What's in this sync

New features

• Claude idle compaction gets a global default and per-instance overrides (pingdotgg/t3code#23037); full-access approvals explain why Claude asked (pingdotgg/t3code#22546). Automation messages use compact timeline rows (pingdotgg/t3code#22638).
• ChatGPT Business usage limits offer a copyable request for an admin (pingdotgg/t3code#23361). GitCafe pull requests support reviewer requests and labels (pingdotgg/t3code#23034).
• Webhook filters can match array entries with [] (pingdotgg/t3code#23282); run telemetry exports duration and outcome (pingdotgg/t3code#22094).

Fixes users will notice

• Mobile unifies draft/thread navigation and composer behavior, preserves drafts and long-draft scroll positions, fixes iPad headers/composer alignment, and improves iPhone Duo folding, safe areas, search, sheets, and scroll retention. It also fixes pull-request opening crashes (pingdotgg/t3code#23467, pingdotgg/t3code#23366, pingdotgg/t3code#23096, pingdotgg/t3code#23149, pingdotgg/t3code#22600).
• Web avoids broad rerenders while streaming or typing, bounds list layout passes, supports right-to-left Arabic/Hebrew text, and fixes paused video reloads. Composer prices no longer open the skill menu, special-character filenames remain chips, and panel/Usage/undo-settle shortcuts behave correctly (pingdotgg/t3code#23117, pingdotgg/t3code#23124, pingdotgg/t3code#22730, pingdotgg/t3code#23315, pingdotgg/t3code#22777, pingdotgg/t3code#21519, pingdotgg/t3code#22922).
• Git operations retry refused SSH clones over HTTPS, refresh refs after reconnects, report refused pushes, retain PR diff files on unchanged refreshes, sync draft status, and fix Forgejo/GitCafe linking, GitLab pagination, Azure DevOps names with spaces, and copy-to-machine fork selection.
• Servers stop abandoned runs before continuing, stop Claude children when their owning server dies, prune obsolete SSH runtimes, and safely remove Windows worktree junctions. Network file paths outside a thread's project are blocked across markdown assets, file reads, metadata, and cleanup (upstream commit a12d6ed942). Older clients connect again after idle-compaction setting changes (pingdotgg/t3code#23454).

Provider and internal changes

• Agents get a compact current model catalog; Claude delegated children follow cache TTL settings, Codex retains all paths in multi-file patches, Antigravity retains question options, Pi can fork completed turns during a running turn, OpenCode distinguishes out-of-funds errors and cancelled todos, and Cursor closed-stream writes no longer crash the server.
• ChatView, composer, and settings logic moves into focused hooks/components. Development and standalone builds pin Node 26.12.1, and TypeScript uses the tsc-rs drop-in without the Effect patch.

Remaining commits cover file links and theme fixes, update/sign-in diagnostics, queue handling, scheduled-task ordering, telemetry/test fixtures, development performance and changed-file check tooling, release deployment fixes, and corrected user/contributor guidance. The full commit list below records every included change.

Merge scope

Base: main at a566bcc117e4741b9463e23497c98588522eb360. No open upstream-sync PRs existed at selection or refresh. Main advanced during preparation; the merge was redone from that exact new head.
Pinned upstream: 8d3b061121fe65669d5d43d011b48cd3027a4108.
Range: a566bcc117e4741b9463e23497c98588522eb360..8d3b061121fe65669d5d43d011b48cd3027a4108 (153 upstream commits; 503 fork-only commits before merging).

Conflict resolutions

• Web: adopted upstream's extracted ChatView/composer/settings hooks while keeping fork chat tabs and split panes, context integrations, account/model switches, citations, server drafts, empty-thread creation, usage recovery, agent controls, scheduled-task shortcuts, and terminal settings. Kept both sides' tests and combined terminal ANSI imports with theme readability changes.
• Mobile: retained chat tabs, grouped/hidden selection and filter facets, usage notices, Conductor controls, integration pickers, send menus, and queue labels within upstream's shared draft/thread navigation and toolbar structure. Review caught and repaired synthetic-draft subscriptions and premature server-draft actions; repository context still preserves new-worktree creation.
• Server/contracts/providers: retained fork delegation/workspace guidance and options, usage-limit recovery/guards, rollback contracts, Claude cwd behavior, settings migration, Cursor Max Mode tests, and composer helpers. Codex keeps fork unified multi-file diffs/model attribution alongside upstream per-file metadata. Kept both sides of add/add tests and fixed MCP middleware typing.
• Shared fork-point helpers now accept upstream's quiet structural turn items without discarding native fork points. Updated fork-differences source pointers and reconciled the usage guide's enabled environments with fork service-status guidance.
• On the refreshed base, the verified resolved tree is byte-for-byte unchanged except for main's newly merged database-seeding fix. The upstream commit list is identical. No existing sync branch was modified.

Verification

Used repository-local Vite+ 1.3.0 after vp i; global Vite+ 0.3.1 cannot load this checkout's task configuration.

• Web: typecheck passed; 819 unit tests across 18 files passed; focused lint/format passed with existing warnings.
• Mobile: typecheck passed; 243 focused tests across 19 files passed; after review repairs another 101 focused tests passed; lint/format passed with warnings. The broader mobile unit run had 2,260 passes and 14 baseline failures: 13 compiler-coverage failures reproduced against original fork HEAD, plus an unchanged provider-badge fixture missing settings.threadGroups.
• Server/shared/contracts/Cursor: typechecks passed; 757 focused tests across 13 files passed, with strengthened Codex and agent-access checks rerun successfully; focused lint passed with warnings. Independent server review found no actionable merge regressions.
• Client-runtime: typecheck passed; 56 tests across five files passed. Structural fork-point change: 11 tests and contracts/client-runtime typechecks/lint passed.
• Refreshed-base database seeding: 7 tests passed; targeted lint passed. Independent web review found no actionable merge regressions and confirmed identical web source after the redo.
• Scoped knip was run. It reports existing unused sidebar files and unused exports; the three sidebar files were confirmed disconnected in the original fork source. This is not a clean knip result.
• git diff --check passes excluding the unchanged upstream Reanimated patch, whose blank patch-context line triggers trailing-whitespace detection. The upstream patch is preserved.
• check:changed was inspected but not run: it unconditionally selects browser tests and repository-wide knip, conflicting with this run's explicit restrictions. Focused checks above cover the resolved areas. No browser/computer automation or dev server was launched.
