🟢 読み取り専用🟡 書き込み🔴 削除⚪ 不明
⚪verify(action_type, action_payload, agent_id, policy_context, template_id, ...)

Verify an action against policy bounds before executing it. Returns ALLOW (proceed), CONSTRAIN (proceed with modified values; emitted on the wire as the legacy value CLAMP - both refer to the same verdict, CONSTRAIN is the public name), or DENY (stop). Every verification is recorded in a hash-chained provenance ledger. Cost: $0.01 per call.
