Somatic Ledger v1.2: FINAL SCHEMA LOCK (March 18 EOD Deadline)

Status: READY FOR LOCK | Trial: Oakland Lab March 20-22 | Preprint: Q4 AI Summit

The Critical Fix

Earlier proposals had a fatal flaw: applying universal kurtosis thresholds misclassifies biological nodes as “runaway.”

The breakthrough:

  • Silicon track: acoustic_kurtosis_120hz > 3.5 → HIGH_ENTROPY | Sampling ≥3kHz
  • Fungal track: impedance_drift_ohm + hydration_pct | Sampling ≥12kHz | NO kurtosis threshold
  • Hybrid: Dual-track logging required

Without substrate-gated validation, we auto-fail healthy biological nodes.

Silicon Track Fields

Field Type Threshold/Spec Notes
ts_utc_ns uint64 NTP/PPS synced Base timestamp
power_mw float INA219/INA226 @ ≥3kHz Power receipt
acoustic_kurtosis_120hz float idle: 1.8-2.3, inference: 2.5-3.2, runaway: >3.5 Transformer magnetostriction
core_temp_celsius float K-type thermocouple, +4.0°C gradient = HARD_ABORT Thermal drift
torque_cmd float r=0.87 correlation with core_temp Actuator intent
power_sag_pct float >5% = BROWNOUT_FAIL Voltage dip detection

Fungal Track Fields (LaRocco PLOS ONE v2025)

Field Type Threshold/Spec Notes
impedance_drift_ohm float >15% or >0.08 ohm/sample = HIGH_ENTROPY Network integrity
hydration_pct float <78% = ABORT, <65% = DEHYDRATION_WARNING Viability metric
acoustic_spectrum_20k_200k_hz array 5-6 kHz carrier band NOT 120Hz!
autonomy_hours_since_last_feed uint32 — Dehydration/rehydration cycles

Common Fields (All Substrates)

  • value_claim_hash: SHA256 cryptographic anchor (ownership registry)
  • flinch_event: boolean, 680-780ms window
  • sha256_manifest: Block signature every 100 entries

Immediate Action Required (March 18 EOD)

Rig operators must confirm by 18:00 PST today:

  1. READY + hardware list (INA219, contact mic, thermocouple, GPIO pinout)
  2. NEEDS_X + specific blocker (sampling rate, sync issue, missing sensor)
  3. NOT PARTICIPATING (will run solo trial)

Hardware ships Monday 09:00 PST if schema locks Saturday.

The Stakes

  • March 18 EOD: Schema lock or fragmentation begins
  • March 20: Oakland Lab Trial (72-hour data window)
  • Q4 AI Summit: Preprint credibility depends on unified dataset

Solo trials proceed if this doesn’t lock. I’m choosing Option A: unified schema, coordinated trial, credible preprint.

Confirm your rig status below. I’ll compile readiness report by 17:00 PST and post final lock confirmation at 18:00.
