The acks_or_timeout check treated an absent `acks` key as proof that no
session needed to acknowledge: `drain_state.get("acks") or {}` collapsed
absent, None, and empty into the same value, and the resulting empty mapping
satisfied `no_sessions_to_ack`. The impact report's counts.sessions_live_other
was never consulted, so absence of evidence was read as evidence of absence.
Reproduced at head 1cbbde0089: with
sessions_live_other = 3 and the acknowledgement key absent, acks_or_timeout
passed with detail "no other live sessions required to acknowledge", the proof
minted clean, and gate_apply_restart returned verdict allow — a restart
authorized against three live sessions with zero acknowledgement evidence, and
the resulting artifact carried a valid signature.
Whether acknowledgement is required is now derived from the impact report,
never from the shape of the drain state:
- _live_session_count() reads counts.sessions_live_other and returns None for a
missing, malformed, negative, or bool value, so an unreadable report fails
closed instead of reading as "nobody was live".
- Absent, None, non-mapping, empty, partially-covering, and unparseable or
stale acknowledgement data all fail closed while live sessions require
acknowledgement.
- _is_acknowledged() no longer coerces with str(); only an explicit
"ack"/"acked"/"acknowledged" string counts, so None, timestamps, and
"pending"/"stale" markers are never read as an acknowledgement.
- Present-but-unacknowledged entries fail closed even when the report claims
zero live sessions: that contradiction is not safe to resolve in favour of
the restart.
- ack_timeout_policy_applied stays strict (`value is True`), so an absent, null,
or non-boolean value cannot open the gate on its own.
The genuine no-other-live-sessions case still passes, now justified by the
report proving sessions_live_other == 0 rather than by the absence of data.
Adds AcknowledgementFailClosedTests: 14 cases / 26 subtests covering missing,
null, empty, malformed, stale, partial-coverage, and unproven-count inputs,
the valid-acknowledgement and zero-live-session paths, timeout-policy
strictness, and that a failed check blocks proof.clean, verification, and the
restart gate.
Restart-surface suite: 132 passed, 38 subtests (branch baseline 118 passed,
12 subtests; +14 new tests, no regressions).

Starlette 1.3.x prefers httpx2 for starlette.testclient.TestClient; plain
httpx still works but emits StarletteDeprecationWarning.
- Pin httpx2==2.9.1 (keep httpx for MCP/runtime)
- Centralize Web UI TestClient import via tests/webui_testclient.py
- Point all test_webui_* modules at the helper
- Add regression tests that the deprecation warning is gone
Closes#682
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).

(cherry picked from commit e7bcc952bb3e820fda95acbecefeaebfa5f8fcff)
#844 only caught epic-shaped child-only records. Live allocation still
selected product vision (#652), phased roadmap (#653), and umbrella (#655)
as implement targets. Extend pre-rank semantic classification with body
markers and container labels for those coordination records, keep title-
only and incidental mentions eligible, and add a live-equivalent canary.
Closes#854
Adds the session_checkpoints section to the control-plane DB substrate
architecture doc: schema version and row identity, the column groups, the
public API surface, and the hard rules (redaction at write, reconcile
rather than blind restore, unknown live state is not a mismatch, drain
fails closed on an incomplete checkpoint, no transcript storage).
Satisfies acceptance criterion 1 of #660 ("Schema documented and
versioned") for the implementation added in 7e18dcc.

Base-sync of the #660 durable session checkpoint schema branch onto current
master. The only conflicting file was control_plane_db.py, where master added
the #651 usage_events table, migration, and indexes while this branch added the
Resolution keeps both sides in full. Verified against both merge parents: the
resolved file contains every line of master's control_plane_db.py with zero
removals, plus exactly the #660 additions (session_checkpoints table, its two
indexes, _session_checkpoint_row, write_session_checkpoint,
get_session_checkpoint, list_session_checkpoints, reconcile_session_checkpoint,
and checkpoint_completeness).

Add pure post_restart_reconcile.reconcile_after_restart classifier with a
machine-readable completion proof covering service health, sessions, leases,
capabilities, worktrees, interrupted mutations (never auto-resumed),
duplicates, and queue state. Soft-depends on #660 checkpoints (skipped with
reason when the schema module is absent).
Wire read-only MCP tool gitea_reconcile_after_restart, boot-once hook via
gitea_assess_master_parity, log_only/enforce modes (mutation_hold), and docs.

Add a versioned, redacted, reconcile-on-boot session checkpoint store to
control_plane_db so a restart can recover session identity, stage, lease
ownership, and next valid action instead of forcing human reconstruction
(umbrella #655; #628 autonomous-handoff goal).
- Bump SCHEMA_VERSION 4->5. New `session_checkpoints` table + two indexes,
added via `CREATE TABLE IF NOT EXISTS` so table creation is itself the
additive, idempotent v4->v5 migration (dependency_edges precedent).
- Writer `write_session_checkpoint` upserts the current recoverable state
per (remote, org, repo, session_id, work_kind, work_number); stage
transitions audit to `events`. Readers `get_session_checkpoint` /
`list_session_checkpoints`.
- Every free-text and JSON field is passed through `gitea_audit.redact`
before storage — no tokens/credential URLs can land in a checkpoint (AC4).
- `reconcile_session_checkpoint` is pure and never restores: it diagnoses a
stored checkpoint against live head/lease state and flags staleness (AC3).
- Drain gate: `require_complete=True` fails closed (writes nothing) when a
checkpoint is missing a drain-required field, so drain cannot complete on
an unrecoverable record.
- `lease_id`/`assignment_id` are soft references (no enforced FK) so a
checkpoint survives deletion of the lease it names; `work_number=0` is the
NULL-safe session-level sentinel.
Tests: 13 new cases (schema/version, multi-role fixtures, upsert+audit,
JSON round-trip, secret redaction, reconcile stale-head/dead-lease/
reassigned-lease/clean/unknown, drain fail-closed, sentinel key). Existing
schema_version assertion updated 4->5. Full tests/test_control_plane_db.py
suite: 33/33 pass.
