Source audit under contract v5. It reports source signals, not runtime verdicts: no Duo build was run and compatibility is unverified. Re-run the current CLI on your own revision before making decisions.
Hours are unvalidated heuristics, not measured delivery time or a quote. This index retains only a sample of findings and partial coverage metadata; target membership and build settings are unresolved. No human priority has been validated. Scores across contracts are not comparable.

FoldReady CLI · result contract v5 · 331 UI files audited, 2314 excluded (tests, previews, vendored)
Signal: 69/100 (B), contract v5, over 331 UI files. This is a versioned source summary. 0 potential lifecycle signal(s) require build confirmation. Runtime compatibility and human priority are unassessed.

Adaptive layout
source heuristic2 of 331 UI file(s) use fixed geometry · 18 icon-sized frame(s) not scored. Share of UI files free of fixed screen geometry. Icon-sized frames, previews and tests are not scored.
Adaptive geometry
source heuristic6 of 331 UI file(s) read size classes or effective geometry. How widely the app reads size classes and scene geometry. Absence of any read is not scored zero.
State preservation
source heuristic0 of 69 stateful view file(s) preserve state. Share of stateful view files with detected restoration signals; behavior is untested.
Interface idiom
source heuristic327 of 331 UI file(s) free of device-idiom branching. Share of UI files free of layout branching on the device idiom.
Interface orientation
source heuristic1 of 3 orientation site(s) adapt to the scene. Whether the app adapts to scene geometry rather than branching on interface orientation.
Findings
sample · 14 of 82 rows| Severity | Check | Signal and confidence | Location |
|---|---|---|---|
| major | adaptive-layout | UIScreen.main.bounds is a fixed geometry read; use the view's own bounds or the window scene. Confidence: not retained in this index; re-run CLI. Runtime: not tested. | SignalServiceKit/Messages/Attachments/V2/Thumbnails/AttachmentThumbnailQuality.swift:52 |
| minor | adaptive-layout | UIScreen.main is deprecated in iOS 27; derive scale and geometry from the window scene and trait collection. Confidence: not retained in this index; re-run CLI. Runtime: not tested. | SignalServiceKit/Util/UIDevice+FeatureSupport.swift:13 |
| minor | adaptive-layout | UIScreen.main is deprecated in iOS 27; derive scale and geometry from the window scene and trait collection. Confidence: not retained in this index; re-run CLI. Runtime: not tested. | SignalServiceKit/Util/UIDevice+FeatureSupport.swift:71 |
| minor | build-toolchain | Xcode 27.1 or later is required to use all of the available screen space on iPhone Duo; below it the app does not extend under the status bar and camera. LastUpgradeCheck reads 2600, which records the last Xcode upgrade and can be stale: confirm the toolchain that actually builds the app. Confidence: not retained in this index; re-run CLI. Runtime: not tested. | Signal.xcodeproj/project.pbxproj |

Proposed review order
human priority not assessedInspect idiom and orientation assumptions
Confirm target membership and branch intent, then exercise the affected journey across scene sizes and rotation.
Inspect fixed geometry
2 of 331 UI file(s) use fixed geometry · 18 icon-sized frame(s) not scored. Confirm whether the fixed size is intentional and reproduce any clipping before changing it.
Test state across a resize
Set selection, scroll and input state, resize, then revisit the journey. Record any loss before choosing a restoration change.
Patch proposals are not generated in this report. Run the current CLI to prepare a reviewed work order.
Validate the signals with a human review.
A reviewer confirms target relevance, journey impact and the next test. Re-scanning can show changed signals; it cannot prove runtime fixes.
