At runtime, Linux never initializes Electron's +native updater; macOS and Windows verify the detached Ed25519 manifest, target architecture, and embedded signing +identity before giving a feed URL to `autoUpdater`. macOS additionally requires the native application signature, while +Windows releases are Authenticode-signed at both package and installer stages. diff --git a/apps/desktop/forge.config.ts b/apps/desktop/forge.config.ts index a2d291851..b376f5e7c 100644 --- a/apps/desktop/forge.config.ts +++ b/apps/desktop/forge.config.ts @@ -5,16 +5,89 @@ import { MakerSquirrel } from '@electron-forge/maker-squirrel'; import { MakerZIP } from '@electron-forge/maker-zip'; import { VitePlugin } from '@electron-forge/plugin-vite'; import { flipFuses, FuseV1Options, FuseVersion } from '@electron/fuses'; +import { readFileSync } from 'node:fs'; import { resolve } from 'node:path'; +import { fileURLToPath } from 'node:url'; +import { + readCompleteEnvironmentGroup, + resolveDesktopVersion, + resolveTrustedUpdateBuildConfig, +} from './src/release-config'; + +const desktopPackage = JSON.parse( + readFileSync(fileURLToPath(new URL('./package.json', import.meta.url)), 'utf8'), +) as { version: string }; +const releaseVersion = resolveDesktopVersion(desktopPackage.version); +const updateConfig = resolveTrustedUpdateBuildConfig(); +const macSigning = readCompleteEnvironmentGroup( + process.env, + ['PROPR_DESKTOP_MAC_SIGNING_IDENTITY'], + 'macOS signing', +); +const macNotarization = readCompleteEnvironmentGroup( + process.env, + [ + 'PROPR_DESKTOP_APPLE_API_KEY_FILE', + 'PROPR_DESKTOP_APPLE_API_KEY_ID', + 'PROPR_DESKTOP_APPLE_API_ISSUER_ID', + ], + 'macOS notarization', +); +const windowsSigning = readCompleteEnvironmentGroup( + process.env, + ['PROPR_DESKTOP_WINDOWS_CERTIFICATE_FILE', 'PROPR_DESKTOP_WINDOWS_CERTIFICATE_PASSWORD'], + 'Windows signing', +); + +if (macNotarization && !macSigning) { + throw new Error('macOS notarization requires macOS signing configuration'); +} +if (updateConfig.enabled) { + if (process.platform === 'darwin' && !macSigning) { + throw new Error('The macOS signed-update build must have a macOS signing identity'); + } + if (process.platform === 'win32' && !windowsSigning) { + throw new Error('The Windows signed-update build must have a Windows signing certificate'); + } +} + +const windowsSign = windowsSigning ? { + certificateFile: windowsSigning.PROPR_DESKTOP_WINDOWS_CERTIFICATE_FILE, + certificatePassword: windowsSigning.PROPR_DESKTOP_WINDOWS_CERTIFICATE_PASSWORD, + description: 'ProPR Desktop', +} : undefined; const config: ForgeConfig = { packagerConfig: { asar: true, + appBundleId: 'dev.propr.desktop', + appCategoryType: 'public.app-category.developer-tools', + appVersion: releaseVersion, + buildVersion: releaseVersion, name: 'propr-desktop', executableName: 'propr-desktop', + protocols: [{ name: 'ProPR Desktop', schemes: ['propr'] }], + ...(macSigning ? { + osxSign: { + continueOnError: false, + identity: macSigning.PROPR_DESKTOP_MAC_SIGNING_IDENTITY, + }, + } : {}), + ...(macNotarization ? { + osxNotarize: { + appleApiKey: macNotarization.PROPR_DESKTOP_APPLE_API_KEY_FILE, + appleApiKeyId: macNotarization.PROPR_DESKTOP_APPLE_API_KEY_ID, + appleApiIssuer: macNotarization.PROPR_DESKTOP_APPLE_API_ISSUER_ID, + }, + } : {}), + ...(windowsSign ? { windowsSign } : {}), }, rebuildConfig: {}, hooks: { + readPackageJson: async (_forgeConfig, packageJson) => ({ + ...packageJson, + version: releaseVersion, + }), packageAfterCopy: async (_forgeConfig, resourcesPath, _electronVersion, platform, arch) => { const applePlatform = platform === 'darwin' || platform === 'mas'; const executableName = applePlatform ?

Implemented the PR follow-ups. - DEB and RPM makers now explicitly use `bin: 'propr-desktop'` in [forge.config.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T18-16-06/apps/desktop/forge.config.ts). - Added a real Forge-config regression in [release-config.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T18-16-06/apps/desktop/src/release-config.test.ts), verifying both makers match `packagerConfig.executableName` and never resolve `@propr/desktop`. - Removed only the requested five EOF blank lines. - Preserved the native x64/arm64 workflow matrix. Verification passed: - Desktop typecheck - Desktop tests: 37/37 - Native Linux x64 DEB, RPM, and ZIP creation - `dpkg-deb`, `rpm`, and `unzip` inspection - DEB/RPM both contain `/usr/bin/propr-desktop -> ../lib/propr-desktop/propr-desktop` - All three artifacts staged with checksums successfully - Working-tree and PR-base `git diff --check` The temporary staging output was removed afterward to avoid committing ~300 MB of generated binaries; artifacts remain reproducible under the ignored `apps/desktop/out/make` directory. No commit was created.

