Only a fingerprint of it (a one-way hash). The key itself is not on this server. If it is lost it cannot be looked up — it gets replaced.
Time, which endpoint, which topic, how long it took, and which account. Not the content of

the portal, and /receipt in ChatGPT.
Verdicts on briefing cards, lesson answers and evidence paths, ticks on tasks, and decisions on requests go into Clara's own files — the same files the Telegram channel writes to. There is one record, not two.
It talks to one place only: Clara. It has no path to passwords, keys, or the mail of anybody else, and it cannot send anything to other people.
When a question needs more than a lookup, Clara thinks it through on the house subscription seat. The question and the fact sheet go to that model for that one answer; nothing is used for training and nothing is kept there.
