-# Material Library And Targeted Viewport Drop
-
-Working implementation plan for Gitea issues
-[`#16`](https://git.spacetrainclubhouse.com/Falling-Metal-Interactive/Blacksite/issues/16) and
-[`#18`](https://git.spacetrainclubhouse.com/Falling-Metal-Interactive/Blacksite/issues/18).
-The shared Material/Material Instance and stable renderer-slot foundation from `#51` is already
-present; this slice completes the production-facing catalog and drag/drop workflow.
-
-## Status
-
-Source audit complete. Implementation starts on a clean branch after collaborative-safety `#49` is
-published, because both slices touch the Asset Browser and should remain independently reviewable.
-
-## Current Gaps
-
-- Material assets are edited inside generic Asset Browser Details; no dedicated Material Library or
-  scene-usage view exists.
-- Viewport material/texture drops act on the existing selection instead of the surface under the
-  pointer.
-- Multi-slot renderers silently assign all slots; the hydrated draw hit already carries
-  `HydratedRendererMaterialBinding`, but the drop path does not use it.
-- Primitive and brush-face targeting is not explicit, and unsupported authored actors can receive a
-  generic `MaterialDesc` instead of an actionable rejection.
-- Drag UI describes an eventual action but does not preview the actual affected surface or restore a
-  preview on cancel/target change.
-
-## Material Library
-
-1. Add a dockable `Material Library` panel, opened from Window and placed in the existing bottom dock
-   without adding another permanent toolbar.
-2. Present project Materials and Material Instances with search, Material/Instance filter, thumbnail
-   grid/list modes, base/dependency health, and source-control status.
-3. Add a scene-usage section that counts renderer-slot, primitive, and brush-face references and can
-   select/locate users. Do not revive ambiguous hidden scene-local material clones.
-4. Reuse the existing guarded Material/Instance drafts for Apply, Revert, Create Instance, and
-   texture-parameter editing. Shared-file edits remain explicit; scene assignment changes use
-   history.
-5. Material and Instance cells are first-class drag sources and preserve the current pointer-following
-   visual identity.
-
-## Targeted Drop Contract
-
-Introduce a frame-updated `ViewportAssetDropTarget` resolved by the existing mesh-picking path:
-
-- A hydrated static/skinned draw maps through `HydratedRendererMaterialBinding` to the authored actor
-  and exact stable slot ID.
-- A primitive maps to its authored actor-level `MaterialDesc`.
-- A brush performs authored face intersection and identifies the stable face ID.
-- An authored but unsupported target remains a visible invalid target with a specific reason.
-- Empty space remains placement-only for placeable assets and invalid for Material/Texture payloads.
-
-Payload matrix:
-
-| Payload | Renderer slot | Primitive | Brush face |
-|---------|---------------|-----------|------------|
-| Material / Material Instance | Assign exact hit slot; one-slot actors may assign directly | Replace actor material reference/values | Replace the hit face material reference |
-| Texture | Reject with guidance to create/edit a Material Instance | Set base-color texture | Set hit-face base-color texture/material binding |
-
-An explicit `Apply All Slots` command remains available from the renderer inspector/library usage
-menu; a viewport hit never silently broadens from one slot to all slots.
-
-## Preview, Commit, And Cancel
-
-1. Start a persistent drop-preview session when a supported Material/Texture payload enters the
-   viewport. Snapshot only the target's affected authored state.
-2. Apply a transient visual preview without pushing history or marking the scene dirty.
-3. When the pointer changes target, restore the previous snapshot before previewing the new target.
-4. On release, restore the transient state first, then commit exactly one typed history/operator
-   transaction to the identified slot, primitive, or face.
-5. On Escape, drag cancellation, leaving the viewport, invalid target, or missing source, restore the
-   exact snapshot and remove every preview/helper marker.
-6. The drag card and target outline name the payload, actor, slot/face, action, and invalid reason.
-
-## Verification
-
-- Unit-test ray-hit to authored target/slot mapping, primitive/face targeting, and invalid reasons.
-- Use `OperatorInvariantHarness` for preview target changes, release commit, Escape/outside cancel,
-  dirty-state preservation, helper cleanup, and one-step undo/redo.
-- Cover static one/multi-slot, skinned multi-slot, primitive, brush face, Texture rejection on a
-  renderer slot, missing material, and linked/locked prefab boundaries.