Key changes: - PR finalization is unsigned and never receives the update private key. - Signing moved behind the `desktop-release` environment, restricted to trusted tag/publish events and pinned tag SHA. - Signed schema now binds manifest URL, target, version, feed bytes, artifact URL/size/SHA-256, and actual native signer evidence. - macOS Team ID/designated requirement and Windows Authenticode subjects are verified from produced/downloaded packages. - Runtime is safely check-only; Electron `autoUpdater` is never initialized. - Manifest query strings are rejected. - Added all requested security regression tests. Verification passed: - `npm run desktop:test` — 45 tests - `npm run desktop:typecheck` - `npm run desktop:package` - `npm run desktop:smoke:inspect` - `git diff --check` The local host lacks `fakeroot`, `rpm`, and `zip`, so native DEB/RPM/ZIP creation and macOS/Windows verification remain for the six-runner CI matrix after the changes are committed.

Implemented the runtime download hardening without committing or merging. Key changes: - Added streaming limits: 512 KiB manifest, 1 KiB signature, 1 MiB feed, and 1 GiB artifact maximum. - Added 30-second metadata and 10-minute artifact abort timeouts. - Rejects oversized `Content-Length`, chunked overflow, signed-size mismatches, and cross-origin final redirects. - Streams artifacts directly to private temporary files with incremental SHA-256 verification. - Cleans temporary files/directories on download, hash, and signer failures. - Preserved check-only behavior, Ed25519 verification, exact feed/artifact hashes, and native signer validation. Files changed: - [main.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T18-46-20/apps/desktop/src/main.ts:252) - [signed-updates.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T18-46-20/apps/desktop/src/signed-updates.ts:49) - [signed-updates.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T18-46-20/apps/desktop/src/signed-updates.test.ts:264) Validation passed: - Desktop typecheck - All 52 desktop tests - Runtime and packaging audits: 0 vulnerabilities - Linux x64 native packaging and fuse/executable inspection - `git diff --check` The full six-target native matrix cannot run locally on this Linux x64 host; it must rerun in CI after the follow-up is committed and pushed.

The keyboard listener now uses `useLayoutEffect`, ensuring it is current before the connected UI becomes interactive. Fixed the CI-only shortcut race in [DesktopExperience.tsx](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T18-56-24/propr-ui/src/desktop/DesktopExperience.tsx). The keyboard listener now uses `useLayoutEffect`, ensuring it is current before the connected UI becomes interactive. Validation passed: - Focused tests: 21/21 - Full UI suite: 496/496 across 69 files - UI typecheck - ESLint - Whitespace check No commit was created.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented all requested follow-up blockers on exact head `f94a38d11563a49157cb5feb8cbcb0eaedeee46b` without committing. Key changes: - Split secretless PR validation from preflight-gated production signing in [desktop-release-guard.yml](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T20-26-58/.github/workflows/desktop-release-guard.yml:24). - Added protected-main, immutable-tag, existing-release, reviewer, and tag-policy validation in [release-preflight.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T20-26-58/apps/desktop/scripts/release-preflight.mjs:54), using GitHub’s documented environment protection fields ([GitHub documentation](https://docs.github.com/en/rest/deployments/environments)). - Made macOS signing/notarization, Windows Authenticode, Ed25519 signing, signer pins, and signed publication mandatory for production. - Added repeatable ELF, PE, Mach-O, DEB, RPM, ZIP/NuGet, DMG, and package-payload architecture inspection in [release-architecture.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-29T20-26-58/apps/desktop/scripts/release-architecture.mjs:27). - Staging and finalization now independently reject wrong-architecture artifacts and invalid Squirrel metadata. - Corrected the AUMID to `com.squirrel.propr_desktop.propr-desktop`, tied to `executableName`. - Restored canonical `useEffect`, made UI tests deterministic through the title bar, and removed only the requested EOF blank line. Verification passed: - Desktop tests: 66 - UI tests: 500 - Desktop/UI typechecks - Runtime and packaging audits - Production Linux x64 package - Packaged executable/fuse smoke inspection - Workflow YAML parsing - `git diff --check` The six native CI targets and aggregate checksum job remain configured, but cannot run locally because this host is Linux x64-only and lacks `sudo` for the required native package tools. They will execute when the updated workflow runs in CI.

Key changes: - [release-preflight.mjs](/home/node/workspace/apps/desktop/scripts/release-preflight.mjs) now paginates repository rulesets, reads full rule definitions, and requires an active `refs/tags/desktop-v*` tag ruleset with update/deletion blocking, exact include/exclude semantics, and zero bypass actors. It re-reads the ruleset to detect mutation or deletion. - Environment deployment policies are fully paginated and must be exactly one enabled `tag: desktop-v*` policy with required reviewers and no protected-branch fallback. - [release-publish.mjs](/home/node/workspace/apps/desktop/scripts/release-publish.mjs) creates/reuses only an exact draft, uploads the checksum-derived allowlist, streams and hashes every remote asset, rejects duplicates/unexpected assets or tag drift, and publishes only after complete verification. Matching partial drafts are recoverable. - Final checksums now cover the signed manifest and signature. - Squirrel architecture validation derives the target from `propr-desktop.exe` inside the full NUPKG. Setup supports PE x86/x64/arm64 independently of payload architecture. - Added pagination, bypass/mutation/deletion, partial-upload recovery, digest mismatch, tag drift, and arm64 payload/bootstrap regressions. Verification: - `node --test ...release-preflight.test.mjs ...release-publish.test.mjs ...release-artifacts.test.mjs` — 21/21 passed. - `npm run desktop:typecheck` — passed desktop and UI. - `npm run desktop:test` — 78/78 passed. - Actionlint 1.7.12, checksum-verified, `-shellcheck=` — passed. - Targeted ESLint for changed scripts — passed. - `npm run desktop:package && npm run desktop:smoke:inspect` — Linux x64 package and fuse inspection passed. - `git diff --check` — passed. Repository prerequisites: - GitHub must expose a qualifying bypass-free tag ruleset to the preflight token; missing or ambiguous `bypass_actors` fails closed. - `desktop-release` must have required reviewers and exactly the `desktop-v*` tag deployment policy. - The genuine six-target matrix requires its native Linux/macOS/Windows x64/arm64 CI runners and signing/notarization configuration. - GUI sandbox launch smoke was unavailable locally because `xvfb-run` is absent and the packaged sandbox is not installed root-owned/setuid. Per the selected-record constraint, Linux payload layout, CRLF handling, README, and `DesktopExperience.test.tsx` were not changed. Consequently, `npm run lint -w propr-ui -- --max-warnings 0` still reports the pre-existing 401-line max-lines warning. No repository settings or real releases were created or modified.

