Sync T3 Code upstream through 6a6ebb278dc70dd859439a3c28960a7d23a1e645 (409 upstream commits) while keeping upstream ancestry and the Workbench overlay. Replaces closed #144. Merge with a merge commit (gh pr merge --merge), not squash.

Changes

Merge (d89c335)

• Resolved 24 conflicts, all in apps/web plus pnpm-lock.yaml. Each resolution keeps upstream behavior and reapplies the existing Workbench integration:
  • ChatView: kept upstream's extracted right panel, which moved the fork's panel integration into RightPanelSurfaceContent and useProactivePanels.
  • PR panels and dialog: kept PR browsing, number search and URL acceptance, focused review threads, and remote-checkout safeguards.
  • Sidebar and command palette: kept visible-Thread filtering, Workbench execution status, and host utility pages.
  • Update paths: kept Workbench release links and the npm-update restriction.
  • Upstream test migration: upstream moved several unit tests to browser suites. Fork regression cases moved into the new browser suites.
• Regenerated pnpm-lock.yaml with vp i instead of merging it by hand.
• Left out upstream e58a485 (native iOS segmented controls), as chore: sync T3 Code upstream #144 did. iOS keeps the shared control with option-specific spoken labels, selection state and tab roles. Upstream's native wrapper still passes neither. The follow-up 79ad856 touches only the removed implementation.
• Advanced the CI ownership baseline to the pinned upstream SHA.

Follow-up repairs (292e4ae)

• Added CI ownership entries for the extracted RightPanelSurfaceContent and useProactivePanels integrations and for the retained mobile controls and PR actions. Added mobile typecheck routing and the rerun-failed-checks label and icon entries.
• Install Chromium before the integration job's browser tests and the sync workflow's integration tests.
• Kept the web test dependencies that fork tests still use. Pointed fork mocks at upstream's new atom config owner.
• Did not port chore: sync T3 Code upstream #144's workbench-upstream-sync-merge.ts changes. ci(workbench): make upstream sync publish reliably and gate fully #145 already covers merge-ref readiness and dispatch recovery.

Verification

• vp run --filter @t3tools/workbench typecheck (including the package boundary), plus the web, server (t3) and mobile typechecks, passed.
• vp run --filter @t3tools/desktop smoke-test passed.
• Six conflicted browser suites passed: 217 tests.
• 21 focused conflict and unit suites passed: 559 tests.
• The CI, sync and isolation suites passed: scripts/workbench-ci.test.ts, workbench-upstream-sync*.test.ts and scripts/lib/workbench-isolation.test.ts.
• node scripts/workbench-ci.ts --check and node scripts/workbench-isolation.ts passed at 292e4ae.
• The only files that now differ from upstream without a prior fork change are the planned exclusions above, the migrated browser tests, and the two extracted integration points. The format hook rewrote no upstream file.
• Confirm after merge: git merge-base --is-ancestor 6a6ebb278dc70dd859439a3c28960a7d23a1e645 origin/main.

Limits

• No live client pass yet. A demo spot check follows the merge.

@codex review

Please review exact head b6a08d7f68a1be553fb4dbc1f0f903e55ed6d562 against base 01cc135c82eebe430a3d099b845995f9cd7579be for the daily upstream compatibility review. The prior automatic review predates the follow-up repairs.

Independent native/state, client and CI/distribution audits found no confirmed defects in their inspected Workbench boundaries. The cloud review passed 277 focused compatibility tests plus 49 migration, composition, sync and isolation tests, Workbench/contracts typechecks and the package/host import gates. This is review-only; no merge, release or upstream-sync workflow dispatch is authorized.

Since the prior reviewed head, the owner restored the Mac platform fixture for the migrated PR-number shortcut test. At the user's request, the one-line desktop smoke routing fix is now included directly in this PR: chore/upstream-sync-* branches run the existing smoke job. The existing event guard and prior branch alternatives remain intact. Independent review and Test Audit found no issues in these two focused changes. Please keep this review read-only; no merge, release or upstream-sync publisher dispatch.

@codex review

Please review exact head 8dce60e69c00d88d48c2ca03779d4b7ae07a80e6 against base 01cc135c82eebe430a3d099b845995f9cd7579be.

Since the prior reviewed head, this adds only a test synchronization repair in ChatMarkdown.browser.test.tsx. After the existing animation-frame wait, the same exact highlight-text assertion now uses vi.waitFor and rereads the current highlight registry each attempt. All table cases and the separate indexed-occurrence assertion remain intact. No production code changed.

The baseline integration run failed the Mermaid case with an empty live Range. Independent Test Audit found no weakened assertions or new seams. Seventeen focused search/indexing tests, targeted formatting, the generated CI check and Workbench host boundary passed locally; corrected Chromium execution is pending hosted CI.

Keep this review read-only. This significant upstream sync returns for user review; do not merge or dispatch releases.
