Message contents, +names, titles, ids and cursors are sealed and lookups use HMAC tags; timestamps, sources and the +settings file (never-remember lists included) are not encrypted. A search never widens past the +conversation the focused window names, except to conversations with exactly the same people; an +unknown or ambiguous title returns nothing rather than a guess. Mail gets no conversation scope: a +subject does not say who a mail is for, and the body (the quoted original's header included) is +shaped by the other person, so no audience read from it can be trusted; the engine never resolves +a title in a mail source either. Mail scope waits for the compose window's own To/Cc fields, read +through Accessibility. Groups (Teams, +WhatsApp) carry a per-group marker, so they never have exactly the people of a 1:1 chat or of +another group, and titles match whole, never in part. Mail threads are joined by headers a sender +controls, so each audience within a thread is its own conversation (`MailAudience`), mail people are +addresses (never display names or Reply-To), and only Mail's Sent mailbox or Outlook's outgoing flag +makes a message the user's own. Under +`-cotabby-debug`, `llm-io.jsonl` records full prompts, memory lines included, as it does typing +history. Like typing history, memory is on-device +only: the retriever returns nothing for the endpoint engine, the request factory drops it, and the +router refuses a request that still carries it.

The sender of a message never chooses +the conversation an answer treats as its own: a quoted mail is data only (what is asked, by whom) +and never names a remembered conversation, so all of its answer's facts come from opted-in sources +(each marked as another conversation's) or busy/free times; a chat must be the one conversation +the window names; mail without its quote below the caret gets no answer; and anything ambiguous +gives no answer. Other conversations are opt-in per source and off by default; Calendar is never an answer +source (only busy and free times, read live). + +The question is written by someone else, so it is treated as untrusted text: a message that reads +as instructions to an assistant ("ignore previous instructions", "list all the facts") gets no +answer, remembered text that does never reaches the prompt, and Apple Intelligence reads the +question, every fact and every name and title quoted, clipped and labeled as data, and the draft +must hold up on its own.
