Add cmux session move for Claude sessions - #14959
Conversation
`cmux session move <session-id> --to <ssh-destination|local>` moves a stopped Claude Code session between this Mac and an SSH host and resumes it there in a new workspace (#14854, v1). It refuses while a Claude process for the session runs on either side, carries the cwd's git checkout (snapshot commit at refs/agent-move/<id>, same branch when safe, modified, deleted and untracked non-ignored files, worktree added when only the repository exists; refuses a dirty or diverged destination), then the transcript, session directory, file history and project memory (merged both ways, newest wins). A destination home at a different path is mapped and re-slugged. The resume uses the recorded launcher and clears the old local surface's resume binding. The move logic lives in CMUXAgentLaunch behind a command-runner protocol; its tests run the real git and rsync steps against a loopback SSH host.

Suppress helper output for JSON session moves.
With --json, the caller sets jsonOutput: false for both helpers. The local helper prints OK <workspace-ref>. The SSH helper prints its fallback text through printV2Payload. The caller then prints the move JSON. This makes stdout invalid for JSON consumers.
Add an explicit silent-output mode and pass it from this caller. Do not pass jsonOutput: true, because that would emit an additional helper JSON payload.
Suggested fix

Do not ignore move-record write failures.
If the move record already exists and the new atomic write fails, save leaves the old record in place. The command then opens the destination workspace and reports success. A later move without --from reads that old record and can use the previous host instead of the last destination.
Propagate the save error before opening the workspace or printing success. Recovery must then provide --from explicitly.

A detached destination HEAD can lose commits without a refusal.
The divergence guard only checks refs/heads/$branch. A destination checkout can have a detached HEAD with commits that no branch holds. apply itself creates this state when the branch is checked out in another worktree. In that case the dirty check passes, because the working tree equals the HEAD tree. Then git update-ref --no-deref HEAD "$sha" or git symbolic-ref HEAD moves HEAD away from those commits. After that, only the reflog holds them.
Also refuse when the current HEAD is detached and is not an ancestor of $sha.
🛡️ Proposed guard
if [ -n "$branch" ] && git rev-parse -q --verify "refs/heads/$branch" >/dev/null && ! git merge-base --is-ancestor "refs/heads/$branch" "$sha"; then
echo AM_DIVERGED
exit 3
fi
+if ! git symbolic-ref -q HEAD >/dev/null && ! git merge-base --is-ancestor HEAD "$sha"; then
+ echo AM_DIVERGED
+ exit 3
+fiAgentMoveCodeSync.carry maps AM_DIVERGED to destinationBranchDiverged only when branch is non-nil. When branch is nil, it reports gitFailed(step: "apply"). Add a dedicated error case if this refusal needs its own message.

- Treat a destination path as a checkout only when it is the top of its own repository, so a folder inside another repository (for example a home directory tracked as a repo) is never rewritten. - Check the transcript prefix before touching the destination checkout. - Write the source snapshot to refs/agent-move/outgoing/<id> and promote it to refs/agent-move/<id> only after the destination applied it. - Map the physical home path of the host, which is what Claude records. - Send remote scripts to `sh -s` on stdin inside a brace group, so csh and tcsh login shells work and no command can read the script. - Copy the index with its mtime when computing working-tree trees: a fresh mtime hid same-size edits from git's racy-clean check. - On a host, resume the plain agent argv instead of a cmux-owned launcher that points at this Mac's cmux binary. - Drop --json: the workspace commands print their own result line.

Preserve newer sidecar and file-history data.
The move path reaches these copies after the transcript prefix check. The sidecar and file-history transfers currently omit --update, so an older source can overwrite newer destination data. Add updateOnly: true to these two copies only. Keep the transcript copy unchanged because --update could skip a valid source extension when the destination mtime is later.
Suggested fix
- try copy(from: source, sidecar, to: destination, destinationProjectDirectory + "/")
+ try copy(from: source, sidecar, to: destination, destinationProjectDirectory + "/", updateOnly: true)
...
- try copy(from: source, sourceHistory, to: destination, destinationClaude + history)
+ try copy(from: source, sourceHistory, to: destination, destinationClaude + history, updateOnly: true)📝 Committable suggestion

First cut of the move action from #14854:
cmux session move <session-id> --to <ssh-destination|local>moves a stopped Claude Code session between this Mac and an SSH host and resumes it there.cmux session move 0b7a1e7c-3f0a-4c6e-9d59-8a0d8f7c2b11 --to dev@my-host cmux session move 0b7a1e7c-3f0a-4c6e-9d59-8a0d8f7c2b11 --to localWhat a move does, in order:
~/.claude/sessions/<pid>.jsonnaming the session, or aclaude ... --resume <id>process). v1 asks the user to exit the agent at a turn boundary; it does not stop a running agent.refs/agent-move/<id>, sends it with git over SSH, then checks out HEAD on the destination (same branch when no other worktree holds it) with the working tree at the snapshot. Deletions and renames carry. A worktree is added when the repository exists on the destination but the path does not. Refuses when the destination checkout has changes that did not come from this session, or its branch has commits HEAD lacks. A non-git cwd moves no files and says so.--no-codeskips this step.<id>/session directory,~/.claude/file-history/<id>, and the projectmemory/directory, merged both ways withrsync -u(newest wins, nothing deleted). Refuses when the destination transcript is not a byte prefix of the source.$HOMEis the same directory as the local home (same path, or a bind mount at the local path, checked withtest -ef), nothing is rewritten. Otherwise the home prefix is mapped, the project is re-slugged, and the output says paths were rewritten.cmux sshworkspace (or a local workspace for--to local) whose initial command resumes the session through the same resume builder as surface restore, so the recorded launcher, external launcher and permission mode carry over; falls back toclaude --resume <id>. When the session leaves this Mac, the old surface's resume binding is cleared so it does not auto-resume a second writer.--fromdefaults to where the last move put the session (~/.cmuxterm/agent-moves/<id>.json), so--to localneeds no host.The move logic is in
CMUXAgentLaunch/AgentMovebehind a command-runner protocol. Its tests run the realgitandrsyncsteps against a loopback SSH host (a runner that maps the host onto a second local home): round trip there and back, same-home detection, live refusal, dirty and diverged destination, worktree add, newer and diverged transcripts, non-git cwd, missing destination cwd.Not in this PR (tracked in #14854): Codex sessions, the sidebar move action, quiescing a running agent via the Stop hook, the write lease and commit on first remote hook event, and host-to-host moves without going through this Mac.

Summary by cubic
Adds
cmux session move <session-id> --to <ssh-destination|local>, which moves a stopped Claude Code session between this Mac and an SSH host and resumes it there in a new workspace.The move refuses while a Claude process for the session runs on either side. It carries the cwd's git checkout as a snapshot commit on
refs/agent-move/outgoing/<id>, promoted torefs/agent-move/<id>only after the destination applies it (same branch when safe, worktree added when only the repository exists on the destination, refused when the destination checkout is dirty, diverged, or not the top of its own repository). Session data — the transcript, session directory, file history, and project memory — is merged both ways with newest wins, but only after the transcript prefix check passes and before the destination checkout is touched, so a refusal leaves the destination untouched. Home paths are rewritten (and the project re-slugged) when the destination home differs, using the physical home path. Remote scripts travel tosh -sover stdin, so csh and tcsh login shells work. On a host, resume runs the plain agent argv; on this Mac it uses the recorded launcher, and the old surface's resume binding is cleared when the session leaves.--fromdefaults to the last move location, so--to localneeds no host. Includes a CHANGELOG entry and CLI help updates, and drops--json.The move logic lives in
