Scientific Expansion Plan — Biophysical Field Correlation

Hard-science experiments to test correlations between biological EM activity and external electromagnetic field states captured by Watcher / PAX V (IC, ACS-SI). All accordions start closed by default.

1 Purpose & Mission Alignment

This program extends Watcher’s analog collection into biophysical field correlation: testing whether time-locked patterns in human electromagnetic activity (non-invasive sensors) show statistically meaningful relationships with concurrently measured external EM environments and communications bands. The outcome is a defensible evidence base for or against weak, structured correlations relevant to sensing, attribution, and pre-digital anomaly detection.

  • Quantify phase-locked or coherence-based relationships between EEG-band activity and external EM spectra
  • Evaluate predictive information in biological signals for imminent external signal transitions (e.g., burst onset, modulation change)
  • Map spatial EM gradients vs. biological responses in shielded vs. ambient conditions

Operational value: If correlations exist, Watcher can fuse bio-EM context into electromagnetic situational awareness and threat pre-indication models without relying on subjective reports.

2 Testable Hypotheses

  1. H1 — Coherence Coupling: During controlled EM stimuli, band-limited increases in EEG/MEG-proxy coherence will co-vary with the external field’s instantaneous phase stability.
  2. H2 — Predictive Lead: Biological EM features (phase-amplitude coupling, microstate transitions) contain measurable lead information (Δt > 0) about external EM state changes beyond chance.
  3. H3 — Shielding Differential: Signal relationships degrade or vanish under mu-metal shielding, confirming dependence on physical field pathways rather than instrumentation artifacts.
  4. H4 — Individual Baselines: Within-subject baselines reduce variance and yield higher effect detectability than between-subject pooling.

3 Measurement Architecture (Add-Ons to IC / ACS-SI)

  • Core acquisition: IC / ACS-SI at 52 GS/s, voltage-current pairs, deterministic micro-timestamps (PTP + 1PPS)
  • Bio-EM front-end (non-invasive): 32–64ch EEG-class differential amplifiers (DC-coupled, <1 µV_rms noise), dry/wet electrodes; optional OPM-based micro-magnetometers (low-field, room-temp) where permissible
  • Ambient EM sensors: Wideband electric & magnetic probes (kHz → multi-GHz), near-field loops, spectrum-tunable front-ends synced to IC timebase
  • Shielding & fixtures: Mu-metal enclosure for A/B trials; Faraday tent; non-conductive chair; fiber-optic isolation for data links
  • Synchronization: Common disciplined oscillator & 1PPS distribution; timestamp unification into IC’s master clock
Channel GroupRate / BWNotes
IC Analog (tap)52 GS/sPrimary field state capture (mission bands)
Bio-EM EEG x641 kS/s – 8 kS/s0.05–200 Hz, 24-bit ADC, high CMRR
OPM µ-mag (opt.)1–5 kS/spT sensitivity, low-field mapping
Ambient RF probesUp to GS/sBand-selective, down-conversion when needed

i Integration Notes
  • Bio-EM ADCs are clock-slaved to the IC timebase; all streams share a unified timestamp domain
  • Fiber or optical USB extenders ensure ground isolation; electrode leads are twisted-pair, shielded, and strain-relieved
  • All analog front-ends are pre-characterized (gain, phase, noise) to enable deconvolution in analysis

4 Experimental Protocols

A Protocol A — Passive Ambient Correlation (Baseline)
  1. Seat participant; apply EEG (and optional OPM) in comfortable posture
  2. Record 20-min resting state (eyes open/closed blocks) with concurrent ambient EM capture
  3. Repeat inside mu-metal enclosure (A/B) with identical timing
  4. Mark micro-events (eye blinks, movement) via IMU to regress in analysis

Goal: establish null distributions for correlation metrics and shielding differentials.

