HumanMirror M2M Core Services
Three separately published contracts for the M2M core: Sanitize Shield (indirect prompt-injection quarantine with a signed Cleanliness Proof), M2M Payload Normalizer (canonical JSON + stable SHA-256 digest) and the Probabilistic Consensus Oracle (weighted log-odds validation of two contradictory agent signals). Each has a free discovery GET, three free calls per 24 hours, then 0.001 USDC via x402; all three are also inside the x402 contract.
