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.
Add support for defining ranking profiles in schema YAML, allowing
deployments to override builtin profiles with deployment-specific
signal names and tuning parameters.
- Add override_register() to ProfileRegistry for clean builtin replacement
- Add with_profiles() to TidalDbBuilder to thread schema profiles
- Parse profiles section in config.rs with full sort/strategy/agg support
- Validate that profile signal references exist in schema at startup
- Change load_schema() to return (Schema, Vec<RankingProfile>)
This closes the gap where the builtin for_you profile referenced
signals (view, like, share) that don't exist in deployment schemas,
causing all feed scores to normalize to 1.0.

Clap now reads PORT from the environment, accepting either a bare port
number (e.g. 8080 -> 0.0.0.0:8080) or a full host:port. CLI --listen
flag still takes precedence. Deploy Dockerfile defaults PORT=9500 and
removes the hardcoded --listen argument.

Matches the response shape used by all other services in the
infrastructure (ok, service, cause on failure).

Add /health/startup and /health/live probes, flip readiness to 503 on
SIGTERM so k8s stops routing before drain. Update standalone Dockerfile
for internal deployment: port 9500, schema mounted at runtime (not baked
in), persistent data dir, non-root user with fixed UID 10001.

- 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

Fix 9 compilation errors across tidal-server and testing/cluster.rs so
that `cargo run -p tidal-server -- standalone` works end-to-end.
Bugs fixed:
- cluster.rs: wrong return types `RetrieveResult`→`Results` and
`SearchResult`→`SearchResults` on retrieve/search helpers
- state.rs: `RegionId` imported from private path; now uses
`tidaldb::replication::RegionId`
- state.rs: missing `Ok()` wrapper on `ServerState::cluster()` return
- state.rs: cluster match arms returned `TidalError` where `ServerError`
required; added `.map_err(ServerError::from)` on write_item,
write_embedding, retrieve, search
- error.rs: `Result<T>` alias lacked default E param; callers in router
used two-arg form `Result<T, AppError>` — changed to
`Result<T, E = ServerError>`
- router.rs: `with_state()` called before cluster routes were added,
making `app` `Router<()>`; restructured to call `with_state` once at end
- router.rs: `TidalErrorWrapper(TidalError)` used to map `QueryError`;
fixed with `|e| TidalErrorWrapper(e.into())`
- router.rs: `Search::limit()` takes `u32` but code cast to `usize`
- router.rs: `bm25_score`/`semantic_score` are `f32` in SearchResultItem
but `f64` in response struct; added `.map(f64::from)` conversion
Also split cluster.rs into cluster.rs + cluster_transport.rs to stay
under the 600-line limit required by CODING_GUIDELINES §9.
Verified all README curl examples work:
POST /items, POST /embeddings, POST /signals, GET /feed, GET /search,
GET /health all return correct HTTP status codes and JSON responses.
