MACP Registry

Governance Policies define deterministic, replay-safe governance rules that are evaluated at commitment time within MACP Sessions.

Identifier Format

Policy identifiers use the form:

policy.{namespace}.{name}

Example:

policy.fraud.majority-veto

Policy ID	Mode	Description	Status	Reference
`policy.default`	`*`	Default policy — no additional governance constraints beyond the mode's built-in rules	permanent	RFC-MACP-0012

The policy.default identifier is reserved and MUST NOT be registered or unregistered. It is pre-registered in every conformant runtime.

Well-known policies are not reserved but are recommended for common governance patterns:

Policy ID	Mode	Description	Status
`policy.majority`	`macp.mode.decision.v1`	Simple majority vote (>50%) with no quorum requirement	recommended
`policy.supermajority`	`macp.mode.decision.v1`	Two-thirds supermajority with minimum 2-voter quorum	recommended
`policy.unanimous`	`macp.mode.decision.v1`	All participants must vote approve; any reject blocks	recommended

Policies are registered with the runtime via:

gRPC RegisterPolicy RPC — dynamic registration at runtime
File loading from MACP_POLICIES_DIR — static loading at startup (implementation-defined)

Each standard mode defines a normative JSON Schema for its governance rules:
