Design intentions (stable)

• EditorOnly helper entities never appear in hierarchy or saved scenes. Visualizer proxies are editor-only but selectable; selection resolves to their source entity.
• Jackdaw-inspired roadmap work follows ADR 0020: use Jackdaw as design/API inspiration only unless a ticket explicitly marks code-derived work with source, license, and upstream commit notes. Clean-room implementation is preferred for geometry, terrain, operator, and extension systems.
• Dedicated egui Camera2d at full window — never attach PrimaryEguiContext to a viewport-cropped 3D camera (NaN layout panic).
• Unified viewport uses one render-to-texture target for both the editor fly camera and the possessed player camera so HDR/atmosphere is not broken by sub-viewport cropping.
• PIE: F8 possess/eject while sim runs; F6 pauses/resumes simulation in Play; project settings drive shared rendering for the active viewport camera.
• Asset browser mirrors the on-disk assets/ directory with project tree, breadcrumb, search/filter/sort, grid/list views, texture/model/material thumbnails, a details pane, and context-aware row/menu actions; narrow docks prioritize content, keep the root panel fixed, switch list view to a compact single-column layout, and hide tree/details panes when they would crowd the content area. The footer stays pinned while only the project tree, asset content, and details panels scroll. Built-ins holds spawnable primitives and lights. Materials folder scans assets/materials/*.ron, renders material thumbnails on a sphere using MaterialDesc, and exposes shader-schema-driven parameters/textures in the details editor; Shaders holds shader schema RON files. Audio accepts Bevy-supported Ogg/Vorbis and Speex (.ogg, .oga, .spx), WAV, MP3, and FLAC clips under assets/audio/, with a dedicated filter, waveform icon, format/file details, and stable registry-backed references that retain a runtime source path. glTF/GLB/FBX rows can expand into a shelf of normalized embedded mesh, material, and texture subassets with independent generated thumbnails. Mesh subassets can be selected, dragged into the viewport, or placed from details/context menus; material subassets render source-material spheres; texture subassets can be applied to the selected actor. Model import settings are staged with Apply / Revert, asset context menus can regenerate thumbnails, material asset details edit shared MaterialAsset fields, and file asset deletion moves sources/generated artifacts into assets/.trash/. Before thumbnail loading, glTF sources preflight local external buffers/images and show a stable non-retryable failure state when a dependency is missing instead of repeatedly invoking the asset loader.
• Static/skinned renderer split — model drag/drop uses normalized artifacts under assets/meshes/generated/. Unrigged, non-animated sources create ActorKind::StaticMesh + StaticMeshRenderer; skin-bound or animated sources create ActorKind::SkinnedMesh + SkinnedMeshRenderer and preserve the imported hierarchy. Static slots never contain marked skinned primitives or geometry from animated sources. SceneInstance placement keeps ImportedModel + ModelRef for generic full-source scenes. See ADR 0033.
• Animation authoring — glTF/GLB imports generate UUID-keyed rig/clip manifests and expandable skeleton/clip shelves. Clip drag creates a skinned actor or adds one exact-signature-compatible state to a selected skinned actor through typed history. AnimationControllerDesc exposes named states, ranges, loop/speed, default/crossfade, and non-dirty runtime-backed preview; project validation resolves the same stable refs and blocks animated/skinned FBX with conversion guidance. Production acceptance completed in Gitea #46. See animation-authoring.md and ADR 0031.
• Navigation authoring — bounds, obstacles, areas, and links use typed history and viewport visualizers. Rerecast produces a versioned fingerprinted artifact; Polyanya powers both editor path preview and the game-owned runtime API. The existing horizontal toolbar path button creates or bakes bounds, while Scene > Navigation exposes the complete workflow. See navigation-authoring.md and ADR 0032.
• Brush authoring — ActorKind::Brush + BrushDesc stores persisted convex blockout faces, validates authored geometry in the inspector and Window → Brush Diagnostics, and hydrates active valid brushes into generated mesh children. See brushes.md.
• Draw Brush — B, toolbar pencil, or command brush.draw enters a floor-polygon draw mode. LMB places snapped points, Backspace removes the last point, Enter locks the outline for height editing, mouse up/down adjusts height, and Enter/LMB creates additive prism brushes through history. Esc/right-click cancels. Simple concave outlines decompose into convex brush parts; self-intersections remain blocked.
• Brush edit modes — with a brush selected, 1/2/3/4 enter vertex, edge, face, and clip element modes. Element modes show brush handles in the viewport, own LMB picking, support Shift multi-select, show a mode badge, and Esc returns to object mode. Vertex/edge/face selections use the standard W/E/R gizmo at the element pivot and commit undoable SetBrush edits. Clip previews a bounds-based half-brush and commits with Enter; command-palette intersect, convex merge, and subtract operations use the same preview/commit lifecycle for conservative cuboid/prism blockout.
• Collider split — imported mesh collision lives in a separate ColliderDesc::StaticMesh plus optional RigidBodyDesc; renderer slots own only render visibility, shadows, mesh, and material references.
• Material assets and renderer slots — Material and direct-base Material Instance documents are shared assets. StaticMeshRenderer and SkinnedMeshRenderer each own stable material slots with imported source defaults and explicit shared assignments; Clear returns to the source default, while reimported missing slots retain overrides as orphans instead of matching by name. Runtime-only property blocks never mutate or persist into the shared asset. Custom Surface evaluators use the same constrained ABI for raster and Solari-eligible non-deformed geometry; skinned/morph geometry is deliberately excluded from Solari until deformed BLAS updates exist. See material-system.md, ADR 0035, and ADR 0036.
