/**
 * Vector-index dimension audit (regression guard for #1947 / #1942 / #1952).
 *
 * Issue #1947 root cause: the bundled SQL schema initialises the `default` and
 * `patterns` rows in `vector_indexes` with `dimensions = 768`, but the
 * default ONNX embedding model (`Xenova/all-MiniLM-L6-v2`) produces 384-dim
 * vectors. HNSW rejects every insert with the mismatched dim, so
 * `memory_store --vector` succeeds but `memory_search` always returns 0 hits.
 *
 * The fix is purely a number change in 11 `.swarm/schema.sql` files plus the
 * inline schema string in `v3/@claude-flow/cli/src/memory/memory-initializer.ts`.
 * This script blocks the next regression: every `INSERT ... INTO
 * vector_indexes (id, name, dimensions) VALUES ('default'|'patterns', ..., N)`
 * must have `N === EXPECTED_DIM` (currently 384 — track the default model).
 *
 * Anything caught here would silently break every "memory_search returns 0"
 * scenario in the bug cluster: #1947, #1942, #1952 (Windows), and the
 * downstream bridge-import issues that imported 384-dim vectors into 768-dim
 * indexes (#1941, #1940).
 *
 * Usage:
 *   node scripts/audit-vector-dim.mjs           # audit, exit 1 on mismatch
 *   node scripts/audit-vector-dim.mjs --json    # machine-readable report
