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.

"R0lGODlhAQABAAAAACwAAAAAAQABAAACAkwBADs="What it does
Slack's client sends the same batched usage events to the workspace host, workspace.slack.com/clog/track: each body is a logs JSON list (one shown carries an experiment_name event) and each answer is the 1x1 GIF with status 200. Seen 15 times in one run, on step 5 saveState, step 7 pageText, steps 9 and 16 press Control+a, step 14 press Enter and step 20 snapshot (272-1344 ms).
What our machine does with it
Nothing: no log-cli code calls it, and rea found no script that sends it (its Called from is empty). It is Slack's client telemetry seen in the inspect run only.
What can go wrong
All 15 calls were 200. A failure would not affect a run; no answer of it is read by us.
