ADDED Requirements

Requirement: Lab brick

Bring-up SHALL use the NVIDIA Jetson AGX Thor Developer Kit (T5000 module).

Scenario: first power-on

• GIVEN no custom carrier yet
• WHEN the lab kit is used
• THEN I/O is the kit’s 5GbE, QSFP28 (independent MGBE lanes), USB-C, and HSB/USB cameras

Requirement: Production ceiling

Production body design SHALL fit the T4000 SOM: 87 × 100 × 15.29 mm, 699-pin B2B, default 70 W, throttle at 90 W TMP, 1× NVENC, 3× 25GbE, no CAN. The carrier SHALL supply SYS_VIN_HV 7–20 V and SYS_VIN_MV 5 V. It SHALL NOT require T4000 SYS_VIN_SV (T5000-only). T4000 is the default production module. T5000 is permitted only when the required satellite encode load cannot remain camera-side or otherwise exceeds the validated T4000 hybrid budget.

Scenario: drop to T4000

• GIVEN hybrid HEVC satellites
• WHEN the body is a T4000 SOM
• THEN Thor encodes the body camera only and satellites remain camera-side H.265

Scenario: rails

• GIVEN a production carrier for T4000
• WHEN the SOM is seated
• THEN HV 7–20 V and MV 5 V are present and SYS_VIN_SV is absent

Scenario: T5000 escape

• GIVEN satellite count or encode demand that will not stay camera-side within the T4000 hybrid budget (1× NVENC, HQ 2× 4Kp30)
• WHEN the body module is chosen
• THEN T5000 may be used; otherwise the body stays T4000
