Implement a sanctioned session lifecycle for post-restart reconciliation so
active session rows with dead or reused owner PIDs can be terminalized
without deleting history. Protect live owners, live leases, and live
client-managed sessions; record durable session_retired audit events; keep
cleanup idempotent under concurrent reconciles.

Two surfaces reported different provenance for one process.
`gitea_get_runtime_context` read the live environment and reported
`client_managed`; `mcp_namespace_health.classify_namespace_probe` derived
provenance from `_safe_env_summary()`, whose `SAFE_ENV_KEYS` allowlist never
contained `GITEA_CLIENT_MANAGED`, `GITEA_MCP_CLIENT_MANAGED`, or
`GITEA_SERVER_PROVENANCE`. That lookup could only ever miss, so the health
surface was structurally incapable of returning anything but `manual_launch`.
Neither model could name which client or which session owned a runtime, so a
healthy daemon serving a second client was indistinguishable from a duplicate,
and the profile-wide duplicate scan walled the whole fleet.
Introduce `mcp_worker_identity` as the one authority, splitting two claims the
old code ran together:
* launch provenance — was this hand-launched from a terminal? Answered from the
environment, which is legitimate because the launcher sets it. Preserves the
#686 wall unchanged.
* session ownership — which live client session owns this runtime now? Answered
only from a live attachment record; no environment flag can establish it.
The module provides collision-resistant worker identities
(`<llm-name>-<UTC-timestamp>-<short-sha>`), an atomic SQLite registry with
fencing epochs, heartbeat-based liveness, generation takeover that supersedes
only a non-live claimant, cohort classification, and failure scoping.
Behaviour changes:
* Registering an existing worker identity fails closed; it is never replaced,
adopted, or merged with. The caller mints a different identity instead.
* A generation held by a live session cannot be claimed by a second one. A
generation whose claimant is not live is taken over with a higher fencing
epoch, so stale ownership cannot permanently strand a healthy daemon.
* A superseded session presenting an old epoch is refused and performs no write.
* Liveness comes from heartbeat freshness; a live PID cannot resurrect an
expired record, and a dead PID withdraws liveness.
* Workers sharing a role or profile no longer trigger a profile-wide duplicate
block, provided each carries a distinct identity. Processes with no identity
evidence remain classified as duplicates, so the #686 wall still holds.
* Runtime failures are scoped to a worker identity or generation, never to a
profile or the fleet.
* Reconnect guidance no longer defaults to Codex. An unidentified client gets
host-agnostic steps; `gitea_request_mcp_reconnect(client=...)` defaults to
resolving the client from the live attachment record.
* `resolve_bound_remote` keeps a bound namespace on its remote instead of
falling through to the `dadeschools` library default.
Absence of proof is now reported as `unproven` rather than asserted as
`manual_launch`. Both still fail closed — `is_client_managed` is unchanged, so
nothing previously refused is now permitted — but remediation names the proof
that is actually missing instead of describing a terminal launch it cannot
evidence. The #686 test is updated for that vocabulary and keeps every
wall-preserving assertion.
Threat-model anchors and their citations in docs/remote-mcp/threat-model.md are
restamped for the line movement in gitea_mcp_server.py.
Tests: tests/test_issue_948_client_session_provenance.py adds 43 cases covering
Codex/Gemini/Antigravity/Claude attachment, same-client new session, cross-client
takeover after a session ends, two live conflicting sessions, stale records,
missing attachment proof, environment flags without attachment, mixed
generations, duplicate cohorts, the hardcoded-client regression, explicit PRGS
selection, default-remote host drift, cross-surface agreement, and fail-closed
handling without false reconnect loops. Synthetic identifiers throughout.

