Problem

The mobile new-task flow (selected project, bound draft, submitting, expanded provider) was a single set of useState in NewTaskFlowProvider, shared by every draft route. Each draft route wiped it with a useLayoutEffect reset on mount and rendered nothing until that reset ran. A draft opened by id (list row, deep link, restored state) was bound by an effect that awaited draft hydration and re-ran on every project list change.

Change

new-task-flow-state.ts: flow state lives in a module atom keyed by the draft route's flow key (route key + draft identity). resolveRouteDraft derives what a route's draftId means (pending / missing / open). Readiness is per environment: stampedEnvironmentProjectsLoading keeps the route pending while the draft's stamped environment is connecting, unread, or synchronizing, using the same signals as threadRouteIsHydrating. pruneNewTaskFlowStates drops the flow of every draft route that left the stack.
use-composer-drafts.ts: composerDraftsLoadedAtom, a plain state atom that hydration sets, so render can tell whether drafts have hydrated. Reading it starts no I/O: hydration starts at app start with the attachment upload worker (installComposerAttachmentUploads). A failed load stays not-loaded and is retried by the next ensureComposerDraftsLoaded caller (the draft route's useComposerDraft mount, draft edits, outbox delivery); the route re-resolves as soon as it succeeds.
new-task-flow-provider.tsx: reads and writes the flow for its flowKey; binds the route's draft in render; any flow write stores that binding. reset and openDraft are gone. Adds getSelectedProjectKey (read after an await) and missingRouteDraftId. The provider serves only the topmost draft route, so a draft screen returns to the picker only when missingRouteDraftId is its own draftId; a covered draft route never reads the top route's missing state.
Stack.tsx: passes the last draft route's flowKey; active is "that draft route is the topmost Thread" (draftRouteOnTop).
App.tsx: prunes flows in the existing navigation state change handler, next to pruneNewTaskBranchCheckouts.
NewTaskDraftRouteScreen.tsx: no reset effect and no initialized gate. A new route has a new key, so it starts fresh.
NewTaskDraftScreen.tsx: the draft-open effect and the selectedProjectRef sync are gone. A missing draft or project uses the existing return-to-picker path, which still clears its flag once the requested project arrives, as on main.

What this improves

Sync removed: the reset layout effect and its gate render, the draft-open effect (an async hydration wait that re-ran on every project list change), and a ref-sync effect.
Renders avoided: each draft route mount no longer runs a reset setState across the whole provider tree plus a gate render.
No bug-fix claims. The per-route isolation is covered at the store level in new-task-flow-state.test.ts, but I have no failing-on-main test for the component-level case, so it is listed under behavior changes instead.

Behavior changes

Each draft route keeps its own selection. Opening draft B above draft A (via a pushed thread) no longer wipes A's project or draft binding, so Back to A shows A's draft, not a fresh empty one. A screen remount of the same route also keeps its selection; before, the reset cleared it.
A route whose draftId names a draft that is gone, or whose project is gone, now replaces the draft route with the project picker (the existing return-to-picker path, after one frame). Before, it pushed the picker on top of a draft screen that was falling back to another project.
While drafts are hydrating, or the draft's own environment is still loading its projects, a draft-id route has no selected project and shows the screen's existing empty state (as main does before any project loads). It no longer falls back to another environment's project, and no longer creates a throwaway draft for the first project in the meantime.
Multi-environment cold launch: a draft stamped to environment B now waits for B's projects. Before (on main too), it was treated as missing as soon as any environment's projects loaded, and the route went to the picker. Once B has settled without the project (live, offline, reconnecting, failed, or removed), the route goes back to the picker as before.
Unchanged from main: after a route's draft is bound, a later removal of its project falls back to the environment's first project, as main's openDraft binding did.
Flow state for routes that left the stack is pruned on navigation state change. A flow now outlives a pushed live Thread above it, which is what keeps A intact.
The cloned-project removal continuation compares the flow's stored project key, not the last rendered selected project.

Effects (counted by hand)

NewTaskDraftRouteScreen.tsx: 2 -> 1 (reset useLayoutEffect removed; the branch checkout release effect stays)
NewTaskDraftScreen.tsx: -2 (selectedProjectRef sync, draft-open effect)
new-task-flow-provider.tsx: 1 -> 1. The draft-creation effect stays because the draft key must exist before the composer mounts; it now writes the flow atom and skips draft-id routes.
Stack.tsx, App.tsx, use-composer-drafts.ts, new-task-flow-state.ts: 0 -> 0

Verification

vp test run src/features/threads/new-task-flow-state.test.ts (apps/mobile): 9 passed. "waits for a slower environment's projects while another environment's have loaded" failed on 1f49c486d3.
Multi-environment cold launch was not checked on a device: the test setup has one environment.
vp test run src/features/threads/new-task-flow-state.test.ts (apps/mobile): 6 passed
vp run check:changed: format, lint, knip 1/2 and 2/2, typecheck, test all pass
No test for the covered-draft-route case: it needs two stacked NewTaskDraftScreens with the full composer mounted.
Rebased onto main after #25793 (share-import state machine); vp test run incomingShareImport new-task-flow-state: 21 passed.
Android (Pixel 9, pool) after the rebase: new task from Home, type, back out, reopen from Unsent (text and project kept); missing-draft deep link replaces the route with the project picker, and Back lands on Home; the share-unavailable link shows the inline note; send, thread switch, Home and Settings work. Not exercised: pushing a thread above a draft (a thread deep link collapses the stack to Home plus the thread, and the in-app push needs a thread context chip in the draft).