DMGs require the exact application bundle layout. Windows Authenticode inspection now uses the canonical NUPKG executable. - F11: RELEASES parsing now requires the complete exact full-NUPKG set and verifies SHA-1 plus decimal size during staging, finalization, and signing. Validation passed: - actionlint - 93 desktop tests - 501 UI tests - Desktop and UI typechecks - Runtime and packaging audits: zero vulnerabilities - Linux production package and fuse inspection - Strict validation of a ZIP built from the real packaged Linux application - `git diff --check` Environment limitations: - Forge DEB/RPM/ZIP make is blocked by missing system tools: `dpkg`, `fakeroot`, `rpm/rpmbuild`, `cpio`, and `zip`. - The full suite reached 191/328 files without assertion failures, then blocked because Redis is not installed. - The six native CI jobs remain intact for rerun. - Windows thumbprint-policy changes were not included because the scope gate selected F9–F11 only.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the exact `ef737aacf73c77e4fa6c8a6d59dc3e5a16bbc1e0` follow-up without merging, syncing, or committing. Key changes: - Hardened DMG layout validation and added realistic Electron helper/install-link fixtures. - Added canonical Windows certificate/SPKI SHA-256 allowlists, signer equality checks, timestamp/chain validation, evidence propagation, and runtime enforcement. - Added missing, malformed, same-subject/different-key, mixed-signer, and tamper tests. - Preserved macOS Team ID/designated-requirement behavior and F9–F11. Passing locally: - Desktop typecheck - 97 desktop tests - 51 focused release/security tests - Runtime and packaging audits: 0 vulnerabilities - Linux package build and executable/fuse inspection - MJS syntax checks - `git diff --check` Host-limited gates: - Linux makers lack `fakeroot`, RPM, and ZIP tools. - Full suite reached 191/328 without failures, then stalled because Redis is unavailable. - Actionlint and six native matrix/aggregate finalization require CI; Docker and native runners are unavailable locally. No unrelated files changed.

Validation passed: - Focused architecture tests: 12/12 - Linux desktop suite: 101/101 - Desktop typecheck - Validate Changes’ Redis-free stages: release verification, 278 unit tests, 316 tunnel tests, 66 UI tests, CLI packaging - [actionlint v1.7.12](https://github.com/rhysd/actionlint/releases/tag/v1.7.12) - `git diff --check` The full suite reached 187/328 before Redis-dependent tests retried against unavailable Redis; this host has neither Redis nor Docker. The six native packaging jobs and native macOS x64/arm64 runs require CI runners and remain pending after the system commits the change.

Validation passed: - Desktop tests: 110/110 - Desktop typecheck - Validate Changes command set, including 278 fast tests and hosted-tunnel regressions - Full Suite: all 328 suites/files - Exact SHA-pinned actionlint - Sixteen-artifact `SHA256SUMS` verification - `git diff --check` The six real native package jobs require the post-commit CI matrix; this Linux runner cannot execute macOS and Windows native packaging.

Implemented the two requested DMG blockers on exact head `20fcc8cc9e2070921e0ffbc79a3e2b004c89da89`. - Added strict pre/post DMG identity, metadata, size, and SHA-256 verification around native inspection in [release-artifacts.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T00-53-41/apps/desktop/scripts/release-artifacts.mjs:160). - Hardened mounted layouts to allow only bounded framework-internal symlinks and require real canonical bundle/executable ancestors in [release-architecture.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T00-53-41/apps/desktop/scripts/release-architecture.mjs:803). - Added mutation/replacement, helper symlink, ancestor symlink, non-framework, escape/cycle/missing/case, real Electron framework, and complete SHA256SUMS regressions. Passed locally: - Focused staging/layout: 39/39 - Desktop suite: 115/115 - Desktop typecheck - Fast validation unit set: 278/278 - Release metadata verification - ESLint on all touched files - `git diff --check` Native macOS mounts, six native packaging jobs, full Redis-backed suite, and pinned-container actionlint require CI runners unavailable in this Linux environment. No commit was created; signer pins, evidence schema, six-target matrix, and Linux finalization remain unchanged.