Claude-Session: https://claude.ai/code/session_01F6Vomtndpq2gSBa88Tfcwy
A required namespace absent from the connected-service inventory was never
counted as missing, because missing_namespaces was populated only while
walking connected_servers. The session therefore reported attachment_healthy
true, discovery_status namespaces_attached and error_type None while holding
no attachment proof for that namespace, and the gate text told the operator
"the host reports Connected" about a service nothing had reported Connected.
assess_connected_namespace_attachment now classifies the two conditions
apart. missing_namespaces keeps its meaning: required, Connected at the host,
absent from the session tool surface -- the actual #708 defect, still typed
mcp_connected_namespaces_missing. Required namespaces absent from the
connected inventory land in the new not_connected_namespaces list, typed
mcp_required_namespaces_not_connected, so a caller is never pointed at an
attachment recovery for a service that never connected. attachment_healthy
is false whenever any required namespace lacks attachment proof under either
condition, error_types reports every condition present so neither hides the
other, and namespace_conditions carries the per-namespace connected/attached
verdict. Evidence that disagrees with itself -- attached in the session yet
absent from the connected inventory -- is reported as contradictory and fails
closed rather than being read as proof.
attachment_gate_from_session states only what the recorded evidence supports:
the Connected wording appears solely when connected is true, the not-connected
wording when it is false, and a neutral refusal when connected status was
never recorded. Review and merge stay fail-closed in all three cases.
_record_live_namespace_attachment consumes the per-namespace verdicts instead
of pinning the session-wide error_type onto every unattached namespace and
instead of deriving health from a missing list that tracked only one of the
two conditions.
The two existing cases in test_issue_708_mcp_namespace_attachment.py declared
no required_namespaces, so they inherited a default set containing a namespace
their connected list omitted. Under the corrected rule that is a false-healthy
assertion, so each now declares the required set it actually means.
Closes#708
Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
The prior #708 slice added assess_connected_namespace_attachment() as a pure
decision function with no call site: nothing invoked it, so a session whose
role namespaces were Connected at the host but absent from the active session
tool surface still passed every mutation gate. Detection existed on paper only.
This makes it load-bearing.
Decision layer (mcp_namespace_health.py)
- assess_connected_namespace_attachment() gains secret-free telemetry
(connected/attached/required/missing counts, discovery cache hit and age,
reconnect_required, auto_attach_attempted, auto_recovered, error_type) and
reports reconnect_required, auto_recovered and startup_ordering_race.
- Startup ordering: a namespace whose connect completed after the session tool
snapshot cannot be in that snapshot, so parallel multi-role startup is
identified as its own race with the affected namespaces listed.
- attachment_gate_from_session() is a fail-closed gate keyed by
ATTACHMENT_GATED_TASKS. An unassessed namespace does not gate, matching #543
semantics, so this never fabricates a block.
- SANCTIONED_ATTACH_RECOVERY_TOOL names gitea_request_mcp_reconnect (#678) as
the only recovery.
Server wiring (gitea_mcp_server.py)
- New tool gitea_assess_mcp_namespace_attachment classifies the condition and
records a per-namespace verdict in _LIVE_NAMESPACE_ATTACHMENT.
- gitea_submit_pr_review and gitea_merge_pr now consult
_namespace_attachment_gate() alongside the existing #543 health gate, so both
fail closed while a required namespace is unattached.
- Watchdog check-in emits status only, never namespace contents.
The typed condition mcp_connected_namespaces_missing stays distinct from config
drift (#672), transport-closed (#584) and resolver EOF (#685). Recovery never
routes through direct imports, CLI or raw API mutation, profile hopping,
session-state overrides, or process kills.
Docs
- docs/mcp-namespace-health.md documents the tool arguments, startup ordering,
the fail-closed gate, and the telemetry contract.
- skills/llm-project-workflow/SKILL.md states Connected is not attached, and
that preflight proof is live tool visibility plus gitea_whoami on the role
namespace rather than host status alone.
- docs/mcp-tool-inventory.md lists the new tool.
- docs/remote-mcp/threat-model-anchors.json and threat-model.md: 21 #956 anchors
restamped for the line shift these additions caused in gitea_mcp_server.py.
Every anchor was re-derived from its recorded expect substring; none guessed.
Tests
- tests/test_issue_708_attachment_wiring.py (19 cases): typed detection, proof
mapping, reconnect-only next action, auto-attach success and failure,
reconnect rediscovery, multi-role startup ordering, telemetry including a
no-secret-leak assertion, fail-closed gate per role, unassessed and unmapped
tasks not gating, partial attachment gating only the affected role, and no
healthy verdict without attachment proof.
Verification
- tests/test_issue_708_attachment_wiring.py + test_issue_708_mcp_namespace_attachment.py: 24 passed
- namespace/session/runtime/review sweep: 427 passed, 12 subtests
- full suite head: 31 failed, 5885 passed, 6 skipped, 1047 subtests
- full suite base 17ba1ff035: 30 failed, 5862 passed, 6 skipped, 1047 subtests
- failing identifier sets match, plus tests/test_mirror_refs.py DryRunBanner,
which fails on the unmodified base in isolation and passes here: flaky, not a
regression from this branch.
- Gate proven by execution, not inspection: registering the assessment blocks
merge_pr and review_pr, and attaching the namespaces clears the block.

Addresses B1 and B2 from formal review 635 on PR #966. Both are one defect:
the seam conflated two questions that must stay separate.
recognition: "is this an identifier this system knows, and may it be
bound, pinned and recorded?"
execution: "is this entrypoint commissioned to actually serve on it?"
SUPPORTED_TRANSPORTS answered the first and was then used to answer the
second, so registering streamable-http was the same act as executing it.
With mcp.run fed the bound value, GITEA_MCP_TRANSPORT=streamable-http
reached FastMCP.run -> run_streamable_http_async and started a uvicorn
HTTP server over the whole tool surface with auth=None, no TLS and no
per-request principal. That endpoint is owned by #938 and is an explicit
non-goal of #931. B2 is why B1 was reachable: bound_transport was read
only by reporting sites, so no decision anywhere depended on it.
The fix adds an execution-authorization layer rather than removing the
identifier or mapping it to stdio, both of which would have destroyed the
seam #931 exists to create.
mcp_transport_config gains EXECUTABLE_TRANSPORTS, a strict subset of
SUPPORTED_TRANSPORTS containing only the local transport, plus
TRANSPORT_EXECUTION_OWNER recording that #938 commissions the remote
listener. assess_transport_execution returns a structured verdict:
transport, recognized, executable, allowed, blocker_kind, owner_issue,
reasons and exact_next_action.
mcp_daemon_guard gains assess_serve_authorization, which is the decision
that consumes bound_transport and is what stops it being reporting-only
metadata, and authorize_transport_execution, which enforces two ordered
boundaries: assert_transport_bound first, so an unbound runtime keeps its
pre-existing #695 failure and reason code; then execution authorization,
so a registered but uncommissioned transport is refused before any
listener exists and before any tool can dispatch. TransportExecutionError
subclasses UnsanctionedRuntimeError, so every existing fail-closed handler
still catches it while a caller that cares can distinguish the two cases.
native_runtime_status now reports executable_transports, serve_authorized
and the full serve_authorization verdict.
The entrypoint serves through authorize_transport_execution.
Net effect. stdio: unchanged, still binds and still reaches the runner.
streamable-http: still recognized, still validated, still pinned, still
recorded in decision-lock and audit provenance -- and refused at the serve
boundary with blocker transport_listener_not_commissioned naming #938.
Unregistered identifiers still fail earlier, at bind validation. Unbound
execution keeps the #695 contract. Rebind idempotence and conflict
rejection, session isolation, provenance and secret handling are untouched.
Tests: 63 in tests/test_issue_931_transport_bind_seam.py, up from 42. New
coverage proves stdio reaches the real runner; the remote identifier binds
and is recorded yet never reaches run(); no socket is bound during the
refusal, asserted with a socket.bind tripwire; the refusal names the
transport, the unmet requirement and #938; the decision genuinely consumes
bound_transport, proven by flipping only that value; no mutation is
authorized after denial; verdicts do not leak across runtimes; and the
refusal carries no credential material. Per review 635 the two file-list
scans are now globs over the production surface, and a new test asserts
there is exactly one mcp.run site and that it routes through the guard.

