API PROPOSED

Versioned request and response contracts. No hosted endpoint exists yet. The sandbox below runs the same decide() function in your browser against the fixture.

The static state record, artifact index, non-claims, HOLD record and experimental Python report are downloadable JSON files, not responses from the proposed endpoints below.

Endpoints

POST /v1/decisions
POST /v1/decisions/{id}/reassess
GET  /v1/receipts/{id}
POST /v1/crosswalks/{version}/evaluate      # PROPOSED
POST /v1/research/spectral-runs             # PROPOSED, research only
GET  /v1/research/spectral-runs/{id}        # PROPOSED, research only

Every decision response includes outcome, reason_codes, fixture_or_domain, policy_ref, mapping_ref, invariant_ref, signature_verification, authority_verification, evidence_verification, valid_time, record_time, receipt_ref, reassesses and decision_digest. Schema: decision-response.v0.json.
Research endpoints return experimental outputs and never a warrant. There is no /zeta-zeros endpoint, and none is a governance dependency.
MCP, A2A, DID/VC, metering and settlement are possible later adapters. None is implemented, and none is a prerequisite.

Errors (proposed contract)

The sandbox exercises only 200 and 400. The other codes are specified for a future hosted API.

HTTP	Code	Meaning
200	—	A determination was made, including HOLD. HOLD is a result, not an error.
400	`MALFORMED_PROPOSAL`	Request body failed schema validation. No determination is recorded.
404	`UNKNOWN_RECEIPT`	No receipt with that reference.
409	`PRIOR_NOT_FOUND`	Reassessment names a prior determination that does not exist.
503	`FIXTURE_UNAVAILABLE`	Referenced fixture or policy material cannot be retrieved.
