What: Chrome observation is opt-in per Mac, native Chromium key reads run in a worker, and the desktop bundle regression covers every configured worker.
Why: The original mirror could block startup on Keychain consent; its new worker also exposed a stale four-worker bundle-test fixture.
So what: The planner reviews head 2a511fa8e900b28fdc949d6b03305b7348296b59 on current main, checks its new CI, and owns any approved rollout and Rocky live proof.

Refs #541 (closes after the live Rocky startup proof). Refs #520 and #530.

Rebased merge-free onto origin/main at 1e83a3169f77d5dbbd6727c929ffb8b0c1118754. The sole conflict was concurrent appended paths in scripts/fork-upstream-edits.txt; both main's secret/OAuth/research paths and #541's entries are retained. The existing implementation commits otherwise replay unchanged. No version bump.

A nonempty chromeCookieKeyCommand enables the Chrome source on that machine. Missing, invalid and empty commands leave it off; desktop-to-environment mirroring remains available. Shared Chromium key resolution runs native Keychain access in a worker for both one-off imports and the mirror fallback. The argv command already runs in a child process. No protocol, server or web-component behavior changed.

CI repair: Test job 118154631974 failed with [UNRESOLVED_ENTRY] Cannot resolve entry module src/preview/BrowserImport/ChromiumKeychainWorker.ts. The build config declared the new worker, but the synthetic fixture only created four older workers. The Check job merely propagated test: failure; it has no separate defect. The fixture now derives worker paths from the real bundle configuration, creates their nested directories and computes the shared-module import relative to each path. It loads every emitted worker and still asserts desktop startup occurs exactly once. The new touched upstream test is allowlisted and assigned to the existing mirror owner.

Comparison: before repair, the rebased candidate reproduces the same unresolved-entry failure (1 failed / 1 passed). The byte-identical unmodified test and bundle config from 1e83a31 pass (2/2); main's CI also passes. After repair the bundle regression passes 2/2. This CI failure is introduced by this PR, not pre-existing on main.

Scoped vp lint on all 10 changed JavaScript/TypeScript files and vp fmt --check on all 15 supported touched files pass. No web component changed, so React Compiler coverage and screenshots do not apply. Website/SEO impact: none; desktop startup and existing guidance only. The unresolved-key regression uses actual DesktopApp.program and BackendManager with synthetic process/HTTP/window boundaries; native Rocky acceptance remains unverified.

The original upstream check inspected ChromiumKeys blob 0d91ebe5a3746b0e47ddc7da47efa34d3d05681c; upstream #21028 covers a different safeStorage path and no upstream fix was ported. The original three failing-before source/worker regressions and synthetic blocked-worker artifact probe remain recorded in the earlier #541 handoff. This follow-up used existing cached dependencies with an explicit Electron path, with no installs, launches, restarts, dev servers or live Keychain/cookie access. Full Knip now passes without changing dependency declarations; #544's earlier setup-limited findings no longer block this candidate.

Range-diff maps 749e3369e1 to 4be08dfb65 with only allowlist context changed, and 0727249d45 to identical patch 2265c34feb; 2a511fa8e9 adds only the bundle-fixture repair and its fork ownership. Pushed with an explicit lease against remote 0727249d45c20bcb044b80054c835390d2aae7c1.

Opus review/independent success covered the old head 0727249d45, not this new candidate. Fresh independent exact-head review and CI results remain planner-owned. No merge, production artifact, installation or live rollout is claimed; retain the task worktree until the planner merges and retires it.

Requirements and who asked: The planner requests rebase onto current main, resolution of both failing checks, preserved worker/startup isolation, focused proof, vp pack and a lease push.
Deleted: The stale hand-maintained worker fixture list, assumptions that successful production bundling also proved the synthetic bundle test, and a separate fix for the aggregate Check job.
Bottleneck: The synthetic bundle fixture failed before exercising the worker/startup isolation assertion, blocking CI and fleet rollout.
Checked myself: Both complete failed-job logs, rebased failure, main test/config comparison and green CI, corrected bundle test, 192 focused tests, actual vp pack, desktop typecheck, scoped lint/format, full Knip, range-diff and fork checks.

Implemented with GPT-6.1 Sol through the Codex harness.

Independent review at 0727249d45: PASS (Claude Opus 5.5). Grok not available (402 balance exhausted).

• A fresh install with no key command never selects the Chrome source, reads a key or spawns anything (DesktopCookieMirror.ts:174); the mirror starts after whenReady.
• Every Keychain read goes through the worker (ChromiumKeys.ts:72-107), for both the mirror key cache and the one-off import (ChromiumCookies.ts:290); the key command is an async child process with a 15 s timeout.
• vp pack emits dist-electron/preview/BrowserImport/ChromiumKeychainWorker.cjs at the path main.cjs resolves; @napi-rs/keyring stays external.
• Head passes 7 files / 35 tests; restoring pre-fix ChromiumKeys.ts and DesktopCookieMirror.ts fails 9 tests across 4 files.

