| name | Collision guard node design | |
| description | Detects obstacles in the forward travel corridor and publishes an asserted braking request. Two proposed input checks can request braking for detected input faults. Their effectiveness and an independent camera-and-lidar architecture remain open design work. | |

| name | Input plausibility check | |
| description | Proposed check of image dimensions, encoding, pixel-data consistency, and acquisition timestamps before obstacle evaluation. A detected invalid input requests braking rather than allowing an untrusted image to justify continued motion. | |

| comment | Accepted dimensions and encodings, timestamp age limits, and fault-response timing remain to be specified and validated. This check does not establish that every obstacle is visible or detectable. | |

| id | com.example.stig.components.collisionguardnode.design.collisionGuardNodeDesign.frameContinuity | |
| name | Frame continuity check | |
| description | Proposed comparison with previous frames and acquisition timestamps to detect a nonadvancing or inconsistent image sequence. Detected sequence faults request braking. Repeated pixels alone do not establish a frozen camera, and a positive obstacle detection requests braking without waiting for confirmation in later frames. | |

|
| comment | Temporal acceptance criteria, frozen-sequence detection limits, and fault-response timing remain to be specified and validated. Comparing one camera with its own history does not provide independent obstacle detection; the camera-and-lidar design gap remains open. | |
