- §4: the exact boundary — enclave models protect inference, stored
history is operator-readable; recommend Temporary Chat + enclave model
for sensitive material. New subsection on Temporary Chat (per-
conversation toggle, Default Temporary Chat setting, trade-offs,
what it does and does not change).
- §8: temporary chats are never retained.
- getting-started: add Temporary Chat to the chat feature list with
the Settings → Conversations default toggle.
No engineering change; documents what the deployed chat (1.4.5) already
supports. Member request 2026-10-28.
