Stacked on #11762, which adds the server-side background clone. This layer brings mobile onto it.

Mobile used the blocking sourceControl.cloneRepository call and only opened the draft once git returned, so a large repository meant a spinner on the Add Project destination screen for minutes.

How it works now

On servers that advertise projectCloneTracking, the destination screen calls projectClone.start and opens the New Task draft immediately. Older servers keep the blocking path.
The draft shows a banner above the composer with live progress (stage, percent, transfer rate) and Cancel while the clone runs. Start is disabled until the clone lands; the reason is in its accessibility label ("Cloning repository" / "Repository not cloned"), and the prompt can be typed meanwhile.
A failed or cancelled clone shows the error git reported with Retry and Remove project. Remove is a non-forced delete and returns to Home.
state/projectClones.ts mirrors the web atom and is gated on the capability, so old servers are never subscribed.

Before / after

iPhone 17 Pro simulator, same local fixture repository and a disposable server on each branch.

Before (#11762 only)	After
Add Project destination screen is stuck on a spinner until git finishes	Draft opens immediately with the cloning banner; Start disabled ("Cloning repository")
before: destination screen blocked with a spinner while cloning	after: draft with Cloning banner, Cancel, and disabled Start

After: failed clone	After: clone finished
Git's error, with Remove project and Retry	Banner gone, branch resolved to `main`, composer usable
after: failed clone banner with Remove project and Retry	after: clone finished, banner gone, branch main

The "cloning" capture shows 100% checkout because the fixture clones in about a second; a slow post-checkout hook held git open so the running state could be captured. The banner sits above the "Current checkout / branch" row so those controls stay anchored to the composer when it disappears.

Verification

Mobile typecheck, lint, and knip pass. The server behavior (guard, tracker, stream) is covered by the tests in #11762.
Manual pass on the simulator for the running, failed (with Remove project), and finished states shown above.

🟡 Medium threads/NewTaskDraftScreen.tsx:237

removeClonedProject always dispatches StackActions.replace("Home") when deletion resolves, so selecting another project while the deletion is in flight still ejects the user to Home even though that project was not removed. Disable project switching during deletion or verify that the deleted project is still selected before navigating.

Fixed in 2fcb3985e9: the removed project is captured before the await and Home is only replaced if it is still the selected project afterwards.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This adds a new mobile background-clone workflow with live progress, cancellation/retry/removal actions, navigation coordination, and a gate that prevents task start until repository files are available. Because it changes several existing production paths and introduces asynchronous state interactions, the runtime behavior warrants human review.

📝 Walkthrough

Walkthrough

The mobile project flow now supports tracked background cloning. The new-task draft observes clone state, blocks submission during cloning, and provides cancel, retry, and remove-project actions with status and error feedback.

Changes

Project clone tracking

Layer / File(s)	Summary
Tracked clone state `apps/mobile/src/state/projectClones.ts`, `apps/mobile/src/state/entities.ts`	Adds pending and snapshot clone states, project-specific clone lookup, and project availability waiting.
Background clone submission `apps/mobile/src/features/projects/AddProjectScreen.tsx`, `apps/mobile/src/features/threads/NewTaskDraftRouteScreen.tsx`	Starts tracked clones when the environment supports them, waits for project availability, and opens the new-task draft with cloning state. Other environments retain the existing flow.
Draft clone controls `apps/mobile/src/features/threads/NewTaskDraftScreen.tsx`, `apps/mobile/src/components/ProjectCloneBanner.tsx`	Displays clone progress and failure states, blocks task start during cloning, and provides cancel, retry, and remove-project actions. Accessibility text reports clone status.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

686-691: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Delay branch loading until cloning completes.
The tracked flow opens this screen before repository files exist. This effect records projectKey and calls flow.loadBranches() immediately. If that call fails or returns no branches, clone completion does not rerun the effect because selectedProject did not change.
This can leave branch selection empty after a successful clone. Worktree mode then keeps Start disabled. Reset the loaded key while cloneBlocksStart is true, and load branches when the clone reaches done or disappears.

Report cancel and retry failures.

Both callbacks discard the AtomCommandResult. reportFailure is also disabled. If either command fails, the banner remains unchanged and the user receives no error feedback.

Await each result and show an alert when AsyncResult.isFailure(result) is true.

Keep Start disabled until projectClones delivers its first snapshot.

startProjectClone returns after the project is created and the background clone starts. AddProjectScreen then opens NewTaskDraftScreen, which starts the separate projectClones subscription. Before its first event, environmentProjectClonesAtom returns []; useProjectClone returns null, so cloneBlocksStart is false and Start is enabled. Keep the pending subscription state distinct from an empty snapshot, and block Start until the first snapshot arrives.

Fixed in 23ab0ab24b: the pending sentinel only blocks Start for the project this draft was opened for by Add Project (a cloning route param), so other projects, offline ones included, can queue tasks as before. A reported clone snapshot still blocks regardless.

openNewTaskDraft resets to NewTaskDraft immediately after startProjectClone succeeds, so the mobile project list can still lack projectId when NewTaskDraftScreen loads. The screen then takes its project-picker return path instead of opening the newly cloned project; wait for the project-create event (as the web flow does) before dispatching this reset.

3	`openNewTaskDraft` resets to `NewTaskDraft` immediately after `startProjectClone` succeeds, so the mobile project list can still lack `projectId` when `NewTaskDraftScreen` loads. The screen then takes its project-picker return path instead of opening the newly cloned project; wait for the project-create event (as the web flow does) before dispatching this reset.

JJulius MarmingeSep 14, 2026

Fixed in bc57a9f8bf: after projectClone.start returns, the screen waits briefly for the project to appear in the client store (mirroring the web palette) before opening the draft.

Expose clone subscription failures instead of mapping them to "pending".

projectClones uses createEnvironmentRpcSubscriptionAtomFamily without a retry or expected-failure handler. A failed subscribeProjectClones stream can therefore leave AsyncResult.value(result) empty. projectClones then maps that failure to "pending", so the UI can remain blocked without a recovery action. Surface the subscription failure or provide a retry action.

Fixed in e767719b1f: a failed subscription now reads as no tracked clone instead of pending, so Start is not held indefinitely; the server's dispatch guard still refuses a turn on a project mid-clone, and the stream is re-established on reconnect.

@juliusmarminge, verified. apps/mobile/src/state/projectClones.ts now maps a subscription Failure to EMPTY_CLONES. Only an unresolved initial subscription remains "pending". This prevents a failed stream from blocking Start indefinitely.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Handle a timed-out project lookup before opening the draft.

waitForProject(..., 3_000) can return null, but this result is discarded. If the project event takes more than three seconds and another project already exists, NewTaskDraftScreen cannot find the generated project and returns to the project picker. The clone then continues without its progress and cancel controls.

Use the result to gate navigation, or keep a cloning route in a loading state until the matching project arrives. Do not treat an arbitrary timeout as project availability.

✅ Addressed in commit 90aa9d7

JJulius MarmingeSep 14, 2026

Fixed in 90aa9d7aea: the destination screen stays in its submitting state until the project appears in the client store (up to 15 s) and only then opens the draft; if it never arrives it reports that instead of navigating into the picker. The clone continues server-side regardless.

CcoderabbitaiBotSep 14, 2026

@juliusmarminge, thanks for the fix. The destination screen now waits for the matching project and only opens the draft after the project is available. A timeout reports an error instead of opening the project picker.