Unproven: a worker_threads worker loading the native keyring addon from the signed macOS app; Rocky's live run settles it.
Optional: quitting during a pending one-off import prompt may wait for it; a cancelled import leaves its prompt on screen; the null-command Keychain branch in ChromeCookieKey.ts:51 is now dead.

What: PR #545 is rebased onto 1e83a3169f77d5dbbd6727c929ffb8b0c1118754 and lease-pushed at 2a511fa8e900b28fdc949d6b03305b7348296b59.
Why: The stale four-worker synthetic bundle fixture caused Test to fail; Check only aggregated that failure.
So what: The planner reviews the new exact head and its fresh CI, then owns any approved rollout; no installs or restarts were performed in this follow-up.

Current PR body with complete commands, failure logs and comparisons.

One rebase conflict: scripts/fork-upstream-edits.txt. Retained both main's secret/OAuth/research additions and #541's paths. Range-diff: 749e3369e1 -> 4be08dfb65 differs only in allowlist context; 0727249d45 -> 2265c34feb is identical; 2a511fa8e9 adds the fixture repair and fork metadata. No merges or version bump.

Read both failing jobs: Test 118154631974 reports [UNRESOLVED_ENTRY] Cannot resolve entry module src/preview/BrowserImport/ChromiumKeychainWorker.ts; aggregate Check 118158145217 reports test: failure. The fixture now derives worker entries from the actual build configuration, creates nested worker paths and uses the correct relative shared import. Every worker still executes in the bundle harness and the final desktop-startup count must stay exactly one.

Comparison: rebased candidate before repair reproduces 1 failure / 1 pass; the byte-identical test and config from current main pass 2/2, and main CI run 39334964453 is green. Corrected fixture: 2/2 PASS. This is our PR regression, not a pre-existing main defect.

Final-source commands/results:

• Focused vp test run selection in the PR, now including apps/desktop/scripts/main-process-bundle.test.mjs: 21 files / 192 tests PASS.
• vp run --filter @t3tools/desktop typecheck: PASS, five existing suggestions.
• vp lint on all 10 changed JS/TS files: PASS.
• vp fmt --check on all 15 supported touched files: PASS.
• vp run knip:check: both phases PASS, 0/2 cache hit; no dependency declarations changed.
• (cd apps/desktop && vp pack): PASS, existing optional x11/import-meta warnings only.
• scripts/fork-check.sh, node scripts/fork-features.mjs check, git diff --check: PASS.

Explicit lease was against remote 0727249d45c20bcb044b80054c835390d2aae7c1. The old Opus review status does not cover this new exact SHA. Fresh review/CI, native Rocky acceptance and rollout remain planner-owned. Existing cached dependencies were reused with an explicit Electron path; no installer, app launch/restart, dev server or live Keychain/cookie read was used. Keep this task worktree for review and retirement at merge.

Requirements and who asked: Planner: rebase, fix both failing checks, preserve worker/startup isolation, rerun focused gates and vp pack, and push with a lease.
Deleted: Stale fixture inventory, treating a production bundle pass as synthetic bundle-test proof, and a separate patch for the aggregate Check job.
Bottleneck: Fixture compilation failed before reaching its desktop-startup isolation assertions.
Checked myself: Both failed logs, red/main/green bundle comparison, 192 focused tests, real bundle output, all scoped checks, full Knip, range-diff, fork ownership and lease target.

Independent review at 2a511fa8e9 (rebased on 1e83a31): PASS (Claude Opus 5.5). Fresh review; the 0727249d45 PASS was not reused.

• Nothing under apps/desktop changed between e5936c2 and 1e83a31; the diff is the previous candidate plus the bundle-fixture repair.
• scripts/fork-upstream-edits.txt conflict: additive only, main's entries kept, four fix(desktop): Chrome login mirror hangs startup on Macs that are not the source #541 paths appended.
• Bundle test oracle: making the Keychain worker fixture import src/main.ts fails with expected [ 42, 42 ] to deeply equal [ 42 ].
• vp pack emits dist-electron/preview/BrowserImport/ChromiumKeychainWorker.cjs at the path main.cjs resolves; main.cjs has no @napi-rs/keyring reference.
• Chrome source only with a nonempty key command (DesktopCookieMirror.ts:174); the only native read is in the worker (ChromiumKeys.ts:72-107).
• 15 files / 138 focused tests pass.

Unproven: native signed-app worker load; the Rocky live run settles it.
