## 1. WHAT THIS IS

The Continuity Lab researches whether continuity — the unbroken chain of sovereign existence — can be made a verifiable cryptographic property. The MyShape Protocol is our first publication: a motion-signature system that verifies two sensor observations describe the same physically embodied entity.

Core thesis: Identity verification answers "Who are you?" Continuity verification answers "Are you still you, across time?" The internet has the first. It has never had the second.

## 2. RFCs (FORMAL SPECIFICATIONS)

### RFC-0001: Motion Signature Format
https://www.myshape.com/research/notes/004-motion-signature-rfc

Defines the complete motion verification pipeline:
- Presence Entropy Score (PES): 4D feature extraction (micro-timing variance, noise residual, frequency entropy, biological perturbation). PES = min(1, 0.25·MTV + 0.25·NR + 0.30·FE + 0.20·BP)
- Jerk Peak Detection: MAD-based dynamic threshold (τ = median(|j|) + 2×MAD(|j|), floor 0.15 m/s³). 150ms refractory period.
- Cross-Modal Temporal Matching: IMU jerk peaks matched to camera direction changes within ±500ms window, 90° direction tolerance.
- Challenge-Response Extension (EE-003): 3 rounds, randomized directions, jittered timing (±1000ms). Evidence sufficient when ≥2/3 rounds pass.

### RFC-0002: Continuity Proof Format
https://www.myshape.com/research/notes/006-continuity-proof-rfc

Defines the proof infrastructure:
- EvidenceReceipt: JSON-serializable object with sessionId (UUIDv4), timestamp, verdict, confidence, engineEvidence[], evidenceDigest (SHA-256), previousReceiptHash, cfcResults[]
- Hash Chaining: R₁ → H(R₁) → R₂ → H(R₂) → R₃. Chain Integrity Score (CIS) = valid links / total links.
- CFC Catalog: 8 Continuity Failure Conditions with severity levels and detection algorithms.
- Verification Policy: acceptThreshold (0.70), rejectThreshold (0.35), IMU_ONLY_CAP (0.65), escalationEngines ([EE-003])

## 3. CONTINUITY FAILURE CONDITIONS (CFC)

| ID | Name | Severity | Detection |
|----|------|----------|-----------|
| CFC-001 | Entropy Drop | HIGH | PES drops >50% between consecutive sessions |
| CFC-002 | Sensor Profile Change | HIGH | IMU noise profile changes beyond calibrated variance |
| CFC-003 | Temporal Gap | MEDIUM | Inter-session interval exceeds configured maximum |
| CFC-004 | Location Discontinuity | MEDIUM | Session locations physically impossible to traverse |
| CFC-005 | Causal Inversion | HIGH | Camera direction change precedes IMU jerk by >250ms |
| CFC-006 | Challenge Non-Response | HIGH | Entity fails to respond within capture window |
| CFC-007 | Challenge Mismatch | HIGH | 0/3 rounds match challenge direction |
| CFC-008 | Predictability | MEDIUM | Motion too consistent (angleVar<50, magVar<0.05) |

CFC-005 validation: Activated 13 times in 276 independent-device runs, 0 times in 50 single-device runs. Confirms genuine temporal causality detection.

## 4. EVIDENCE ENGINES

| Engine | Name | Type | N | Pass Rate | Key Finding |
|--------|------|------|---|-----------|-------------|
| EE-001 | Presence Entropy Score | Passive | — | 100% floor | Living entities distinguishable |
| EE-002 | Cross-Modal Causal Coupling | Passive | 316 | 58% | Temporal alignment 100% independent |
| EE-003 | Gyroscope Challenge | Active | 200 | 59% | 2/3 rounds sufficient |
| VS-001 | Dual-Engine Pipeline | — | 60 | 93% | Escalation reliable |

Total: 576 experimental runs. All data, diagnostics, and failure reports public.

## 5. EXPERIMENTAL FINDINGS

### Temporal Alignment: 276/276 = 100%
IMU jerk peaks and camera direction changes consistently match within ±500ms across independent devices. This is the central experimental result.

### Tracker Iteration (PE-001)
Three generations of camera motion tracking:
1. Pixel differencing: 27% pass, 38 fps
2. Color-blob centroid: 80% pass, 49 fps
3. Moving-blob filter: 87% pass (daytime), 49 fps

Temporal alignment 100% throughout all three trackers.

### Negative Results (Published)
- FD-001: Higher frame rate decreased accuracy (10fps < 6.7fps)
- DL-001: Pitch passes more than yaw in EE-003

### Key Parameters (v0.3)
- JERK_MIN_THRESHOLD: 0.15 m/s³
- MAD multiplier: 2×
- MATCH_WINDOW_MS: ±500ms
- Refractory period: 150ms
- CAMERA_PIPELINE_LATENCY_MS: 80ms
- CFC-005 INVERSION_THRESHOLD_MS: 250ms