Closes#931.
The transport was a literal passed once at the bottom of the module,
bind_native_mcp_transport(transport="stdio"), and every guard that asks
"is this a trusted native session" resolves that question through the
value bound there. The string was a constant in the authorization chain
rather than configuration, so a remote transport had no way to be
expressed and no way to be told apart from an untrusted offline import.
mcp_transport_config becomes the single source of truth: it owns the
permitted set, the default, and the resolution of deployment
configuration (GITEA_MCP_TRANSPORT) into a validated identifier. Unset
configuration still yields stdio, so existing deployments are unchanged.
streamable-http is accepted so the bind is pluggable; standing up its
listener remains #938. sse is deliberately not registered.
bind_native_mcp_transport now resolves from configuration when no
transport argument is given, validates against that one permitted set
before writing the runtime record, and pins the result. bound_transport
is the shared accessor every transport-aware guard reads; it reports the
pinned value and never the environment, so a post-bind GITEA_MCP_TRANSPORT
change cannot move what a guard observes -- the rule already applied to
the session-state root under #695 AC2. Rebinding the same identifier is
idempotent; rebinding a different one is refused, so two guards can never
disagree within one process. assert_transport_bound fails closed before
mcp.run, so an absent or invalid bind stops the server instead of serving
tools over a transport no guard can name.
The bound identifier is now recorded in durable provenance:
mutation_provenance_fields gains bound_transport, which reaches the
decision lock through mcp_session_state.save_state and the audit records
that already spread those fields. The pre-existing transport field keeps
its trust-class values, so no durable record changes shape.
assess_transport_for_auth_mint reports the bound transport through the
same accessor; its verdict is unchanged.
#956's anchor fixture and threat model are re-anchored for the lines this
change shifts, and the two boundary claims that #931 makes false -- the
"literal stdio bind" in B1 and the stdio contract at mcp_server.py:4 --
are restated. Without this the #956 guard fails, which is what it is for.
Non-goals, untouched: the remote listener (#938), per-request principal
resolution (#932), client-managed provenance policy (#934), TLS and
remote client authentication, role capability sets, repository-binding
semantics.
Tests: tests/test_issue_931_transport_bind_seam.py, 42 tests, covering
default bind, explicit stdio, the accepted non-stdio identifier, an
unregistered identifier, no bind at all, one-value agreement across
guards, post-bind environment tampering, the durable decision-lock
record, the rebind contract, and the #695 protections that must not
regress.

Review 632 F1. `gitea_recover_incomplete_bootstrap_lock` writes the same
durable author issue lock as `gitea_recover_dirty_orphaned_issue_worktree`
but gated only on the reviewer-stop router check and the profile permission
block. Every other author state-creating mutation carries a third gate,
`_namespace_mutation_block`, and this tool was the outlier.
The surviving gates did not cover the gap: the task's required permission is
`gitea.issue.comment`, which every configured role holds, and
`_ensure_matching_profile` returns a profile name both call sites discard, so
it refuses nothing. A reviewer-bound session reached the exact-owner claimant
comparison inside `assess_bootstrap_lock_recovery` and was refused there —
one layer too late, with no namespace evaluation and no BLOCKED audit record
of the attempt.
Adding the call alone would have been inert. `check_author_mutation_namespace`
routes through `role_session_router.required_role_for_task`, which reads
`TASK_REQUIRED_ROLE` — not `task_capability_map` — and that table had no entry
for this task, so the check short-circuited to "allowed" for every caller.
The task is therefore registered in `TASK_REQUIRED_ROLE` and `AUTHOR_TASKS`,
matching the role the capability map already records.
The reviewer-namespace check alone is also insufficient for a task gated on
`gitea.issue.comment`, since merger, controller, and reconciler profiles hold
it too. `role_namespace_gate.check_author_role_kind` is added as an opt-in,
additive wall requiring the active profile's derived role kind to be exactly
`author`; `mixed` is refused rather than admitted. `_namespace_mutation_block`
gains a keyword-only `author_role_exclusive` flag, default off, so the six
pre-existing call sites are byte-for-byte unchanged.
Refusals produce the standard structured denial (`namespace_block: true`,
`mcp_namespace`) and the standard BLOCKED audit record, and no lock, lease,
generation, branch, worktree, issue, or PR is touched. Valid `prgs-author`
execution is unaffected. No reviewer permission is broadened and no existing
role wall is weakened.

