| What makes it different | - Published weighted-vote rule with every vote shown by name instead of hidden percentages
- Reports disagreement honestly instead of blending signals into one number
- Automatic credit refund when an engine fails
- Full product access in free tier (not a limited teaser)
- Deterministic file evidence (C2PA, metadata) that outranks model votes
| - Deterministic verdicts from explicit state checks, not language model decisions
- No-cost deterministic testing; AI features are optional and separately metered
- Integrated sandbox testing and production guarding in one platform
- Idempotent and exactly-once action execution with retry safety
