fix(devices): refuse a repository's checkouts to a watching device (#2250) - #2304
Follows #2246 and #2252 (merged), which refused a watching device a pane's command rows, the paths under a pane's folder and a plugin run's output the same way: refused, not trimmed.
Change
A watch-only device was refused a directory listing, but GET /api/worktree/list?workspace_id=… gave it herdr's whole worktree inventory for that workspace's repository: every checkout's absolute path, branch and label, including checkouts not open in herdr. The issue suggested trimming the answer, because the sidebar reads it on every device for branch names. Per the owner's decision for #2246/#2252 (refuse instead of hiding), the route is now refused to a watching device, and the client stops asking.
Access check (server/index.ts): the watch refusal covers worktree/list on this PC, on its /api/machines/local/ alias and on another PC's /api/machines/<id>/ route, answering 403 read_only.
PC proxy (server/machine-api.ts): a read-only connection is never forwarded worktree/list with the PC's credential, just as pane/files, pane/commands, agent/commands, plugin/action and sessions/history are not.
Client:
useWorktreeBranches takes watching: while watching it asks nothing, and a read_only answer stops its 30 s poll instead of retrying it forever. Its cache is keyed on the PC and the role, so a device signed in to drive reads branches again, and a downgrade drops the branches it had learned.
The sidebar passes watching, skips its per-workspace "is this a repository" probe while watching, and hides New worktree / Open worktree (drive features whose dialog lists the checkouts), as it already hides Earlier sessions.
The command palette gets watching from App and mounts no branch readers while watching.
Visible tradeoff: a watching device no longer shows branch names in the sidebar or the palette.
A driving device, the owner's token and the connection server's bridge token keep the route on every path.

Tests
Each new test failed on the code before the fix and passes after it:
server/device-access.contract.test.ts: a watching device gets 403 read_only on the local, local-alias and remote paths. A driving device reaches the route (workspace_not_found locally and through the alias for an absent workspace, 503 for an unconnected PC). Before the fix the local and alias paths answered 404, not 403.
server/machine-proxy.test.ts: the proxy never asks a PC for worktree/list for a read-only connection, and passes a driving device the PC's answer.
src/lib/useWorktreeBranches.hook.test.ts (new): a driving device polls again after 30 s. After a read_only answer the hook asks once and never again (it asked again before the fix). While watching it asks nothing, and after a switch to drive it reads and polls again (this failed with the refusal kept per PC only).
bun run check fast passes.
Manual QA
An isolated Ovis server (mkdtemp state dir, port 0, the ovis-test herdr session) has a workspace on a repository with one linked checkout, secret-branch, not open in herdr. Each path was requested with curl -i:
This touches observe permissions and an HTTP contract, so it was reviewed adversarially before opening:
omo-native-code-reviewer: APPROVE (after one fix round). It probed ./, %2e, ../, \, %6cist, ;x, case, // and a trailing /, plus GET, HEAD and OPTIONS. It also checked the WS and relay surfaces and the check order (the refusal runs before the alias rewrite and the proxy). It found no way to the answer.
MEDIUM: the read_only refusal was kept per PC, so a device signed in to drive later never read branches again until reload. Fixed: the hook's cache is keyed on the role, and there is a test for watch → drive.
LOW: the palette sent one refused request per open on a watching device. Fixed: it mounts no branch readers while watching.
LOW: branches learned before a downgrade stayed shown. Fixed by the same role-keyed cache.
LOW: the sidebar gating has no component test. Left: it matches the existing Earlier sessions gate, and the hook carries the behaviour.
LOW (after the fix): a refusal that arrives, followed by a downgrade and an upgrade, all between two health polls, keeps the refusal until reload. Left: it needs two role changes inside one poll interval.
LOW (both reviewers, and CodeRabbit as Minor): the palette kept the branches it read while driving after a switch to watching. It stays mounted while closed, so they outlived closing it too. Fixed in a follow-up commit: while watching, its branches are empty and the cached inventories are cleared.
Codex Sol 6.1 fast xhigh:APPROVE (after one fix round, re-reviewed on the fix only). It ran 532 method/path combinations without finding a watch-device bypass, and confirmed the new server tests fail against the unfixed code.
MEDIUM: the same refusal-outlives-role-change bug. Fixed as above.
LOW: cached branches survive a downgrade. Fixed as above.
LOW (pre-existing credential precedence): a request carrying both a valid bridge bearer and a watch device cookie is treated as the watch device, so it is now refused this route. Left: the bridge proxy strips cookies, so real bridge traffic never carries one. Changing which credential wins is outside this fix.
No REMOTE_BUNDLE_VERSION change: only a release PR raises it.
…2250)
A watch-only device could list every checkout of a workspace's repository (paths and
branches, those not open in herdr too) through /api/worktree/list on this PC, its local alias
and another PC's proxy route. It is now refused with 403 read_only, as a folder listing is, and
the proxy never forwards it for a read-only connection.
The client stops asking: useWorktreeBranches asks nothing while watching and stops its poll on a
read_only answer, its cache keyed on the role so a device signed in to drive reads branches
again. The sidebar skips its repository probe and hides New/Open worktree while watching, and
the command palette mounts no branch readers.
Closes#2250.
Watch-only devices are now denied repository checkout listings, including requests routed through another PC.
The sidebar no longer requests checkout data or displays branch names while in watch-only mode.
“New worktree” and “Open worktree…” actions are hidden for watch-only devices.
Worktree-list routes now refuse requests from watching devices. The client skips worktree-list polling and branch readers in watch mode, and the sidebar omits worktree creation and opening actions.
Changes: Watch-only worktree access
Layer / File(s)
Summary
Enforce read-only access on worktree-list routes server/index.ts, server/machine-api.ts, server/device-access.contract.test.ts, server/machine-proxy.test.ts
The local, alias, and remote worktree-list routes return 403 read_only for watching devices. Tests verify that the refusal does not reach the remote PC, while driving-device requests are forwarded.
Stop polling after watch mode or refusal src/lib/useWorktreeBranches.ts, src/lib/useWorktreeBranches.hook.test.ts
The hook skips listing requests in watch mode and stops polling after a read_only refusal. Tests cover polling, refusal handling, and role changes.
Wire watch mode into branch UI src/App.tsx, src/components/CommandPalette.tsx, src/components/Sidebar.tsx, changelog.d/watch-worktree-list-refused.md
The app passes watch mode to the command palette. The palette skips branch readers, and the sidebar clears cached listing data, skips requests, and omits worktree actions for watching devices. The changelog describes these changes.

