The security wording claimed a folder strictly below workingDir was the whole
argument, which the symlink fix showed was only the lookup's half. The rest is
docs that were missing: liveWorktree, root=live and worktree in the API
reference, the mechanism section the CLAUDE.md paragraph had no pointer to, what
a root=live query matches against, and the limits a reader meets in the wiki
(the Git panel stays on the session's folder, a session started below the
repository's top is not followed, a page under .claude/worktrees opens as
source).

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.

The Docker rule was applied to the CASE folder and its common git dir
only. A Docker case can be linked to any host folder, including a managed
worktree (`<repo>/.claude/worktrees/<name>`), which is a natural setup for
running one of the parallel agents in a container. Removing that worktree
from the local case's dialog, or through Close Session's "Kill & remove
worktree", ran `git worktree remove`, which runs a git status INSIDE the
tree (container-written files, checkout filters on this machine) and then
deletes the whole tree, ignored files included, while the container still
mounts it. Reproduced on an isolated instance: DELETE answered 200 and the
Docker case's workspace was gone.
That contradicts the invariant the PR itself documents in CLAUDE.md ("git
never runs ... at or inside a Docker workspace"). removeCaseWorktree now
refuses (400) a present worktree that is, sits inside, or holds a Docker
case workspace, before any git runs; the DELETE route passes the Docker
roots it already reads for the case check. A worktree whose folder is gone
is unaffected (git only drops its record there). Unit and route tests
cover both directions and an unrelated Docker workspace; docs updated.

With Codeman Agent Skill on (agentSkillEnabled), every session create
writes the skill into the folder the session runs in, so a session in a
worktree leaves an untracked .claude/skills/codeman/ (claude) or
.agents/skills/codeman/ (codex, gemini and the rest) behind. git then
refuses `git worktree remove` for that worktree forever, and an agent
running `git add -A` there would commit Codeman's skill into its branch
(reproduced: the worktree's status showed "?? .agents/" and
"?? .claude/").
A create now excludes <skills dir>/codeman/ next to the hooks file, for
every skills folder the registry names (capabilities.agentSkillDir,
read at call time by the route and passed in as data, so no CLI id is
branched on). Like the other lines it is only added when git does not
already ignore the path, and only to the repository's local
info/exclude.

When a managed worktree's folder is deleted by hand (a user in a file
manager, an agent's rm -rf), git keeps its record and lists it as
prunable. Codeman then had no way out: the dialog showed the row as
"missing" with no action, DELETE answered "No worktree named ...", and
the name could never be used again (the branch still existed, and with
another branch git refused "a missing but already registered
worktree"). Reproduced on git 2.43; git's own `git worktree remove` on
the missing path drops the record with exit 0.
Removal (only removal, never a session start) now accepts a worktree
whose folder is gone when git lists it at exactly the managed path, as
prunable or locked, and no component on the way is a symlink or a file.
The live-session and lock refusals still apply. The dialog offers
Remove... (not Open) on such a row, with a note saying what it does.

Documents the worktree endpoints and quick-start's worktree field in
docs/api-reference.md, adds a Git Worktrees page to the wiki (sidebar,
Home index, a pointer from Core Concepts where sessions sharing one
case folder is explained), and records the rules that keep the feature
safe in docs/architecture-invariants.md with a short CLAUDE.md pointer:
only the managed .claude/worktrees path is ever touched, git never runs
over a Docker workspace, removal is never forced and branch delete is
-d only, and sessions start through the existing create paths.
