nx_etg.nx

nx_etg.nx -- Empirical-Truth Gamification substrate primitive. E1 first stone of NISHI_ETG_ROADMAP.md. Implements the substrate- wide doctrine [[feedback-physical-truth-over-published-docs-silicon- empirical-gamification]]: vendor docs are HYPOTHESES, the silicon is the truth. Every probe outcome records what the silicon actually did, classifies it against what the vendor claimed, and emits a ProvenanceLinked decision attestation. This brick is the TAXONOMY + ACCOUNTING + ATTESTATION layer. Real probes (E3 cpu / E5 gpu / E4 storage / E7 net) compose this.
