f0fa067566 feat(core+app): Phase 6.4 — per-frame animation playback (breathing/idle cycles)
Phase 6.1-6.3 resolved the right cycle and rendered its first frame
as a static pose. Phase 6.4 actually walks the cycle over time so
creatures, characters, and props animate their idle motion — the
breathing the user noticed was missing after Phase 6.1.

MotionResolver gains GetIdleCycle() returning IdleCycle(Animation,
LowFrame, HighFrame, Framerate). The existing GetIdleFrame() now
shares a private ResolveIdleCycleInternal helper, so the resolution
algorithm (motion-table override, stance/command priority, fallback)
is identical for both entry points and stays in one place.

WorldEntity.MeshRefs becomes a get/set so the per-frame tick can
swap in fresh per-part transforms without rebuilding the entity.
Static decorations never get touched.

GameWindow keeps a Dictionary<entityId, AnimatedEntity> for entities
whose motion table resolved to a multi-frame, non-zero-framerate
cycle. AnimatedEntity caches a per-part template (gfxObjId +
surfaceOverrides + scale) snapshot taken from the hydration pass so
the tick doesn't redo AnimPartChange/TextureChange resolution every
frame — only the per-part transform matrices are recomputed.

OnRender calls TickAnimations(dt) before Draw. The tick advances each
entity's CurrFrame by dt*Framerate, wraps it inside [LowFrame, HighFrame],
samples the corresponding AnimationFrame, and rebuilds the entity's
MeshRefs by composing scale → quaternion rotate → translate per part
in the same order SetupMesh.Flatten uses, then baking the entity's
ObjScale on top in the same PartTransform * scaleMat order as the
hydration path.

160 tests green.

733f8ff601 feat(net+app): SubPalette overlays applied to palette-indexed textures (Phase 5b)
Implements the other half of ObjDesc: SubPalettes (palette-range
overlays) that repaint palette-indexed textures with per-entity color
schemes. Ported algorithm from ACViewer Render/TextureCache.IndexToColor
after the user pointed out I was prematurely implementing from scratch
instead of checking all the reference repos.

The Nullified Statue of a Drudge sends (setup=0x020007DD with a drudge
GfxObj animPart replacing part 1, plus 2 texChanges targeted at part 1,
plus 1 subpalette id=0x04001351 offset=0 length=0). The TextureChanges
swap fine detail surfaces; the SubPalette with length=0 ("entire palette"
per Chorizite docs) remaps the drudge's flesh-tone palette to stone.
Without this commit, the statue looked like a normal flesh drudge
because palette-indexed textures decoded with the base flesh palette.

Added:
  - Core/World/PaletteOverride.cs: per-entity record carrying
    BasePaletteId + a list of (SubPaletteId, Offset, Length) range
    overlays. Documents the "offset/length are wire-scaled by 8"
    convention and the "length=0 means whole palette" sentinel.
  - WorldEntity.PaletteOverride nullable field. Per-entity (same across
    all parts), in contrast to MeshRef.SurfaceOverrides which is per-part.
  - TextureCache.GetOrUploadWithPaletteOverride: new entry point that
    composes the effective palette at decode time. Composite cache key
    is (surfaceId, origTexOverride, paletteHash) so entities with
    equivalent palette setups share the GL texture.
  - ComposePalette: ports ACViewer's IndexToColor overlay loop:
      for each subpalette sp:
          startIdx = sp.Offset * 8             // multiply back from wire
          count = sp.Length == 0 ? 2048 : sp.Length * 8   // sentinel
          for j in [0, count):
              composed[j + startIdx] = subPal.Colors[j + startIdx]
    Critical detail: copies from the SAME offset in the sub palette, not
    from [0]. Both base and sub are treated as full palettes sharing an
    index space.
  - StaticMeshRenderer.Draw: three-way switch on (entity.PaletteOverride,
    meshRef.SurfaceOverrides) picks the right TextureCache path:
      - Both → palette override (it handles origTex override internally)
      - Only tex override → GetOrUploadWithOrigTextureOverride
      - Neither → plain GetOrUpload
  - GameWindow.OnLiveEntitySpawned: builds PaletteOverride from
    spawn.BasePaletteId + spawn.SubPalettes when the server sent any.

Reference note: the user asked "but I mean THIS MUST BE IN WORLDBUILDER"
which was the right push. WorldBuilder is actually a dat VIEWER and its
ClothingTableBrowserViewModel is a 10-line stub — it doesn't apply
palette overlays because it doesn't need to. The actual algorithm lives
in ACViewer (a MonoGame character viewer), which I should have checked
earlier. CLAUDE.md updated with a standing rule: always cross-reference
all four of references/ACE, ACViewer, WorldBuilder, Chorizite.ACProtocol,
plus holtburger. A single reference can be misleading; the intersection
is usually the truth.

