Policy and Budget Controls
Sigillum should use one shared policy model across personas: recommendation thresholds, optional score ceilings, and spend caps before payment happens.
Risk gates
The minimum serious risk gate set is recommendation threshold plus optional maximum Sigillum Risk Score.
- Always stop on `block`
- Optionally fail or pause on `warn`
- Optionally enforce a maximum risk score
Budget gates
The quote is the natural budget checkpoint. Spend policy should be able to stop a risky action before x402 payment happens.
- Max spend per action
- Daily or monthly caps
- Persist why a quote was skipped or blocked by budget