gitea_bootstrap_author_issue_worktree wrote a lock no downstream author
operation accepts, then directed the author straight to implementation. Once
the branch carried commits, heartbeat, re-lock, exact-owner renewal, and the
#447 create-PR guard all refused simultaneously and no sanctioned recovery
path remained eligible.
Each of those gates is individually correct. The defect was that two writers
disagreed about what a lock is.
- Add author_lock_contract as the single canonical definition: claimant,
work_lease, lock_provenance, generation, and an explicit expiration state.
Both gitea_lock_issue and bootstrap now build through it.
- Promote issue_lock_store.lock_claimant to the one shared claimant reader and
use it in the ownership check, so a claimant recorded at the lock top level
is read rather than refused. The values are still compared against
server-resolved identity and profile, so no legacy placement grants anything
the canonical placement would not.
- Represent missing expiration explicitly. An absent expires_at previously read
as "not yet expired", leaving a malformed lock permanently non-expiring and
permanently ineligible for #760 renewal.
- Bootstrap reads its lock back and verifies it structurally before reporting
success. A partial lock fails closed while the worktree is still
base-equivalent, names the missing fields, and never reports
implementation_allowed. Its exact_next_action now matches the state returned.
- Add gitea_recover_incomplete_bootstrap_lock for locks already written by the
old bootstrap, including those whose branches carry pushed commits. It never
moves, resets, or rewinds a branch, never requires base-equivalence, never
pushes or opens a PR, and touches only the target lock. It proves repository,
issue, claimant username and profile, branch, worktree, registration, and
head before writing, refuses healthy foreign-owned locks, and mints
provenance and authorization server-side.
- Add gitea_inspect_issue_lock_contract, a strictly read-only surface.
- Document the required ordering and the recovery path.
The #447 provenance guard is unchanged and the sanctioned source set was not
widened: bootstrap now satisfies the guard rather than the guard being relaxed
to admit bootstrap.
Tests: 61 new cases covering the canonical schema, immediate heartbeat,
renewal before and after commits, the create_pr guard, executable next actions,
partial and malformed and missing-expiration and expired and same-owner and
foreign-owner and legacy locks, recovery isolation, read-only inspection, and
the full bootstrap-implement-commit-push-create_pr regression against isolated
fixtures.

Issue #949 was preserved and not recovered: its branch remains at

Addresses review 623 on PR #946 (B1 blocker, F2 medium, F3 minor).
B1 - the wiring this branch exists to install had no regression coverage.
The existing suite exercised owning_pr_renewal_from_lock,
_owning_pr_continuation_from_lock and the duplicate gate directly, but never
drove an enforcement path, so reverting any of the three call sites left the
whole repository green. Add tests/test_issue_945_enforcement_path_wiring.py,
which drives the real mcp_server._enforce_locked_issue_duplicate_recheck (the
shared recheck behind gitea_commit_files and gitea_create_pr),
mcp_server.gitea_assess_work_issue_duplicate and
mcp_server._prove_author_ownership_for_pr against a renewal-bearing lock, and
asserts each grants the exemption. Reverting the commit/create-PR recheck to
the recovery-only rebuild now fails 8 tests and 4 subtests; reverting the
assessor or the push prover fails 2 each. The suite also keeps the fail-closed
matrix on the real paths: an open PR alone, a second PR, a different PR,
branch, issue or head, identity and profile mismatch, ungranted and malformed
renewal blocks, and sequential-task non-inheritance are all still refused.
F2 - the claimant check compares lease_renewal.identity/profile against the
claimant recorded on the same lock file. Both sides are server-written fields
of one document, so it is an internal-consistency check, not verification of
the live authenticated caller. Correct the docstring and the inline comment to
say so, and document the binding that actually prevents cross-session reuse:
the enforcement paths load the lock through _load_existing_issue_lock() with no
issue coordinates, which resolves issue_lock_store.read_session_issue_lock() to
the session pointer at session-{os.getpid()}.json, so lock selection is scoped
to the operating-system process. Its limits are stated too - per-process rather
than per-authenticated-user, silent on locks reached by explicit coordinates,
and silent on two roles sharing one process. Live identity and profile stay
enforced by the mutation-authority and profile gates, not by this rebuild.
F3 - _owning_pr_continuation_from_lock previously fell through to renewal when
a dead_session_recovery block was present but failed to rebuild, so a recovery
record naming one PR could be bypassed by renewal evidence naming another.
Present-but-unusable recovery evidence is now ambiguous rather than absent and
fails closed. Because an expired lease whose recorded owner has also died
satisfies both dispositions in one gitea_lock_issue call, a sanctioned pair is
a reachable state; when both rebuild, they must agree on issue, PR, branch and
every head, or no continuation authority is returned. Recovery-only and
renewal-only locks keep their existing behaviour exactly.
Validation of the resulting token against live PR state remains untouched and
solely owned by issue_work_duplicate_gate._assess_owning_pr_exemption. No
public signature, MCP tool schema, refusal shape or reason code changes.

