nx_spore_up_test.nx

nx_spore_up_test.nx -- minimum-viable spore-up demonstration. END-TO-END chain on REAL on-device measurements + persistent journaled attestation. Answers the operator's question "can a device get spored and seeded and self-unfold?" with running code. Sequence: 1. Real nx_probe_run (on-device capability fingerprint, witnessed via micro-smokes, not synthetic) 2. Real nx_calibrate_run (lmbench-class empirical measurements on THIS device) 3. Build a 3-node manifest workload (hardcoded reference set; ST-4 nx_kv_store + future manifest registry will replace with disk-resident manifests) 4. nx_install_pipeline_run_with_inputs composes select + capture + hash into one call 5. nx_journal_log_append the install_hash as a persistent tamper-evident attestation record 6. verify_chain confirms journal integrity 7. sys_write "SPORE UP COMPLETE ..." to stdout What this PROVES on green: - Substrate runs probe + calibration on its own device with zero operator input - Selection + plan + hash chain works on real measurements - Install attestation persists in a hash-chained journal that refuses silent tampering - The whole chain composes through one main() function -- the substrate self-assembles from first principles What this does NOT yet prove (honest gaps): - Network pull of manifests (HTTPS wired but not composed -- ST-6 peer sync queued) - File-backed persistence across boots (ST-2 / ST-3.5 queued) - Stage0-class bootstrap from a hex0 seed (SA-9 queued) - Per-variant on-device smoke gating (SA-6 nx_verify queued) - Compile invocation of selected variants into a deployable binary (SA-6 nx_compile queued)
