 ## macOS release signing and diagnostics

-The signed macOS configuration uses the required release environment instead of accepting whichever certificate appears first in a keychain. It rejects empty values, a malformed Team ID, a signing identity that includes electron-builder's unsupported `Developer ID Application:` prefix, and incomplete notarization credentials. Signed macOS packaging requires the configured identity and its private key. Runtime preparation applies that identity, a secure timestamp, and hardened runtime to every embedded Mach-O file; after signing the application, a deep strict check rejects any other leaf authority or Team ID before artifact creation. The signed fixed-target macOS installer commands create separate copies of the signed application and run two artifact lanes concurrently. One lane notarizes and staples the App before generating the ZIP and its update metadata. The other encloses its signed App copy in a signed DMG, then notarizes, staples, and verifies the DMG; its inner App has no individually stapled ticket. Both lanes must finish successfully before their artifacts reach the final directory and the release completion record is written. Signed directory-only commands also require notarization credentials and wait for Apple notarization and App stapling. The [parallel notarization decision](../../../.agents/notes/implemented/process/2026-09-09-parallel-macos-notarization.md) owns copy isolation and container ticket semantics. `CSC_LINK` must name a local p12 containing the Developer ID Application certificate and private key; URLs and Base64 inputs are not supported. `CSC_KEY_PASSWORD` is its export password, not an Apple account or login password; an explicitly empty value supports an unencrypted p12. Before building, packaging creates and unlocks a private temporary keychain, imports the p12, authorizes signing, and signs a small probe. Runtime and App signing use this keychain explicitly; existing login keychains require no setup or manual unlocking. Child processes receive its path without the p12 password. The keychain is deleted after success or ordinary failure; CI must clean temporary credentials after forced termination. Ephemeral CI writes the certificate and `.env.macos` from its secret store, restricts file access, and deletes both after the job; self-hosted machine presets retain private files outside the checkout. Ambient `CSC_NAME` and certificate discovery order do not select the release owner. Notary credentials may instead use electron-builder's complete Apple ID or keychain-profile strategy. The two macOS identity variables are also required when repeating the application check manually with `pnpm --dir apps/desktop run verify:mac-signature -- <path-to-app>`.

Signed macOS packaging requires the configured identity and its private key. Runtime preparation applies that identity, a secure timestamp, and hardened runtime to every embedded Mach-O file outside the notarized Computer Use helper bundles; for those bundles it verifies the deep signature, release identity, stapled ticket, and Gatekeeper acceptance without re-signing their files. A signed local build of a source that ships Computer Use therefore needs the notarized helper staged first with `scripts/cua-helper/package.ts` and `stage.ts`; an ad-hoc `build:native` output under `native/bin` fails this verification; after signing the application, a deep strict check rejects any other leaf authority or Team ID before artifact creation.

The two macOS identity variables are also required when repeating the application check manually with `pnpm --dir apps/desktop run verify:mac-signature -- <path-to-app>`.

 macOS signing visits real files without following Framework symlink aliases. PAK resources retain all shipped languages and are sealed by the enclosing Framework or application signature instead of receiving individual signatures. The [release policy](../../../.agents/notes/implemented/architecture/2026-08-25-electron-desktop-packaging-and-updates.md) owns the dependency patch and verification requirements.

 macOS runtime preparation caches verified single-architecture Mach-O signatures in `.desktop-build/targets/<target>/signature-cache` unless `DSH_DESKTOP_MACOS_SIGNATURE_CACHE_DIR` selects external storage. An explicit path must be absolute and already exist, contain no linked ancestors, and be owned by the current account with mode `0700` and read/write/search access; invalid or empty settings fail preflight without fallback. Omit the field to retain target-local storage. Keys include input bytes and permissions, the signing probe’s actual leaf certificate, identifier, entitlement bytes, macOS version, and signing tools and policy. Git commits do not determine reuse: uncommitted byte changes invalidate the affected file. Every hit verifies cached bytes, the strict signature, certificate, identifier, entitlements, secure timestamp and hardened runtime before replacing an unchanged input. Universal binaries are signed each time. Runtime integrity and smoke checks, App signing, and Apple notarization still run. The cache requires trusted local build storage. Cache corruption or unsafe links fail the build; stop packaging before deleting the affected cache directory and retrying. Successful signing stages prune complete entries to a one-GiB payload budget; interrupted temporary entries require manual removal. Concurrent eviction can fail a reader safely. Logs report hit, miss and uncached counts.