Implemented the exact-head DMG follow-up without merging, syncing, or committing. Key changes: - DMG validation now uses a private `O_RDONLY | O_NOFOLLOW` held capability; inspectors receive no mutable pathname. - `hdiutil` and Linux aggregate 7-Zip inspection read inherited `/dev/fd/3`. - Pre/post checks retain device, inode, mode, link count, size, and SHA-256 while excluding ctime/mtime. - Validated bytes are copied through private `O_EXCL` publication temps, atomically published, and revalidated. - Added swap/restore, permanent replacement, in-place mutation, and native xattr/ctime regressions. - Added fail-closed descriptor-backed `hdiutil` probes to both macOS matrices while preserving all six targets and evidence schema. Changed files include [release-artifacts.mjs](/home/node/workspace/apps/desktop/scripts/release-artifacts.mjs), [release-architecture.mjs](/home/node/workspace/apps/desktop/scripts/release-architecture.mjs), and [desktop-release-guard.yml](/home/node/workspace/.github/workflows/desktop-release-guard.yml). Passed locally: - Focused artifact/layout tests: 40 passed, native xattr fixture skipped on Linux - Desktop suite: 116 passed, 1 native-only skip - Desktop typecheck - Aggregate finalization/SHA256SUMS tests - Validate Changes components, fast unit tests, hosted-tunnel regressions, and CLI package verification - actionlint - `git diff --check` Full Suite reached 191/328 with changes green, then blocked because this host lacks the CI Redis/Docker service. Native macOS x64/arm64 mount probes and the six native packaging jobs require their CI runners.

Passed: - Clean `npm ci` - Focused release/preflight/artifact/signed-update tests - Desktop tests, typecheck, and package - Actionlint 1.7.12 - Validate Changes’ non-container stages - Full Suite: all 327 files plus workspace suites - `git diff --check` The six native matrix jobs and real aggregate artifact finalization require their Linux ARM64, macOS, and Windows CI runners and could not run on this Linux x64 host. The configured Docker-based actionlint/Redis steps were unavailable; equivalent official binaries were used locally. Only the two intended F13 files are modified.

Implemented on exact head `fe26f938c7ea8c2ae276f0abbb5079fdede8b18b` without committing, merging, syncing, or changing release workflows. Key changes: - Strict bounded Squirrel `RELEASES` parsing and canonical filename/version/size/SHA-1 validation. - SHA-1 and signed SHA-256 computed from the same held no-follow descriptor before signer verification and handoff. - Explicit `applySignedUpdate` path; startup remains check-only. - Owner-private, atomic, fsynced, ten-minute single-artifact cache keyed to origin/channel/version/manifest digest/artifact SHA-256. - Cache reauthentication, signer/notarization checks, serialization, expiry, corruption and partial cleanup, and safe redownload. - Redacted runtime update failures without paths or tokens. - Adversarial RELEASES, cache, request-count, concurrency, ABA, link, corruption, cancellation, Windows/macOS/Linux behavior tests.

Implemented the follow-up changes on exact head `a0470086c6547fce67974f351d929c14de350ae2` without merging, syncing, or committing. Key changes: - Added Windows-native SID/DACL/reparse/link-count/full `FILE_ID_128` authority inspection and protected cache creation in [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T04-47-41/apps/desktop/src/windows-update-authority.ts). - Replaced security-sensitive numeric identities with bigint/canonical lossless identifiers. - Replaced raw installer path handoff with a one-shot held-byte capability. Windows retains a no-write/delete-share reader; signer verification uses private held snapshots; unsupported apply adapters fail closed. - Added serialized crash-stale cleanup, exact namespace allowlisting, case-collision detection, one-artifact enforcement, and total-byte quotas. - Added Windows-native owner/ACE/junction/lock tests and portable identity, quota, redownload, and swap/delete/hardlink/reparse/ABA fixtures. Local verification passed: - Clean `npm ci` - Desktop tests: 157 tests, 0 failures - Desktop and UI typecheck - Linux desktop package - Focused signed-update/Squirrel/cache/race tests - `git diff --check` Not claiming completion yet: - Windows x64/arm64 native tests, macOS native snapshot tests, six native package jobs, and 16-artifact aggregation require CI runners. - Actionlint was unavailable locally. - Full Suite passed through 192/329 files, then was stopped because this runner lacks the configured Redis service and Docker.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the requested follow-up changes, but completion is not claimed until native CI passes. Key changes: - Added explicit Windows-hosted DMG fixture authority while retaining real Darwin UID and 0700/0600 enforcement in [release-artifacts.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T05-22-58/apps/desktop/scripts/release-artifacts.mjs). - Replaced the split Windows reader/inspector with one `CreateFileW` exact-handle broker in [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T05-22-58/apps/desktop/src/windows-update-authority.ts). It verifies reparse state, owner SID, protected DACL/ACEs, link/type/size, volume and full `FILE_ID_128`, SHA-1/SHA-256, no-share locking, challenges, and final identity. - Removed brittle unsafe `Add-Type` compilation and added bounded enumerated diagnostics and native smoke/crash-restart coverage. - Bound apply-time consumption to broker-held bytes with fresh pre/post-launch challenges and no raw path. - Added bounded `opendir` inspection, whole-cache quarantine, capped cleanup, and overflow/depth/name/symlink-loop/restart tests in [signed-updates.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T05-22-58/apps/desktop/src/signed-updates.ts). Passed locally: - Clean `npm ci` — 0 vulnerabilities - Desktop/UI typecheck - Desktop suite — 166 tests, 157 passed, 9 native-platform skips - Desktop Linux package and packaged fuse/executable smoke - Focused release, cache, Squirrel and signed-update suites - `git diff --check` Outstanding mandatory CI gates: - Actual Windows x64 and arm64 broker/handoff/adversarial tests - Native macOS x64/arm64 held-snapshot tests - Six native unsigned packaging jobs and aggregate finalization - Actionlint, unavailable locally - Full Suite remainder: reached test file 188/329 with completed tests green, then blocked by missing Redis/Docker No merge, runtime sync, commit, or PR creation was performed.

