| Exact MCU/package and CubeMX configuration | Peripheral and pin bindings; no assignments made yet |
| STOP and latch signals, polarity, and independent shutdown circuit | Board input normalization and hardware shutdown verification |
| Master enable and contact/output feedback availability | Driver sequencing and detection of failed power removal |
| Rail enable polarity, power-up defaults, and permitted combinations | Real output mapping and configuration validation |
| Voltage/current limits, ADC range, scaling, calibration | Overvoltage/overcurrent input production and measurement validity |
| Relay topology and settling/break-before-make requirements | Routing validation and safe transitions |
| Adapter identity and safe stimulus limits | Profile/adapter compatibility checks |
| Maximum fault-response time and watchdog/reset behavior | Safety service deadline and independent supervision |
| External-energy permission and contact-safe shutdown ordering | Do not equate local output OFF with a safe Kelvin relay transition |
| Independent passive phase sensing versus switched Kelvin paths | Back-EMF observation without hot-switching measurement contacts |
| CubeMX/CubeIDE and HAL versus LL choice, and how generated code is integrated | Board-binding layer structure and build integration |
| LM317 current-source control, ranges and measurement feedback | Kelvin excitation control and actual-current validation |
| CAN transceiver enable/standby and termination control | CAN driver power states and termination capability flag |
| RS-485 DE/RE behavior, termination and biasing | Direction switching timing and bus configuration capability |
| UART voltage levels and level translation | Selectable 3.3 V/5 V serial capability, not bare MCU pins |
| USB-C role, power and data architecture, including isolation | USB stack, descriptors and power negotiation behavior |
| Back-EMF front-end scaling, clamp behavior and safe maximum | Passive EMF measurement range and over-range handling |
| DUT measurement rating: batteries up to 96 V, inputs rated 120 V DC for headroom (owner, 2026-09-24). A full 96 V-class pack reaches about 109-110 V, so confirm the ~10 V transient margin. Still open: the measurement-category confirmation, and a review of the Rev 0.9 handoff (sized for 84 V-class packs) against it: dividers, clamps, isolation, relay contacts, connectors, clearances | Over-range limits and UI warnings come from the reviewed design via the board definition; 120 V is a rating, not an ADC full scale or trip threshold |
| Nonvolatile memory for calibration, manufacturing data and logs | Record store transport, sizing and wear strategy |
| Meaning of master current relay versus generic output permission | Separate physical Kelvin master from 5 V/12 V sensor rail controls |
