- KvEngine::Sqlite slots in; all six kv ops dispatch; the kv cursor body dispatches through a new KvCursor sub-enum behind AnyCursor's one kv arm (the kv-arm-over-multiple-kv-engines design point, recorded) - dual_tier_sqlite_local (kv = sqlite + large = local, the default-build production shape) and kv_only_sqlite constructors — both feature-gated on sqlite (default-on), both taking the threshold and the delete-window delay, fallible where I/O is fallible (Err(Error::Io) per the dual_tier_mem_local pattern) - ensure_gc_schema runs at construction via the engine-neutral KvEngine call (sqlite's body creates gc_window only); the window-delay shipped default is the pinned DEFAULT_DELETE_WINDOW_DELAY (5 min, ADR-008 §2), constructor- tunable, Duration::ZERO legal — the store carries the value for the sweep's durable form to consume - the one-window-host posture recorded in the module doc (the durable window hosts on the kv engine when it is SQL-backed; wave 5's pg-lo dormancy slots in without reshaping) - stale empty-set scaffolding updated to the landed state: the #[allow(unused_variables)] attrs off the KvEngine methods; the scope notes in store.rs, backend.rs, sqlite.rs, gc.rs - constructor unit tests: mode/threshold/window-delay introspection, the GC schema observed in the fresh database (window table present, gc_pins never), kv-only rejection wiring unchanged, and the dual-tier shape round-tripping end-to-end through both tiers Verification: cargo test 62 passed (default; 5 new tests), cargo test --all-features 117, cargo test --features mem 117, --no-default- features --features mem 97; cargo clippy --all-targets -- -D warnings clean (default + all-features); cargo fmt --check clean; cargo doc --no-deps at the pre-existing warning baseline.
