HOW IT WORKS04 STEPS

Governance that writes its own audit trail.

Every request, verdict, and human decision logged to Band. No second database.

Agent sends an action request

No tools, no access. Intent only.

Warden evaluates policy

Real-time verdict. First-match wins. No LLM in the loop.

Human gates what policy can't

@mention in Band. Approve or deny in the UI. Decision logged immediately.

Band writes the ledger

Immutable trail. Every verdict, every human decision, one history.

THREAT MODEL03 SCENARIOS

The threat model made concrete.

COMPROMISED AGENT

Tries to write customer PII to an external path.

FORBIDDEN.

Not executed. Policy matched block-exfiltration before the tool was called.

ROGUE PAYOUT

Transfer instruction to an account not on the approved list.

BLOCKED.

Held at the airlock. Human notified. No funds moved.

LARGE TRANSFER

Agent requests a $50,000 wire. Policy threshold requires sign-off.

ESCALATED.

Paused at the gate. @compliance-team mentioned in Band. Waiting on human approval.

AIRLOCK IS LIVE

Your agents are already running.

The question is who's watching the door.