Explanation
The title names the main change: watching devices are refused repository checkouts. It matches the changeset, which denies GET /api/worktree/list to watch-only devices on the local, alias, and proxy routes, and it references issue #2250. The title is a conventional-commit style fix, and it is specific enough for a teammate scanning history.
Full details: Linked Issues check
Explanation
Issue #2250 reports disclosure of unopened checkout paths and branches through local, local-alias, and remote-machine routes. The PR refuses worktree/list for watch-only devices in server/index.ts and blocks proxy forwarding in server/machine-api.ts. The contract and proxy tests cover refusal and driving access. The sidebar and command palette stop requesting branch listings while watching, and the hook test covers refusal polling and role changes. This prevents the reported disclosure across the specified paths.

…tching (#2250)
The palette stays mounted while closed, so branches it read while driving stayed shown and
searchable after the device turned to watching. They are now excluded and cleared then.
Merging 02ebf85 (closes #2250). A watching device is now refused a repository's checkout list: worktree/list answers 403 read_only locally, through /api/machines/<id>/, and before the remote proxy uses the PC's credential; the client stops polling on that refusal, starts over when the device's role changes, and hides New/Open worktree. Access control, so the merge pass reviewed it itself beyond the lane's omo + Codex approvals: with paired WATCH and DRIVE devices on a real server, every path variant (trailing/double slash, encoded separators, case, HEAD/OPTIONS/POST), the machine aliases, the remote-PC proxy and WebSocket frames gave WATCH no listing (403 or 404, zero listing RPCs, zero remote calls); DRIVE keeps it; device-access contract 17/17, typecheck clean. Note: a watching device still sees open workspaces' paths in the snapshot (unchanged); this closes the listing of checkouts not open in herdr and their branches. Not filed (LOW): Sidebar still offers "Delete worktree checkout" to a watching device (the server refuses it, 403); (CommandPalette keeping branch labels read before a drive-to-watch change was fixed in 02ebf85); the hook tests drain a bounded number of scheduler turns rather than awaiting completion.
