What's Changed

Mini Diarium 0.6.2 brings two new locking controls: auto-lock when the window loses focus so you can minimize or switch away without leaving your journal open, and a per-entry lock that makes individual entries read-only so you can browse without worrying about accidental edits. The auto-lock timeout now enforces a 5-second minimum to keep the app usable.

Added

• Lock journal when the window loses focus (TODO-0068, addressing #194 (https://github.com/fjrevoredo/mini-diarium/issues/194)): a new "Lock when the window loses focus" toggle in Preferences → Security (off by default, independent of the existing idle-timer auto-lock) locks the journal a few seconds after the app window loses OS-level focus — minimizing, Alt+Tab/Cmd+Tab away, clicking another window, or Cmd+H on macOS. A short debounce means a quick misclick outside the window doesn't lock the journal if focus returns in time, and opening one of the app's own native dialogs (export, import, key-file save) never triggers it. Detection lives in Rust (WindowEvent::Focused) rather than the DOM visibilitychange API, which does not reliably fire on window minimize in the bundled WebView2. Verified end-to-end on Windows; macOS/Linux rely on the same cross-platform windowing API and have not been separately live-tested.
• Per-entry lock against accidental edits (TODO-0071, addressing #205 (https://github.com/fjrevoredo/mini-diarium/issues/205)): a lock/unlock button in the editor's entry nav bar makes an entry read-only so you can reread older days from the calendar or timeline without risking a stray edit. A locked entry cannot be edited, deleted, or re-tagged — the editor, title field, formatting toolbar, delete button, and the add/remove-tag controls all disable, and the backend rejects saveentry, deleteentry, addtagtoentry, and removetagfromentry for a locked entry as a safety net. Locked days show a small passive lock indicator on their calendar cell and timeline row (the toggle itself lives only in the editor). This is a convenience affordance, not a security feature: the lock state is stored as a plaintext column and is independent of the journal's auth-lock. Requires a database migration (schema v12 → v13) that runs automatically on first unlock.

Fixed

• Auto-lock timeout floor (TODO-0069): the auto-lock timeout preference can no longer be set below 5 seconds. Any pre-existing stored value outside the 5–999 range is corrected automatically on next load. Addresses #194 (https://github.com/fjrevoredo/mini-diarium/issues/194).