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This refactor changes production mobile draft-route lifecycle and composer behavior by introducing route-keyed persistent flow state, hydration/readiness resolution, and navigation-driven pruning. Its scope spans navigation, draft restoration, project selection, and submission state, so human review is appropriate.

Walkthrough

The mobile app stores new-task flow state by draft route, resolves route drafts against loaded drafts and projects, and removes state for routes no longer on the navigation stack. Draft screens handle missing route targets through the project picker.

Changes: Mobile new-task draft flows

Layer / File(s)	Summary
Flow state and route-draft resolution `apps/mobile/src/features/threads/new-task-flow-state.ts`, `apps/mobile/src/state/use-composer-drafts.ts`, `apps/mobile/src/features/threads/new-task-flow-state.test.ts`	Adds keyed flow state and route-draft resolution. `composerDraftsLoadedAtom` exposes composer-draft hydration status. Tests cover route resolution, project-loading status, and pruning.
Provider integration with keyed flow state `apps/mobile/src/features/threads/new-task-flow-provider.tsx`	The provider resolves route drafts and stores flow selections, submission state, and expanded-provider state by flow key. Its context exposes the selected project key and missing route-draft status.
Navigation and missing-target handling `apps/mobile/src/Stack.tsx`, `apps/mobile/src/App.tsx`, `apps/mobile/src/features/threads/NewTaskDraftRouteScreen.tsx`, `apps/mobile/src/features/threads/NewTaskDraftScreen.tsx`	Navigation associates the provider with the draft route and prunes state for routes no longer present. Draft screens no longer reset the flow or wait for draft hydration to open a route draft. The project-picker flow handles missing route targets.

Merge Risk: External image Moderate · up to 55fa9

Pushing a second draft route above an existing one can cause the lower draft's late project resolution to change the upper draft's project. Deleting a project that was only shown through the default fallback also no longer returns the user Home. Both should be addressed or accepted before merge. Cold-launch handling of multi-environment drafts looks correct.

Handle hydration rejection for draft-ID routes.

loadPersistedComposerState() can reject during file access or decoding. The rejection handler clears loadPromise but does not update composerDraftsHydratedAtom. The mounted provider therefore keeps draftsLoaded false, and resolveRouteDraft() remains pending. NewTaskDraftScreen replaces the route only for routeTargetMissing, so the draft-ID route can remain open without a bound draft. Later unrelated callers may retry hydration, but the route has no retry or error boundary.

Keep hydration unsuccessful on error, but send the route to the project picker when its load promise rejects.

JJulius Marminge3d ago

Fixed in 70f4389b9d: composerDraftsLoadedAtom is now plain state (Atom.make(false), set to true when hydration completes); reading it starts no I/O. Hydration starts at app start via installComposerAttachmentUploads, and a failed load is retried by the next ensureComposerDraftsLoaded caller.

CcoderabbitaiBot3d ago

@juliusmarminge The supplied code confirms that reading composerDraftsLoadedAtom starts no I/O. It also confirms that a failed load clears loadPromise, which permits the next caller to retry.

That change does not establish recovery for an already-mounted draft-ID route. If no later caller starts hydration, composerDraftsLoadedAtom stays false and the route can remain pending.

The remaining check is a hydration failure while a draft-ID route is mounted. Verify that the route triggers a retry or provides an exit without requiring an unrelated action. The read-side I/O concern is addressed; the route-recovery concern remains unverified.

Compare the displayed project after removing its clone.
The provider can show the first project while the stored projectKey stays null. The automatic draft-creation write sets only draftKey, so the stored key is not updated. getSelectedProjectKey() returns that stored key, not the displayed project. After a successful delete of the displayed fallback project, the comparison at line 236 is false, so the screen does not replace itself with Home. The screen stays on the draft, and the displayed project changes to another project.
Compare against the project the screen displays after the deletion, or store the effective project when the draft is created. Choose one approach and verify its effect on the project list and draft state.

Keep pending route drafts unselected and preserve their pending surface.

When environment A loads before the route draft’s stamped environment B, resolveRouteDraft returns pending, so the provider retains the empty flow state. The provider then selects A because selectedProjectKey is null and selectedProject falls back to projectsForEnvironment[0]. NewTaskDraftScreen receives A and renders its project control and picker.

Gate this fallback on routeDraftResolution.kind === "pending" and keep selectedProject null until the route opens. The current screen returns null for a null project, so also preserve or add the intended pending composer surface; changing only the provider would blank the route instead of showing the promised project-free composer.

✅ Confirmed as addressed by @juliusmarminge

JJulius Marminge3d ago

Valid, and the readiness fix above widened the window, so I fixed it in 55fa95c9da. While resolveRouteDraft returns pending, the provider now sets selectedProject to null instead of falling back to the first loaded environment's first project. Start can no longer target that project. The screen keeps its existing empty state (it returns null without a project), which is what main shows on a cold launch before any project has loaded. It opens as soon as the stamped environment delivers the project.

CcoderabbitaiBot3d ago

@juliusmarminge The supplied code confirms that pending keeps selectedProject null, and buildPendingTaskMessage returns null without a project. This addresses the wrong-environment send risk.

Keeping the existing empty state is reasonable. My request for a separate pending composer surface was unnecessary.

Keep covered draft screens isolated from the top route’s flow.
When draft B covers draft A, A’s no-draftId project-resolution effect can call setProject after A’s project loads. The shared provider now uses B’s flowKey, so carryDraftContentTo reads B’s draft key and retargetNewTaskDraft retargets B’s draft to A’s project. Guard route-driven writes with the caller’s route key or provide each screen with its own flow context.
