What the record actually supports
Verdict: the claim that this packet contains only a 2-hour and a 20-day cycle does not survive the audit.
- ~2 hoursnot periodic
- The 2-hour lag retains some memory (r=0.184), but a repeating 2-hour sine is not detected (R²=0.014%, p=0.801).
- 24.848 hourscandidate
- The strongest recurring component explains 8.73% of variance (scan-wide p=0.001) and stays within 24.80–24.91 hours under stability checks. Its biological, behavioral, or device source is unresolved.
- ~20 daysunsupported
- A fixed 20-day sine is not supported (p=0.495), worsens blocked prediction, and has only 1.95 repeats in this record. The window is too short to exclude a slow cycle.
- Other cyclesbounded result
- No remaining 0.5–36-hour peak passed after candidate removal (p=0.588), and no 3–30-day candidate passed its null. That means “not detected here,” not “absent.”
Input cleaning. Of 6,889 unique fresh HR readings, 1,129 readings from 20–34 bpm — including 171 at exactly 20 bpm — were treated as PPG dropout artifacts and excluded. The audit used 5,760 readings across 40 usable daily means; gaps were not interpolated.
Claim boundary. The null tests retain the real observation slots. This describes one wearable packet; it does not diagnose a person or calibrate the synthetic C model above.
Model scope and build details
Scope
This is a systems sketch, not a digital person. It is useful for inspecting feedback, conservation ledgers, and controlled counterfactuals.
Implemented
- Deterministic fixed-step C state machine
- Synthetic kcal and mL conservation ledgers
- Seeded action competition and body-event queues
- Five controlled schedule scenarios
Not claimed
- Biological or clinical validity
- Diagnosis or treatment response
- Individual calibration or prediction
- Cross-platform floating-point identity