An exact-owner lease renewal (#760) is granted the owning-PR duplicate-work
waiver inside gitea_lock_issue, but every later enforcement path rebuilt that
proof from the durable lock through
issue_lock_recovery.recovered_owning_pr_from_lock, which reads only the
dead_session_recovery block. A plain renewal persists its proof under
lease_renewal instead, so the waiver expired with the lock call and the next
author mutation was refused duplicate_commit_prevented with
owning_pr_recovery_exempted: false on the very PR the renewal had just proved.
Add issue_lock_renewal.owning_pr_renewal_from_lock as the renewal mirror of the
recovery rebuild, and resolve both halves through one helper,
_owning_pr_continuation_from_lock, in the same precedence gitea_lock_issue
applies. The three enforcement paths that previously saw only recovery evidence
now share that resolver: the commit/create-PR duplicate recheck, the read-only
duplicate assessor, and the push-ownership prover.
The rebuild re-applies the equality the renewal assessor required (PR head ==
local head == remote head) and additionally binds the record to the claimant the
lock names, so a renewal block cannot be reused under another identity, profile,
or workflow session. Validation of the resulting token against live PR state is
unchanged and still owned solely by
issue_work_duplicate_gate._assess_owning_pr_exemption, so repository, issue, PR,
branch and head binding continue to be enforced in exactly one place.
No public signature, MCP tool schema, refusal shape, or reason code changes.
Dead-session recovery behaviour is untouched.

gitea_bootstrap_author_issue_worktree referenced four globals that commit
a942afe (#850) introduced without ever defining:
_active_username 1 reference, 0 definitions
_active_profile_name 1 reference, 0 definitions
_current_session_id 1 reference, 0 definitions
_author_mutation_block 1 reference, 0 definitions
Evaluating the call arguments therefore raised
NameError: name '_active_username' is not defined
before author_issue_bootstrap.bootstrap_author_issue_worktree was entered, so
the capability was unusable for every caller including dry_run=true. The fourth
name, _author_mutation_block, sits on the reviewer-stop refusal path and was
found by the generalised regression test rather than by the original report.
The defect was unreachable until PR #942 (#941) wired the bootstrap scope into
workflow_scope_guard: before that, verify_preflight_purity refused first with
missing_issue_worktree, masking it.
Changes:
* _active_username reads the immutable #714 session context that gitea_whoami
seeds — the identity pin every other mutation gate already consults. An
unbound context returns None so callers fail closed rather than acting as an
unverified actor; a profile's expected_username is never substituted.
* _active_profile_name prefers the live get_profile() and falls back to the
bound session context only when the profile cannot be read.
* _current_session_id mints the same "<profile>-<pid>-<hex>" shape as the three
pre-existing lease call sites, bound once per process so repeated calls
describe one session instead of a fresh owner per call, which would make
lease-ownership comparisons unsatisfiable. None is never memoised.
* _author_mutation_block returns the uniform refusal shape the other author
mutations already return for the same check_author_mutation_after_reviewer_stop
block.
No guard, signature, or permission changes. Wrong-role, wrong-profile,
wrong-identity, stale-runtime, expected-base and workflow-scope enforcement all
still gate the call; the helpers only supply values the service then validates
fail-closed (missing_active_identity / missing_active_profile /
missing_owner_session / stale_concurrency_pin).
Regression: tests/test_issue_943_runtime_context_helpers.py (27 tests). The
generalised test resolves every global the wrapper's body references against
module globals and builtins, so the next missing reference fails too rather
than only the three named here — that test is what found
_author_mutation_block. Coverage also coversdry-run reaching and completing the

PR #926 (#892) taught create_issue_bootstrap.bootstrap_permits_control_checkout
to accept task_scope=author_issue_bootstrap and wired that canonical decision
into the #274 branches-only enforcer and the #604 anti-stomp preflight. A third
enforcement path was left unwired.
workflow_scope_guard kept its own copy of the clean-root author decision, gated
on create_issue_bootstrap.is_create_issue_task -- a task-name allowlist that
never contained bootstrap_author_issue_worktree. The real call path
gitea_bootstrap_author_issue_worktree
-> verify_preflight_purity
-> _enforce_issue_scope_guard
-> workflow_scope_guard.assess_production_mutation_guards
therefore raised ProductionGuardError(missing_issue_worktree) before
assess_author_issue_bootstrap was ever consulted, leaving the #892 deadlock
partially present and blocking issue #931.
Changes:
* workflow_scope_guard.assess_root_source_mutation accepts the server-derived
bootstrap_assessment and, for the clean-root author case, consults the
canonical bootstrap_permits_control_checkout decision instead of a local
task-name allowlist. The create_issue arm is unchanged.
* workflow_scope_guard.assess_production_mutation_guards forwards the evidence.
* _enforce_issue_scope_guard accepts and threads the same assessment the #274
and #604 guards already consume, so all three judge identical evidence, and
waives the pre-ownership issue-lock requirement for the bootstrap task via
that same canonical decision rather than a second task-name allowlist.
* verify_preflight_purity passes the once-computed assessment at both sites.
The waiver cannot widen: the predicate fails closed on missing, malformed,
cross-scope, dirty, drifted, or wrongly bound evidence, so ordinary author
source and test mutation from the control checkout stays forbidden and the
#274/#604/#618/#683 protections are unchanged.
Regression: tests/test_issue_941_scope_guard_bootstrap_wiring.py drives the
real enforcer rather than the authorization helper in isolation, which is why
#892's own predicate tests passed while the live bootstrap stayed blocked.

