| Area | Stimulus | Required evidence | Expected result |
|---|---|---|---|
| Boot | Flash/start both boards | `boot`, `role`, periodic `health` from each | Exactly one sender and receiver; no reset loop; bounded heap/stack |
| Time | Sender receive window and receiver time-sync | sender request/completion, receiver transmit | Valid UTC completion; misses remain visible |
| Time | Sender receive window and receiver startup time-sync burst | sender request/completion, receiver startup transmit | Valid UTC completion during the 180 s baseline; misses remain visible |
| Meter baseline | Real optical meter | `meter_frame`, `meter_sample` | Frame classification and seconds index when present; no secrets/values logged |
| Batch | Normal 30 s batching | create, encode, every TX/RX chunk, complete, decode, ACK TX/RX | One batch ID correlates end to end |
| Meter timeout | Partial start then >1.5 s pause | `classification=timeout`, health | No reset; next valid fixture recovers |
