The review item is correct. WorktreeBranchSync checked activeRunId, then awaited the project, realPath and git.currentBranch reads before it dispatched. expectedBranch/expectedWorktreePath cannot detect a run that started in that gap. The orchestrator accepted the worktree change and queued provider-session.detach, ending the new turn. Fix: thread.metadata.update gains an optional expectedIdle flag (contracts). With it set, the Orchestrator rejects the update when any run is preparing, starting, running or waiting (CommandPolicy.isActiveRun). The check sits beside the existing expectedEmpty check, so it runs within the decider's per-thread serialization and closes the race. WorktreeBranchSync sets expectedIdle: true. A rejected update is logged and retried when that run ends, through the existing run.updated trigger. Other callers are unaffected, including the T3 worktree handoff, which detaches its running session on purpose. The original fix is unchanged: Claude's EnterWorktree/ExitWorktree hook records the move on the provider session, and WorktreeBranchSync applies it to the thread once idle. No new regex or parser.

Fixes #11078

Reproduction on main

Commit f03db4f (origin/main). Scratch git repo: main checkout on branch fix/preview-uri-expiry-retry, plus a linked worktree at .claude/worktrees/home-screen-design on branch home-screen-design. Started the web app with T3CODE_DEV_SEED=0 vp run dev (fresh database) and added the repo with t3 project add. Ran t3 thread start --provider claudeAgent --model <cheapest Haiku> --wait <repo> "Use the EnterWorktree tool with path <repo>/.claude/worktrees/home-screen-design ... then run pwd && git branch --show-current". The agent's EnterWorktree tool result was 'Entered worktree at on branch home-screen-design. The session is now working in the worktree.' The agent printed the worktree path and home-screen-design. After the turn, the thread projection still held "branch":"fix/preview-uri-expiry-retry","worktreePath":null. In the browser, the sidebar row showed fix/preview-uri-expiry-retry, and the thread details panel showed the branch picker on fix/preview-uri-expiry-retry with 'Changes vs main' computed for the main checkout, not the worktree.

Evidence

Ran both commits as separate real web apps with fresh unseeded databases, identical synthetic repositories, Chromium at 1280×800, and light theme. Recorded the same live Claude instruction: EnterWorktree into .claude/worktrees/home-screen-design, then run pwd && git branch --show-current.

Both runs successfully entered home-screen-design. Base kept the old branch and null worktreePath. Head updated the sidebar, branch picker, worktree indicator and worktreePath; Changes vs main reflected the clean worktree. Machine and model labels are masked.

Not shown:

• PR badge behavior was not exercised because the synthetic repository had no remote or linked pull request; file previews were not opened.
• ExitWorktree, ordinary branch checkout, and a follow-up turn racing the metadata update were not exercised by this reproduction.
• Desktop shell and mobile clients were not exercised; captures cover the web client.

Tests

vp test run src/orchestration-v2/WorktreeBranchSync.test.ts src/orchestration-v2/runtimeLayer.test.ts -t "worktree move|rejects settling a thread while a run is active": 5 passed. With the Orchestrator.ts change stashed, the extended runtimeLayer case fails (1 failed), and it passes once restored. vp run check:changed: format, lint, knip and typecheck pass, 608 tests in 8 files pass.

Not in this change

• Following moves by providers without a native worktree hook (Codex, OpenCode and others using git worktree add plus cd), for example by matching command cwds or changed paths at turn end.
• Updating the location mid-turn, so file previews and status are right before the turn ends.
• Not claiming a branch for a thread whose new worktree another thread already uses (triage's shared-worktree guard). Today those threads get the same label, as the existing WorktreeBranchSync already does.
• Keeping a project's selected repository subfolder when following into a worktree: the thread points at the worktree root.
• An orchestrator-side guard that rejects a worktree change racing a just-started run. The window between the idle read and the dispatch is small but not closed.
• In-place branch switches in a thread that has no worktreePath (main checkout), reported in a later issue comment.
• Following moves by providers without a native worktree hook (Codex, OpenCode and others).
• Updating the location mid-turn rather than after the turn ends.
• Not claiming a branch for a thread whose new worktree another thread already uses; this matches the existing WorktreeBranchSync behavior.
• Keeping a project's selected repository subfolder when following into a worktree.

Approvability

Verdict: Approved at 4f9d8ce

Macroscope's review found this PR approvable — Threads now follow Claude’s native worktree changes after the run becomes idle. Source-checkout and stale-state guards limit interference with active runs or later checkout changes.

Walkthrough

Claude worktree moves now update the live provider session and can reconcile a thread’s worktree path and branch. Metadata updates can require an idle thread. Caller-provided Claude hooks are preserved when the device SubagentStart hook is added.