Addresses the two blockers raised in the PR #886 review (comment 16559) for
issue #663.
B1 — apply_authorized ignored restart-class authorization.
The #663 restart-class matrix and the #661 drain-proof hard gate are
independent authorizations that first coexisted when PR #882 landed on
master and this branch merged it. The union preserved both, but the apply
decision consulted only the drain gate:
payload["apply_authorized"] = gate.allow
so a clean drain proof — or an authorized break-glass, which needs no proof
at all — reported apply_authorized: True for a class the least-privilege
matrix had just denied, in the same payload carrying allow_restart: False
and "role 'author' may not request full_mcp_restart". One environment
variable therefore collapsed the whole nine-class matrix for the apply
decision, including host_restart.
The apply decision is now the conjunction of both authorizations, and
apply_gate carries drain_gate_allow and restart_class_authorized so a denial
is attributable to the authorization that produced it. Break-glass keeps its
purpose — bypassing the drain proof — and never bypasses the class matrix.
No existing fail-closed behaviour is weakened: allow_restart, drain-proof
verification, fingerprint binding, and requester authorization are untouched.
B2 — docs/mcp-restart-coordinator.md described pre-#661 behaviour.
The document still called the drain proof "a separate child" and omitted
drain_proof_json and request_break_glass from the published signature, so a
safety document asserted there was no gate where a gate now exists. It now
documents both parameters, states that the gate executes inside this tool,
and records dry-run versus apply behaviour, authorization ordering, the
break-glass scope, and fail-closed conditions as implemented.
Regression coverage.
tests/test_issue_886_apply_authorization_conjunction.py exercises the MCP
tool itself, which previously had no test at all — that absence is why the
defect shipped. It pins both conjunction directions, proves a clean proof
cannot override a role, approval, unknown-class, or missing-target denial,
proves break-glass does not collapse the matrix for any worker role or
restricted class, and proves the existing scoped and unscoped paths and the
#661 denials still hold. Against the pre-fix tree 24 of these fail; against
this commit all 19 pass with 45 subtests.
tests/test_mcp_restart_governance_docs.py now binds the published signature
to inspect.signature() of the real tool and forbids the stale pre-#661
phrasing, so the drift that produced B2 cannot return unnoticed.
Verification: targeted restart/drain/governance/webui suites 194 passed,
113 subtests. Full suite 23 failed, 5230 passed, 6 skipped, 912 subtests —
the failure set is identical to the reviewed baseline at 9bc021e
(23 failed, 5201 passed), with +29 passing from the added tests and no new
or changed failure. Zero conflict markers; py_compile passes; the #882
union remains intact in both directions.

Stale-runtime and runtime-mode mutation refusals previously shared the
permission-denial channel, so permission_report claimed a missing op the
active profile already held and recommended gitea_activate_profile.
Typed blocker_kind payloads report reconnect-only recovery for staleness,
omit permission_report for non-permission gates, and fail closed when a
permission_report would invent a missing permission the profile holds.
Brings PR #886 up to date with master @ 2f4dec8323
(8 commits behind), resolving the single conflicted file.
Conflict: gitea_mcp_server.py, both hunks inside gitea_request_mcp_restart.
Both sides were purely additive to the same tool, so both are kept in full:
- Branch side (#663, restart classes): parameters restart_class,
target_session_id, target_role, target_connector; payload keys
controller_approval_authorized, requester_role, requester_permissions.
- Master side (#661 via PR #882, drain-proof hard gate): parameters
drain_proof_json, request_break_glass; the explanatory comment describing
the apply-path hard gate and break-glass authorization.
No behaviour from either side was dropped, reordered, or reimplemented. Every
parameter from both sides is already consumed by the auto-merged function body
(restart_class and the three target_* arguments flow into the coordinator call;
drain_proof_json and request_break_glass drive the dry_run=False hard gate), so
the union is the only resolution that keeps the merged function coherent.

Add `drain_proof.py`: a machine-verifiable DrainProof artifact plus a
fail-closed verifier and the hard gate the sanctioned restart-apply path
must consult, so a restart can never proceed on a stale or false "ready"
claim (#655 umbrella, child of #658 coordinator / #659 drain / #660
checkpoints).
- DrainProof: HMAC-SHA256 keyed proof-id over a canonical body using a
per-process secret -> non-forgeable within the process; a proof minted in
a prior daemon process will not verify after restart. Short TTL (120s).
- build_drain_proof(): mints the proof from the #658 impact report + the
drain-mode outcomes. Checklist: no in-flight mutations, assignments
stopped, checkpoints complete, handoffs ok, leases handled, acks-or-
timeout. Every check fails closed on missing/ambiguous evidence; the
no-in-flight-mutations and leases-handled checks are derived from the
authoritative impact report, not self-reported.
- verify_drain_proof(): fail-closed — rejects missing, malformed, expired,
signature-mismatched (forged/tampered/prior-process), unclean, or
stale-fingerprint proofs; recomputes cleanliness from the checks rather
than trusting the flag.
- gate_apply_restart(): allow only on a valid clean proof; deny -> durable
incident descriptor; break-glass is the only bypass and is never silent.
- Checkpoint completeness is a supplied input, not a hard dependency on the
(still-unmerged #660) checkpoint schema.
Wire the gate into gitea_request_mcp_restart: dry_run=False now enforces the
hard gate (drain_proof_json required; break-glass via request_break_glass +
GITEA_BREAKGLASS_RESTART_AUTHORIZATION env). The tool still performs no
actual restart — execution remains a further child.
Tests: tests/test_drain_proof.py — 25 cases covering AC#1-4 (apply without
proof denied, successful drain verifiable, open unsafe mutation fails,
pass/fail/expired), forgery/tamper/wrong-secret/stale-fingerprint rejection,
break-glass bypass, and secret hygiene. 25/25 pass (coordinator suite
unaffected: 40/40 together).

