What it sent and what came back (the newest 3 from our runs)
Read from each run's own recording (rule 73), secrets and signed link tokens taken out. Kept in ~/.logCli/rea/clientFacts.json, so it stays after the run is pruned.

}What it does
Logs client timing data (app_id, start_time, end_time) in the background on most pages; it answers an empty payload.
What our machine does with it
Nothing. The flow generator never takes it as a step's confirmation (NOT_CONFIRMING matches Logger in flowFromRecording), and no step waits on it.
What can go wrong
Harmless.
