| # Hyperion Drive AV Safety Intelligence Pack — Schema |
|
|
| One row = one complete driving event chain. All records share the same seven top-level fields. |
|
|
| Schema version: `1.0.0-hyperion-drive-sample` |
|
|
| ## Top-level fields |
|
|
| ### `schema_version` — string |
| Schema identifier. Constant within a sample release. |

| |---|---|---| |
| | `failure_class` | string | `Sensor_Fusion_Conflict`, `Mechanical_Latency_Failure`, `Perception_Hallucination`. | |
| | `causal_chain` | list<string> | Ordered event labels (e.g., `ICE_DETECTED`, `TRACTION_CONTROL_ENGAGED`, `BRAKE_FLUID_PRESSURE_LAG`, `ABS_PUMP_STALL`). Each label appears as the `event_name` of one `can_bus_telemetry` entry. | |
| | `reaction_time_ms` | int | End-to-end reaction time (ms). | |
| | `tracked_signals` | list<string> | Which signal fields drive this failure (e.g., `wheel_speed_kph`, `brake_pressure_bar`). | |
|
|
| ### `can_bus_telemetry` — list<struct> |
| Ordered CAN / Ethernet bus messages observed during the chain. |
|
|
| Message struct: |
|
|
| | Field | Type | Notes | |
| |---|---|---| |
| | `timestamp` | string (ISO-8601) | Message timestamp. | |
| | `vin` | string | Synthetic VIN (`SYN-VIN-*`). Matches `vehicle_context.vin`. | |

| | `signals.radar_distance_m` | double | Closest radar return, meters. | |
| | `signals.brake_pressure_bar` | double | Brake line pressure (bar). | |
| | `signals.traction_slip_pct` | double | Traction slip percentage. | |
|
|
| ### `detection_logic` — struct |
| Anomaly-signature metadata describing why this chain is flagged. |
| |
| | Field | Type | Notes | |
| |---|---|---| |
| | `signature` | string | Human-readable signature (e.g., `Safety Violation: Mechanical_Latency_Failure detected`). | |
| | `anomaly_score` | double | 0–1. Higher = more anomalous. | |
| | `baseline_deviation` | string | Short English description of the deviation. | |
|
|
| ### `simulation` — struct |
| Simulation engine provenance. |
|
|
| | Field | Type | Notes | |
| |---|---|---| |
| | `synthetic` | bool | Always `true`. | |
| | `engine` | string | Simulation engine label (`hyperion_physics_sim_v1`). | |
| | `chaos_profile` | string | `Black_Ice`, `Blinding_Glare`, `Intermittent_CAN_Bus_Error`, `Sensor_Ghosting`. | |
|
|
| ## Distribution of this sample |
|
|
| - 10,000 event chains total. |
| - Safety criticality: balanced (~2,500 per class). |
| - Failure class: balanced across 3 classes (~3,300 each). |
| - Vehicle model: balanced across 3 models (~3,300 each). |
| - Drive mode: balanced across 3 modes (~3,300 each). |
| - Chaos profile: balanced across 4 profiles (~2,500 each). |
|
|
| ## Sanitization notes |
|
|
| - Internal identifier prefix (`SIMA-V4-AUTO-*`) has been normalized to `HYPERION-*`. |
| - Internal physics engine code name (`Hyperion-Physics-V2`) has been normalized to `hyperion_physics_sim_v1`. |
| - VIN values have been replaced with a `SYN-VIN-*` prefix so they cannot be confused with real WMIs assigned to specific manufacturers. |
| - Vehicle model names are abstract placeholders (`EV_Sedan_Alpha`, `Autonomous_Shuttle_V2`, `Heavy_Duty_Truck`), not real product names. |
| - No real vehicle logs, real VINs, real user data, or identifiable information are present. |
|
|
| ## Relationship to the full pack |
|
|
| The production pack scales to 1M+ event chains with finer-grained signal sampling (ms-level CAN traces), expanded scenario coverage (rain, snow, construction zones, V2X signal loss, bus cyberattacks), additional vehicle classes (motorcycle, delivery robot, transit bus), per-sensor noise models, and ROS-bag / CAN DBC-aligned delivery. See the pack card for commercial access. |
