The fixed 2s delay was insufficient — Arti's native layer releases
file locks asynchronously. Now stop() waits for the actual
"state changed to Stopped" log confirmation via CompletableDeferred,
with a 10s timeout as safety net. This ensures the file lock is
truly released before start() creates a new ArtiProxy instance.

EXTERNAL means another Tor process (e.g., Orbot) is running on the
device. No reason to keep our internal Arti alive alongside it.
Also removed the fallback that started Arti when the external port
was invalid — if the user chose EXTERNAL with a bad port, Tor should
be off, not silently falling back to internal.

Users in restrictive countries need Tor circuits torn down when they
switch to OFF — an idle proxy still maintains detectable connections.
stop() is now called only on explicit OFF toggle (user action), not on
flow pause/resume (app lifecycle). This avoids file lock races on
resume while ensuring OFF truly disconnects from the Tor network.

ArtiProxy holds an exclusive filesystem lock. Destroying it on OFF and
recreating on INTERNAL caused lock conflicts because the native layer
needs time to release the lock.
Instead, create ArtiProxy once and never destroy it. When Tor is OFF
or EXTERNAL, the proxy sits idle with no SOCKS connections — negligible
resource usage. This eliminates all file lock race conditions.
Also wrap start/stop in NonCancellable to prevent transformLatest
cancellation from leaking half-initialized proxy instances.

The callbackFlow-based TorService created a new ArtiProxy on every flow
collection. When the app paused and resumed, the old instance's file lock
wasn't released before the new one started, causing "Another process has
the lock on our state files" errors.
Redesigned TorService to own a single ArtiProxy with explicit start/stop:
- ArtiProxy is created once and reused across flow re-collections
- State exposed via MutableStateFlow instead of callbackFlow
- Mutex guards start/stop to prevent races
- TorManager calls service.start() and service.stop() explicitly when
switching between INTERNAL/OFF/EXTERNAL modes
- stop() includes a 2s settle delay for native file lock release

Address gaps found in code review:
- Use AtomicBoolean/AtomicLong for state accessed from native Arti
log callback thread (was a data race)
- Add bootstrap timeout monitor (120s) that restarts Arti once if
bootstrapping stalls, following BitChat's inactivity pattern
- Clean up failed ArtiProxy instances before port retry
- Detect "Another process has the lock" fatal error from Arti logs

Replace Guardian Project's tor-android (C Tor) and jtorctl with
arti-mobile-ex, a Rust-based Tor implementation. This eliminates
the Android Service binding complexity in favor of an in-process
ArtiProxy object.
Key changes:
- TorService: Replace ServiceConnection to org.torproject.jni.TorService
with direct ArtiProxy.Builder/start/stop API. Bootstrap state detected
via log parsing (following BitChat's pattern).
- TorServiceStatus: Remove TorControlConnection field (Arti doesn't
support jtorctl control protocol).
- RelayProxyClientConnector: Remove DORMANT/ACTIVE/NEWNYM control
signals. Arti manages its own circuit lifecycle internally.
- Dependencies: Replace tor-android + jtorctl with arti-mobile-ex 1.2.3.
TorManager's external API (status/activePortOrNull StateFlows) and all
downstream consumers (DualHttpClientManager, TorSettings, UI) are
unchanged.

Instead of replacing the new bookmark list, the migration now checks for
an existing kind 10003 event and merges old bookmarks into it, skipping
duplicates that already exist.
https://claude.ai/code/session_01U9sjQHQMVVHxYiesoXjqop
Rename the existing BookmarkListEvent (kind 30001) to OldBookmarkListEvent
and create a new BookmarkListEvent with kind 10003 as per the updated spec.
- OldBookmarkListEvent (kind 30001): Kept as-is for backward compatibility,
displayed as "Old Bookmarks" in the Bookmark Lists screen
- BookmarkListEvent (kind 10003): New replaceable event, all new bookmark
operations (save/check/remove) use this kind
- Both kinds are displayed as separate items in the Bookmark Lists screen
- Old Bookmarks screen includes a "Move All to New Bookmarks" button that
migrates public bookmarks to public and private to private
- Created PrivateReplaceableTagArrayEvent base class for replaceable events
with encrypted private tags (kind 10003 is in the 10000-19999 range)
- Updated all relay filters, search queries, and profile views to fetch
both kinds
- Updated Android and Desktop modules
https://claude.ai/code/session_01U9sjQHQMVVHxYiesoXjqop
Adds 6 preview functions covering:
- PictureCardCompose with title, without title, and multi-image
- PictureCardCaption with title, without title, and long content
- Uses ThemeComparisonColumn for light/dark theme comparison
- Uses mock PictureEvent JSON data consumed via LocalCache

Wrap all Tor library interactions in try-catch blocks so that failures
in the Tor service (JNI, control connection, bind/unbind) are logged
and gracefully degrade to TorServiceStatus.Off instead of crashing
the entire app.

The visual transformation for message edit fields now processes nostr:npub1...,
nostr:nprofile1..., and @nprofile1... mentions in addition to the existing @npub1...
pattern. Both UrlUserTagOutputTransformation (new API) and UrlUserTagTransformation
(old API) are updated to resolve these to user display names.
