Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The new iOS paste flows can submit unsupported task attachments, race attachment preparation, mutate terminal drafts after cancellation, or block normal text insertion at the attachment limit, while the added UI test may be flaky because of system paste-permission prompts.

Add behavior coverage for copyFile.
These assertions verify action visibility only. They do not exercise ChatArtifactViewerPageModel.copyFile, materialization, pasteboard assignment, cancellation, or failure state. Add hermetic success and failure tests through injectable service boundaries before relying on these expectations as coverage for the complete feature.

Enforce attachment capability in the shared paste action.
showsAttachmentButton rejects plain-shell templates and Macs without task-attachment support. stagePasteboardAttachments() does not check that capability. A native image or file paste can bypass the UI gate and create attachments for an unsupported route.
Return false when showsAttachmentButton is false. This keeps unsupported payloads on UIKit's native paste path.
As per coding guidelines: “When behavior has multiple entrypoints, implement one shared action path and verify every entrypoint rather than duplicating logic.”

Move pasteboard loading and fallback PNG encoding into asynchronous staging.
pasteboardImageData synchronously materializes pasteboard.image and runs pngData() before the utility staging task starts. The staging limits and background ImageIO work cannot protect this MainActor path. Use an asynchronous item-provider or file representation so source limits apply before decoding and encoding.

Make attachment and artifact-copy operations lifecycle-owned and identity-checked.
A cancelled attachment-staging task can finish after a newer paste and clear the newer attachmentStagingTask, re-enabling submit while staging is still active. Cancellation also no longer reliably cancels the current operation on dismissal. Track an operation identity, clear state only when the finishing task still owns it, and apply the same ownership rule to every staging entrypoint.
The inline and pager artifact-copy actions likewise launch unowned tasks that can outlive a dismissed or replaced viewer and still materialize a file or update the global pasteboard. Store and cancel one copy operation owner for both paths so stale completions cannot update later UI state or the clipboard.

Do not consume plain-text paste when the attachment limit is reached.
The guard returns true before the method checks whether the pasteboard contains a supported image or file. When remainingAttachmentCount == 0, plain-text paste is reported as handled, so the prompt editor skips native text insertion. Detect the payload first, then apply the count alert only for supported attachments.

Stop cancelled image staging before it updates terminal state.
stagePastedImage cancels this task on a terminal switch or disappearance. stageImage and data(for:) can still return after that cancellation. The task then adds the stale image to the outgoing terminal's pending attachments. The catch path can also show an unreadable-file alert for cancellation.
Check cancellation after each await. Ignore CancellationError without setting attachmentErrorMessage.

around lines 507 - 535, Update stagePastedImage so it checks for cancellation
immediately after each await of stageImage and data(for:) before mutating

switch or disappearance. In the catch path, ignore CancellationError without
setting attachmentErrorMessage, while preserving the existing unreadable-file
message for other errors.
