Suspicious Defects

Ignored for player conformance

Scope of RemoteCompose Conformance Testing

This conformance suite indexes 252 gold specification files spanning all 18 RemoteCompose subsystems. Verification includes box coordinate trees, dynamic math expression evaluation, multi-frame particle simulations, binary wire macros, 2D vector drawing commands & text-on-path glyph placement, AGSL/gradient shaders & uniform bindings, clock second-hand sweeps, touch dispatch, text buffer transforms, light/dark themes, dynamic float lists, path morphing, accessibility semantics, autonomous wake/impulse scheduling, conditional branch execution, matrix expression evaluation, and animation specifications.

⚠ Suspicious Reference Implementations (3 Tests Tagged)

The following tests generate outputs from the Java reference implementation that exhibit known reference defects, modifier omission, or specification contradictions. They are tagged with tags: ["suspicious"] and excluded from player conformance requirements until the reference implementation is corrected:

collapsible_column_scroll: CollapsibleColumn decides which child to collapse by measuring against the viewport (CollapsibleColumnLayout.java:302-319), but ColumnLayout then positions the survivors against the virtual scroll dimension (ColumnLayout.java:316-325) and centres against it (ColumnLayout.java:412-414). That dimension is the pre-collapse 240px, so the two surviving 80px children are centred with a (240-160)/2 = 40px top offset: the collapse frees no space, it only moves the content down. The collapsed child is recorded at the end cursor (y=200). No children overlap.
collapsible_row_scroll: Horizontal mirror of collapsible_column_scroll: the collapse is decided against the viewport, but RowLayout positions the survivors against the pre-collapse virtual scroll dimension (RowLayout.java:336-347, 472-474), leaving a (240-160)/2 = 40px offset the collapse never reclaims. Separately, the collapsed child is recorded at x=40, the same position as the first surviving child, because RowLayout.java:546-550 assigns x before the isGone check. That is a shared coordinate, not a painted overlap: the child is GONE and is never drawn.
flow_max_lines: FlowLayout.segmentComponents runs several times over a single MeasurePass and never clears the GONE flags an earlier pass set -- contrast CollapsibleRowLayout.java:253, which calls clearVisibilityOverride first -- and it treats a GONE child as 0x0 (FlowLayout.java:233-235). The fifth child, correctly dropped by maxLines=2, is therefore re-segmented into the last row and recorded spanning x=200..300, outside the 260px container. It stays GONE and is never painted, so the defect is confined to the reported geometry.

collapsible_column_scroll 📸 Visual PNG SUSPICIOUS (REFERENCE DEFECT)	Layout	150×200 @ 1x	5 items BoxLayout RootLayoutComponent ColumnLayout CollapsibleColumnLayout	CollapsibleColumn container combined with verticalScroll modifier Defect: CollapsibleColumn decides which child to collapse by measuring against the viewport (CollapsibleColumnLayout.java:302-319), but ColumnLayout then positions the survivors against the virtual scroll dimension (ColumnLayout.java:316-325) and centres against it (ColumnLayout.java:412-414). That dimension is the pre-collapse 240px, so the two surviving 80px children are centred with a (240-160)/2 = 40px top offset: the collapse frees no space, it only moves the content down. The collapsed child is recorded at the end cursor (y=200). No children overlap.

collapsible_row_container_gone	Layout	60×100 @ 1x	4 items BoxLayout RootLayoutComponent RowLayout CollapsibleRowLayout	CollapsibleRow where available width cannot accommodate even highest priority child, collapsing container to GONE

collapsible_row_priority_collapse 📸 Visual PNG	Layout	250×100 @ 1x	5 items BoxLayout RootLayoutComponent RowLayout CollapsibleRowLayout	CollapsibleRow where lowest priority child collapses and is marked GONE when space is insufficient
collapsible_row_scroll 📸 Visual PNG SUSPICIOUS (REFERENCE DEFECT)	Layout	200×100 @ 1x	5 items BoxLayout RootLayoutComponent RowLayout CollapsibleRowLayout	CollapsibleRow container combined with horizontalScroll modifier Defect: Horizontal mirror of collapsible_column_scroll: the collapse is decided against the viewport, but RowLayout positions the survivors against the pre-collapse virtual scroll dimension (RowLayout.java:336-347, 472-474), leaving a (240-160)/2 = 40px offset the collapse never reclaims. Separately, the collapsed child is recorded at x=40, the same position as the first surviving child, because RowLayout.java:546-550 assigns x before the isGone check. That is a shared coordinate, not a painted overlap: the child is GONE and is never drawn.

flow_max_lines 📸 Visual PNG SUSPICIOUS (REFERENCE DEFECT)	Layout	260×400 @ 1x	7 items BoxLayout RootLayoutComponent FlowLayout	Flow layout with maxLines constraint limiting wrapped rows Defect: FlowLayout.segmentComponents runs several times over a single MeasurePass and never clears the GONE flags an earlier pass set -- contrast CollapsibleRowLayout.java:253, which calls clearVisibilityOverride first -- and it treats a GONE child as 0x0 (FlowLayout.java:233-235). The fifth child, correctly dropped by maxLines=2, is therefore re-segmented into the last row and recorded spanning x=200..300, outside the 260px container. It stays GONE and is never painted, so the defect is confined to the reported geometry.

interaction_click_button 📸 Visual PNG	Layout	300×200 @ 1x	6 items BoxLayout RootLayoutComponent	Touch click interaction switching StateLayout state, then settling: the click swaps the active child immediately but the container resize is animated, so the layout update is only observable on a later frame.

modifier_marquee_ticker 📸 Visual PNG	Layout	300×100 @ 1x	3 items BoxLayout RootLayoutComponent	Marquee modifier scrolls overflowing text over time: the offset stays at rest through the initial delay, then sweeps out to the full overflow distance and back over one cycle
modifier_multi_click 📸 Visual PNG	Layout	200×200 @ 1x	2 items BoxLayout RootLayoutComponent	Three MultiClick modifiers on one Box route single click, long press and double click to three independent StateLayouts. Each gesture flips exactly one of them, so the layout tree tells the three click types apart from one another, from a misrouted gesture, and from one that was dropped. The settle steps then observe the StateLayout resize animation each flip starts.

Two boxes carry different specs; each must report its own durations and easing, and its animation id must match the spec
animation_spec_defaults_and_disable	AnimationSpec	3 spec assertions	3 items AnimationSpec ComponentBinding SpecDefaults	A component with no ANIMATION_SPEC must fall back to the default spec (id −1, 300 ms, CUBIC_STANDARD, FADE_IN/FADE_OUT) and stay animation-enabled, while animationId 0 is the one and only value that disables animation
