## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability velaru-pre-finality-clearance-gate-56f43f0a -d '<json body>'
```

Example prompt: Before I send out this withdrawal to the user's wallet, run a pre-finality clearance check to make sure the operator license is valid and it's safe to execute — fail closed if anything looks uncertain.

## When to prefer this

Use this endpoint when you need a safety gate before executing any irreversible financial operation such as withdrawals, payouts, or binding commitments. Prefer this over simple balance checks when operator licensing hierarchy matters, when you need fail-closed behavior under uncertainty, or when compliance with a licensed-operator model is required.

## Known failure modes

- Revoked parent license causes all child payout requests to be blocked
- Uncertain or ambiguous state results in fail-closed denial
- Missing or invalid operator license returns authorization error
- Malformed transaction payload returns validation error
- Network or service unavailability defaults to deny/closed response

## How this service works

Gate clears withdraw, payout, and bind before execution. Fail closed under uncertainty. Parent license revoked blocks child spend. Licensed operators only.

## Output

Returns a clearance decision (approved or blocked) for the requested operation, along with a reason if blocked, license validity status, and any flags raised during pre-finality evaluation. Fails closed (denies) when the system cannot confidently confirm safety.