-Mac package commands print `DESKTOP_PACKAGING_RECORD` with a unique directory under `apps/desktop/.desktop-build/packaging-runs/`. After reading local configuration, each run retains `run.json` (published version, product version, Git commit, dirty-worktree flag, target and Node version), `events.jsonl` (timestamped phases, durations, parallel output attribution and proxy restoration), redacted child `stdout.log` / `stderr.log`, and `result.json` (overall outcome, stage results and artifact directory). Events also record pack concurrency and whether each proxy is configured. Logs survive failures and later builds; no automatic deletion runs. Missing `result.json` means completion is unconfirmed. Known credential values are redacted; environments and notarytool authentication arguments are not recorded. Runtime preparation records package staging, installation, materialization, signing, manifests, smoke checks, descriptor verification and cleanup separately. Nested phase durations overlap and must not be added together.

+CUA helper packaging prints `CUA_PACKAGING_RECORD` and creates its own record in the same directory before desktop installer startup. Its `run.json` identifies the helper target, product version and source commit; `events.jsonl` retains command and notarization phases, submission IDs and Apple results. `result.json` records success or failure. These records survive temporary payload cleanup, and the Desktop Actions diagnostic upload includes them even when helper preparation fails.

 App and DMG notarization each record a submission ID and separate `notarytool:upload:*` and `notarytool:wait:*` durations. Upload uses `submit --no-wait` and includes authentication, local validation, transfer and server acceptance; it is not pure transfer time. Waiting starts after that command returns and includes polling and remaining Apple processing; Apple can start processing before upload submission returns. Apple status and diagnostic logs are retained, including rejection; signature checks, acceptance checks and stapling remain owned by `@electron/notarize`. Directory-only package commands use this same measured App notarization path. Individual subprocess output remains live in the terminal, while phase failures and nested errors are retained in the journal. Both platforms record parent-process packaging failures and print redacted diagnostics, including proxy recovery instructions, to the terminal. The configuration-only `check:package` command creates no run log.

The payload smoke resolves the search tool’s ripgrep executable and verifies text search and file enumeration. Signed Windows builds run these checks after dependency signing; other builds run them during `prepare:dsh`. The [Host smoke](../scripts/smoke-runtime.ts) creates DOCX, XLSX, and PPTX inputs with bundled Python, converts each through the real Office provider, and checks PDF output. Every assembled application, including directory and unsigned builds, repeats the payload and Host checks against ASAR. Archive integrity checks compare the complete archived descriptor with preparation, file bytes and membership in both archive and unpacked trees, recorded executable flags for archived files, and physical permissions for unpacked files.

 Desktop dependency overrides are declared separately in the patch-policy module, not inferred from patch versions. The pi-ai constraint keeps its runtime version at the version qualified by the shared patch. Desktop still resolves a fresh runtime lockfile for each build, then installs with `--frozen-lockfile`; dependency resolution across separate builds is not yet reproducible. CLI packed-installation tests and other distribution flows retain their own configuration.

-Every package command builds the repository, packs the first-party production closures rooted at dsh and the private Desktop Host, and prepares the target Electron distribution plus primary-runtime with its shared pnpm CLI. `prepare:dsh` installs the production graph once at build time, prepares materialized packages for electron-builder to archive under `app.asar/dsh`, removes package-manager metadata, and writes `desktop-runtime.json` with shared package versions and final file hashes. Signed macOS builds sign and verify native files before inventory generation; electron-builder excludes this already-signed tree from nested re-signing. Resource mappings explicitly include `dsh/node_modules`, which the default root-directory filter omits; the prepared runtime inventory is checked after native signing. Native executables and libraries are unpacked beside ASAR; Python, standalone Node and pnpm remain in external runtime resources. Windows packaging checks every prepared PE against its ASAR unpacked entry and byte-identical disk copy, including unsigned builds. Builder glob rules match braces in PE filenames as single-character wildcards, so a matching neighboring file may also be unpacked. Prepared runtime smoke uses the verified target descriptor rather than the build host architecture.

