout.
F1 — gitea_get_runtime_context did not normalize its `remote` argument, while
gitea_whoami did. On a prgs-hosted namespace whose first native call was the
runtime-context path, the 'dadeschools' argument default was pinned: identity
resolved against the wrong host, and because first-bind is first-write-wins a
later correct gitea_whoami(remote="prgs") could not repair the binding. It now
calls _effective_remote before any host lookup, identity resolution, or session
seeding. Explicit remotes pass through untouched and a dadeschools-hosted
profile still resolves to dadeschools.
F2 — _delete_branch_repository_binding_block derived its expected slug from
_workspace_repository_slug, which reads _local_git_remote_url in PROJECT_ROOT
(always Gitea-Tools). For a cross-repository namespace this inverted the guard:
the genuinely bound target was rejected and Gitea-Tools was accepted. The
canonical-root branch already present in _trusted_session_repository is
extracted as _canonical_repository_slug and shared by both call sites. A
configured-but-unresolvable root now fails closed instead of falling back to
the installation identity; unconfigured namespaces keep the install-derived
default unchanged.
F3 — gitea_assess_master_parity measures Gitea-Tools server implementation
parity only. That is intentional and is preserved: startup_head, current_head,
in_parity, stale, and restart_required keep their existing meaning and values,
and only the server dimension gates mutations. Two separately labelled
dimensions are added — server_implementation (installation root and commit) and
target_repository (canonical root, repository slug, checkout head, last-known
remote master head, staleness) — so cross-repository commissioning evidence can
distinguish them. The target assessment makes no network call: the remote side
is read from the existing remote-tracking ref, and an unfetched target is
reported indeterminate rather than guessed at.
Verified intentional and left unchanged: the #274 workspace-membership,
author-mutation-worktree, and branches-only guards already validate against the
configured canonical root; explicit org/repo may confirm but never authorize a
binding; and the four-role repository-specific configuration surface already
passes audit and bind-time validation with a wrong root failing closed.
Tests: 31 new cases in tests/test_cross_repo_canonical_consumption.py using
real git repositories and no network. Full suite 3298 passed / 6 skipped
against a clean-baseline 3267; the 2 failures

Addresses REQUEST_CHANGES review 457 on PR #736.
Root cause: _trusted_session_repository derived the session org/repository
solely from _workspace_repository_slug -> _local_git_remote_url, which runs
`git remote get-url` in PROJECT_ROOT (the Gitea-Tools install checkout). A
cross-repository namespace with a configured canonical_repository_root then
pinned the Gitea-Tools identity while #274 filesystem membership bound the
external target, so _enforce_canonical_repository_root failed closed on a
self-inflicted identity mismatch and the mcp-control-plane / eagenda
namespaces stayed blocked end-to-end.
Fix: when a canonical_repository_root is configured (env over profile) and
passes existence / git-toplevel / resolvable-remote-identity validation, the
session repository slug is derived from repository_identity_slug(configured
root) instead of the install remote. The derived identity is still authorized
by the profile allowed_repositories allowlist (never self-authorizing); the
canonical filesystem root and org/repo identity remain immutable for the
session; invalid / non-git / unresolvable / unallowlisted / forged / drift
cases fail closed; unconfigured single-repo Gitea-Tools namespaces keep the
install-derived slug unchanged.
Tests: new tests/test_issue_706_f1_seed_identity_integration.py drives the
real _seed_session_context -> _enforce_canonical_repository_root path with two
real temporary git repositories (install=Gitea-Tools, configured target=
mcp-control-plane): env + profile config, reviewer + merger role kinds, and
fail-closed cases (nonexistent / non-git / unallowlisted / forged identity
drift). Reproduces the F1 block before the fix; green after.

