about

nx_self_tune.nx -- LOCAL-ONLY DRIVER SELF-TUNE (X-DRV-F3). The privacy-preserving counterpart to the federated registry (X-DRV-F2): a NON-SHARING spore improves its own drivers using the SAME emitter + measurement, but the learnings NEVER leave the device -- no telemetry, no phone-home. It sweeps the candidate configs for each device on its OWN emu, measures emu-steps, and keeps the fastest as its tuned local registry. nx_self_tune [candidates_path] candidates : local_tune_candidates.tsv (deviceid <TAB> config_spec <TAB> config_bin) -> knowledge/registry/driver_registry_tuned_local.tsv (deviceid -> best local config + steps) -> knowledge/status/self_tune.log (SELFTUNE: per-device best, configs swept; NO shared writes) Touches ONLY local files (emit/run/registry/log). Sovereign, no gcc/.sh. license_tier: ORIGINAL
