1//! SQLite storage backend for the khive knowledge graph runtime.
2//!
3//! Provides entity, note, event, edge, FTS5 text search, and optional
4//! `sqlite-vec` vector storage over a WAL-mode connection pool.

8/// Periodic WAL checkpoint task.

10/// Read-only-by-intent database-integrity and WAL/checkpoint diagnostics.
11pub mod diagnostics;
12/// Error types for the SQLite layer.
13pub mod error;
14/// SQLite extension registration (sqlite-vec auto-extension).
15pub mod extension;
16/// Schema migration system (versioned migrations).
17pub mod migrations;
18/// WAL-mode connection pool: one writer, N concurrent readers.

21/// `SqlAccess` trait bridge to `ConnectionPool`.
22pub mod sql_bridge;
23/// Per-substrate store implementations (entity, note, graph, event, text, vectors, sparse).

25/// Append-only NDJSON writer-timeout event sink (crate-internal).
26mod timeout_sink;
27/// Cross-process WAL-pin attribution sidecar (ADR-091 Amendment 2 Plank B).
28/// The sidecar write path (heartbeat/beacon) and identity primitives are
29/// portable; directory collection (`enumerate_live`/`housekeep_live`) is
30/// Unix-only — its only caller is the daemon's checkpoint task, and daemon
31/// mode itself requires Unix (see `khive-mcp/src/serve.rs`).
