Reliability.

Look closely at the boundaries where an ordinary workflow can become incomplete. This collection covers browser recording state, measurement gaps, logfile rotation and recovery, and the signals used during an investigation. The practical question is what the system records when work pauses, fails, restarts, or arrives late.

Select one failure path and read the resulting records before expanding instrumentation. The guides favor explicit partial states, bounded recovery behavior, and representative tests. A successful operation in one component does not automatically establish that every downstream reader received the same complete result.
