The wrapper's workingDir is the neutral /tmp, and everything master grew since
1.33.2 that branches on session.remote or session.docker read that as a local
session working in /tmp, because an adopted session keeps its connection on
adopt.remote and adopt.docker.
So uploads wrote into /tmp and closing the tab recursively deleted the shared
folder; the Git panel, its fetch and the fetch scheduler ran git on whatever sat
there; the image watcher, Read My Mind and the Discord bridge used that folder;
last-response paired a transcript by it and could show another conversation's
answer as this one's; a magic link in a container's output registered a file
from this host's /tmp; and guarded input could type into a human's composer.
Each now refuses or answers unsupported, the browser hides the rows that cannot
work, and Session Options shows where the foreign pane was instead of /tmp.
The custom-model route refuses as well, since it restarts the CLI in the pane.
The local version probe is skipped: the local binary says nothing about a
process someone else started, possibly on another host.
Also moves the guard test to port 0, which test-ports-guard now requires.

The hourly sweep called lstatSync and realpathSync on every live session's working directory, so a linked case on a mount that stopped answering blocked the event loop 30 s after boot and then every hour; the old sweep was fully async. uploadDirs() now probes the workspace with probePathKind() first and skips an unknown path without touching it, then uses fs.promises for the lstat and realpath. The sweep keeps the probe's stall cap; cleanupSession(), acting on one path at the user's request, passes pastCap and removes the directories with fs.rm.
Refusing an upload dir that sits strictly inside the data dir protected nothing (it only ever holds uploads, and a link is already excluded by lstat) while the route kept writing there, so uploads under a workspace like the ~/.codeman/app that install.sh clones were never swept and never removed. Only the two cases that matter stay refused: the upload dir being the data dir, or containing it.
Also: the ignore file's take-back after a failed write no longer replaces the error that caused it with its own, and the shared-dir test's header no longer names the fixed port it stopped using.
A pasted image landed in <workspace>/.claude-images/, a name that belongs to another tool, in a folder nothing ignored, so it showed up in git status of every case that ever received a paste. Uploads now go to a flat <workspace>/.codeman-uploads/ that carries a .gitignore of `*` (written once, never over a file already there): in the workspace because that is the only path identical for a local agent and a container, flat because a nested .codeman/ is the data dir itself when the workspace is the home directory.
The directory names live in paste-image-gc.ts alone. The old folder receives nothing but stays readable for one release: the hourly sweep and the delete cleanup go through uploadDirs(), the image watcher's ignore filter reads the names. uploadDirs() lists only real directories, none that is, contains or sits inside the data dir, and nothing for a remote session, since both consumers delete. The route refuses a remote (SSH) session before touching disk: the file would land on this host under the remote path, where the agent cannot read it.
test/paste-image-dir-shared.test.ts binds port 0 and leaves the port guard's legacy list.
Decided in #553.