Session-bound author mutations (create_issue, lock_issue, create_pr, etc.)
called verify_preflight_purity without org/repo, so anti-stomp filled the
remote-wide REMOTES default (prgs → Timesheet) and false-positived wrong_repo
against a Gitea-Tools checkout even when callers passed explicit coordinates.
Mirror _resolve: prefer workspace-derived identity for omitted coordinates on
session-bound tasks; keep delete_branch's explicit-target contract (#733).
Also forward org/repo at author mutation call sites. Add cross-repo regression
coverage. Do not change REMOTES["prgs"]["repo"].
The MCP server derived the canonical repository root from the install
checkout the server script lives in (PROJECT_ROOT), so any namespace that
ran the server against an external repository (e.g. eagenda-author, or the
mcp-control-plane reviewer/merger namespaces) failed every mutation: the
branches-only / worktree-membership guards (#274) compared the task
workspace against the Gitea-Tools .git directory it can never belong to.
Separate the two concepts:
- PROJECT_ROOT stays the immutable code/install root.
- A new, optional, namespace-scoped canonical_repository_root binds the
session to the working root of the target repository.
Implementation:
- canonical_repository_root.py: resolve the binding from profile/env
(GITEA_CANONICAL_REPOSITORY_ROOT overrides the profile field), validate
existence + git identity, fail closed on missing/conflicting/forged
bindings. Preserves the single-repo default when unconfigured.
- session_context_binding.py: pin canonical_repository_root into the
immutable #714 session context; drift fails closed.
- namespace_workspace_binding.py: route the configured target root through
resolve_namespace_mutation_context so #274 / membership guards evaluate
against the target repository.
- gitea_mcp_server.py: seed + enforce the binding in the mutation preflight
(both purity-order and FORCE_PRODUCTION_GUARDS paths); validate repository
identity and git common-directory membership.
- gitea_config.py: validate the optional absolute-path profile field.
- gitea_auth.py: surface the config-sourced field through get_profile.
No weakening of root-checkout, remote/repository, or anti-stomp guards; the
single-repo Gitea-Tools path is unchanged.
Tests: two distinct real git repositories/worktrees prove cross-repository
bindings resolve, enforce membership, and fail closed on forged/conflicting
identity and simultaneous prgs/mdcps isolation.

gitea_delete_branch accepted explicit org/repo but did not propagate them
through the anti-stomp preflight. During a deletion targeting
Scaled-Tech-Consulting/Gitea-Tools, preflight resolved the remote-wide prgs
default (Scaled-Tech-Consulting/Timesheet) and failed closed with wrong_repo
before any deletion — because verify_preflight_purity was called without
org/repo and the shared #604 anti-stomp resolution fell back to the REMOTES
default.
Fix (delete_branch only; REMOTES untouched):
1. Forward the explicit org/repo into verify_preflight_purity so the shared
#604 anti-stomp resolution validates the *targeted* repository instead of
the remote-wide default. Explicit Scaled-Tech-Consulting/Gitea-Tools now
propagates through role/workspace verification, verify_preflight_purity,
anti-stomp repository resolution, and the final native deletion request.
2. Add a workspace-derived repository-binding gate
(_delete_branch_repository_binding_block) that validates explicit
coordinates against the immutable, workspace-aligned repository identity.
Wrong, substituted, or unverified coordinates fail closed — independent of
the anti-stomp remote/repo guard, which by the #530 contract trusts explicit
caller intent. REMOTES defaults are never consulted as an authorization
scope.
Preserved: reconciler-only ownership of gitea.branch.delete; author/reviewer/
merger denial; protected and preservation/evidence gates; missing coordinates
still fail closed via the anti-stomp default resolution.
Regression matrix (tests/test_issue_733_delete_branch_repo_forwarding.py):
Timesheet-default + explicit Gitea-Tools permits an eligible deletion and
forwards the coordinates; wrong/substituted/unverified coordinates fail closed;
author/reviewer/merger remain denied; protected and preservation branches
remain blocked; anti-stomp resolution marks explicit coordinates authoritative
and fails closed on the remote-wide default for omitted coordinates; the
task-capability and role-routing maps stay consistent.