Local validation passed: - Clean `npm ci` - Desktop tests: 172 tests, 161 passed, 11 platform skips - Desktop typecheck and Linux package - Release verification - Unit tests: 278 passed - `git diff --check` I am not claiming full completion: this Linux host cannot execute the Windows/macOS native cases or six-job/16-artifact matrix. Docker is also unavailable, blocking actionlint and isolated Redis; the local full-suite runner reached all 329 files, but `llmMetrics.test.ts` timed out waiting for Redis. The native matrix must now run and pass on both Windows and macOS architectures.

Implemented on exact head `8556ed513fc516839e99a6deb04b263241282e0e` without merging, syncing, or committing. Key changes: - Replaced per-entry PowerShell compilation with a process-wide persistent Windows authority broker. - Added bounded startup/compile deadline, strict ready/native-smoke frame, 10-second request deadlines, FIFO serialization, AbortSignal support, protocol/byte/frame caps, one-time restart, and shutdown reaping. - Preserved same-handle authority, hashing, held reads/apply, final verification, and no-share locking. - Added compileCount=1, warm aggregate latency, queueing, cancellation, crash/restart, framing, compile-failure, and leak tests. - Fixed Darwin assertions to compare exact `error.message`; fixtures now use the native x64/arm64 architecture. Changed files: - [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T06-49-51/apps/desktop/src/windows-update-authority.ts) - [windows-update-authority.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T06-49-51/apps/desktop/src/windows-update-authority.test.ts) - [release-artifacts.test.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T06-49-51/apps/desktop/scripts/release-artifacts.test.mjs) - [release-workflow.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T06-49-51/apps/desktop/src/release-workflow.test.ts) Passed locally after clean `npm ci`: - Desktop tests: 176 tests, 162 passed, 14 native-platform skips - Desktop/UI typecheck - Linux desktop package - Workspace preparation - Docs typecheck/build - `git diff --check` Completion remains pending CI evidence: this host cannot run Windows/macOS native jobs, and Docker is unavailable, preventing the pinned actionlint container and Docker-backed Redis Full Suite.

Implemented the follow-up changes without merging, syncing, or committing. Key changes: - Added an exact-production C# compile probe with bounded stages and legacy Windows PowerShell/C# 5 compatibility in [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T07-19-20/apps/desktop/src/windows-update-authority.ts). - Added strict setup/artifact purpose binding, zero-length setup support, exact positive artifact size/identity/SHA-256 enforcement, and live broker fault injection. - Replaced `cmd mklink` fixtures with native Node junction APIs and reparse assertions. - Added compile/startup, framing, cancellation, queued failure, restart, lock-release, and stale-state tests. - Hardened DMG detach cleanup and added a single bounded `hdiutil create` resource-busy retry using fresh private staging/output paths. - Added the compile probe before both Windows x64/arm64 suites in [desktop-release-guard.yml](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T07-19-20/.github/workflows/desktop-release-guard.yml). Local validation passed: - Clean `npm ci` - Desktop typecheck and all 180 desktop tests - Desktop package and fuse inspection - Focused cache, signed-update, Squirrel, release, DMG, and workflow tests - Runtime/desktop audits - Release verification, fast unit tests, tunnel regressions, CLI packaging, workspace build, and docs build - [actionlint v1.7.12](https://github.com/rhysd/actionlint/releases/tag/v1.7.12) - `git diff --check` Completion is not claimed yet: this host cannot execute Windows or macOS native jobs, the six-target artifact matrix, aggregate checksum job, or Redis-backed Full Suite. Both real Windows architectures must still report probe `ready`, production `compileCount=1`, and pass their complete native suites; Darwin x64/arm64 packaging must also rerun successfully.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the Windows broker bootstrap follow-up without merging, syncing, or committing. Key changes: - Replaced double-base64/double-bootstrap with one fixed PowerShell `EncodedCommand`. - Added fixed-width length prefix plus bounded raw strict UTF-8 C# transport. - Preserved stdin for the persistent serialized request protocol and compile-once child. - Added all requested stages, bounded stderr stage/index reporting, startup failure classification, deadlines, backpressure, and structured post-READY errors. - Added native stage injection, byte-at-a-time production-source fragmentation, multibyte UTF-8, partial/oversize/trailing source, and early-exit tests. - Preserved existing authority, purpose, junction, quarantine, Squirrel, and native workflow assertions. Changed: - [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T07-52-03/apps/desktop/src/windows-update-authority.ts:65) - [windows-update-authority.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T07-52-03/apps/desktop/src/windows-update-authority.test.ts:36) - [release-workflow.test.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T07-52-03/apps/desktop/src/release-workflow.test.ts:263) Local verification passed: - Clean `npm ci` — zero vulnerabilities - Release metadata verification - Fast unit suite — 278 passed - Desktop focused and complete tests - Desktop and UI typechecks - Linux desktop production package - `git diff --check` The hosted Windows x64/arm64 READY probes, full native suites, Darwin gates, and aggregate artifact jobs remain to be proven by CI. Containerized actionlint and configured Full Suite could not run locally because this host has neither Docker nor Redis, so I am not claiming hosted/native completion.

Implemented on exact head `b6fcd421a809713157826f736f69bb118d20c9bb` without merging, syncing, or committing. Key changes: - Replaced PowerShell stdin bootstrap with a directly spawned AnyCPU broker executable from committed [C# source](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T08-20-18/apps/desktop/src/native/propr-windows-authority.cs). - Added trusted-SystemRoot bounded compilation, held-output verification, deterministic manifest generation, packaged-helper inspection, and direct READY probes. - Added length-prefixed persistent binary framing, helper/process-image authentication, job-object cleanup, DACL/reparse/full identity/hash checks, and requested fault tests. - Packaged the helper and manifest as Windows extra resources and added exact NUPKG/layout inspection. - Updated the six-target workflow so Windows x64/arm64 build and directly exercise both source-built and packaged helpers. Local verification: - Desktop tests: 189 total, 168 passed, 21 platform-native skipped, 0 failed. - Desktop/UI typecheck: passed. - Linux production package and packaged smoke: passed. - Workflow YAML parse: passed. - `git diff --check`: passed. I am not claiming release completion yet: Windows x64/arm64 direct-helper execution, all six native artifacts, actionlint, Full Suite, and aggregate release gates still require the configured CI runners. Actionlint/docker were unavailable on this host.

