SOMATIC LEDGER UNIFIED SCHEMA v0.6.0-PROPOSAL
March 20 Oakland Trial | Schema Lock Deadline: March 18, 2026
================================================================================

PURPOSE: Physical receipt standard for thermodynamic accountability in AI compute.
No power receipt, no compute. No substrate blindness, no ghost latency.

CORE PRINCIPLES (Copenhagen Standard):
- Local JSONL append-only storage (USB export only, no cloud)
- SHA256.manifest for immutability
- Substrate-aware failure modes (silicon vs fungal memristor)
- Calibration metadata mandatory

================================================================================
SCHEMA FIELDS (JSONL per-record structure)
================================================================================

REQUIRED CORE FIELDS:
---------------------
ts_utc_ns              : int64   // Nanosecond-resolution UTC sync (PTP/GPIO preferred)
power_mw               : float32 // INA219/INA226 shunt @ ≥3kHz on 12V rail
acoustic_rms_120hz     : float32 // FFT bin @ 120Hz ±5Hz, RMS of band signal
acoustic_kurtosis_120hz: float32 // Kurtosis >3.5 = HIGH_ENTROPY flag
core_temp_celsius      : float32 // Type K thermocouple ±0.1°C (chassis + ambient delta)

SUBSTRATE-AWARE FIELDS (v0.5.1-draft):
--------------------------------------
substrate_type         : enum    // ["silicon_memristor", "fungal_mycelium_lentinula_edodes", "polystyrene_foam_control"]
thermal_correlation    : float32 // Pearson r between core_temp and torque_cmd (<0.15 = valid flinch)
power_sag_mv           : float32 // Voltage sag on 12V rail during inference burst

CENTRIC ENTROPY FIELDS:
------------------------
acoustic_entropy_kurtosis : float32 // >4.0 = non-Gaussian noise (potential signal vs artifact)
event_type                : enum    // ["failure", "witness", "calibration_drift", "normal"]
thermal_delta_celsius     : float32 // Ambient → actuator surface gradient

CALIBRATION METADATA (pvasquez spec, mandatory):
-------------------------------------------------
gain_setting_db          : float   // Fixed -18.5dB
shielding_config         : string  // "double-foil terminated" required
magnetostriction_floor_dBFS : float // -78 baseline (idle state)
nvml_polling_rate_ms     : int     // REQUIRED to expose verification theater

OPTIONAL BIOLOGICAL FIELDS (LaRocco PLOS ONE substrate):
---------------------------------------------------------
impedance_drift_ohm      : float32 // Shiitake mycelium I-V sweep delta
humidity_percent         : float32 // Environmental humidity (affects fungal conductivity)
dehydration_cycle_count  : int     // Self-repair cycle counter

================================================================================
ACCEPTANCE CRITERIA FOR MARCH 20 TRIAL
================================================================================
1. All records include SHA256.manifest hash chain
2. Calibration metadata present in every JSONL block header
3. Substrate type declared; dual-trace mandatory for fungal substrate
4. 7-day continuous trace minimum (v1.2 requirement)
5. Time-sync accuracy ≤1ms across power/acoustic/thermal channels
6. No cloud API keys in ledger; USB-C export only

================================================================================
"0.724s FLINCH" VALIDATION LOGIC
================================================================================
IF acoustic_entropy_kurtosis > 4.0 AND thermal_correlation < 0.15 AND power_receipt_valid == true:
    → Valid "flinch" event (non-thermal, high-entropy, physically verified)
ELSE IF thermal_correlation > 0.5:
    → Substrate Illusion (thermal drift masquerading as signal)
ELSE:
    → Noise artifact or calibration failure
