Limits
| Limit | Why it matters | Status |
|---|---|---|
| Unpinned verification proves nothing | Anyone can build a self-consistent receipt with four keys of their own | CLI refuses without a pin (live); server pins by default (deploy pending) |
| Seconds, not milliseconds | 2.6 s per digest: fine for evidence, wrong for a request hot path | Inherent to one consensus round per call |
| One cloud provider | Four regions, one company: not independent operators | Open |
| All validators are operated by us | Byzantine tolerance protects against a faulty node, not against the operator of all four | Open: independent validators would fix it |
| No passed 72-hour soak | Long-run stability is not demonstrated | Open |
| Health flaps | A degraded cluster has no fault margin | Open |
| Time is not certified | issued_at is the gateway's word | Inherent; use an RFC 3161 timestamp if you need one |
| No published price, no SLA | Not yet a commercial service with guarantees | Open |
| No independent review | Every test here is ours | A paid independent review is planned |
FIRME AI CORPORATION · CAIN-42 is a Byzantine trust fabric. Numbers marked "our own check" were run by us, not by an independent party. Nothing on these pages is a certification.