-- Verify Material Library filtering, scene-usage counts, dependency diagnostics, and drag sources in
-  headless egui tests.
-- Run full source/headless checks. Packaged testing remains deferred until the project owner requests
-  it again; live visual acceptance is still required before closing `#16`/`#18`.

-# Navigation Mesh Authoring, Bake Diagnostics, And Path Preview
-
-Working implementation plan for Gitea issue
-[`#48`](https://git.spacetrainclubhouse.com/Falling-Metal-Interactive/Blacksite/issues/48).
-This is the navigation production loop required by the M7 content-production milestone.
-
-## Status
-
-Architecture, dependency compatibility, composed-source resolution, persisted path samples,
-corrective source-level QA, and live debug-editor acceptance are complete. Packaged/release
-acceptance remains explicitly deferred until the project owner requests another packaged pass.
-
-## Outcome
-
-A level designer can author navigation bounds, obstacles, areas, links, and agent profiles; bake a
-deterministic versioned artifact; inspect stale or invalid data; preview a path in the viewport; and
-use the same artifact through a game-owned runtime query API and headless release validation.
-
-## Architecture
-
-- Shared reflected components own bounds, obstacles, area volumes, links, and scene bake settings.
-- The scene crate owns deterministic composed-source resolution, source fingerprinting, bake
-  artifact IO, the engine-independent query core, and validation.
-- Rerecast performs the 3D walkable-surface bake without coupling navigation to a Bevy plugin
-  release. Polyanya performs proven any-angle runtime and editor-preview path queries.
-- Overlapping primitive and additive-brush triangles enter the deterministic bake source; distant
-  geometry and navigation authoring are excluded from each bounds fingerprint. No synthetic bounds
-  floor is added.
-- The game crate adapts the shared query core to Bevy types and exposes renderer-free artifact
-  validation. Editor preview and project validation do not implement separate pathfinders.
-- Generated artifacts live under `assets/navigation/generated/`, are project-relative runtime
-  dependencies, and never serialize viewport helpers into authored scenes.
-
-## Implementation Sequence
-
-1. Add reflected authoring schema, versioned bake artifact, source fingerprint, validation, and
-   exact agent-profile settings.
-2. Add deterministic Rerecast bake input extraction for authored bounds/obstacles and headless bake
-   command coverage.
-3. Add game-owned artifact loading and Polyanya path-query API, including authored off-mesh links.
-4. Add typed inspectors, create commands, bake/stale status, viewport overlay, and start/end path
-   preview.
-5. Add owner-attributed project validation for invalid links, missing/stale artifacts, unreachable
-   preview samples, and bake failures.
-6. Commit a small sample scene/artifact and run automated, headless, and live debug-editor
-   acceptance. PIE and packaged runtime acceptance remain deferred by project-owner direction.
-
-## Acceptance Gates
-
-- A designer can create bounds and obstacles, bake, view the resulting mesh, and preview a valid
-  start-to-end path.
-- Agent radius, height, climb, and slope settings deterministically affect the bake fingerprint.
-- Relevant geometry or navigation-authoring changes mark the artifact stale; unrelated scene
-  metadata does not.
-- Invalid or dangling links, samples outside the mesh, isolated regions, and bake failures identify
-  the owning actor or setting and provide a repair action.
-- Runtime path queries and editor preview use the same game-owned API and versioned artifact.
-- Helper meshes, lines, endpoints, and bake state are transient and never serialize.
-- Headless bake and project validation pass for the committed sample fixture, and package dependency
-  collection includes the current artifact.
-- Visible subscenes and nested prefab contributors resolve identically from editor snapshots and
-  headless tooling; unsupported structural overrides block with an apply/unpack repair action.
-
-## Deliberate Boundaries
-
-- V1 supports static baked navigation plus explicit links. Dynamic crowd avoidance and runtime tile
-  carving are separate work.
-- Full partial-tile regeneration waits for upstream Rerecast tiling support. V1 records affected
-  source bounds and debounces a deterministic full bake while reporting the dirty region.
-- Area costs are authored and validated in V1; path-cost weighting beyond walkable/blocked areas is
-  deferred until the runtime exposes per-polygon cost callbacks.
