Turn a recording into evidence.
Cycle mode expects one timestamped row per event or message. It measures adjacent intervals; missed cycles are estimates from the expected period. Response mode pairs each rising request edge with the first rising response at or after it and before the next request. The first sample sets the initial state; it is not an edge. A recording that ends before a pending deadline is marked INCOMPLETE. Delays are measured at the recorded sampling resolution.
cycle deviation = observed interval − expected period
response delay = response-edge time − request-edge time
All reported times are milliseconds relative to the first timestamp.
