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.

POTENTIAL BLOCKER

UIScene lifecycle not detected in scanned source

An app built against the iOS 27 SDK without the scene lifecycle does not launch. Apps already shipped, and apps still built against the iOS 26 SDK, keep working.

Standard navigation

source heuristic
79

26 standard navigation site(s), 7 legacy site(s). Sidebar placement is optional.. Standard navigation signals; sidebar placement is optional.

Adaptive layout

source heuristic
48

15 of 465 UI file(s) use fixed geometry · 37 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 heuristic
100

26 of 465 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 heuristic
0

0 of 126 stateful view file(s) preserve state. Share of stateful view files with detected restoration signals; behavior is untested.

Interface idiom

source heuristic
95

442 of 465 UI file(s) free of device-idiom branching. Share of UI files free of layout branching on the device idiom.

Interface orientation

source heuristic
0

0 of 2 orientation site(s) adapt to the scene. Whether the app adapts to scene geometry rather than branching on interface orientation.

Proposed review order

human priority not assessed
01

Confirm scene lifecycle configuration

Confirm the reviewed target, generated declarations and linked SDK before deciding whether lifecycle migration applies. Record an actual launch separately.

02

Review navigation

Inspect legacy navigation in the agreed journeys at narrow and wide sizes. A sidebar is optional; confirm a need before changing navigation.

03

Inspect idiom and orientation assumptions

Confirm target membership and branch intent, then exercise the affected journey across scene sizes and rotation.

04

Inspect fixed geometry

15 of 465 UI file(s) use fixed geometry · 37 icon-sized frame(s) not scored. Confirm whether the fixed size is intentional and reproduce any clipping before changing it.

05

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.
