Assurance Tiers
Flash, Pro, Lightning, evaluate_latest, and optional cascade.
Select assurance_tier explicitly on every evaluate call:
| Tier | Behavior | Credit multiplier |
|---|---|---|
flash | Critic k=1 | 0.5× |
pro | Critic k=2 strict-union | 1.0× |
lightning | 1.7B zero-decode path | 0.5× |
evaluate_latest
Pass evaluate_latest: true to pin the platform’s current recommended production scorer without hard-coding a model string.
Opt-in cascade
assurance_cascade (when enabled for the tenant) may escalate Flash → Pro on uncertainty — never silently downgrade Pro.