• Prefab authoring — shared PrefabOverrides targets generated actors by nested anchor chain plus stable ActorId, and applies reflected property/component plus same-layer structural operations in editor and game hydration. The editor supports scoped Revert and transactional Apply to source with three-way conflict checks, exact-file undo guards, and recoverable changed/broken/conflict states. HydratedPrefabMember keeps generated content out of owner serialization; linked-root saves retain local structure as variants. Unpack Layer preserves nested links, while Convert to Local recursively removes them. See prefab-authoring.md and ADR 0027.
• Visual language uses a near-black industrial shell, a compact Blacksite identity mark, restrained amber actions/primary selection, cyan secondary selection, semantic status colors, stable grouped controls, and shared elevated viewport chips. Primary/secondary selection roles remain consistent across hierarchy rows, viewport x-ray shells/corner brackets, the selection HUD, and transform interactions. See visual-language.md.
• Hierarchy shows authored objects plus useful runtime context (Player, PlayerCamera, Project Sun). Ordinary runtime rows remain read-only; generated prefab rows expose override-aware inspection and same-layer remove/reparent actions while rejecting cross-instance/layer and composition-boundary drops. Locks prevent selection, gizmos, drag participation, structural targets, and mutating context actions. Authored reparenting preserves world placement and records parent/local-transform/manual-order changes as one undoable command.
• Player placement is authored through PlayerSpawn; selecting the runtime player in Edit mode redirects to a saved Player Start.
• World lighting has two layers: project default sun/ambient settings, and optional scene-authored directional LightDesc overrides. Scene → Lighting menu and Rendering panel (Window) restore project sun or bake a scene directional from project settings. Apply in Project Settings updates ambient and sun illuminance live.
• Rendering — GiMode + post-process volumes; see rendering.md. Window → Rendering shows requested/effective active-camera stack, fallback reason, Solari eligibility, viewport GI badge, and volume HUD.
• Inspector shows a responsive header, Transform, registered authoring component cards, and an Add Component footer (actor_inspector) that expands an inline search shelf above the button; only the component body scrolls. Rows wrap or stack inside narrow docks instead of forcing the panel wider, and legacy authoring sections use the same component-card shell. Component card carets collapse/expand for the current editor session, status dots toggle persisted AuthoringComponentStates, and triple-dot menus provide registry-backed reset, copy/paste values, move, remove, and documentation slots. InspectorOrder controls presentation only. The Add Component shelf is registry-driven with persistent search, category groups, descriptions, hydration hints, duplicate/conflict disabled states, and recommendation hints. Static game/editor extensions register reflected lifecycle metadata and their inspector together; see extensibility.md and ADR 0034.
• Command palette (Ctrl+P): opens centered, clears and focuses the filter, selects the first result, searches both human-facing labels and stable command IDs, and supports arrow-key selection and Enter to run. Commands include scene.reset_lighting, brush.draw, brush.subtract, brush.intersect, brush.merge_convex, rendering.create_volume, rendering.select_volumes_at_camera, rendering.focus_active_volumes, selection.group, selection.focus, selection.reset_transform, and play commands.
• Editor input routing gives egui text fields first claim on keyboard input. Viewport shortcut keys require viewport pointer focus and are suspended while RMB/MMB camera navigation is active.
• ActorKind remains required as a saved compatibility/display hint, is repaired from primary components on load and component transactions, and does not prohibit compatible composition such as renderer plus light. Component validation owns requirements and geometry-source conflicts.
• Scene persistence and recovery use transactional same-directory writes for authored scenes and bounded user-local recovery snapshots for dirty saved scenes. Recovery runs every 120 seconds by default, keeps five generations, never marks the scene clean, and appears as a status/File-menu restore or discard action when newer than the authored file. Restore leaves the original scene dirty until manually saved. See ADR 0023.
• Scene visualizers expose actor root icons, colliders, lights, player spawns, gameplay markers, volumes, prefab/model anchors, Project Sun, and runtime player/camera markers without changing saved scene data. Spot lights show inner/outer cones and cameras show near/far frusta. Viewport options independently gate visualizer categories and include actor icon and transform-gizmo size sliders.
• Clean game-view overlay (G) hides editor chrome, grid, selection outlines, transform gizmos, actor root icons, visualizers, and selectable proxies without changing camera ownership; Ctrl+G toggles grid.
• Viewport shading (toolbar): Lit (default WYSIWYG), Unlit (base-color debug), Colliders (hide meshes, emphasize collider gizmos). The viewport combines active shading/render path in one bottom-right chip, draws a camera-relative X/Y/Z orientation widget, identifies the primary selection in a responsive top-right HUD, and previews asset placement with a pointer card, placement reticle, corner brackets, and highlighted drop boundary.
• Hierarchy sort modes (Manual, Name, Type) use stable tie-breakers so duplicate names (e.g. several Pillar rows) do not reorder on every click. Actor drags use the full remaining row width as an attach target, show a pointer-following action card, preserve world transforms, reject cycles, keep selected subtrees intact, auto-expand the new parent, and commit one undoable hierarchy command. Manual mode additionally exposes between-row reorder targets and the drag-only Scene Root unparent target.
• Viewport picking: click selects nearest object, generated mesh child resolved to its authored actor, actor root icon, or visualizer hit, with actor icons preferred when clicked over meshes; Tab cycles overlapping targets at the last click. The selection HUD reports the current overlapping-pick position, and additive selections use an amber primary plus cyan secondary treatment. All unlocked selected actors participate in the grouped transform gizmo and one undoable transform command.
• Settings data lives in crates/settings; settings UI lives in settings_ui.rs.

When implementing or changing any of the above, update this file and the root README in the same change.
