Two things, in one commit because both touch `src/server/api/computer-use.ts`
and the halves cannot be split without rewriting the file twice.
## The regression
`desktop/package.json` had lost `"claude-sidecar-[^/]+$"` from `mac.signIgnore`.
That entry is not a hardening nicety — it is load-bearing for attestation:
1. `build-sidecars.ts` signs the sidecar with an explicit
`--identifier com.claude-code-haha.desktop.sidecar`
2. `ClientAttestation.swift` compares that identifier EXACTLY in
`validDesktopChain`
3. without the exclusion, electron-builder re-signs the sidecar and drops the
flag, so codesign derives the identifier from the file name
(`claude-sidecar-aarch64-apple-darwin`), which never matches
Measured on the shipped 0.5.3 build: host and helper identifiers were correct,
the sidecar's was not. `validDesktopChain` backs BOTH `authorizeOneShot` and
`authorizeDaemon`, so this was not merely a broken permission probe — every
Computer Use call in that build failed closed with `unauthorized_client`.
The existing guard was a literal `toEqual` on the whole signIgnore array, which
does not survive an edit that changes the array and the expectation together —
exactly how the entry was lost. The replacement asserts the behaviour instead:
real sidecar file names must match some exclusion pattern, and the identifier
constants in `sign-identity.ts` and `ClientAttestation.swift` must agree.
`checkCuHelperPermissions` swallowed the failure into nulls, which the settings
page renders as a permanent "checking…" — indistinguishable from a probe still
in flight, and the only symptom this bug ever produced. It now records an
error-level diagnostic: the helper binary is present, so the user did nothing
wrong and the check still did not complete.
## App icons
Rows in the picker and the authorized list showed a letter tile. They now show
the application's own icon, resolved the way Finder does it: `CFBundleIconFile`
from Info.plist, the `.icns` under `Contents/Resources`, rasterised with `sips`.
`openTargetService` already does this, but its resolver is keyed on a
`TargetDefinition` and cannot answer for an arbitrary installed app, so the
path-only half lives in `macAppIcon.ts` and that service is left alone.
The endpoint takes a bundle id and resolves the path itself. There is
deliberately no parameter that names a file — it rasterises and returns bytes,
so its input surface is a security property, and a test drives paths at it.
Enumeration is shared across concurrent lookups: opening the picker fires one
icon request per visible row while the cache is still cold, and a plain
check-then-fill cache would walk every application root once per row.
macOS only, matching where this engine exists. The Windows list renders no icon
slot at all, and Linux is not a supported Computer Use platform.
## Verification
- 208 installed applications on the dev machine: 204 icons resolved; the 4
misses are background bundles (Adobe sync extension, a URL handler, an
updater, a token host) that ship no icon and correctly fall back
- check:server 3345 pass, desktop 4101 pass, check:policy 243 pass, lint clean
(the 2 failures in each suite are `*.golden.test.ts`, pre-existing on main)
- mutation-checked that the new guards actually fail: removing the signIgnore
entry, dropping the icon `onError` fallback, and breaking the in-flight share
each turn a test red
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.
Prevent repeated update checks from clearing the pending Electron update, recover the UI when relaunch does not exit, and keep public releases draft until all updater assets are uploaded.

Release is gated on the tag only. `bun run verify` runs on PRs and locally,
not at release time, so a failing quality gate no longer blocks publishing.
- release-desktop.yml: remove the quality-preflight job and its `needs`.
- release-workflow.test.ts: assert the release workflow does NOT run verify.

Unsigned builds ship manual downloads only, so the macOS auto-update zip
(~187MB) and the blockmaps just clutter the release page and dev artifacts.
- release-desktop.yml: stop attaching *.zip / *.blockmap to the GitHub
Release; users now see DMG/exe/AppImage/deb + install-macos-unsigned.sh.
- build-desktop-dev.yml: stop collecting *.zip / *.blockmap into the dev
artifact for the same reason.
- electron-builder still produces dmg+zip and the whole updater-metadata
pipeline (latest*.yml merge/validate) is untouched, so auto-update can be
re-enabled later by restoring the two asset globs.
- sync release-workflow.test.ts dev-artifact assertion accordingly.

Constraint: Desktop release artifacts must be built by GitHub Actions from version tags, not treated as local build outputs

Introduce the Electron desktop shell alongside the existing React renderer and local Bun server boundary. The migration keeps the DesktopHost contract explicit across Tauri, Electron, and browser runtimes while adding Electron main/preload services for dialogs, shell, notifications, updates, tray/window lifecycle, terminal, preview WebContentsView, app mode, and release/package validation.
The commit also carries the latest local main desktop command updates, including agent slash entries and hidden-by-default markdown thinking details, so the packaged Electron build matches the current main UX surface.
Constraint: React renderer, local Bun server, REST/WebSocket, and sidecar boundaries must remain reusable during the migration

Tauri runs the repository beforeBuildCommand during packaging, which invokes build:sidecars again after the explicit sidecar step has already passed. The Windows runner therefore still needs the same Bun compile cache override inside the packaging step so the repeated baseline runtime extraction stays on the runner work drive.

Rejected: Remove beforeBuildCommand from CI | that would diverge CI from normal Tauri packaging behavior.

Tested: bun test scripts/pr/release-workflow.test.ts; bun run check:policy
Not-tested: GitHub Actions Windows runner rerun after push.
Windows GitHub runners keep the checkout and Bun install cache on different drives, which can trip Bun's baseline compile-target extraction before Tauri packaging starts. Point desktop sidecar builds at the runner temp cache so dev and release workflows can still use the Windows x64 baseline runtime needed for older CPUs.
Constraint: Bun upstream still has an open Windows cross-drive extraction issue for compile target downloads.
Rejected: Revert to bun-windows-x64 | would reintroduce the older-CPU Illegal Instruction failure class.

The repository now has a measurable PR quality path instead of a loose set of
manual checks. Coverage, quarantine governance, provider smoke, desktop smoke,
and workflow wiring all produce durable reports that contributors and maintainers
can inspect without reconstructing terminal output.
This also fixes the desktop smoke current-runtime path so browser-driven smoke
runs use the desktop default active provider instead of forcing the official
current model, and records that runtime decision as an artifact.
Constraint: Default PR gates must remain non-live and contributor-safe while live model checks stay explicit.
Constraint: Release packaging is still GitHub Actions based, so release preflight must run before the build matrix.
Rejected: Make live provider or desktop smoke mandatory on every PR | secrets, quotas, and model availability are maintainer-controlled.
Rejected: Let PRs lower coverage baselines in the same change | base-branch ratchet comparison must remain authoritative.
Confidence: high