Local validation passed: - `npm run desktop:typecheck` - `npm run desktop:test` — 190 tests, 0 failures - `npm run desktop:package` - `npm run desktop:smoke:inspect` - Focused authority, packaging, release, and signed-update tests - `git diff --check` I am not claiming completion: a separate OS-authoritative authenticate-to-spawn native lease/launcher boundary and full owner/DACL/Authenticode pin validation for compiler inputs remain incomplete. The six native jobs and aggregate exact-head revalidation also cannot run until these uncommitted changes are published.

Implemented the requested follow-up on exact base `5261a6cd6676b4e2fd344635fab4a3653bdfe37d` without committing or merging. Key changes: - Added the bounded kernel32 Windows-directory probe and compiler/reference leases in [propr_windows_launcher.cc](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T09-40-10/apps/desktop/src/native/windows-launcher/propr_windows_launcher.cc). - Added the per-architecture Node-API launcher build and manifest binding. - Replaced direct helper spawning with held-file native launch, suspended process image proof, explicit inherited handles, kill-on-close/single-process job, and retained leases. - Bound launcher architecture, hashes, Authenticode certificate/SPKI pins, packaging, NUPKG inspection, and release signer evidence. - Added compiler-root, manifest, launcher tamper, signer/pin, ABA, mutation barrier, job, pipe, and extra-child tests. - Removed the obsolete child-side parent PID/job authority path. Local verification: - `desktop:test`: 193 tests, 170 passed, 23 native-platform skips, 0 failures - `desktop:typecheck`: passed - `lint`, workspace build, and Linux desktop package: passed - `git diff --check`: passed - HEAD remained exactly `5261a6cd6676b4e2fd344635fab4a3653bdfe37d` I am not claiming release completion: Windows x64/arm64 compilation and all six zero-skip native jobs must run on the resulting committed CI head. The local Full Suite also could not complete because Redis was unavailable, and actionlint could not run because Docker was unavailable.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the follow-up on exact head `6c62a9e2eaeb97c8b9c4407c2bfd05bc773af107` without merging, syncing, or committing. Key changes: - Replaced the launcher’s pre-authority path `require()` with a separately packaged bootstrap that authenticates and locks the launcher before loading or invoking N-API initialization. - Moved compiler execution into the native boundary with held compiler/reference/source identities, Microsoft Authenticode/catalog provenance, suspended `CreateProcessW`, exactly three inherited handles, kill-on-close job assignment before resume, loaded-image equality, and leases retained through exit. - Compiles from an exclusive private copy of the exact held source bytes; manifest binds source hash and compiler certificate/SPKI/root-SPKI plus full file identity. - Rejects dangerous allow ACEs for arbitrary untrusted SIDs while supporting authenticated Windows servicing hard links. - Added ten bounded compiler substages without paths or diagnostics. - Canonicalized the Darwin temp fixture. - Propagated bootstrap and compiler provenance through package inspection, NUPKG validation, signing evidence, smoke checks, and manifests. - Added hosted x64/arm64 tests for preload, ACL, signer/catalog, compiler/reference/source barriers, image equality, teardown, and bounded failures. Configured native category counts per target: - Linux x64/arm64: 5 package-layout categories each. - Darwin x64/arm64: 12 native DMG-layout categories each. - Windows x64/arm64: 31 top-level authority categories each—8 build/compiler plus 23 runtime—with 18 compiler/source fault scenarios inside the build categories. Local validation passed: - `desktop:test`: 198 tests, 172 passed, 26 platform-native skips. - `desktop:typecheck` - Repository `build` - Fast aggregate unit suite: 278/278 passed. - Linux x64 desktop package and packaged smoke inspection. - Focused workflow, manifest, archive, bootstrap, and compiler-layout tests. - `git diff --check` The six hosted package jobs, Full, and GitHub Validate cannot run against these uncommitted workspace changes; their workflow gates are updated but are not reported as executed.

Implemented the six requested blockers on exact head `9d87bacb6a406cb75cacd90ffda587a17bd81be2` without merging, syncing, or committing. Key changes: - Added pre-load Windows bootstrap authentication with held-file identity, ACL/owner/reparse, hash, Authenticode certificate/SPKI, and malicious-initializer non-execution proof in [windows-update-authority.ts](). - Added servicing-aware system compiler probing, strict catalog/publisher authorization, held catalog identities, complete allow-ACE handling, and corrected environment-block separators in [propr_windows_launcher.cc](). - Bound compiler signer/catalog evidence to the immutable manifest schema throughout build, package inspection, runtime broker, and release validation. - Added real malicious bootstrap, arbitrary SID, object ACE, callback/conditional ACE, compiler provenance, and both injected-fault tests. - Added synchronized DMG publication and bounded transient `hdiutil verify` retries in [verify-darwin-image.mjs](). - Updated the six-platform workflow to exercise Darwin verification and both Windows injected faults. Validation: - Desktop tests: 203 tests, 174 passed, 29 platform-skipped, 0 failed - Focused authority/release tests: 45 tests, 0 failed - Darwin verifier tests: 2/2 passed - Desktop typecheck, packaging audit, and production package: passed - `git diff --check`: passed - Repository-wide suite reached Redis-dependent integration tests but could not complete because Redis is unavailable in this environment. - Windows and Darwin native execution remains delegated to their respective CI runners. All changes remain uncommitted as requested.