-- Imported static meshes remain obstacle-authored in V1 because their normalized manifests do not
-  yet expose deterministic collision triangles to the headless scene crate.

-# Production-Readiness Acceptance Gate
-
-Working plan for Gitea issue
-[`#50`](https://git.spacetrainclubhouse.com/Falling-Metal-Interactive/Blacksite/issues/50).
-This gate is broader than the M7 feature list: it proves the complete daily authoring, content,
-recovery, performance, and release workflow against one exact release-candidate commit.
-
-## Status
-
-Audit in progress. The versioned acceptance matrix exists, but no release candidate is nominated and
-the gate is not signed off. Packaged/release testing remains explicitly deferred until the project
-owner requests it again.
-
-## Sequence
-
-1. Keep one evidence matrix under `docs/editor/evaluations/production-readiness/`; historical H1-H6
-   notes remain context only.
-2. Close implementation blockers before nominating a candidate: collaborative safety `#49`, the
-   remaining Material/drag-drop contract in `#16`, `#18`, and `#51`, terrain `#22`-`#24`, physics
-   placement/diagnostics `#25`-`#26`, and their regression fixtures.
-3. Complete the representative regression project, mutation-invariant coverage, performance budgets,
-   and first-hour workflow tracked by `#32`-`#36`.
-4. Nominate one exact commit, validate it from a clean checkout, and record source/headless results.
-5. When packaged testing is re-enabled, run the candidate's package/build and packaged-runtime
-   matrix without substituting older artifacts.
-6. Run the eight-hour soak and measured performance protocol, consolidate limitations by severity
-   and workaround, and obtain independent first-hour/recovery sign-off.
-7. Post the signed Gitea milestone comment linking the exact commit and immutable evidence. Close
-   `#50` only when every required row passes and no P0 blocker remains.
-
-## Gate Rules
-
-- Feature presence is not acceptance evidence.
-- A local dirty worktree is not a release candidate.
-- Results from another commit or an old package do not transfer to the candidate.
-- Deferred, missing, partial, and implementer-only evidence are not passes.
-- Every failure records an owner ticket or a concrete rerun condition.

-# Renderer, material, and component foundation
-
-## Goal
-
-Separate static and skinned renderer ownership, restore deterministic skinned edit poses, add shared
-material/material-instance slots, and make authoring components registry-driven and composable.
-
-## Component foundation milestone
-
-- Give authoring components immutable IDs distinct from Rust type paths.
-- Split persisted active state from inspector ordering with legacy-state migration.
-- Route presence, persistence, add/remove/reset/copy/paste, and component history through Bevy
-  reflection and atomic transactions.
-- Treat `ActorKind` as a derived compatibility/display hint; validate component data and explicit
-  requirements/conflicts.
-- Provide one statically linked extension registration helper and reflection round-trip fixture.
-- Verify registry integrity, transaction undo/redo, scene save inclusion, composition, and legacy
-  enable-state preservation.
-
-## Related renderer/material milestone
-
-- Keep `StaticMeshRenderer` and `SkinnedMeshRenderer` as separate authoring and hydration paths.
-- Give both renderer types stable imported-source/explicit Material slots and preserve orphaned
-  assignments by ID across source changes.
-- Add versioned Material and direct-base Material Instance assets, sparse editor overrides, shared
-  handle live refresh, and runtime-only property blocks.
-- Capture and restore imported Transform/MorphWeights baselines; sample only the explicitly chosen
-  default edit clip and never reload a rig for a material-only change.
-- Compose one validated Surface evaluator into raster and Solari, including normal/emissive/unlit
-  fields and exact cutout candidate acceptance. Safely omit skinned/morph geometry from Solari until
-  instance-owned deformed vertices and dynamic BLAS updates exist.
-- Upgrade scenes/materials explicitly to schema v4 with dry-run, staged writes, backup, rollback,
-  stable slot normalization, and active-state separation.
-
-## Acceptance
-
-- Shared, scene, game, game-hot, editor, Surface, and maintained Solari-fork tests pass.
-- `cargo --locked validate-levels` reports zero blocking findings.
-- A second project-upgrade dry run reports no changes after apply.
-- Editor evidence shows the stable component cards, static/skinned material slots, Material Instance
-  workflow, deterministic animated actor pose, and Surface/Solari diagnostics.
