fix(mobile): paste into the composer, and keep a draft per surface - #6778

Conversation
…omposer **Paste**, without touching the editor. `ComposerRootView` is byte-identical to what shipped. SwiftUI has no paste hook on iOS: `onPasteCommand` and `pasteDestination` are both `@available(iOS, unavailable)`, and `PasteButton` is a button rather than the edit menu. UIKit's route is a paste configuration, and the responder chain is what makes it cheap — the text field keeps taking strings exactly as it does today, and anything it cannot represent walks up to `ComposerPassthroughView`, which the composer already owns for hit-testing. Thirty lines on a view that already exists, and no editor of our own to maintain. Providers resolve to files on disk because the tray takes URIs, the same shape the pickers produce: a file copied in Files arrives as a URL and is copied out of its temporary home, an image copied from Photos or a browser arrives as bytes and keeps its original encoding rather than being re-rendered. **Deletion.** `GlassComposer` has no callers left, so it and its voice stack go, and `expo-speech-recognition` with them — 13 files. One trap there worth naming: that package's config plugin was what injected `NSSpeechRecognitionUsageDescription`. Removing the plugin without replacing the key would have left native dictation terminating the app on its first authorization request. The string now lives in `ios.infoPlist` directly, and a prebuild confirms all four usage descriptions still land in the generated Info.plist. The microphone one was never at risk — `expo-image-picker` supplies it. Claude-Session: https://claude.ai/code/session_01Qriwo2mN6xcnE6A147TXie
Attachments survived every successful send and went out again with the next message. The native composer's `clear()` reaches its own text and nothing else — the tray belongs to React Native. The React Native form it replaced had a `clearAll` that cleared both, and cutting the composer over to a direct `onSubmit` callback left only half of that behind. Shipping since the home screen moved over. Both surfaces now clear the two together, and still only on success: a failed send keeps the draft, so it has to keep the attachments too or the retry sends something different from what failed. Claude-Session: https://claude.ai/code/session_01Qriwo2mN6xcnE6A147TXie
Deleting GlassComposer took the last consumer with it, but the lockfile still carried the package. Also ignores the pasted-attachment scratch directory the workspace writes into. Claude-Session: https://claude.ai/code/session_01Qriwo2mN6xcnE6A147TXie
Leaving the home screen or a workspace threw away whatever was typed there. Text and attachments now survive navigation, scoped per surface — the home screen, and one draft per workspace — and are restored when you come back. Where the state lives was the real question. The tray was already React Native's and cannot move: the pickers, the attachments sheet, paste and the terminal's uploader all mutate it, and the composer only renders a mirror. Putting the text in Swift beside it would make a draft two halves in two languages with two lifetimes to keep in sync, so both halves live in React Native now, in one in-memory store keyed by surface. The composer stays uncontrolled, which is what makes this safe. It reports `onChangeText` outward the way it already reports `onHeightChange`, and takes its text back exactly once, through `restoreDraft` at mount. There is deliberately no `value` prop: a controlled field resizes outside the transaction that reveals send, which is the split-brain the motion rule exists to prevent. Nothing subscribes to the text either — a caller reads it once to hand it back — so typing still causes no React Native render at all. Not persisted across launches. Attachment URIs point into the app's cache, which the OS may evict between launches; within one launch it cannot, and that is exactly this store's lifetime. Two things fall out of scoping it. The single app-wide tray is gone, so an image attached on the home screen is no longer sitting in every workspace — `PromptInputProvider` was only there to hold it and is no longer mounted. And a plain shell now hides the tray rather than showing chips its submit will silently drop, since a workspace's draft is shared across its terminals. Claude-Session: https://claude.ai/code/session_01Qriwo2mN6xcnE6A147TXie
Two bugs, both only visible by driving the simulator — the code read fine. The outward event never arrived. Named `onChangeText`, it collided with React Native's own TextInput event convention and was swallowed before reaching JS, so nothing was ever saved and every restore read an empty store. Renamed to `onDraftChange`, which is also the more accurate name: this reports a draft, not a text field's value. Restoring through the ref raced the view's own creation. At mount the call landed before there was anything to receive it — a 400ms delay made it work, which is the shape of a race, not a fix. The saved draft is an `initialDraft` prop now, delivered as part of setting the view up rather than chasing it, and applied once so later deliveries cannot clobber live typing. `restoreDraft` is gone from the ref; nothing needs it. Verified on the simulator: a draft typed on the home screen survives opening a workspace and coming back; a draft typed in a workspace comes back on return; neither leaks into the other; an image attached on the home screen no longer shows up in a workspace tray; and a send clears text and tray together.

…er sent Both from CodeRabbit on #6778, both real. A failed `copyItem` was swallowed by `try?` and the paste still resolved, handing back an item pointing at a file that was never written — the tray would only find out at upload or preview. `loadImage` ten lines below already guards its write the same way; now `loadFile` does too. And a plain shell was deleting attachments it never sent. Its submit omits them by design, but the clear afterwards wiped the tray anyway — and because a draft belongs to the workspace rather than to one terminal, an image attached in an agent session vanished when a command ran in a shell beside it. The tray is now cleared only when the send could actually carry it; the text always is. Claude-Session: https://claude.ai/code/session_01Qriwo2mN6xcnE6A147TXie

Five commits, all mobile composer. The last three came out of a bug Satya hit in build 16: an image stayed in the tray after sending.

Summary by cubic
Adds iOS paste of files/images to the mobile composer and keeps a per‑surface draft (text + attachments) across navigation. Fixes send/clear semantics so text always clears on success, and attachments clear only when that send could include them; previously attachments lingered and could be resent.
UIPasteConfigurationon the passthrough view; pasted items are written to temp files and emitted viaonPasteas{ uri, name, kind }.usePasteAttachments(<key>)adds them to the tray. Failed file copies are now dropped instead of yielding broken URIs.onDraftChange, and readsinitialDraftonce at mount. A single in‑memory Zustand store (useComposerDraftsStore) holds per‑surface text and attachments (HOME_DRAFT_KEY,workspaceDraftKey); not persisted across launches.onDraftChange; draft restore moved to theinitialDraftprop and is applied once in native. NewonPasteevent.PromptInputProvideris removed; surfaces useuseComposerDraft(<key>)and passonDraftChange/initialDrafttoComposer.GlassComposerand the voice stack; droppedexpo-speech-recognition. AddedNSSpeechRecognitionUsageDescriptioninios.infoPlistto retain native dictation permissions.Written for commit 6fd0c8b. Summary will update on new commits.
