Claims-Evidence-Attestation (CEA) system with status transitions
(proposed→supported→challenged→superseded), evidence linking
(supports|challenges), and attestations (endorse|dispute|abstain) with
claim_strength materialized view.
Intent matching with need/offer/possibility types, governance_fit
overlap scoring, and complementary type matching.
Commitment lifecycle state machine (proposed→verified→active→
evidence_linked→redeemed, disputed↔resolved) with evidence linking
and enforced transitions.
