What it sent and what came back (the newest 1 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

At the start of the two-factor login wizard, mints a one-time nonce that ties the challenge to this session.

What our machine does with it

Fires on its own as the two-step page arms; log-cli does not read it and instead waits for the code field or the method picker.

What can go wrong

A failure here would break the 2FA wizard before the code box appears; otherwise it is background to our flow.