Mutation tools (create_issue, create_pr, delete_branch, issue-lock) returned
reason_code=internal_error / retryable=false with no class, message, HTTP

collapses every non-typed exception to a fixed "Internal tool error" and drops

passwords, raw URLs/hostnames, and absolute filesystem paths all stripped;
whitespace collapsed; length-bounded) and an optional `mutation_stage`. Typed
auth/authz/network/config/http paths are unchanged and still emit no detail.
- Convert raw exceptions into typed structured errors via a safe
`gitea_reason_code` attribute contract: server raisers may self-declare a
known reason and the boundary emits it (fixed message) instead of an opaque
internal_error. Pre-flight order violations now raise `_PreflightOrderError`
(a RuntimeError subclass → preflight_order_violation).
- Add a `_mutation_stage` context manager tagging escaping exceptions with the
stage name (preflight_purity / resolve_auth / api_*), applied to
delete_branch, create_issue, create_pr.
Fail-closed identity/repo/worktree/role/permission/lock/lease/ancestry gates
are untouched; only error *reporting* changed. New suite
test_mutation_error_diagnostics.py (18 tests) pins the redaction, class capture,
stage tagging, typed conversion, and adversarial no-leak contract. Existing
boundary suite (25), core server (209), and preflight (92) suites stay green.

Remote post-merge branch deletion was blocked because the capability
resolver classified delete_branch as an author-role task while
gitea.branch.delete is granted only to prgs-reconciler. No configured
profile could satisfy both the permission gate and the role gate, so
every deletion failed closed with performed=false.
Re-home delete_branch from the author role to the reconciler role in
both single-source-of-truth maps:
- task_capability_map.TASK_CAPABILITY_MAP["delete_branch"].role
- role_session_router: TASK_REQUIRED_ROLE + AUTHOR_TASKS/RECONCILER_TASKS
resolve_task_capability("delete_branch") now resolves to prgs-reconciler.
In gitea_delete_branch, the reconciler is now the delete-capable role and
performs raw deletion through the existing reconciliation-cleanup-phase
authorization gate (operator approval + safe_to_delete proof) plus the
preservation/protected guards; the prior reconciler->cleanup redirect is
removed as it would orphan that guarded flow. Author, reviewer, and
merger stay denied by the permission gate and the required-role gate.
gitea_cleanup_merged_pr_branch remains a separate reconciler-owned path
with independent merged/ancestry/ownership verification.
Tests: reconciler resolves + performs eligible deletion; author/reviewer/
merger denied even when holding the permission; protected/preservation
branches remain fail-closed; both role maps asserted in agreement.
Updated pre-existing tests that encoded the superseded author-delete /
#687 reconciler-redirect contract. Full suite: 3190 passed, 6 skipped,
1 pre-existing unrelated failure (test_issue_702 create_pr stale-binding).