B Protocol B — Controlled EM Stimulus (Band-Locked)
  1. Inject calibrated external EM patterns into a dummy load / shielded radiator (safety-compliant), time-stamped
  2. Stimulus families: steady tone (phase-stable), chirps, pseudo-random BPSK/QPSK symbol streams, on/off bursting
  3. Block design (30–60 s on/off) randomized; participant relaxed and blinded to stimulus timing
  4. Record inside and outside shielding; additional sham runs (no output) to test expectation effects

Goal: detect phase/coherence entrainment and onset-locked responses across bio-EM channels.

C Protocol C — Predictive Transition Task
  1. Define external EM regime switches (e.g., modulation change every 8–15 s, jittered)
  2. Compute online features (low-latency) from bio-EM; log predictions vs. actual switch timestamps
  3. Assess lead/lag distributions; cross-validate with offline high-resolution analysis

Goal: evaluate H2 (predictive lead) under blinded, randomized changes.

D Protocol D — Spatial Gradient Mapping (Exploratory)
  1. Move ambient probes along predefined paths; maintain stationary participant
  2. Map correlation strength vs. probe position to test near-field geometry effects

5 Data Pipeline & Storage

  • Ingest: All streams land on IC using a common timebase; triggers stamped on rising edges
  • Pre-processing: Line noise removal (50/60 Hz + harmonics), robust detrending, ICA/SSP for blink/muscle artifacts, band-limited copies (δ/θ/α/β/γ)
  • Feature stacks: Instantaneous phase/amplitude (Hilbert), multi-taper spectral power, phase-amplitude coupling (PAC), microstate segmentation, wavelet coherence (bio↔external)
  • Metadata: Device calibration curves, electrode maps, shielding state, stimulus scripts, IMU traces
  • Storage: Forensic ring buffers with lossless slices to RAID; AES-256 at rest, Kyber for key exchange
i Deterministic Timing

Grandmaster clock discipline verified before and after sessions (Allan deviation checks). Jitter budgets recorded; any run exceeding thresholds is flagged and excluded.

6 Statistical Analysis & Detection Logic

  • Coherence & PLV: Bio↔external magnitude-squared coherence and phase-locking value with permutation tests
  • Causality & Lead/Lag: Time-resolved Granger, transfer entropy, cross-correlograms on feature streams
  • Onset Responses: Event-related synchronization/desynchronization (ERS/ERD) around stimulus edges
  • Predictive Modeling: Regularized logistic / gradient boosting on pre-onset windows; AUROC vs. shuffled labels
  • Reliability: Within-subject mixed models; false discovery control across channels/bands

i Preregistration & Blinding

Stimulus schedules are generated and sealed before sessions. Analysis scripts (hash-locked) are committed prior to unblinding to prevent researcher degrees of freedom from inflating effects.

7 Controls, Artifacts & Negative Tests

  • Sham hardware: Identical cabling with terminated inputs to detect instrumentation leakage
  • Distance controls: Increase sensor-to-participant distance to probe fall-off relationships
  • Lead swaps: Reverse channel mapping to confirm analysis isn’t label-driven
  • Motion regressors: IMU-based regressors ensure muscle/movement aren’t mistaken for correlations
  • Environment replay: Use IC replays to replicate external fields without participant present

8 Ethics, Safety & Data Governance

  • Non-invasive only: EEG-class electrodes and external magnetometers; no stimulation of participants
  • IRB / oversight: Consent, minimal risk classification, right to withdraw, confidentiality guarantees
  • Compliance: Electromagnetic emissions within permissible exposure limits; shielded loads preferred
  • Security: Compartmentalized access; role-based controls; cryptographic audit of data lineage

This plan evaluates physical correlations; it does not claim mind-reading or medical diagnosis.

10 Risks, Mitigations & Exit Criteria

  • False correlations: Mitigation: strict shielding, shams, preregistration, permutation controls
  • Weak effects: Mitigation: within-subject designs, longer blocks, richer features (PAC, microstates)
  • Instrumentation leakage: Mitigation: optical isolation, terminated shams, environmental replays
  • No detectable effect: Exit: publish negative result internally; de-scope bio-EM fusion and retain IC advances (timing, shielding, ambient mapping) for other missions
