An approved team handed every member its instructions at the same moment,
so members whose tasks depended on unfinished work started anyway: the
second and third layers of a plan ran before the first, a member could mark
a blocked task in progress, and results only ever went to the lead. The
official CLI states dependencies in tool prompts and nothing more, so the
plan the user approved was not what ran.
- A member whose tasks all wait on other tasks gets its instructions only
once one of them is ready. What the lead or a teammate sends it before
that waits in its inbox and arrives with the instructions; only the user
writing to it, or a shutdown request, reaches it earlier. This survives a
Stop and a server restart.
- TaskUpdate refuses a teammate that starts or completes a task while a
task it is blocked by is unfinished. The lead is not held to it.
- Each member is told who waits on its tasks and to send them its result
before completing, so a dependent member starts with that result in
hand. A member that starts without one is told whose is missing.
- A member that exits after approving a shutdown request is no longer
recorded as failed, and the lead gets no failure notice for it. The
shutdown-approval schema keeps leaving out the desktop backend on
purpose, now documented and tested.
- TeamPlan tells the lead that a dependent member's prompt is delivered
when its dependencies are done.
Long Agent Teams runs lost members for good: a truncated provider stream
ended a member's turn with nobody to wake it, the desktop Stop button and
every lead restart killed all members and marked the plan interrupted,
mail sent to a stopped member landed in an inbox nothing read, and a lead
kept inside one long turn never saw member reports. Aligned with the
official CLI 2.1.284 and verified with DeepSeek Flash through a
fault-injecting proxy.
Stream recovery
- Re-send a stream that breaks before any tool ran (proxy truncation,
transport errors), with the existing retry budget and backoff; the
desktop drops the discarded attempt's tool cards and todo update.
Desktop team runtime (teamPlanRuntime)
- The server supervises members: a stopped member restarts from its own
transcript when messaged; transient failures continue automatically
(15s/45s/2m/5m/10m) and only exhausted retries reach the lead; ready
dependent tasks wake their owner; a crash-loop guard ignores user stops.
- Stop pauses the team instead of ending it; the lead's next user message
is followed by a notice listing the stopped members and their open
tasks. Lead restarts (model/permission switch, crash) keep members;
server restarts re-own the team. Teams end on /clear or session delete.
- Approving a plan no longer races a concurrent plan read into
"Launch ownership was lost".
Mailbox and messaging
- Atomic inbox writes, identity-based read marking, read history files,
idle notifications with result/failureReason, and write failures
reported instead of "Message sent". External builds keep the official
between-turn delivery to the lead.
- SendMessage resumes non-running in-process teammates from their
transcript, notes restarting desktop members, queues mail for members
of a plan awaiting approval, and rejects unknown names.
CLI in-process teammates
- Compaction uses the teammate's own controller and real history and no
longer kills it on error; failed turns are classified and continued;
the turn-end mailbox drains as one batch; one durable transcript per
teammate.
Lead behaviour
- An unmet /goal ends the lead turn while members work, so member reports
arrive; WaitSessions on own team members returns immediately.
Desktop UI
- Member states for stopped, auto-retrying and failed, with reason,
countdown and recovery hint in all five locales.
Tests and tooling
- Regression tests for every behaviour above; module mocks in four test
files are restored after use so the single-process coverage run is not
polluted; the desktop smoke asserts the new Stop semantics.
Page transcript and trace reads, bound UI caches and retained task records,
and replace full-file background polling with incremental projections.
Preserve recovery and ownership semantics across pages and cancel stale work.
Route native-only changes through macOS checks and verify relocated cursor resources in final packages. Reject resources that escape the app and exercise visible click feedback against a disposable native receiver.
Connect the regressions to required checks and capture shell fixture output through temporary files.
Revert efe5cae19 so existing sessions remain usable and models can be
switched without protocol admission checks. Retain the additive index
schema for already-upgraded caches and rebuild their summaries.
Add a persistent isolated JavaScript worker for native app actions and batch
known operations without a model round trip between each input. Preserve
per-cell context, native errors, screenshot coordinates, and image types.
Align macOS gesture, key, inventory, capture, scroll, and clipboard behavior;
include a signed native receiver fixture and compiled sidecar regression tests.
Keep the Windows pixel route and fix cancellation with session-owned mouse
cleanup, lock revalidation, and portable signing-fixture tests.
main is 87 commits ahead and carries a large amount of fixed behaviour this
branch should not be re-deciding. The rule applied throughout: this worktree
owns Computer Use, main owns everything else.