_verify_role_mutation_workspace dropped org/repo, so anti-stomp resolved bare
remote=prgs to Timesheet and failed closed wrong_repo on Gitea-Tools. Forward
explicit org/repo for merger/reviewer lease acquire, adopt, review, merge, and
lease release. Add regression for merger acquire forwarding.
Fixes#718
Refs #723
gitea_acquire_merger_pr_lease previously continued when GET /pulls returned
an empty head SHA. Fail closed so exact-head scoping never proceeds with an
unresolvable live head. Add regression coverage for empty head payloads.
Fixes#718
Refs #723
Prevent approved PRs from stalling when master advances. Add
gitea_assess_pr_sync_status and gitea_update_pr_branch_by_merge with
head/base pinning, author-only updates, conflict handoff, and approval
invalidation after head changes. Wire task capability map, sequential
controller routing in review-merge workflow, and hermetic AC tests.
Harden gitea_acquire_merger_pr_lease with required candidate_head, live-head
match, and fail-closed POST handling. Add capability-map aliases for reviewer
and merger lease acquire/adopt. Make unknown tasks return structured
unknown_task (no ValueError escape). Expand tests for roles, head scoping,
aliases, and unknown_task.
Closes#718. Addresses #723 resolver unknown_task and lease task mapping.
This implements the native merger lease acquisition tool to allow a merger session to acquire its own lease when a reviewer lease does not exist or has expired, unblocking #679 adoption.
Stale-runtime detection remains fail-closed, but gitea_resolve_task_capability
must never touch mcp_config.json, spawn recovery threads, or call os._exit.
- Remove _trigger_mcp_auto_restart from the read-only diagnostics path
- Return blocker_kind=runtime_reconnect_required with mutation_performed=false
- Keep exact_safe_next_action pointing at IDE/client reconnect when stale
- Add regression suite across author/reviewer/merger/reconciler profiles
Terminal review-decision ledgers are recovery-critical provenance, not
disposable session cache. A generic four-hour TTL previously made
fresh_review_on_current_head_allowed unreachable after age expiry on open
PRs (PR #616 / review 443 reproduction).
- Classify KIND_DECISION_LOCK as RECOVERY_CRITICAL so load/mark_final work
after >4h without hand-editing session-state files
- Stamp kind + recovery_critical on save for compatibility
- Add inspect_state_envelope so assessment reports on-disk evidence instead
of silent "no lock" when TTL would hide non-critical kinds
- Surface disk_inspect on stale decision-lock cleanup assessment
Preserves same-head #332 hard-stop, #620 head-scoped fresh review, #594
moot cleanup, and #709 irrecoverable authorization (no ordinary-profile
permission grant).
Require branch-scoped post-delete not-found (not generic/repo/host 404),
emit consistent top-level cleanup fields, fail closed on ownership inventory
errors, never auto-reclaim expired control-plane leases, include active
comment-backed reviewer leases, apply the same gates to reconcile_merged_cleanups,
and match ownership with normalized host identity.
Require authoritative not-found readback after merged-PR branch DELETE, and
block cleanup when active author/reviewer/merger/controller/reconciler
session, lease, or worktree-binding ownership still uses the target branch.
Close the #714 remediation gap left at 943d402 where env-only mutation
profiles, REMOTES Timesheet defaults treated as explicit caller input, and
machine-dependent Git remotes produced false greens.
- Fail closed when mutations lack a config-backed profile with non-empty
allowed_repositories; env ops cannot invent mutation authority.
- Preserve omitted-vs-explicit org/repo provenance through the mutation
gate; omitted targets bind to the verified workspace repository.
- Prefer workspace-aligned Git remotes over historical Timesheet defaults
in MCP _resolve and CLI resolve_remote.
- Centralize deterministic config-backed mutation fixtures; migrate
mutation tests off env-only authority without weakening security
assertions.

The independent review reproduced a real hole: the production first-bind path
never pinned repository/org, so the drift checks it feeds were skipped.
Root cause
----------
gitea_whoami, gitea_get_runtime_context, gitea_resolve_task_capability and
gitea_activate_profile all seeded the session context without repository or
org. First-bind-wins then made the mutation gate's later seed a no-op, and
assess_session_context only compares repository/org when the bound fields are
non-null. Result, reproduced in production order with the real REMOTES:
after whoami: repository=None org=None
same-host repo=Other-Tools -> NOT BLOCKED
same-host org=Other-Org -> NOT BLOCKED
cross-host -> blocked (this part always worked)
Binding REMOTES defaults would not fix it: REMOTES['prgs'].repo is 'Timesheet'
(a default *target*, not an authorization scope, see #530), so pinning it fails
closed on every legitimate Gitea-Tools mutation. There was no trusted source
for repository scope, so this adds one.
Design
------
- New optional profile field `allowed_repositories`: canonical owner/repository
slugs. An authorization boundary, never the binding itself. Config-only —
no env var can widen or forge it.
- The session repository is derived from the verified, workspace-aligned git
remote, never from caller-supplied org/repo, and validated against that
allowlist. The session binds immutably to exactly one canonical slug; org is
derived from it. A profile authorizing several repositories still binds to
the single verified one.
- Every first-bind entry point now pins the same complete context. Activation
rejects an unauthorized/unverifiable workspace. Mutations fail closed when
repository/org is unverified, and a tool-level org/repo override that
disagrees with the binding is rejected before the write.
- A mutation request can no longer establish, complete, or replace the binding
(it previously seeded from `org or REMOTES[...]`, i.e. caller-controlled).
- Enforcement is opt-in per profile: a profile without the field keeps prior
behaviour, so existing static-profile namespaces stay functional.
First-bind-wins, immutability, the RLock, profile isolation, host/identity
validation and the private pytest-only reset are unchanged.
gitea_auth.get_profile() built an explicit whitelist dict and silently dropped
`allowed_repositories`; the new integration tests caught that the scope was
never enforced through the real path.
Tests
-----
New tests/test_issue_714_production_first_bind.py drives the real entry points
in production order rather than constructing _SessionContext directly. Covers
complete first bind via each entry point, same-host repo/org drift, Timesheet
and other-repo/other-org rejection, unverified and unauthorized workspaces,
caller values unable to establish the binding, concurrent init selecting one
repository, and the PR #715 author path staying functional. Mutation-verified:
disabling trusted derivation, override validation, the scope check, or the
get_profile passthrough each fails these tests (9/8/4/5 failures).
No security assertion was weakened, removed, skipped, or rewritten.

