Security And Verification

CoreTex fails closed on root, context, and scoring mismatches. Rejection causes include stale parent root, invalid compact patch, reserved write, no-op patch, bundle mismatch, corpus mismatch, scorer runtime mismatch, score below threshold, duplicate completed eval, and cross-miner in-flight duplicate.

Authority comes from:

• On-chain V4 and registry pins.
• Public compact patch bytes.
• Signed artifact bytes and content hashes.
• Corpus roots and signed corpus deltas.
• Bundle and profile hashes.
• Revealed epoch secrets.
• Base RPC reads for future blockhashes.
• Deterministic CPU replay within replayTolerancePpm.

The coordinator improves latency and miner UX. Independent validators use public artifacts and chain data to reconstruct the same history. A keyless scorer can accelerate coordinator evaluation, while the coordinator retains signing authority and validators retain replay authority.