 A bundle's page shows the bundle's detail document first among its sections, without a heading of its own: the bundle's long description in the current UI language, as Markdown with images. It is the Markdown file that `meta.detail` in the bundle's `locale/<language>.json` names, otherwise the bundle's README, read by [`pluginManager.readBundleDetail`](../../boot/plugin-manager/README.md#bundle-detail-documents) in the [document order of `dsh-plugin-detail`](../../util/plugin-detail/README.md#document-order); the repository a bundle declares is not read. An installed bundle's document comes from its own files without network access, and an on-demand Official bundle's from the npm file CDNs at its offered version. While the document loads the section shows three skeleton lines; a bundle without a document shows no section; a failed read names its reason with **Retry**. Raw HTML is omitted, relative images load from the Host beside the document, relative links stay text, and a document taller than the section's height limit scrolls inside it. A bundle whose files are not installed, such as an on-demand Official bundle, is read from the npm file CDNs: its read first asks the Host's registry comparison and, when npmmirror answered fastest, reads it and its images from npmmirror first. An installed bundle's read does not wait for the comparison. Any profile change and a connection reset read shown documents again.

-On-demand Official cards follow package discovery visibility and are available offline before installation. In Add plugin, a bare Official package name uses the Host’s matching-version or source-checkout target, retains the selected registry, and offers Enable now after installation. Turning one On opens the existing install progress dialog, installs the [target offered by the running Host](../../boot/plugin-manager/README.md#use-this-package), and selects its layer. The same registry fallback, cancellation, and script-approval controls apply. Turning Off keeps the dependency installed; Remove is separate. A different version or development link source offers **Update**; details show current and offered sources and versions. An update removes the installed package and installs the offered one with the same selection, reporting whether a restart is required; when the installation fails after the removal, the package stays uninstalled. Missing or unreadable packages keep their recorded dependency source alongside the diagnostic. An enabled bundle can still be switched Off when its checkout target is unavailable.

 The helper supplies bounded 64-pixel PNG application icons for permission prompts and saved-application lists. Icon reads do not launch an application or inspect its windows; icons do not determine reusable consent.

Existing connections retain their running application generation when another build updates `current.json`. When bundled inside another `.app`, it starts from a verified standalone copy; see [application storage](native/README.md#build-and-service).

 Permission requests open the selected privacy pane and a native floating guide. The guide selects the largest settings window once and follows that window by ID. It uses the normal window level, ordered immediately above the selected window so authentication dialogs remain above it. Placement reads window bounds without requesting Accessibility access. The guide stays hidden until the settings window is identified; a failed settings-open request displays manual navigation instructions independently. A material alpha mask gives the panel and its shadow rounded corners. The latest request replaces the shared guide, and only its owning connection can close it during cleanup. Navigation is attempted even when the application is unavailable, and the page reports that failure. Already-granted permissions open settings without a guide; explicit settings navigation dismisses previous guidance. A rejected settings-open request reports `SETTINGS_UNAVAILABLE`; missing or replaced application targets report `APPLICATION_UNAVAILABLE`. System Settings owns drag acceptance and any relaunch requirement.

-This package is an optional macOS dependency. For local development, run `pnpm --dir packages/experimental/cua-macos run build:native` to generate an ad-hoc-signed application and `current.json` under `native/bin`. Release packaging requires `--identity "Developer ID Application: <name> (<team>)"` and notarization; see [native build and service](native/README.md#build-and-service). Installed packages preserve the distributed signature. Source preparation requires Swift and Python 3 from Apple Command Line Tools.

The Host runs the application executable with `--ensure-shared`, which launches the background service through LaunchServices. The service exits after its last connection finishes cleanup. When the helper is nested inside another `.app`, its launcher copies the complete signed bundle to `~/Library/Application Support/DeepSeek Harness/Computer Use/<runtime-key>/` before starting it. Each immutable generation is verified against the executable hash and application signature; earlier generations remain available for running installations. This keeps both macOS permission services attributed to the helper. A failed verification stops startup; remove the named cached generation before retrying.

 Source checkouts build with `--variant dev`, producing `DSH Computer Use Dev.app` with bundle identifier `com.deepseek.harness.computer-use.dev`. Development and release builds default to ad-hoc signing. Ad-hoc requirements contain the code hash, so changed binaries can require new grants.
