/**
 * Day-3 live gate (half 2): fabricated-citation rejection.
 *
 * Drives the LegalRetrievalPort verifier with two payloads against the same
 * real chunk:
 *   - GENUINE quote (exact verbatim substring of chunk.text) → must be supported=true
 *   - FABRICATED quote (plausible-sounding but NOT in chunk.text) → must be supported=false
 *
 * Asserts both, prints the legal_claim_verifications row, exits non-zero on
 * regression. Runs against the local Postgres (DATABASE_URL must be exported).
