outsideWorktreeOptions() now returns undefined for an adopted session as it does for a remote or Docker one: session.remote and session.docker are undefined on an adopted session, so it needs its own test. An adopted pane gets no paneCwd today (paneExitApplies), so nothing changes in practice; the rule stays true if that ever changes.
The live-worktree.ts @fileoverview said the routes re-check only the realpath of an outside worktree. They also judge the attachment guard rules again on every request (isOutsideWorktreeRootRefused() through withGuardedOutsideWorktree()), which is what makes a confinement or blocked-tree change apply at once.

Keep the 1.49.0 API meaning: liveWorktree and root=live stay inside the
session folder, and an outside worktree is published as outsideWorktree
and walked only with root=live-any.
Refuse a symlinked .git folder as the main worktree, sensitive files
inside a followed worktree, and any outside worktree while attachment
confinement is on or around a blocked tree. The file routes re-check
the guard settings on every request, and a throwing rule check refuses.
The panel keeps its Back to worktree button while pinned to the session
folder.

#772 made the Files panel follow an agent into a worktree inside the
session's folder. A worktree beside the repository (git worktree add
../feature, or an EnterWorktree into one that already exists there)
stayed unfollowed, since serving it needs a second confinement root.
findOutsideWorktree() answers that case without running git. The
nearest .git above the pane must name <common dir>/worktrees/<id> of the
session's own repository, and that registry entry must name the
candidate back (or the .git folder must be the common dir itself). It
refuses /, the home folder and above, any folder holding workingDir and
Docker case workspaces, and multi-user mode applies the owner's
folderAllowedForUser rule. The answer is liveWorktree with outside: true
and the folder's real path.
The file routes serve an absolute path inside that worktree, and only
while the folder still resolves to the recorded path. A relative path
still resolves against workingDir alone. The browser routes such paths
to the editable preview, and root-relative markdown refs resolve from
the top of the worktree.

classifyDotGit() checked with lstat and then opened by name, so a FIFO
swapped in between the two blocked a threadpool worker. The open itself
now refuses both, and the handle is judged.
Reported on #772.

The lookup judges liveWorktree.path lexically and only when the pane moves,
while the route's probe and readdir both follow symlinks. A symlink put at
that path, or at a parent of it, without moving the pane re-rooted the listing
outside workingDir. Names and sizes leaked, while file-content and file-raw
still refused the paths.
The route now resolves both folders on every request and walks the worktree
only when it lies strictly inside the resolved workingDir, otherwise it walks
workingDir. Only the check uses the resolved paths: the walk keeps the session's
spelling, so a workspace reached through a symlink still gets paths relative
to workingDir.

Claude Code's EnterWorktree moves the running process into
<repo>/.claude/worktrees/<name>, while Session.workingDir stays on the main
checkout. The Files panel kept walking workingDir, so it listed a tree the
agent had left.
paneCwd already follows the move, measured on Claude Code 2.1.318 in both
directions, so nothing new has to track the agent. It also follows every cd
in a shell, so a new SessionState.liveWorktree narrows it to a linked
worktree, read from the .git file without starting git.
Only a folder strictly below workingDir is ever an answer, and the listing
only starts there: returned paths stay relative to workingDir, so the
preview, raw and edit routes are unchanged and confinement does not widen.
A worktree outside the session folder stays unfollowed.
The panel asks with root=live, shows a strip naming the worktree with a
switch to the session folder, and follows the agent in and out while open.
