/**
 * Bridge LadybugDB schema for cross-repo Contract Registry.
 * Separate from per-repo schema in cgdb/schema.ts.
 */
/**
 * Version of the bridge.cgdb schema below. `openBridgeDbReadOnly` compares
 * this against `meta.json`'s version field and returns `null` on mismatch,
 * which trips the caller into either the JSON fallback path or a fresh
 * `group sync` that rebuilds `bridge.cgdb` from scratch.
 *
 * Migration contract for contributors bumping this constant:
 *   1. Bump the number (e.g. `1` → `2`).
 *   2. Update the DDL below to match the new schema.
 *   3. DO NOT attempt an online migration in this file — the version gate
 *      is intentionally a "discard and re-sync" strategy for V1. An old
 *      bridge.cgdb whose version doesn't match is treated as opaque and
 *      rebuilt by the next `group sync`.
 *   4. If online migration becomes necessary (e.g. when groups accumulate
 *      large amounts of embedding data), add a migration path as a
 *      separate `bridge-migrations.ts` module rather than bloating this
 *      file — keep schema and migration concerns separate.
