REQ-FW-005 — Passive Temperature Emulation (4 channels, no firmware role)

The tester shall present a hardware-strapped forward voltage on each of 4 remote-diode temperature channels (DXP/DXN, J9–J12) for the DUT's temperature sensor. This is passive hardware — no MCU pin is connected, so the firmware has no temperature function. See [[E-006]].

Each of the 4 channels presents the documented Vf (≈0.6 V @ 25 °C class, set by the populated BAT54 ladder); the DUT reads the corresponding temperature within range. Verification is station/DUT-side; the fixture firmware is not involved.
