`cwd` beside the fixed `workingDir` reads ambiguously on a public API surface, and
`paneCwd` says where the value comes from, like `paneExit`. Also pin the field on
the payload the browser really receives (getSessionStateWithRespawn), and give the
pane-directory text its own architecture-invariants paragraph.

tmux reads a pane's directory from the process cwd, which is always the
resolved path, while workingDir keeps the spelling the case was created
with. For a workspace reached through a symlink every reading looked
like it was outside the workspace, so the browser sent each relative
link through the attachment route instead of the workspace routes.
Each session now resolves workingDir once in the background, bounded by
probePathKind() and a timed realpath(), and setCwd() writes a reading at
or under the resolved path back in workingDir's spelling. Until that
settles only a reading lexically inside workingDir is taken. An unknown
probe or a failed realpath leaves readings untranslated and retries
after WORKSPACE_REALPATH_RETRY_MS.
Also corrects two comments: cwd is written to state.json but never read
back, and a blank pane path is usually a pane whose program exited.
applyPaneExits() only applied the manager's directory when it returned a
value, so after a successful read a session that was split into several
panes, or was no longer on the socket, kept its stale cwd. The manager
already keeps its map across a failed or empty read, so the server now
applies its answer as given, undefined included, and setCwd() broadcasts
the clear once.
A blank #{pane_current_path} on a single-pane session (tmux could not read
the process cwd that tick) now carries the previous entry forward in
derivePaneCurrentPaths(), so only a split or unlisted session clears.
The server tests now drive the real TmuxManager with only the tmux read
faked. docs/api-reference.md documents SessionState.cwd.
A relative path printed in the terminal was resolved against the session's
workingDir, which is fixed at create time and never follows a cd. In a shell
that moved into a subdirectory or a sibling repo, the link opened the wrong
file or reported "File not found".
The pane-exit watcher's batched list-panes read already carries
#{pane_current_path}. derivePaneCurrentPaths() turns those rows into one
directory per single-pane session, TmuxManager.getPaneCurrentPath() serves it
from memory, and the server applies it on the existing paneExitsUpdated tick
as SessionState.cwd, broadcasting only on a change. No new tmux call, no new
SSE event. A failed read keeps the previous answers.
Session.setCwd() uses the paneExit scoping rule: remote and Docker sessions
never get a cwd (their local pane runs the ssh or docker exec client), nor do
direct-PTY or rediscovered sessions. The value is runtime-only.
In the browser, relativeResolutionBase() picks the live cwd when known and
workingDir otherwise. It only changes the base a relative path joins: the
result is routed as before, so a target outside the workspace still goes
through the attachment routes, and file-content/file-raw are unchanged.