Address formal review 438 REQUEST_CHANGES on PR #710 (F6/F7/F8).
F6 — HMAC key-version validation fails closed:
- verify_authorization_artifact validates key_version BEFORE any MAC work, so an
attacker-chosen version can never select the signing key.
- Require exactly one nonempty, well-formed key-version field; missing, empty,
unknown, malformed, duplicated (including identical-valued and nested
aliases), and mismatched versions all fail. No versionless legacy fallback.
- Artifact version must equal the configured active version; production now
requires GITEA_IRRECOVERABLE_AUTH_HMAC_KEY_VERSION explicitly (an implicit
default made rotation ambiguous). Version stays inside the signed material.
F7 — strictly canonical incident evidence:
- Replace substring/first-match parsing with an exact schema: marker on line 1,
every field once, fixed order, no duplicate/unknown/empty/conflicting fields
in or outside the signed block. The parsed body is re-rendered and compared
for exact equality before acceptance.
- content_digest now binds the full recovery scope: repository identity, PR,
decision-lock identity, destroyed subject, recovery action, recorded and
expected head, incident issue, evidence author, minting actor, key version,
nonce and issued_at.
- Actor identity is the immutable user id with login consistency; conflicting
ids/logins and display-name-only identities fail closed. Edited comments are
rejected. The independent-author rule is preserved and enforced by stable id.
- build_canonical_incident_body is the single source of the accepted format and
refuses to emit ambiguous evidence.
F8 — archival is a prerequisite for clearing terminal evidence:
- _clear_decision_lock_for_profile no longer swallows archive failures. It
requires a successful write plus a durable read-back matching the PR/head,
and otherwise returns a structured, retry-safe failure that retains the lock
and records actionable recovery evidence.
- Fixes a latent bug the read-back exposed: the archive payload inherited the
source lock's session_profile_lock, so save_state keyed the archive under the
reviewer profile instead of the archive identity and it never read back.
Adversarial regressions added for every listed case: key-version missing/empty/
unknown/malformed/duplicate/rotation/wrong-key-after-restart, reordered fields,
duplicate identical and conflicting fields, conflicting actor ids/names,
digest-preserving substitution, decision-lock and recovery-action substitution,
cross-PR/repo/org/remote/head replay, archive exception/timeout/false/empty/
partial-readback with proof the lock survives, exactly-one permitted clear, and
retry after archive failure. No existing assertion was weakened.
Validation: focused 150 passed in three module orders; full tests/ 2809 passed,
6 skipped, 1 warning (pre-existing StarletteDeprecationWarning in
tests/test_webui_audit.py:8), 161 subtests passed.

Capability resolution and mutation gates no longer auto-switch profiles.
Session profile/remote/host/identity are bound after pin or first seed,
and drift or cross-host resolution fails closed before writes.