Only 12 files were touched on both sides, and Git merged all of them without
reporting a conflict — but two of those silent merges were wrong, and neither
was visible until the checks ran.
`desktop/src/api/client.ts` ended up with two `apiGetBlob` implementations.
Both sides had independently hit the same problem (an `<img src>` pointed at an
API endpoint is a cross-origin subresource, so it carries no Authorization
header and the server's fetch-metadata policy refuses it) and both had written
the same fix. Git saw two additions in different places and kept both, which
does not even compile. main's version survives: it builds its headers through
the shared `buildHeaders()` rather than assembling them inline, so it inherits
whatever main adds there later.
`src/server/api/computer-use.ts` still imported `runtime/mac_helper.py` and
`runtime/requirements.txt` as compile-time text, both deleted on this branch.
Nothing at runtime referenced them, which is why the deletion looked clean; the
bundler resolves those imports when the server module is loaded, so the failure
surfaced only when the tests actually imported it. That path is now Windows-only
in the same sense the rest of the Python bridge is, and it also ships
`win_cursor_badge.py`, which the badge needs because it runs as its own process.
`computer-use-requirements.test.ts` drops its darwin half for the same reason —
the pins it guards still matter, but only one requirements file is left.
Verified: server 3869 tests / 331 files, desktop 4612 tests / 319 files
(lint + tsc + build), Swift 272 XCTest + 14 Swift Testing, Python 25.

The smoke waited on `textarea`, but the composer became a ProseMirror
contenteditable (MentionComposer) some time ago, so the selector could
never match. The lane hung for its full 30s timeout and failed on every
run — the screenshot it captured on the way out showed the app rendered
and idle, which is what makes this easy to misread as a UI break.
Target `[data-composer-editor]`, the attribute the editor puts on its
editable node and the same hook composerTestUtils already drives.
Rebuilt against main so the branch carries the Computer Use work and no other
divergence. Three unrelated efforts had been sitting uncommitted in this
worktree and were swept into an earlier commit; they are preserved on
cu-worktree-full-backup and belong on their own branches — adapter control
credentials, Electron asar sealing, and the sidecar code-loading audit. Every
file outside Computer Use now matches main exactly.
The engine
A Swift helper drives apps through the accessibility tree, with coordinate
actuation for the Chromium and Electron apps whose tree is a bare window
frame. Ten primitives matching the shape Codex uses, so an app's guidance and
the model's habits transfer.
Coordinate actions resolve their target window once and refuse when none can
be named. The unbound event they used to fall back to is discarded by custom
renderers, so a minimized target produced a whole session of "Action
completed" with nothing behind it.
Input acceptance is established for typing and key presses as well as clicks:
each MCP call is seconds apart, so the keyboard cannot inherit the focus a
click established. The synthetic focus notification is gated on the target
not already being active — sent unconditionally it names window 0 at an app
that already owns a key window, and nine window-bound clicks were discarded
with the traffic lights fully lit.
State the model can trust
An off-screen target says so, and says which tools still reach it: element
actions need no on-screen geometry, so an app with a real tree can still be
driven from the Dock. A fully covered window is recovered once, then left
alone — burying it again is the user wanting their screen back. A repeated
capture is reported with the cause that actually applies rather than both,
because coverage is something we compute.
Signing
The helper is signed under a stable identity before electron-builder sees it,
and excluded from re-signing: macOS ties Accessibility and Screen Recording
grants to the signing identity, so rotating it drops both on every update.
Discoverability
The desktop slash menu falls back to a directory scan while a session's CLI
has not started, which is when the menu is first opened. Built-ins and
bundled skills live in the binary, so /computer-use was absent until after
the first message.
`check:agent-flow` proves the protocol with the mock CLI, which is what makes it
CI-safe and lets any contributor run it with no credentials. It cannot prove the
thing this product actually is: a desktop agent talking to a real model. That can
only run where the credentials are, so this lane is local and manual by
construction — registered in no quality-gate mode, referenced by no workflow, and
live.test.ts fails if either changes.
Six scenarios, sharing the existing harness rather than a second copy of it:
first turn, permission allow, permission deny, interrupt, reconnect, and history
recovery. Prompts induce the behaviour instead of dictating it, and assertions
only look at protocol shape and side effects on disk — never at generated text —
so the lane passes on any provider, including a local one. The three flows left
out (api-error, tool-error, runtime-select) each carry a written reason, because
a silently missing flow reads as a covered one.