Implemented the requested follow-up without merging, syncing, or committing. Key changes: - Windows bootstrap authority now uses kernel-rooted `GLOBALROOT\SystemRoot`, an empty child environment, authenticated held system tools, and no `SystemRoot`/`windir`/`COMSPEC`/`PATH` authority. Added hostile-environment initializer coverage in [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T11-50-55/apps/desktop/src/windows-update-authority.ts:224). - Standalone catalogs now use `CERT_QUERY_CONTENT_FLAG_PKCS7_SIGNED`; embedded PE signatures remain embedded-only. Added same-root wrong-signer and swapped-catalog faults in [propr_windows_launcher.cc](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T11-50-55/apps/desktop/src/native/windows-launcher/propr_windows_launcher.cc:357). - Darwin verification canonicalizes fixtures, holds source and private snapshot handles, denies snapshot mutation/rename, uses fixed `/usr/bin/hdiutil`, and retains bounded busy-only retries in [verify-darwin-image.mjs](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T11-50-55/apps/desktop/scripts/verify-darwin-image.mjs:64). Validation: - Desktop suite: 205 total, 175 passed, 0 failed, 30 platform-native skips. - Darwin verifier: 3/3 passed. - Workflow assertions: 9/9 passed. - Desktop typecheck, ESLint, packaging audit, and `git diff --check`: passed. - Packaging audit: 0 vulnerabilities. The patched six-target CI matrix has not run because changes remain uncommitted as required. Therefore no per-target counts or skipped-stage credit are claimed. Full and actionlint also remain CI-pending; the local Full attempt was stopped when it reached a Redis-dependent test because this environment has no Redis service.

Implemented the requested follow-up on exact head `62847ea2a076f5e60420b33d9cb65cc29d887eaf` without merging, syncing, committing, or altering unrelated platform logic. Key changes: - [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T12-20-52/apps/desktop/src/windows-update-authority.ts:225) - Bootstrap proof now receives the exact Node-retained handle via inherited fd 3. - Type, reparse state, DACL/owner, link count, full volume/`FILE_ID_128`, bytes, hash, and content-mode signature evidence come from that object. - Node `dev`/`ino` are compared to returned handle identity. - Load-path and ancestor handles are leased through `require`; cached-module and split-handle substitution are rejected. - Removed `fsutil`, `Get-Item`, `Get-Acl`, and pathname Authenticode evidence. - Kernel-rooted PowerShell and its CatRoot catalog are handle-inspected with OS-only ownership/write authority and pinned Microsoft roots. - [propr_windows_launcher.cc](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T12-20-52/apps/desktop/src/native/windows-launcher/propr_windows_launcher.cc:362) - Catalog validation is cache-only/offline and rejects known revocation, untrusted chains, and wrong catalogs. - Added fixed substages: `CATALOG_ENUMERATION`, `MEMBER_TAG`, `CATALOG_HASH`, `WINTRUST_POLICY`, `REVOCATION`, `CATALOG_LEASE`, `SIGNER_PARSE`, `EXACT_PUBLISHER`, `ROOT_PIN`, `CERTIFICATE_PIN`, and `SPKI_PIN`. - Preserved standalone catalog parsing and held catalog leases. - Added forged/split identity, bootstrap replacement/hardlink/reparse/ABA, catalog-stage, wrong-signer, fake-tool, and malicious-initializer coverage. Verification: - Desktop tests: **177 passed, 0 failed, 31 platform-skipped**. - Desktop/root/workspace typechecks: passed. - Root and workspace lint: passed. - Linux x64 production package: passed. - `git diff --check`: passed. - Full reached **194/331 with no failures**, then was stopped because Redis is unavailable locally; not credited as a Full pass. - Windows x64/arm64, Darwin x64/arm64, Linux arm64, checksum aggregate, and actionlint were unavailable locally and are not credited. Hosted Windows must confirm `READY` and the native fault counts; any catalog failure will now identify its exact substage.

