BotCheck — Per-request AI-traffic integrity attestation for adtech

Deterministic heuristic classification (no ML, same input → byte-identical output) of request headers + behavioral signals into human | agent | bot | unknown, plus an Ed25519-signed batch impression-integrity certificate and a SEED IP/UA reputation database. Transparent by design — the code IS the honesty claim.
