- Settings → Security lists every profile's stored credentials (kind and
whether it's in the keychain or the vault; the keychain is probed per
kind on a background thread since it can't be listed) with Forget.
- Change Master Password re-encrypts every vault entry under a fresh
salt and key with a new verifier, after checking the current password,
in one atomic write (Vault::change_password; tested that the old
password stops working and every value survives).
- Settings → Diagnostics shows version, platform, data/database/log
paths and sizes, keychain and vault state, counts, sync and launch
settings, with Copy Diagnostics; it never includes credentials.
Openable with --open settings:diagnostics.