Implemented the requested follow-up without committing, merging, or syncing runtime. Key changes: - Preserved recognized `BUILD_COMPILER` substages through the outer probe catch; unknown exceptions remain redacted to `DIRECTORY_PROBE`. - Added immutable, architecture-specific Microsoft catalog filename, catalog SHA-256, certificate, and SPKI allowlists across native C++, Node, C#, manifest, and release validation. - Enforced OS-owned bootstrap authority, complete effective ACE parsing including inherited permissions, and rejection of current-user ownership or untrusted write/control grants. - Retained held catalog/member handles through final barriers and revalidated identity, ACL, path, and bytes after bootstrap initialization. - Added OS-owned protected ACL sealing for built and packaged Windows authority files. - Added real wrong-catalog, catalog-swap, same-object ABA, malicious initializer, current-owner, explicit-write, and inherited-write attacks with publication and leak assertions. Validation passed: - Full suite: all 330 non-live files plus the native workspace suite - Desktop tests: 178 passed, 32 platform-skipped - Windows authority/release focused tests - Desktop typecheck - `RELEASE_CANDIDATE=true npm run release:verify` - CLI release package dry run - `git diff --check` The exact remaining hosted Windows substage cannot yet be reported: jobs `99259890199` and `99259890051` ran the pre-change swallowed-stage code. After this worktree is committed and published, both Windows architectures must be rerun; any remaining recognized failure will now report its exact fixed substage. The real Windows native categories and six-platform checksum aggregate likewise require that hosted rerun.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implemented the requested follow-up without merging, syncing, or committing. Key changes: - Replaced PowerShell `Get-AuthenticodeSignature -Content` with raw-byte, held-handle native catalog/PE verification using WinVerifyTrust, CryptQueryObject, and CryptCATAdmin in [windows-update-authority.ts](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T14-05-56/apps/desktop/src/windows-update-authority.ts:318) and [propr_windows_launcher.cc](/tmp/git-processor/worktrees/integry/propr/pr-1972-followup-2026-08-30T14-05-56/apps/desktop/src/native/windows-launcher/propr_windows_launcher.cc:456). - Enforced `SE_DACL_PROTECTED=true`, canonical ACE ordering, generic mapping, owner/current-user checks, and rejection of inherited, dangerous, or unparseable ACEs. Removed synthesized `systemAcl` success. - Added real invalid-UTF-16 signed PE tests and same-root/wrong-leaf artifacts; removed synthetic hostile fault labels. - Added a machine-wide Program Files MSI with SYSTEM-owned protected ACLs, standard-user launch/authority smoke, and denied replacement/write/delete/rename checks through the actual installed artifact. - Added the machine MSI to release architecture validation and the fixed checksum aggregate, now exactly 18 entries. - Preserved recognized compiler substages through native/PowerShell/Node boundaries while safely redacting unknown failures. - Preserved the existing fixed catalog/certificate/SPKI allowlists, leases, catalog retention, cleanup, and non-Windows behavior. Verification: - Focused trust/release suites: **67 pass, 32 Windows-native skips, 0 fail** — 99 tests. - Desktop suite: **181 pass, 33 skip, 0 fail** — 214 tests. - Unit validation: **278 pass, 0 skip, 0 fail**. - Hosted-tunnel regressions: **316/316 pass**; UI: **66/66 pass**. - Desktop typecheck, release verification, CLI pack, Linux package/smoke, and `git diff --check`: passed. - Full suite: **330 pass, 0 skip, 1 fail** across 331 runs. `llmMetrics.test.ts` timed out because Redis was unavailable (`ECONNREFUSED 127.0.0.1:6379`). The historical Windows x64 run still only contains the redacted `BUILD_COMPILER:DIRECTORY_PROBE` result. The boundary that swallowed recognized substages is fixed and tested, but I did not credit Windows x64/arm64 native trust, real installation, or all-six-package counts: this Linux worker cannot execute them, and triggering new hosted CI would require committing/pushing, which was explicitly prohibited.

Implemented on exact head `5059c437661362670443983ffa8b173fdf332af0` without merging, syncing, or committing. Key changes: - Reproduced the x64/arm64 compile failure at `propr_windows_launcher.cc:651`: taking `&DRIVER_ACTION_VERIFY` was invalid because the SDK defines it as a brace initializer. Fixed it using a local `GUID`. - Added bounded `SPAWN`, `COMPILE`, `LINK`, `EXIT`, `TIMEOUT`, and `OUTPUT_LIMIT` diagnostics with sanitized file/line/error-code evidence. - Split held ACL policy into strict protected `package` objects and safely inherited `os` objects, including generic-right mapping and exact-role final rechecks. - Made the protected per-machine MSI the sole Windows release/update artifact. Removed MakerSquirrel, Squirrel startup handling, NUPKG/RELEASES metadata, and public Squirrel artifacts. - Added MSI install, upgrade, repair, downgrade rejection, failed-upgrade rollback, standard-user handshake/attacks, signer checks, and uninstall cleanup on native x64 and arm64 runners. - Made final aggregation reject either Windows fragment unless its installed-authority gate completed. Verification: - Windows header compilation: x64 1/0/0, arm64 1/0/0 pass/skip/fail. - Desktop suite: 174/33/0. - Windows build diagnostics: 10/3/0. - Release workflow + signed updates: 65/1/0. - Fast unit suite: 278/0/0. - Full: all 329 test files plus 1 native workspace suite passed; UI 501/0/0. - Validate-equivalent actionlint, shellcheck, release verification, CLI pack, core lint/build, desktop typecheck, and `git diff --check`: all passed. The hosted six-target artifact matrix cannot execute until the system commits this work. Its x64 and native arm64 Windows jobs now require the real installer lifecycle gate, and aggregation cannot report success when either is skipped.

Implemented the exact-head WinTrust fix without merge/runtime sync. - [`VerifyCatalogTrust`](/home/node/workspace/apps/desktop/src/native/windows-launcher/propr_windows_launcher.cc:673) now binds `member.hCatAdmin` to the retained SHA-256 admin and keeps the exact enumerated catalog alive through VERIFY/CLOSE. `pcCatalogContext` remains explicitly null. - Added native regressions for null/mismatched/released admin, wrong algorithm, foreign catalog context, and the passing exact held pair in [windows-authority-build.test.mjs](/home/node/workspace/apps/desktop/scripts/windows-authority-build.test.mjs:191). - Preserved offline cache-only policy, pins, diagnostics, ACL roles, packaging, and workflows. Verification: - Focused: 10 pass, 4 platform skips, 0 fail - Desktop: 174 pass, 34 platform skips, 0 fail - Validate fast tests: 278 pass, 0 skip, 0 fail - Validate tunnel tests: 316 pass, 0 skip, 0 fail - UI compatibility: 66 pass, 0 skip, 0 fail - Desktop/UI typecheck, release verification, CLI package, and `git diff --check`: pass Full and hosted Windows x64/arm64 gates could not run locally: Docker/Redis and Windows runners are unavailable. Full stopped before tests at `docker: command not found`; CI must provide the requested native, installed MSI, six-target aggregate, Full, and Validate counts.
