mirra-core-contract

The frozen v1 interface of the MIRRA agent platform. Interfaces and schemas only — zero logic, zero dependencies. Every core component implements it; every deployment edge depends only on it.

AgentIdentity · Scroll · ExecutionIntent · DecisionRecord · VerificationResult
IdentityResolver.resolve_identity(principal)        -> AgentIdentity
MemoryStore.remember / recall / verify              -> signed Scrolls, verify-on-read
ExecutionAuthorizer.authorize(intent, identity)     -> signed DecisionRecord
CapabilityProvider.enrich_identity / verify_epistemic   (optional, runtime-injected)

Rules baked into the contract

• Frozen. This is v1. It never breaks without a major version bump; the freeze-guard tests (tests/test_contract_frozen.py) fail on any signature or schema drift.
• Fail-closed. Missing engine, missing signing secret, or failed verification means deny/reject — never silent degradation.
• Real cryptography. verified: true always reflects an actual signature check, never a proxy like "the record exists." Signed artifacts declare their scheme (hmac-sha256 for same-owner memory, ed25519 for distributable proofs).
• Generic vocabulary. Capability providers are named generically; the contract is the only shared vocabulary between public packages and any private implementation. scripts/check_public_private_boundary.py is the CI gate that keeps it that way.
