- `KvEngine::Postgres` slotted in: all six kv-op dispatch arms, the `KvCursor::Postgres` materializing body behind `AnyCursor`'s kv arm (the recorded sub-enum design point, landed as predicted), and the engine-neutral `ensure_gc_schema` call creating `gc_pins` + `gc_window` in the fresh schema at construction (the fleet host's both-tables row, ADR-012 §5) - The two named constructors behind feature `postgres` (default-off): `dual_tier_postgres_local(config, opts, root, threshold, window_delay)` — the fleet-capable-kv production shape — and `kv_only_postgres(config, opts, threshold, window_delay)`; the DSN connection settings + engine opts ride the constructor parameters, never invented defaults. `PgOpts` is pub and re-exported from `lib.rs` (it is on the public constructor signature now) - The sweep's durable form runs on the postgres host: the form body extracted into `sweep_window_durable<W: EngineWindowState>` (sqlite's arm delegates, behavior unchanged), both SQL-backed arms keyed off the kv-engine enum, never a flag — wave 5's pg-lo dormancy slots in without reshaping - Non-fleet posture recorded on both constructors (ADR-012 §3): implicitly `fleet: false`, the ADR-005 in-process protocol verbatim, the `fleet: true` declaration is wave 6 and slots in without reshaping - Stale scope notes updated to the landed state (engine-representation doc, `KvCursor` design point, fleet-declaration paragraph, one-window-host paragraph, postgres module doc, gc.rs companion-seam note); the batch-delete helper's scope note stays (wave 6 consumer) - 5 new env-driven construction tests (skipping server-less): the modes construct and introspect, both GC tables exist in the fresh schema, the window-delay default is the pinned 5-min constant and tunable (`0` legal), the kv-only rejection wiring is unchanged, the dual-tier shape round-trips through both tiers, and the durable form is observed staging/executing across sweeps on the postgres host Verification: `cargo test` 69/19/3 ok; `cargo test --features postgres` 102/19/3 ok live (pglo-poc harness) and green server-less; `cargo test --no-default-features --features postgres` (the pg-pure build, ADR-013 §4) 75/2/3 ok server-less; `cargo test --all-features` 157/54/4 ok; clippy `-D warnings` green (default, postgres, pg-pure, all-features); `cargo fmt --check` green; `cargo doc --no-deps` clean.
