⚪grant_covenant(principal, agent_id, scopes, budget_minor, expires_at)
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(covenant_id, act_id, scope, amount_minor)
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.
