Each emitted `TelemetrySample` explicitly stamps: + - `gpsTimestamp`: Exact time of the satellite fix. + - `gpsAgeMs`: Calculated difference `(now - gpsTimestamp).inMilliseconds`. + - `imuTimestamp`: Exact time of the latest IMU event. +- **Freshness Discounting:** When moving at $>3\text{ MPH}$, if `gpsAgeMs > 2000\text{ms}`, the sample is immediately downgraded to `suspect` with a penalty applied to GPS confidence. + +--- + +## Section B: Threat Matrix & Forensic Countermeasure Assessment + +| Failure Mode | Forensic Mechanism | Severity | Hardened Countermeasure | Verification Test Status | +| :--- | :--- | :--- | :--- | :--- | +| **Stoplight GPS Drift** | Satellite multipath jitter causes pseudo-movement at rest ($0.3\text{–}1.2\text{ MPH}$). | High | **Stationary Distance Gate:** `RideStateMachine._processStats` halts distance accumulation unless `speed >= 1.0 MPH` and `gpsAccuracy <= 35m`. | **PASS** (`forensic_speed_lean_gforce_test.dart`) | +| **GPS Multipath Speed Spike** | Sudden coordinate jump produces momentary $300+\text{ MPH}$ velocity. | Critical | **Distance-Time Jump Rejection:** `LocationService._isValidPosition` rejects fixes with derived velocity $>100\text{ m/s}$ ($>223\text{ MPH}$) and distance $>50\text{m}$. `TelemetryValidator` verifies coordinate delta $\le 110\text{ m/s}$. | **PASS** (`phase9_forensic_validation_test.dart`) | +| **False Lean from Braking/Accel** | Dynamic acceleration creates pseudo-roll when motorcycle brakes or accelerates hard. | High | **Dynamic Gyro Lock:** `SensorFusionService` checks dynamic $G = |\sqrt{a_x^2+a_y^2+a_z^2} - 1.0\text{g}|$. When dynamic $G > 0.08\text{g}$, $\alpha$ transitions dynamically to $0.998$, locking lean angle calculation to the gyroscope. | **PASS** (`sensor_fusion_physics_test.dart`) | +| **False 1.0g Linear G-Force** | Earth's $1.0\text{g}$ gravity vector measured as linear acceleration when bike is upright. | Critical | **Gravity-Decoupled Linear Stream:** Utilizes `userAccelerometerEventStream` which strips Earth gravity ($0.0\text{g}$ at rest).

Complementary Filter Stability Under Acceleration +The motorcycle roll angle $\theta_t$ is updated at time step $\Delta t$: +$$\theta_t = \alpha \cdot (\theta_{t-1} + \omega_{roll} \cdot \Delta t) + (1 - \alpha) \cdot \theta_{accel}$$ +Where: +$$\theta_{accel} = \arctan2(a_y, \sqrt{a_x^2 + a_z^2})$$ +Under hard acceleration ($a_x = 0.8\text{g}$), $\theta_{accel}$ is corrupted. The dynamic filter triggers: +$$\Delta g = \left| \sqrt{a_x^2 + a_y^2 + a_z^2} - 1.0 \right| = 0.28\text{g} > 0.08\text{g} \implies \alpha = 0.998$$ +At $50\text{ Hz}$ ($\Delta t = 0.02\text{s}$), accelerometer influence is restricted to $0.2\%$, preventing pitch-induced lean distortion. + +### 2. Haversine Distance & Velocity Gating +For two successive GPS fixes $P_1(\phi_1, \lambda_1, t_1)$ and $P_2(\phi_2, \lambda_2, t_2)$: +$$d = 2R \arcsin \left( \sqrt{\sin^2\left(\frac{\Delta\phi}{2}\right) + \cos\phi_1 \cos\phi_2 \sin^2\left(\frac{\Delta\lambda}{2}\right)} \right)$$ +$$v_{derived} = \frac{d}{t_2 - t_1}$$ +If $v_{derived} > 100.0\text{ m/s}$ ($223.7\text{ MPH}$) and $d > 50.0\text{ m}$, $P_2$ is immediately classified as a teleportation artifact and discarded. + +### 3.

Mount Android device securely using a vibration-damped handlebar/stem mount. +2. Complete phone calibration before departure via the MotorSignal In-App Calibration wizard. +3.