`gitea_update_pr_branch_by_merge` advanced a PR's remote head but never
advanced the linked durable issue lock's recorded head. After the owning
session died the drifted lock became unrecoverable and no further
synchronization was possible (PR #866 / issue #855).
Write-side (prevents future drift):
- issue_lock_store.assess/apply_durable_lock_head_refresh: on a successful
sync, CAS-refresh the durable lock's recorded head from the exact expected
PR head to the resulting head, re-verifying repo/issue/branch/worktree/
identity/profile/live-session ownership, with read-after-write verification.
- gitea_update_pr_branch_by_merge now refreshes the lock after the remote
advance and reports a PARTIAL LIFECYCLE FAILURE (success=False) when the
refresh fails, instead of falsely reporting a full synchronization.
Read-side (recovers already-drifted locks):
- issue_lock_worktree.read_merge_sync_provenance: server-side git observation
proving a remote head is a sanctioned base-into-branch merge that preserved
the branch mainline back to the recorded head.
- issue_lock_recovery: new HEAD_RELATION_REMOTE_MERGE_SYNCED accepts a
dead-session lock whose recorded head is a strict merge-sync ancestor of the
live PR head — and only that. Rewrites, rebases, force-pushes, non-ancestor
heads, dirty worktrees, live/competing owners, and wrong repo/issue/branch/
identity/profile all stay protected.
No existing exact-head, branch-protection, parity, workspace, identity, role,
or mutation-safety gate is weakened. All provenance is server-derived; nothing
is reachable from an MCP caller.
Tests: tests/test_issue_871_durable_lock_head_refresh.py (32 cases) covering
first/second sync, CAS, ownership, partial-failure, merge-sync recovery
happy-path and every fail-closed branch. Full suite: 4789 passed, 13 pre-
existing baseline failures unchanged.

Child of umbrella #655 (governed MCP restart coordination); builds on the
#657 restart-path inventory. Adds a central coordinator that evaluates live
control-plane state before a restart and returns a blast-radius impact
preview, so operators and the web console (#642/#652) can see what a restart
would disrupt before concurrent LLM work is destroyed.
Changes
- restart_coordinator.py (new) — pure classification: inventory -> impact
report DTO (RestartImpactReport/SessionImpact/LeaseImpact). Verdicts:
safe / unsafe / override. Never restarts anything; fails closed on an
incomplete inventory.
- control_plane_db.py — additive ControlPlaneDB.list_sessions() read-only
session inventory (the process-level unit a restart kills).
- gitea_mcp_server.py — new dry-run MCP tool gitea_request_mcp_restart:
gathers sessions/leases/terminal-lock from the #613 DB, calls the
coordinator, returns the report. Override authority is read from the
environment, never self-asserted (#630/#710 F1 pattern). Apply is gated
by a later drain proof (non-goal here).
- docs/mcp-restart-coordinator.md + docs/mcp-restart-impact-sample.json — doc
and a real dry-run sample report.
- docs/mcp-tool-inventory.md — register the new tool (inventory sync).
- tests/test_restart_coordinator.py (new) — 15 tests: multi-session fixtures,
deny-when-critical-section-open, fail-closed deny, override, terminal lock,
stale heartbeat, JSON-serializable DTO, list_sessions.
Tests: pytest tests/test_restart_coordinator.py -> 15 passed. Full suite:
13 failed / 4753 passed; all 13 reproduce identically on clean master
@ef14622 (0 regressions). The residual test_issue_781 doc-registry failure
is a pre-existing baseline gap for gitea_rebind_dirty_same_claimant_author_session
(merged #864, undocumented on master) — out of scope for #658.

