From 8da67ef923defaf2b59f3b7f6ef80b6e29e9d939 Mon Sep 17 00:00:00 2001 From: Leo Li Date: Tue, 27 Oct 2026 23:41:12 -0700 Subject: [PATCH 01/33] cmux NEXT Cloud: pick a chat's machine from its folder (repo, ref, size, task kind), sent as autosize A chat sent to Cloud no longer needs a machine or size choice: CloudWorkPick reads the chat's folder (repo key and GitHub repo from the remote, branch and whether it is pushed, git object size, root files, task kind, .cmux/machine.toml, Codex broker) and Move to Cloud with no machine to reuse, and New Cloud Machine from a chat, send its autosize with POST /api/vm. The answer's sizePick stays on the machine's session for the hand-off. Behind Labs preview features.

A page script could name any folder on this Mac. The hand-off now takes the folder's canonical path (realpath, off the main actor) only when it is inside one of the pane's roots by components, the same roots AcpmuxPathPolicy uses for a chat that starts here: the pane's own and the New Tab scan's, never home or above it, plus the folders the person added. Anything else is refused with transport.path_outside_roots before the hold and the gesture. No folder from the page still means the tab's own folder, which the host reads. - Every Cloud start from the same folder synced into the same folder on a reused machine, and Move to Cloud's sync overwrites every file the machine changed, so a second Cloud chat could write over the first one's work. A start now copies into its own place under the work root (chats/). A retry of the same send lands in the same copy. Tests: a folder outside the roots, a link out of a root, a `..` path out of it, a missing folder, the disk's root, home, and a folder under home when the pane's folder is home are all refused and never reach the runner. The root's own folder still starts with its canonical path, and a send's place is its own and stable for a retry.

A retry that fails the same way is shown as before. Decisions are logged (first_send_retry, auto_resume_skipped). - daemon/cloud_handoff.rs: such a turn is not reported failed before its retry is decided.

The pane now checks that upload root against its roots too (AgentPaneHandOff), hands it on as AgentPaneCloudStart.uploadRoot, and the App copies only that folder (CloudStartChat.uploads): a grant of /repo/paint never uploads /repo. - [P1] Destinations records, per send key and machine, that the send's copy finished. A retry whose copy finished opens its chat by its tab key without pushing again, which would overwrite what the chat already changed there. - [P2] A new machine for a send is created under AgentPaneCloudStart.createKey (from the send key), so a retry after a lost create answer gets the same machine, never a second VM.