Spending someone's quota is the failure mode worth engineering against, so the
runner refuses to guess: no implicit fallback to the active provider, an ambiguous
selector is an error rather than a pick, and without --yes it prints the provider,
model and config path it would use and exits without sending anything. User state
is copied into a throwaway config dir and the real ~/.claude is fingerprinted
before and after — a run that writes to it fails loudly instead of being cleaned
up quietly.
Not yet run end to end: the local LM Studio endpoint answers 502 here, so the six
runners have only been verified for structure. Target resolution, the
confirmation gate, and lane placement are covered by 14 tests that need no
provider at all.
Coverage answers "is this tested", never "should this exist", and the difference
cost real work. BackgroundTasksBar, SessionTaskBar and TeamStatusBar lost their
last import in 56a4be3d1 when SessionActivityPanel replaced them. Nothing noticed:
598b968ee then wrote tests for two of them — "cover the components left at zero" —
purely to lift changed-lines coverage past the gate, and c712f5285 restyled all
three during the UI redesign. 577 component lines plus 348 test lines were kept
alive for code no user could reach, along with nine translation keys carried in
five locales.
Delete all of it, and add the check that would have caught it: every .tsx under
src must be reachable by static import from a script tag in index.html or
gallery.html. Reading the entries out of the HTML rather than hardcoding them
means a new entry brings its whole subtree with it. The allowlist is empty and
should stay that way.
Scoped to .tsx deliberately. The .ts side has entry points a static graph cannot
see — workspaceDiffHighlight.worker.ts is a `new Worker(new URL(...))` target and
src/preview-agent/** is built into its own bundle — so covering it needs an
allowlist, which is where this kind of check goes to die.
Two mutations: putting BackgroundTasksBar.tsx back names it exactly, and breaking
ENTRY_HTML trips the entry-point guard first so the reader is not sent hunting
through 160 falsely-unreachable components.
Also drops the now-dangling desktop/src/mocks/ coverage exclusion, deleted in
33df50b9c.
Independent QA on 3264db10 flagged changed-lines coverage at 86.17%
(5539/6428), under the 90% gate. Two causes, handled differently.
`desktop/src/dev/` joins `mocks/` and `types/` in the coverage exclusions.
It holds the component gallery — 260 of the 889 uncovered lines, and by
far the largest single contributor. Vite never bundles it (the build
input is `index.html` alone), and unit-testing a page whose whole job is
rendering every primitive would assert that the primitives render, which
their own tests already do. Excluding it is a scope correction, not a
threshold adjustment.
The rest are three components this branch touched that had no test file
at all. They now have one each, covering the behavior that changed:
- `BackgroundTasksBar` — drawer open/close including Escape, the running
vs finished split, dismissed-key filtering, and that clearing reports
every finished key while keeping the drawer open if work continues.
- `TeamStatusBar` — the progress bar's `aria-valuenow`, lead exclusion
from both list and count, and that it greens on "nothing running"
rather than on 100%: one completed plus one errored is done at 50%,
which is why `tone="auto"` would have been wrong here.
- `MarketSkillDetail` — skeleton semantics, retry, install/uninstall by
`installState`, and the disabled+spinner state mid-install.
Changed-lines coverage: 91.06% (5610/6161).
The QA report's second finding, `check:impact` blocking on a missing
`allow-cli-core-change` label, is an artifact of the branch trailing
main. `check:impact` diffs against `main`, so main's own newer commits —
9 files under `src/` — are counted as this branch's. Against the merge
base the same evaluator returns `areas: desktop, blocked: false`. No code
change here; the branch needs a rebase before it can pass that lane.
Avoid Bun filter-mode repository scans that exhaust macOS file descriptors and corrupt subprocess test evidence. Apply rooted filters across server, contract, coverage, persistence, policy, desktop native, and adapter test entrypoints.

Introduce the Electron desktop shell alongside the existing React renderer and local Bun server boundary.

Desktop startup can fail before React mounts on older WebViews, so an HTML-level watchdog now renders startup diagnostics even when the module bundle never reaches the app code. Persistent provider migration now imports legacy root provider config into cc-haha-owned storage without deleting the old source file, and plugin marketplace cleanup refuses obvious corrupted cache roots or outside paths.
Constraint: User explicitly accepted the current reviewed state for landing despite remaining review concerns.
Constraint: Global ~/.claude state is user-owned and protected; automatic repair must avoid deleting shared config, transcripts, skills, MCP, plugins, OAuth, adapters, and teams.