Adds a single-target path for post-merge cleanup so a reconciler can
complete one merged PR without a batch sweep across unrelated PRs.
## PR-scoped selector
gitea_reconcile_merged_cleanups gains an optional pr_number. When set,
only that merged PR is assessed and acted on: the PR is resolved live and
fails closed on an invalid/non-positive number, an unresolvable or
ambiguous PR, or an unmerged PR; reviewer scratch worktrees are filtered
to that PR; and the report's entry set is pinned to exactly [pr_number],
failing closed on any drift. The existing execute loop then operates on
the single pinned entry only -- worktree removal, ownership reassessment,
then remote-branch delete -- with no unrelated target. Batch behaviour is
unchanged when pr_number is omitted.
## Expired reviewer-lease reclaim (AC4)
An expired or stale reviewer lease no longer protects an already-merged
branch forever. branch_cleanup_guard.assess_expired_reviewer_lease_reclaim
makes the decision explicitly and fail-closed: reclaim only when the lease
is a reviewer lease, its status is expired/stale, the PR is proven merged,
the owner process is proven dead, and no competing active claimant uses
the branch. _collect_branch_ownership_records supplies that evidence from
authoritative state (live PR merged-state, lease owner liveness, and the
full ownership inventory for competing-claimant detection) and evaluates
it only after the complete inventory is built, so the post-worktree-removal
reassessment is what unblocks the branch delete. Any unknown fails closed.
Author/merger/controller/reconciler leases are untouched; active leases,
worktree bindings, issue locks, and live sessions still block.
## Tests
- tests/test_issue_855_expired_reviewer_reclaim.py: full fail-closed matrix
for the reclaim decision plus collector wiring (merged+dead+uncontested
reclaims; unmerged, live-owner, competing-worktree, and author-lease
cases stay protective).
- tests/test_branch_cleanup_guard.py: exact-PR selector coverage (ignores
newer PRs in the batch queue, execute mutates only the selected PR,
unknown/not-merged/invalid fail closed, batch mode preserved).
Changed-surface suites pass; the 2 pre-existing test_branch_cleanup_guard
failures and test_reconciler_supersession_close reproduce identically on
master 6d0015ca and are unrelated to this change.

Introduce an explicit, fail-closed recovery operation that rebinds a live
author session to an already-registered dirty issue worktree when the durable
lock still belongs to the same identity/profile and the recorded owner PID is
provably dead. Ordinary locking remains clean-worktree-only; this path updates
only stale lock/session provenance, preserves every dirty byte under fingerprint
pins, and grants create-PR-sanctioned provenance without remote sync or recovery
worktrees.
Also stop treating dead-owner session pointers as live mutation workspace
bindings so a stale dead-owner pointer cannot poison unrelated author work.
- Fix F1: Prepare recovery worktree detached at remote_head without git checkout -B to avoid exit 128 when branch is held by source worktree
- Fix F2: Pass recovery_sanctioned=True in bind_session_lock and assess_same_issue_lease_conflict
- Fix F3: Add SOURCE_RECOVER_DIRTY_ORPHANED to SANCTIONED_LOCK_SOURCES
- Fix F4: Stop after Phase 4 dirty apply when conflicts exist; do not finalize session binding
- Fix F5: Dynamically query competing live locks and workflow leases in MCP server
- Fix F6: Fail closed on recovery worktree resume when HEAD does not match expected remote_head
- Fix F7: Fail closed on remote HEAD observation failure rather than copying expected_remote_head pin
- Fix F8: Enforce foreign overwrite protection requiring same claimant or sanctioned reclaim
- Fix F9: Add real multi-worktree integration tests for prepare_recovery_worktree and lock rebind
- Fix TestWorktreeStart: Bypass session lock check for dry-run and review/pr-* branches in scripts/worktree-start
Add an explicit recovery operation for same-claimant dirty registered
worktrees under malformed PID-less durable locks, with crash-safe journals,
dirty byte preservation, path-level conflict detection, and live session
binding. PID-less locks are never treated as live merely because expiry is
absent.

gitea_audit_worktree_cleanup had no PR linkage. Issue worktrees therefore
reported pr_number=null and classified as active_issue_work with
removable=false permanently, even once their PR was merged and the head was
already contained in master. Observed on live master 9301739910: 42
issue_work worktrees, 0 removable, 0 with pr_number populated, while
gitea_reconcile_merged_cleanups reported the same worktree safe to remove.
Two independent gaps caused it:
* build_worktree_metadata was never given a pr_number, and only open PRs were
fetched, so no owning-PR evidence existed at all.
* clean_stale_removable was unreachable for issue_work: it required
ttl_expired, derived from a last_used_at that nothing populates, and
is_ttl_expired fail-safes to False when the timestamp is unknown.
This adds deterministic merged-PR linkage and gates removal on the complete
cleanup policy:
* build_pr_index / resolve_owning_pr link a worktree branch to exactly one
owning PR. Competing PRs on one branch, a still-open owner, a head-branch
mismatch, or missing PR state all fail closed while still reporting the
resolved pr_number.
* assess_merged_pr_worktree_cleanup requires all of: conclusive merged
ownership, branch agreement, containment of the head in authoritative
master, no open/competing PR, no active lease, no issue lock, no live
session, a clean tree, and a non-protected checkout. Unknown state blocks.
* Containment reuses merged_cleanup_reconcile.is_head_ancestor_of_ref so the
audit and the PR-scoped reconciler agree on what "already landed" means.
Lease evidence is now supplied. audit_branches_directory already accepted
leased_branches but the MCP tool never passed it, so has_active_lease was
false for every worktree in a live run. That was inert only while issue
worktrees could never become removable; it is wired to authoritative
control-plane leases here, scoped so a lease on issue N protects that issue's
work worktree and not a baseline or review tree merely named after it.
Issue work no longer becomes removable on TTL age alone, since age is not
proof that a branch landed and would otherwise reclaim a worktree holding
unmerged commits. conflict_fix keeps its existing TTL behaviour, and review,
baseline, merge-simulation, detached, dirty, open-PR, and protected
classifications are unchanged.
The assessor still performs no deletion and gains no cleanup mutation. This
is assessor-side only and does not implement the PR-scoped executor or the
expired-lease reclaim policy tracked separately by #855.
