`cargo test --workspace` could not run at all: dependency resolution failed with "aws-types@1.3.16 requires rustc 1.91.1" on the 1.91.0 default toolchain, so the gate the project documents was dead. Making it run exposed a compile break and two wrong tests that had been invisible for months. Now green end to end: 143 suites, 3155 tests, exit 0. Toolchain - rust-toolchain.toml pins the DEV toolchain to 1.91.1. The published MSRV stays `rust-version = "1.91"` (the engine builds on 1.91.0); only tidalctl's AWS SDK chain needs the patch release, and it now declares that itself. Consumer crates migrated to the current engine API (clean cutover) - iknowyou-engine: `AgentPolicy` gained five m10 read/profile-override fields; the literal now spreads `..AgentPolicy::default()` as the engine's own doc example does, so future fields do not break it again. - forage-engine: `RetrieveResult` gained p1 `reasons`. The app builds its own candidate pool, so it now tags what it knows: PreferenceMatch for the preference-vector blend, SemanticMatch (with the seed item) for similar-to-saved, ExplorationBudget for pinned discoveries. - forage-engine: `url_to_item_id` folded into the u32 item universe. The engine narrows item IDs to a u32 slot in durable per-user state and rejects anything above u32::MAX rather than alias two items forever, so every add_item with a 64-bit FNV hash failed. 9 of 28 smoke tests were failing on this alone. - forage-engine: bridge items read the top-2 preference CLUSTERS via `query_vectors`, not the single centroid from `preference_vectors().get()`. Since m12 that accessor returns only the strongest cluster, so a tech+jazz user whose interests split into two clusters looked single-interest and never bridged. Falls back to top-2 dimensions when a user has one cluster. Reconcile tests corrected to the shipped contract - tidal/tests/m8p3_reconcile_production.rs asserted `3 + 5 == 8` for a windowed count after heal. `take_crdt_snapshot` deliberately keys signal contributions to ONE canonical contributor (ShardId::SINGLE) because signals are relayed from a single writer, so per-node attribution double-counted every replicated event on every reconcile. Merge is therefore LWW on (last_update_ns, score) plus PN-counter per-node max: nodes converge on the more complete accumulator. The old expectation was asserting the bug that fix removed. - Rewrote to assert convergence, count survival (not 0), and no inflation, and added `repeated_reconcile_of_converged_nodes_does_not_creep` - the regression guard for the creep itself, which nothing covered. Pre-commit hook unified - hooks/pre-commit dropped `-D warnings`: each crate's `[lints]` table is the source of truth (`clippy::all`/`unwrap_used` deny, `pedantic` warn), and the flag promoted ~58 deliberate pedantic warnings in integration tests to errors, making every Rust commit impossible. - It now lints all five tidal crates instead of path-matching `tidal/`, which silently skipped tidal-server, tidal-net, tidal-stress, tidalctl and applications/ - the rot above lived in exactly those crates. Ported the CODING_GUIDELINES file-length, println, and unsafe-SAFETY checks from the divergent untracked copy that this replaces. - CONTRIBUTING.md now documents the real commands and the toolchain/MSRV split. Fleet recovery and soak - scripts/restore-fleet.sh: the fail-closed selective restore, promoted out of an ignored tmp/ directory into the repository. Preflights retained storage, digest-pinned images, parked state, and aggregate plus per-PV-node scheduler headroom before the first scale; writes a durable transcript under tmp/restore-logs/ with structured start/error/rollback/complete events. - k8s manifests park the standalone store, the RF3 cluster, and the soak monitor at zero replicas with restore-fleet.sh as the only supported scale-up path. - soak-eval/soak-watch and the nightly CronJob fail closed on stale or missing restart evidence instead of silently skipping the restart-aware half of the gate. - docs/ops/capacity-planning.md corrects the RAM envelope to the real hot-tier formula and separates analytic totals from the measured process envelope.

# The tidalDB CLUSTER: ONE StatefulSet, every pod a region (m11p5 §4).
|
||
#
|
||
# MUTUALLY EXCLUSIVE with the standalone set in k8s/. Both source workloads are
|
||
# parked at 0. `scripts/restore-fleet.sh` restores one selected data plane:
|
||
# cardinality 1 in namespace `tidaldb`, or three `cluster --region` processes in
|
||
# namespace `tidaldb-cluster` with real quorum-ack writes. Never run both.
|
||
#
|
||
# WHY ONE StatefulSet (not one-per-region): the m11p5 bind/advertise split lets
|
||
# every pod mount the SAME topology ConfigMap (peers are advertised by per-pod
|
||
# DNS; the local socket binds 0.0.0.0), so a single StatefulSet with stable pod
|
||
# identities tidaldb-{0,1,2} IS the three regions. Scaling is `kubectl scale`
|
||
# (see docs/runbooks/kubernetes.md): pod N>=3 auto-seed-joins as a learner and
|
||
# auto-promotes to a voter — no file edits, no per-pod manifests.
