- Eliminate the tidal/ self-contained doc mirror; docs now have two canonical
homes (root *.md and docs/), with planning/specs/research/reviews moved up
- Remove stale .agents/skills and .ai mirrors; canonicalize skills under .claude/
- Add pre-commit hook + scripts/check-docs.sh doc-guard + scripts/install-hooks.sh
- Implement M0-M10 seven-dimension review findings across engine, net, server,
and tidalctl (durability, replication, query, WAL, storage, CLI hardening)
Resolves the 142 findings from tidal/docs/reviews/CODE_REVIEW_m0-m10.md across
the engine, server, net, and CLI surfaces:
- WAL/session-journal durability, checkpoint format, and crash-recovery hardening
- Replication shipper/receiver, tenant isolation, and migration paths
- Cluster scatter-gather, router, standalone server + health/offload endpoints
- tidalctl refactored into command modules with JSON output and WAL-state tooling
- Cohort, governance, signal-ledger, and vector-registry correctness fixes
- Expanded UAT/integration/durability test coverage across all milestones
Three changes closing M8 gaps identified during verification:
1. ROADMAP.md: Mark m8p8 and m8p10 as PARTIAL (not COMPLETE).
Added Known Gaps table (G1: in-process transport, G2: tier-3
tests, G3: hash inconsistency).
2. SimulatedCluster transport now pluggable via ClusterConfig.transports.
Default (None) uses new ChannelTransport (crossbeam, same behavior).
When Some, accepts external transports (e.g., GrpcTransport from
tidal-net). Updated redeliver_missed to use &dyn Transport.
Zero regressions: all 1209 lib + 8 m8_uat tests pass unchanged.
3. Multi-process E2E test harness (tidal-server/tests/cluster_e2e.rs).
ClusterHarness spawns real tidal-server cluster OS processes,
allocates dynamic ports, generates topology YAML, polls health,
and cleans up via SIGTERM. Two tests: smoke (write + converge +
verify follower reads) and promote (leader change + continued writes).
Feature-gated behind cluster-e2e.
After a pod restart, in-memory indexes (universe bitmap, category,
format, creator, tags, duration, created_at) were empty because they
were only populated by write_item_with_metadata() calls. This caused
/health to report items: 0 and queries to return no results despite
data persisting on disk in fjall storage.
Add rebuild_item_indexes() which scans the items keyspace for Tag::Meta
entries on startup and repopulates all indexes from stored metadata.
Update m2_uat crash recovery test to assert indexes survive restart
without rewriting items.

- Extract redeliver_missed(tx, db, log) helper into cluster_transport.rs
- heal_region now removes partition then immediately ships any missed
batch-log entries to the healed follower's channel
- await_convergence refactored to call the same helper (no logic change)
- tidal-server: reload_text_index before search in cluster mode
- tidal-server: write_signal returns Result instead of panicking on unknown signal
- tidal-server: leader shows lag_events=0 (writes directly, no receiver thread)
- tidal-server: fix cluster mode error propagation (ServerError::from)
- docs/runbooks/cluster.md: add full cluster operations runbook
- docker/: add Dockerfile for containerised cluster deployment
- README.md: add tidal-server HTTP API getting-started section
- Split oversized source files per CODING_GUIDELINES §9

deserialize_start_record now returns the full (session_id, user_id,
started_at_ns, metadata) tuple — the metadata bytes were already written
by serialize_start_record but silently discarded on read.
restore_session_wal_events looks up the persisted start record in storage
for each open session and uses the deserialized metadata instead of
HashMap::new(), so fields like {"tool":"planner"} survive a crash.
The signal replay loop no longer discards _annotation — annotations are
now pushed into state.annotations during WAL replay, restoring preference
hints like "more jazz today" so FOR SESSION ranking works post-restart.
Two new integration tests in session_durability.rs verify both fixes
against a real persistent store with simulated crash (drop without
close_session). session/serde.rs split into serde/mod.rs + serde/start_record.rs
to satisfy the 600-line limit.
