A stable library version alone is insufficient. The proposal must + require no experimental annotation, global integration flag, beta/RC/alpha + artifact, or suppressed opt-in. +2. **Unmet user scenario.** Name one screen, window/device state, and user task + whose accepted contract is not met by the current stable implementation. + Include a reproducible screenshot, UI-tree, issue, or failing test. Code + brevity and similarity to CSS are not user scenarios. +3. **Stable-alternative comparison.** Document why current window-size classes, + Material adaptive/navigation scenes, `Row`/`Column`, `FlowRow`/`FlowColumn`, + and lazy lists/grids cannot meet that scenario. Preserve compact behavior + and existing Navigation 3 restoration/back semantics. +4. **Compatibility proof.** Confirm the resolved dependency graph and API's + documented minimum SDK, then pass the scenario on MusFit's API 28 and API 37 + managed devices. Test compact, medium, expanded, split-screen, and applicable + fold/posture changes without raising `minSdk 28` or weakening target 37 + behavior. +5. **Behavior and accessibility coverage.** Add focused state/layout tests, + Compose semantics assertions, and reviewed screenshots for light/dark, + LTR/RTL, 1.5x font scale, and the relevant window/device states. Visual and + semantic traversal order must remain aligned, especially if Grid placement + or FlexBox ordering can differ from composition order. +6. **Measured benefit.** Capture the current stable implementation and exact + candidate on the same controlled device. Name the metric before the trial. + Require at least a 10% improvement in the selected median/P90 performance + metric or a quantified elimination of the declared layout failure, with no + regression in critical journeys, memory budgets, or lazy behavior. +7. **ADR and rollback.** Add an ADR that records the selected API/artifact, + alternatives, dependency and binary-size impact, test/benchmark evidence, + owner, review date, and the exact stable implementation to restore. The + rollback must be a bounded code/dependency change, not a rewrite. + +## Candidate-specific evidence + +### MediaQuery + +A proposal must identify a capability beyond the current window-size and +Material adaptive scene inputs. It must dynamically test every queried value +that affects UI, including changes while the activity remains alive. Width or +height branching must demonstrate why stable window-size classes are +insufficient and must avoid high-frequency recomposition. Preview/test +injection must cover the queried `UiMediaScope` values. Enabling a process-wide +Compose UI flag is prohibited until the stable API no longer requires it. + +### Non-lazy Grid + +A proposal must prove that the child set is small and bounded and that the +layout needs true two-dimensional tracks, spans, or alignment that the current +stable implementation cannot provide. It must record maximum child count, +intrinsic-measure behavior, composition count, and frame/memory comparison. +Large Food/Training catalogs remain on lazy containers. Any nested lazy content +or flexible track requires an explicit regression test for measurement and +scroll behavior. + +### FlexBox + +A proposal must prove that the bounded item group needs grow, shrink, basis, +wrap distribution, or ordering semantics beyond stable `FlowRow`/`FlowColumn`. +It must test overflow, minimum intrinsic sizes, RTL, font scaling, and +composition-versus-visual traversal order. Large or unbounded collections +remain lazy. Ordering must not create a visual order that conflicts with TalkBack +or keyboard focus. + +## Review cadence + +Recheck this file only when AndroidX publishes a new stable Compose UI or +Foundation line, an applicable MusFit layout issue is accepted, or an official +API status changes.
