- impl EngineWindowState for SqliteBackend, the window family only per ADR-012 §5's sqlite row; no pin-clause or sweep-lock body exists — EngineFleetState is never implemented on this engine - ensure_gc_schema creates gc_window only (never gc_pins; the embedder's liveness table is never created — ADR-008 schema ownership) - window_stage is a key-keyed upsert: idempotent per (key, deadline), a re-stage at a new deadline updates the row - window_take is one atomic DELETE … RETURNING with the <= now boundary; future rows left in place; tableless take is a no-op read, tableless stage surfaces the engine error (the recorded read/write tolerance split) - visible_after encodes as signed i64 nanoseconds from the epoch (recorded design point; sub-second precision for test tunings) - six clause contract tests per the ADR-012 §5 sqlite row Verification: cargo test green (58 lib + 5 integration); cargo clippy --all-targets -- -D warnings green; cargo fmt --check green.
