grant_covenant
Grant an agent a covenant: an explicit lease of authority. scopes support wildcards ('payments.*', '*'); budget_minor is the total spend ceiling in minor units; expires_at is ISO-8601. Returns the covenant_id.
check_act
Check (and if allowed, record) a proposed act against a covenant. Deny-by-default. Idempotent on act_id — retries never double-consume budget. Every check lands on the audit chain.
revoke_covenant
Revoke a covenant immediately and terminally. All subsequent checks deny.
covenant_status
Current state, consumed/remaining budget, and check count.
verify_audit
Verify the tamper-evident audit chain of allowed/denied acts.
list_covenants
List covenants, optionally filtered by state (ACTIVE|REVOKED|EXPIRED) and/or the bound agent.
describe_agent
Fleet-standard self-description.
