What’s in this sync

Adds 174 upstream commits beyond parent PR 520, including preparation for v0.1.6.

• Features: pin favorite projects and archive old ones (pingdotgg/t3code#26154); schedule a task once at a specific date and time (pingdotgg/t3code#28104); open a dev-server port directly through preview_open and bulk link/unlink PRs through MCP.
• Fixes: more reliable Working states, scheduled-task interruption and default branches, queued messages and model selection, remote folder updates, mobile scroll/attachments/accessibility, desktop startup and SnapShots, and RTL text across clients.
• Provider and performance changes: Claude stop acknowledgement handling; Codex request write failures; Cursor tool completion and stale login handling; Copilot plan/session recovery; OpenCode startup limits and Big Pickle defaults. Reduced sidebar/side-chat renders, remote file latency, startup discovery, and unnecessary orchestration history reads.

Discord announcements were not used: the channel returned only older non-crosspost messages, with no announcements matching this range.

Remaining changes include RTL and accessibility fixes, GitLab/SSH authentication handling, theme import robustness, source-diff generation, command palette PR status, device tooling, documentation, and script/CI maintenance. Notable references: pingdotgg/t3code#24050, pingdotgg/t3code#25375, pingdotgg/t3code#22503, and pingdotgg/t3code#23156.

Conflict resolutions

Preserved fork sidebar filters, chat tabs, integration chips, account pickers and provider support while incorporating project pin/archive behavior, upstream status fixes and one-time schedules. Retained scheduler catch-up and self-wait guards, provider credential/quota behavior, environment capabilities and importer message counts. Adapted clean-merge consumers for once schedules, secondary trait labels and thread refresh. Updated fork-differences sidebar guidance. No conflicted upstream file split was found in this range.

Verification

• vp i completed; local Vite+ 1.4.0 used (global executable was outdated).
• Final vp run check:changed 7bab9ace54e7314a6807fa7c4b368901bd5ce2ed passed: formatting, lint, both Knip checks, dependency patches, GraphQL generation checks, 39 affected package typechecks, 258 test suites, and React Compiler checks across 163 files.
• Focused conflict tests and affected package typechecks passed; git diff --check passed. Initial integrated failures were resolved and the full changed-file check rerun successfully. Local Electron binary installed to run its dependent suite.
• MCP model eval attempted but unavailable: local Codex config lacks model_providers.vibeproxy. Interactive local-web verification was subsequently authorized and completed; see below.
• Earlier runs already linked sync PRs; none required takeover or superseding.

Merge with Create a merge commit. It keeps upstream history and the merge base for the next sync.

Model/harness: gpt-6.1-sol through Codex in T3 Code.

Interactive regression verification

Completed a local web pass against this worktree's isolated .t3 state through T3's Browser panel. No code changes were needed.

• Free Replay (dev) showcase streamed thinking/tool activity, reached approval, continued after approval, rendered its final markdown/code/table, and left Working.
• Fork sidebar Show/Organisations/Projects menus opened; project filtering produced a removable project pill and survived navigation.
• Model picker opened with replay scenarios and permission controls.
• Created a chat tab: parent context and the two-tab group remained available; navigated back to the completed parent.
• Created a disabled one-time scheduled task; reloaded and reopened it, preserving date/time and paused state. Changed it to fixed-time with Catch up missed run, saved and reopened: catch-up remained true and enabled remained false.

Initial preview_status returned available:false because this thread had no browser tab, not because browser automation was unsupported. That earlier blocker interpretation was incorrect; a tab is now available and verification proceeded.

Limits: local web only. Native Electron behaviors, native mobile, remote/tunnel modes, connected third-party integrations and real-provider turns were not exercised. Scheduler execution itself remains covered by automated tests; the interactive fixture stayed disabled. One panel click timed out; keyboard interactions and DOM clicks through preview_evaluate completed the flows. No alternate automation system was used.

Native desktop verification

Tested Electron 44.10.0 / macOS arm64 from merge e2d898a, using this worktree's isolated .t3 and the desktop skill's in-process hook. No real provider turn sent; no code change needed.

Passed:

• Desktop dev build/startup, backend startup/authentication and rendered local project/thread state.
• Quick message Alt+/ registered; invoking its registered callback opened a separate BrowserWindow, focused the textarea, and left main window separate. This tests callback behavior, not physical OS shortcut delivery.
• Unsent draft remained after Escape dismissal and reopening. Cleared the test draft afterward.
• Project picker and model picker opened through Electron sendInputEvent pointer input; model list included Codex options and Show more.
• Native macOS application menu exposed settings, Paste as Text CmdOrCtrl+Shift+V, window and zoom actions. Invoked Zoom In callback and observed renderer zoom change, then restored original factors (zoom shared across same-origin windows).
• Captured and visually inspected the floating panel with capturePage.

Limits/observations:

• Dev rebuilds restarted Electron during initial checks; repeated after rebuild settled. Focus loss hides the quick panel, so focus-sensitive checks across calls were inconclusive and not treated as product failures.
• Native resource telemetry warned that its darwin/arm64 binary was missing; not verified.
• Not exercised: physical OS shortcut delivery, clipboard paste contents, native file dialogs, SnapShots/OS capture permissions, webview CDP host-focus restoration, deliberate slow-backend startup, Windows/Linux native behavior. Existing automated checks cover related protocol logic.
• No paid turn, release, or merge. Screenshots kept local because this run prohibits publishing releases.

Teardown: hid windows, cleared draft, restored exact client-settings.json prior state, stopped only recorded tree (stop.log: Still alive none), and verified ports 47999/8414/16454 free. Git working tree clean.
