🟡 Medium components/ChatView.tsx:7510
Completed worktree sends with attachment previewUrl blob URLs remain in rememberPendingWorktreeSetup indefinitely when the user navigates away and does not remount ChatView, leaking the message record and blob resources for the lifetime of the tab. The record is only cleared by mounted cleanup or a later send/failure; remove it when the setup/turn completes and revoke its attachment URLs during eviction.

- The unmount cleanup now skips messages a pending worktree setup still owns (
isPendingWorktreeSetupMessage), so a blob preview URL survives navigation and the restored optimistic row keeps a valid image. Once the server owns the message, the existing reconcile path hands the URL off to the persisted row and the handoff cleanup revokes it. - Records are capped at 8. Remembering a newer setup evicts the oldest abandoned record and revokes its retained preview URLs. Normal clears (turn owned, send failure, superseded) do not revoke on their own, because by then the preview handoff owns the URL.

🟡 Medium components/ChatView.logic.ts:389
Leaving a thread after a worktree send with an image revokes the blob: URL retained in pendingWorktreeSetups, so returning to the thread restores an optimistic message whose preview URL is already invalid and the image stays broken until server persistence. ChatView's unmount cleanup must exclude messages retained by rememberPendingWorktreeSetup from revokeUserMessagePreviewUrls, then revoke them when the pending record is finally cleared.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR changes production worktree-send lifecycle behavior by retaining optimistic state and attachment previews across navigation, then restoring subscriptions on remount. The cross-cutting state and resource cleanup logic, together with unresolved medium-severity lifecycle concerns, warrant human review. Not approved because:

🟡 Medium components/ChatView.logic.ts:407
Starting a ninth setup discards the oldest record even when its setup is still running, so returning to that thread loses the optimistic message and setup card and cannot re-subscribe to the setup. Evict only records whose setup has completed or otherwise stopped running, rather than evicting solely by age.

5605-5635: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winThe new persistence behavior is only tested through the module-level helper APIs. Add a ChatView-level test that starts a worktree setup, remounts the view, and asserts that the optimistic message and running setup state are restored; the current tests would not detect a regression in the remount integration this PR is intended to fix.

Starting a thread in a new worktree keeps the setup card and the composer's optimistic user message only in
ChatViewcomponent state. Navigating away and back remountsChatView, so both are dropped while the server is still building the worktree: the thread renders its empty "Send a message to start the conversation" state even though setup is still running, and the message is not persisted until the turn starts.This keeps the pending send at module scope, alongside the existing held-timeline state, and addresses it by both the draft owner key and the scoped thread key. On remount
ChatViewrestores the optimistic message and re-subscribes to the server's running setup snapshot, so the card and message come back. The record is dropped once the server owns the turn, on send failure, or when a new send supersedes it.Verified in the web client against a local server with a slow setup script: leaving and returning (browser back/forward, and opening the bootstrap thread from the sidebar) keeps the setup card and the message, and the turn still starts normally once setup finishes.
Before: setup state lost after leaving and returning
After: setup card and message restored after leaving and returning