Changes: Provider-session worktree reconciliation

Layer / File(s)	Summary
Session and metadata update contracts packages/contracts/src/orchestrationV2.ts	The provider-session contract adds optional cwdChangeSource. Thread metadata updates add optional expectedIdle.
Claude worktree move tracking apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts	Claude query options preserve caller hooks when adding the device hook. Root-session worktree hooks update the live session cwd and emit provider-session updates. The runtime exposes the live session.
Guarded thread worktree reconciliation apps/server/src/orchestration-v2/WorktreeBranchSync.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/runtimeLayer.ts, apps/server/src/orchestration-v2/WorktreeBranchSync.test.ts, apps/server/src/orchestration-v2/runtimeLayer.test.ts	Eligible session moves update thread worktree metadata with expected branch, path, and idle-state checks. The orchestrator rejects expectedIdle updates while a run is active. Wiring and tests cover moves, rejected updates, and ineligible sessions.

Merge Risk: Low · up to 4f9d8

Claude worktree moves now update the thread's branch and worktree path once the thread is idle. A latent hook-overwrite edge case and a missing adapter-level test for the new hook remain. Neither blocks the feature today, and both are cheap to fix before or shortly after merge.

Full details: Title check

Explanation

The title names the main change: a thread now follows Claude's EnterWorktree and ExitWorktree moves. It also uses the conventional commit form. The changeset records these native worktree moves on the provider session and updates the thread's branch and worktree path once idle, which matches the title. The title does not mention the expectedIdle guard, but it does not need to cover every detail.

Full details: Linked Issues check

Explanation

Directly linked issue #11078 asks that the sidebar thread row stop showing the creation-time branch after the session moves to another worktree and branch. The PR addresses this for Claude native worktree moves. ClaudeAdapterV2 tracks the root-thread cwd changed by EnterWorktree and ExitWorktree hooks. WorktreeBranchSync reads that move from the provider session and updates thread.worktreePath and thread.branch once the thread is idle. The new expectedIdle guard in Orchestrator.ts (thread.metadata.update) rejects the update while a run is preparing, starting, running, or waiting, which closes the race that the PR describes. Tests in WorktreeBranchSync.test.ts cover moving from the root into a worktree and back. runtimeLayer.test.ts covers the rejection while a run is starting. The issue's stale linked-MR badge is not addressed directly. The issue says the badge is resolved from the same stamped branch, so it should follow the corrected thread.branch, but the PR does not test that path. The PR's stated exclusions (providers without a native hook, mid-turn updates, in-place switches on main checkout threads) fall outside the issue's reproduction, which uses Claude EnterWorktree. The 'Evidence' section of the PR description is still empty. This is a process item, not a coding requirement.

Full details: Out of Scope Changes check

Explanation

Each changed area connects to the objective of following Claude native worktree moves. ClaudeAdapterV2.ts adds caller hook merging and root-thread cwd tracking, which supplies the move signal. Orchestrator.ts adds the expectedIdle guard, and contracts/orchestrationV2.ts adds the matching optional field and cwdChangeSource. WorktreeBranchSync.ts adds the move handler and its triggers. runtimeLayer.ts passes ProjectService to WorktreeBranchSync so the handler can resolve paths. The tests cover these changes. No unrelated change was identified in the summary. The PR description repeats several exclusion bullets, which is a documentation issue only.

Full details: Description check

Explanation

The description is thorough and largely follows the template. It explains the problem (WorktreeBranchSync reads the project, realPath and branch after its active-run check, so a run that starts in that gap is not detected), the change (the expectedIdle guard on thread.metadata.update, enforced in the Orchestrator beside expectedEmpty), and the scope (it links the fixed issue, #11078, and the linked PR #35471). Verification is detailed: a before/after reproduction on main, screenshots and recordings, a targeted test command with results, and a list of checks not performed. The description lists the model and harness in its AI-assisted note, but the template asks for the model and harness at the end, and it does not name the model. The Not in this change section repeats several items (provider coverage, mid-turn updates, shared-worktree behavior, subfolder handling) and has a duplicated block. These are cosmetic issues and do not block merge.

Preserve caller SubagentStart hooks.

Minor · Maintainability & Code Quality · Quick win

Add adapter-level coverage for the worktree move hook.

No test under apps/server/src references PostToolUse, EnterWorktree, or ExitWorktree. The reconciliation tests in WorktreeBranchSync.test.ts start from a session that has already moved. They do not run the hook that records the move. A regression in the hook's cwd update or its subagent exclusion would not fail any test.

Add a case that invokes the installed PostToolUse hook through the fake query runner. Assert the emitted provider_session.updated cwd and cwdChangeSource. Add a second case for a subagent EnterWorktree that must not move the root session. Put these rows in an existing table in ClaudeAdapterV2.test.ts if one fits. Otherwise add a new it case.
