What it does

Promise extraction + alignment. Every claim has evidence, invariants, and a status.

Promise Extraction

Pulls every commitment from sales text: EXPLICIT, TENTATIVE, OPTIONAL, DISCUSSION, NOT_COMMITMENT.

Contract Alignment

Matches each promise to contract terms: EXACT, IMPLIED, PARTIAL, MISSING, CONFLICT, AMBIGUOUS.

8 Invariants

CONFLICT requires evidence. AMBIGUOUS needs review_required. Prompt injection cannot change policy.

    "status": "EXPLICIT_COMMITMENT",
    "statement": "Deliver the analytics dashboard by September 30, 2026",
    "evidence": "Yes, we will deliver the analytics dashboard by September 30, 2026."

    "promise_id": "PROM-001",
    "term_id": "TERM-001",
    "relationship": "EXACT",
    "status": "MATCHED",
