Files exceeding the 150-line ceiling defined in CLAUDE.md. Ordered by size descending.

File	Lines	Primary concern	Suggested split
editor/state/GraphynEditorState.kt	135 ✅ split done	Coordinator: workflow mutations, selection, dispatch	Sub-states extracted: GraphynNodeLayoutState (82L), GraphynViewportState, GraphynDebugLogState; viewport fit/resize actions in GraphynEditorViewportActions.kt
editor/canvas/GraphynCanvasSurface.kt	113 ✅ split done	Canvas orchestrator	Extracted: GraphynCanvasGestures (gestures), GraphynConnectionMidpoints, GraphynNodePortDots (port dots with hover + reconnect)
editor/theme/GraphynTheme.kt	262	Color schemes, typography, palette presets, appearance state	Split into GraphynPalette.kt, GraphynColorScheme.kt, GraphynTypography.kt, GraphynAppearanceState.kt
editor/canvas/components/GraphynNodeCard.kt	237	Card shell + drag + port columns + port bubbles + summary section	Extract GraphynPortColumn + GraphynPortBubble → GraphynNodeCardPorts.kt; extract GraphynSummarySection → GraphynNodeCardSummary.kt
editor/shell/components/GraphynMinimapDebugger.kt	175	Minimap draw + viewport rect + node rects + telemetry overlay	Split minimap Canvas draw logic into GraphynMinimapCanvas.kt
editor/shell/GraphynEditorShell.kt	175	Shell scaffold + panel layout + slot wiring	Shell layout is already thin; split only if panel wiring grows
