  title: Decide Decision Action Execution API
  summary: Decision protocol for state-changing software actions.
  description: Call Decide before products, agents, queues, billing systems, CRMs, or internal tools change state. The API returns a signed Decision Record v1 object with policy bundle attestation, evidence, action binding, replay, verification handles, portable Decision Packet v1 exports, simulation-only counterfactual analysis, cryptographic audit chains, Action Execution Receipts, Outcome Records, CRM Sync Records, predictive confidence, first-party policy pattern templates, policy effectiveness metrics, opt-in anonymized benchmarks, and explainable anomaly reports derived from reported outcomes.

      summary: Record a Decision Action Execution receipt
      description: 'Creates a hashed Action Execution Receipt linked to the original Decision Record and action binding. Keyed writes are atomically claimed: the same key plus the same canonical execution payload replays the original receipt, a concurrent request returns 409 in progress, and the same key plus a different payload returns 409 conflict. Authoritative storage and idempotency failures return 503 without acknowledging an untracked receipt.'
