/**
 * Canonical trajectory.db schema definition (PRI-774; SPEC:
 * docs/specs/trajectory-data-plane-single-truth.md).
 *
 * Single source of truth for the schema applied by BOTH build paths:
 * - openclaw-plugin applyTrajectorySchema() → Profile B/C (views: true)
 * - principles-core ensureTrajectorySchema() → Profile A (views: false,
 *   pain-record path)
 *
 * Ownership:
 * - owns: CREATE TABLE/INDEX/VIEW statements, column-migration blocks, the
 *   evolution_tasks column backfill, TRAJECTORY_SCHEMA_VERSION and
 *   TRAJECTORY_TABLES declarations.
 * - does NOT own: path resolution, directory creation, connection lifecycle,
 *   WAL/pragmas, schema_version ROW writes (TrajectoryDatabase.initSchema and
 *   initTrajectorySchema keep that), v_daily_metrics (plugin migrateSchema),
 *   governance_* tables (host-runtime stores).
 *
 * Zero pathways are abolished: both paths keep their exact pre-PRI-774
 * behavior; only the definition-text copies converge (SPEC v3, Owner-approved).