-- Gitea implementation issue and related roadmap issues link the documentation and screenshot
-  evidence without claiming unsupported dynamic deformed BLAS behavior.

-# Source-Control Status And Collaborative File Safety
-
-Working implementation plan for Gitea issue
-[`#49`](https://git.spacetrainclubhouse.com/Falling-Metal-Interactive/Blacksite/issues/49).
-This is the final M7 implementation slice before the production-readiness acceptance gate.
-
-## Status
-
-Implementation, focused source tests, full editor tests, strict editor clippy, and headless checks
-are complete. Live debug-editor visual acceptance remains pending for a desktop-capable QA session.
-Packaged/release acceptance is explicitly deferred until the project owner requests another
-packaged pass.
-
-## Outcome
-
-External edits cannot be silently overwritten by the editor, common Git/read-only/ownership states
-are visible without dominating the shell, and projects without Git or an ownership provider behave
-normally.
-
-## Implementation Sequence
-
-1. Add exact file revisions, comparison metadata, guarded atomic replacement, and deterministic
-   pre-rename race coverage.
-2. Capture baselines for scene tabs, material/material-instance drafts, and Project Settings;
-   protect prefab source Apply and exact-file undo/redo with the same guard.
-3. Add a non-destructive asynchronous Git scanner and optional ownership-provider registry.
-4. Add compact active-scene and selected-asset status plus a recovery modal with reload, compare
-   metadata, save-as, and cancel.
-5. Cover missing/present/read-only/external-change races, porcelain parsing, provider absence, and
-   document-specific conflict recovery with focused source tests.
-6. Run format, strict affected-crate clippy, source tests, headless validation, and live debug-editor
-   QA. Do not run packaged tests until requested by the project owner.
-
-## Acceptance Gates
-
-- A loaded authored file changed by another process is never replaced by Save, Apply to source, or
-  prefab source history.
-- File creation is also conditional: a file that appears after a save-as baseline is captured is
-  not overwritten.
-- Conflict and read-only UI identifies the path and recovery choices without a force-overwrite
-  escape hatch.
-- Active-scene and selected-asset Git status remain compact and explain themselves on hover.
-- Git absence, a non-repository project, and an empty provider registry are quiet normal states.
-- Git commands are read-only and never alter index, worktree, commits, branches, or locks.
-- Provider state can block an authored write without coupling core editor code to a vendor.
-- Source tests simulate a writer changing the target immediately before rename and prove the old or
-  external content survives.
-
-## Deliberate Boundaries
-
-- Generated registries, imports, thumbnails, navigation bakes, recovery snapshots, and packages are
-  regenerative/system-owned and do not open authored-file recovery UI.
-- V1 compares metadata rather than rendering a text diff; external diff-tool integration is future
-  work.
-- V1 observes ownership/locks. Acquiring, releasing, or stealing locks belongs in a provider-specific
-  follow-up.
-- Git status is project-local and advisory. The content revision guard remains authoritative even
-  when Git is absent or stale.

-- Material and direct-base Material Instance assets live under `assets/materials/`; shader schemas live under `assets/shaders/`. In the Asset Browser, select a Material and use **Create Instance** for sparse inherited variants. Static and skinned renderers own stable per-draw material slots, with explicit assignments taking precedence over imported source defaults; shared edits propagate through live-updated handles without reloading skinned geometry. Custom Surface evaluators share one constrained ABI between raster and Solari-eligible non-deformed geometry. Dynamic skinned/morph Solari geometry and a persisted property-block authoring workflow remain future work; see the [material-system guide](docs/editor/material-system.md).
+- Material assets are RON files under `assets/materials/`; shader schemas live under `assets/shaders/`. `MaterialDesc` stores shader kind, typed parameters, texture bindings, and StandardMaterial fields. The Asset Browser material details editor can apply shader schemas, edit typed parameters/textures, and regenerate sphere thumbnails. Actor inspector material edits live on the actor `MaterialDesc`; static mesh source-material refs remain imported defaults and shared material assets are edited from the Asset Browser.
 - Per-field reflect undo for all components remains future work; typed `shared` inspectors cover the common authoring path.
 - The authoring/hydration layer is intentionally small so richer asset workflows (terrain,
   material graphs, lighting profiles) can be added without changing the scene format foundation.
