🟠 High handoff/ThreadHandoff.ts:170
remoteProject can report no matching project or select a supposedly unique match when the correct inventory contains additional projects, so options and start choose the wrong destination result. The t3_project_list call requests only 100 projects, and this code counts matches without following listed.nextCursor; fetch all pages before deciding whether the match count is zero, one, or ambiguous.

A queued run can remain unstarted indefinitely after a pending handoff is cleared. If the terminal-run worker reaches startNextQueuedRun first, this guard skips promotion; ThreadHandoff.settle then clears the handoff by emitting only thread.metadata-updated, which does not trigger queue promotion.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR introduces a substantial cross-environment thread-migration workflow with Git/worktree mutation, remote upload/import, persistent orchestration state, and changes to existing turn and queue behavior. It also modifies authorization code and has unresolved correctness and data-integrity concerns around retries, cleanup, races, and duplicate live copies. Not approved because:

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Move the moved-thread guard into dispatchMessage.
The guard runs only for top-level message.dispatch commands. Some paths call dispatchMessage directly and skip it:
dispatchPullRequestWatchSync(the PR watch wake).- The async-answer path of
dispatchRuntimeRequestRespond.
Nothing in the move ends the thread's PR watches. Consider a departed thread that still has a watch. The next watch sync dispatches a queue_after_active message. No run is active, so the message starts a turn here. The thread is then live in two environments, which breaks the "exactly one copy live" invariant.
Do one of the following:
- Put the
departing/departedcheck at the top ofdispatchMessage. - Make the
departingtransition end the thread's PR watches, asthread.archivedoes.
Proposed fix
- // A thread moving away, or gone, takes no new turns here.
- if (thread.handoff?.state === "departing" || thread.handoff?.state === "departed") {
- return yield* new OrchestratorThreadMovedError({
- commandId: command.commandId,
- threadId: command.threadId,
- label: thread.handoff.label,
- state: thread.handoff.state,
- });

Make undo also undo the branch change, as the doc comment says.
The doc comment says the worktree and branch are undone if the import fails. undo only runs git worktree remove --force.
HandoffGit.apply can create refs/heads/<branch> or fast-forward an existing branch. If the thread write fails afterwards, the branch stays created or advanced on the destination.
Do one of the following:
- Have
applyreturn its rollback effect, and use that effect asundo. - Correct the doc comment.

Do not mark the move failed when the import may have succeeded.
forwarding.call(t3_thread_import) can import the thread and start its continuation on the destination, and the response can then be lost (timeout or connection drop).
In that case this code marks the source failed, and the source takes turns again. The destination copy is also running. Two copies are live.
A new start generates a new handoffId, so the import idempotency key does not protect this case.
When the failure is a transport or ambiguous error, keep the thread departing. A later settle or the restart pass can then retry with the same handoffId, which the destination replays. Mark failed only on errors that are certain to have rejected the import, such as invalid_request or a pack failure.

Update the `result._tag === "Failure"` handling in `ThreadHandoff` to
distinguish definite import rejections from transport or ambiguous failures.
Mark the handoff `failed` only for certain rejection errors such as
`invalid_request` or pack failures; otherwise keep it `departing` so retry and
replay use the existing `handoffId`.

Settle the move once after writing pending.
busy is read before the lock. The turn can end between that read and the pending write.
If its terminal run.updated event reaches settle first, settle sees no handoff and returns. The move then stays pending until another run ends or the server restarts. During that time startNextQueuedRun blocks the queue.
Call settle(input.threadId) right after setHandoff. settle is idempotent and returns while the turn is still live.

Start the queue after a move is cancelled.
startNextQueuedRun (Orchestrator.ts Line 1274) returns early while the handoff is pending.
Consider a user who queues a message during the asking turn:
- The turn ends.
handleTerminalRuncallsstartNextQueuedRun, which returns without starting the queued run.settlethen clears the handoff here.
Nothing calls startNextQueuedRun again, so the queued message waits until the next restart. Whether this happens depends on which of the two listeners runs first.
After a thread.handoff.update commit that clears or fails the handoff, call startNextQueuedRun in dispatchWithReceiptEffect (Orchestrator.ts), as queue.resume does.
Proposed fix (Orchestrator.ts, after commit)
if (
command.type === "thread.handoff.update" &&
(command.handoff === null || command.handoff.state === "failed")

