Human decides and executes
AI recommends, human approves each action
AI recommends, human approves batches
AI acts, human can override
Full autonomous execution
| Level | Name | Description | Approval Model | Who Can Enable |
|---|---|---|---|---|
| L0 | Manual | Human decides and executes | None required | Any operator |
| L1 | Recommend | AI recommends, human approves each action | Per-action approval | Any operator |
| L2 | Batch Approve | AI recommends, human approves batches | Batch approval | Senior operator |
| L3 | Supervised | AI acts, human can override | Async oversight | Admin + L2 approval |
| L4 | Autonomous | Full autonomous execution | Explicit unlock + CISO sign-off + MFA | C-level only |
Every ADEF action is recorded in Chronicle - an append-only ledger where each record contains the Blake3 hash of the previous record (hash chain) and an Ed25519 signature from a FIPS 140-2 Level 3 HSM-backed signing key. Records cannot be altered or deleted without breaking the chain. Tamper detection is instant and cryptographically provable.
