Five tasks against the wave-3 contract surface as reviewed (no amendments from the gate): - engine-postgres: the fleet-capable kv engine — the B5 row shape (fillfactor 90) in one engine-owned schema, the deadpool pool with per-connection prepared-statement discipline, the synchronous_commit parity knob wired per-connection, ON CONFLICT DO NOTHING CAS, the stable MVCC-snapshot list cursor, the batch-delete helper (key = ANY($1), consumer wave 6), the read-only virgin-store split - engine-postgres-fleet: the engine-state seam's full clause families (ADR-012 §5's postgres row — every family yes): gc_pins + gc_window, the joint tx ownership rule in the JointTx shape, pin_commit atomicity, pin_renew/pin_check/arbitrate, the pg advisory lock as the sweep lease's shipped provider; fleet activation stays wave 6 - store-postgres-construction: KvEngine::Postgres slots in, the KvCursor arm, the dual-tier/kv-only constructors (DSN + opts + threshold + window delay), the non-fleet posture recorded, the pg-pure build verified - suite-column-postgres: the first SKIP-posture column — the alkstore pg-factory pattern reused (fresh schema per open, CASCADE teardown, env-driven ALKBLOBS_PG_* settings), durable-schedule sweep rows, acceptance green against the harness server (pglo-poc :15432, verified live) - review-wave-4: the engine-wave gate (engine-vs-contract conformance) Verification: dependency graph validated (all ids resolve, no cycles, topological order clean); docs-only change.
