ApprovabilityVerdict: Approved at Macroscope's review found this PR approvable — This is a small, focused iOS bug fix that replaces global screen geometry with the containing scene’s width and display scale. Its runtime impact is limited to correctly sizing chips, hairlines, and terminal rendering on resizable or external displays, with no new workflows or broader system changes.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not treat an unmeasured width as a valid chip width.
If setControlledDocumentJson runs before the view enters a window, both textView.window?.bounds.width and bounds.width can be zero. maximumLabelWidth then falls back to only chipFontSize * 3, so long chips are truncated during makeAttributedDocument. Later layout does not rebuild the attributed document. Treat zero as “not measured” and rebuild after the text container receives a non-zero width.

…UIScreen.main iOS 27 makes iPhone apps resizable and SDK 58 stops reading UIScreen.main across Expo. The terminal, review diff, and composer views now take their display scale from the trait collection and the fallback chip width from the window they sit in, so hairlines and chip truncation stay right when the app is not full screen or is on another display.

Stacked on #12049. iOS 27 makes iPhone apps resizable and SDK 58 stops reading
UIScreen.mainacross Expo. Our terminal, review diff, and composer views still did, for hairline widths, Metal content scale, and the fallback chip width.They now take the display scale from the view's trait collection and the fallback width from the window they sit in, so hairlines and chip truncation stay right when the app is not full screen or is on another display.
Validation: the full stack compiles on Xcode 27 (Debug simulator build). No behavior change on a full-screen phone.
Model: Claude Fable 5. Harness: Claude Code.