Update `dispatchWithReceiptEffect` in `Orchestrator.ts` to call
`startNextQueuedRun` after a `thread.handoff.update` commit clears the handoff
or sets its state to failed, propagating dispatch errors through the existing

Bound the startup event subscription.
start_ scans the snapshot, then subscribes to threads.streamStoredEvents. Orchestrator.ts documents that this stream replays the entire store from genesis. The downstream filter still decodes every event, and settle can read projections for every historical terminal run.
Capture the global latest sequence before the snapshot scan, then use threads.streamStoredEventsFrom({ afterSequence: latest, eventType: "run.updated" }). Expose the global sequence through ThreadManagementService if needed. Do not use getThreadEventSequence(threadId) for this subscription because it is scoped to one thread. Keep the terminal-status filter.

Add the supported handoff options to the start RPC payload.
ThreadHandoff.start accepts whenTurnEnds and continuationPrompt, but this payload declares neither field. A typed WebSocket client cannot request a handoff after an active turn or supply a continuation prompt. Add both optional fields to the schema. The handler already forwards the input.

Effect TypeScript DateTime makeUnsafe invalid string throws official documentation
💡 Result:
Yes. In the current official Effect `DateTime` source, `DateTime.makeUnsafe` is for trusted input: it accepts strings parseable by `Date.parse` and throws an `IllegalArgumentError` if construction fails. For untrusted strings, use `DateTime.make`, which returns `Option.none` for an unparseable string instead of throwing. ([github.com](https://github.com/Effect-TS/effect/blob/main/packages/effect/src/DateTime.ts))

Cover event construction with worktree cleanup.
createdAt accepts any string, and DateTime.makeUnsafe can throw while historyEvents is built, before EventSink.write starts. The current tapError cannot run in that path, so the applied worktree can remain without an imported thread.
Cover the full post-workspace creation path with cleanup, including event construction, and use fallible date validation or typed error handling. A startContinuation failure occurs after the thread event is committed and is not this orphaned-worktree path.

Include the expected handoff ID in the compare-and-set check so transitions for a cancelled move cannot affect its replacement.

A thread can now move to a linked environment with its conversation and its git work, with exactly one copy live. ThreadHandoff marks it departing, which refuses new turns and keeps queued runs from starting; packs the branch and working tree with HandoffGit; uploads the bundle through the other side's signed attachment route; and calls t3_thread_import there, which now takes the bundle and applies it in a new worktree before creating the thread. Only then is the thread departed here and read-only. A failed move marks it failed, which takes turns again, and nothing is left there. An agent can move its own thread with t3_thread_handoff. The move then waits as pending until its turn ends, starts the thread there with the agent's continuationPrompt, and is cancelled by a user message sent before the turn ends. A startup sweep runs moves that a restart cut short; import ids derive from the handoff, so a retry finds the thread already there. threadHandoff.options / start / cancel serve the clients.

Part of cross-environment orchestration. A thread can now move to a linked environment with its conversation (#16731) and its git work (#16734), with exactly one copy live.
How a move goes
ThreadHandoffmarks the threaddepartingwith the internalthread.handoff.updatecommand. The orchestrator refusesmessage.dispatchfor it, andstartNextQueuedRunstarts nothing on it.HandoffGit.t3_attachment_prepare_uploadplus a POST.t3_thread_importthere. That tool now takes the bundle, applies it in a new worktree, and only then creates the thread with the history and a continuation prompt. If the import itself fails, the worktree is removed.departedand read-only, with the other thread's id. A send is refused withOrchestratorThreadMovedError("This thread moved to Box. Continue it there.").failedwith the reason. That state takes turns again, and nothing is left on the other side.The agent moving its own thread ("I need to wrap here, move this to my VPS")
t3_thread_handoffwith nothreadIdmoves the calling thread. The link and the target project are checked right away, so a bad target fails while the agent can still say so.pendinguntil the agent's turn ends. Then the thread there starts with the agent'scontinuationPrompt, so it picks up where it said it would.Surfaces

peer/handoff/ThreadHandoff.test.tsruns two real orchestrators. The box sits behind its real/mcp, OAuth and upload route; the laptop is linked to it. Each has a real clone of the same origin. Three tests:optionslists the box with its matching project. On the box, the thread has the history, its first provider turn carries the laptop's question plus the continuation, and its worktree is onfix/loginwith the commit, the edit and the file.
