CAIN-42 CAIN StudioThe 11 checks
| # | Check | Passes only if |
|---|---|---|
| 1 | 🛰️ Live Byzantine cluster | 4 validators, 4 regions, quorum 3, and a health reading under 15 minutes old |
| 2 | 📜 A real quorum certificate verifies | a receipt signed by 3 of 4 replicas checks out against today's pinned membership |
| 3 | 🧨 Five forgeries are rejected | digest swap, sequence change, one flipped signature bit, one vote removed, wrong pin |
| 4 | 🔐 Tamper-evident and offline-checkable | one changed character changes the hash and the server refuses it; offline verifiers import no CAIN code |
| 5 | 🧠 AETHER-33 memory: 33 invariants | run against a real SQLite store on each request; an exception counts as a failure |
| 6 | 🚫 Fail-closed | empty, malformed and keyless requests never become a yes |
| 7 | 🛡️ CODEGUARD | 11 destructive commands DENY, 5 everyday commands ALLOW |
| 8 | 🧮 Deterministic math | DriftGuard, FlowGate, FairGate, LiftGate, FrontierGuard: same input, same answer |
| 9 | 💳 CAINPay | spelling tricks do not dodge a merchant block (known gaps listed on the page) |
| 10 | 🔒 Security basics | HSTS, strict CSP, no framing, other visitors' records private |
| 11 | ⚓ Outside anchor (new) | the 4-region proof chain head, re-hashed in your browser, matches what was logged in Sigstore Rekor |
A check passes only when every line in it passes. A check that makes no assertions, or throws an error, shows FAIL.
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.
