 * Fix-invariants audit — guards against silent regression of the recent

 *
 * Each entry pins one or more substrings/regexes that MUST exist in a
 * specific source file. The substring is the load-bearing line from the
 * fix — if a refactor accidentally removes it, the bug returns silently
 * (no test failure, just wrong runtime behavior).
 *
 * This is intentionally a presence-check (not a behavior test). Behavior
 * is covered by the dedicated audits (audit-vector-dim, audit-hook-
 * handler-prompt) and unit tests; this script is the cheap last-mile
 * guard for fixes whose dedicated test wasn't worth writing alone.
 *
 * Usage:
 *   node scripts/audit-fix-invariants.mjs           # exit 1 on any miss
 *   node scripts/audit-fix-invariants.mjs --json    # machine-readable report