Tests: 77 core + 83 net = 160, all green.

b69d776179 feat(net+app): TextureChanges applied via Surface→OrigTex resolution (Phase 5a)
Finishes the TextureChange half of ObjDesc. Characters' clothing now
renders with correct per-part textures (user-verified "looks good"
after previous "partial coverage" / "wrong clothes"). The Nullified
Statue still looks like a flesh-colored drudge because the statue's
color comes from SubPalettes (palette-indexed texture recoloring),
which is the remaining major Phase 5 piece.

The first attempt at TextureChange application was silently broken by
an ID-type mismatch: the server encodes OldTexture/NewTexture as
SurfaceTexture (0x05XXXXXX) ids, but my sub-meshes are keyed by
Surface (0x08XXXXXX) ids. The override dict was keyed by one type
and looked up by the other, so TryGetValue never hit and no override
actually applied.

Diagnosed via Phase 1 systematic debugging with resolve-level logging:

  live: spawn +Acdream texChanges=20
  live:   texChange part=0 old=0x05000BB0 new=0x0500025D
  ...
  live:   resolve part=0 surface=0x08000519 origTex=0x05000BB0 [MATCH]
  live:   resolve part=0 surface=0x0800051C origTex=0x05000CBE [MATCH]
  ... 10/10 lines [MATCH]

The [MATCH] lines proved the server's OldTexture IS reachable via a
Surface→OrigTextureId lookup, just needed keying by the right value.

Fix:
  - TextureCache.GetOrUploadWithOrigTextureOverride(surfaceId, origTexOverride):
    loads the base Surface dat for its color/flags/palette, but
    substitutes the override SurfaceTexture id in the decode chain.
    Caches under a (surfaceId, origTexOverride) composite key.
  - MeshRef.SurfaceOverrides is now Dictionary<uint, uint> keyed by
    Surface id, value = replacement OrigTextureId. Null means no
    overrides.
  - GameWindow.OnLiveEntitySpawned now does TWO passes when texture
    changes are present:
      1. Group the raw server changes by PartIndex into (oldOrigTex →
         newOrigTex) dicts
      2. For each affected part's post-animPartChange GfxObj, iterate
         its Surfaces list, resolve each Surface → OrigTextureId, and
         if that matches a raw change's oldOrigTex, write an entry
         Surface id → newOrigTex into the final override map
  - StaticMeshRenderer.Draw: when sub-mesh surface id has an override,
    call GetOrUploadWithOrigTextureOverride instead of GetOrUpload.

Verified live: +Acdream's clothing renders correctly, NPCs are
"much better" (characters previously naked are now dressed). Statue
has the full mechanical pipeline working (resolve diagnostic shows
2/2 Surfaces [MATCH] for the statue's override dict) but its visible
color comes from the separate SubPalette overlay that isn't wired yet.

Also added a statue-targeted diagnostic block that dumps its full
ObjDesc contents (texChanges + subPalettes + animPartChanges) by
name match, which is how I traced the Nullified Statue of a Drudge's
specific ObjDesc. Lives under `if (isStatue && ...)` so normal logins
aren't spammed.

Cross-referenced against two new references this session:
  * references/Chorizite.ACProtocol (cloned from github.com/Chorizite/
    Chorizite.ACProtocol.git on user's suggestion) — confirms the
    ObjDesc field order and PackedDword-of-known-type convention.
  * references/WorldBuilder/... (already in repo) — confirms the
    Surface→OrigTexture→SurfaceTexture→RenderSurface chain and the
    P8/INDEX16 palette decode path.

Tests: 77 core + 83 net = 160, all green.

9970811dc3 feat(core): procedural scenery from Region.SceneInfo (Phase 2c)
Adds SceneryGenerator.Generate which walks Region.TerrainInfo.TerrainTypes
+ Region.SceneInfo.SceneTypes for each landblock vertex, selects a scene
using the AC client's pseudo-random LCG hash of global cell coordinates,
then rolls each ObjectDesc's frequency, computes a displaced cell-local
position, random scale, and random rotation — the exact algorithm
ACViewer ports from the retail AC client's get_land_scenes().

Phase 2 rendered 239 explicit Stab+Building entities on the 3x3 Holtburg
grid but was missing every procedurally-placed tree, bush, rock, fence,
and small decoration because these are not stored as LandBlockInfo entries.
This adds 419 scenery entities across the same 9 landblocks, bringing the
total to 658.

Integration in GameWindow.OnLoad: after the existing Stab/Building
hydration loop, iterate each landblock's scenery spawns, resolve each
to a GfxObj or Setup via the same mesh pipeline, bake the random scale
into each MeshRef's PartTransform so the static mesh renderer doesn't
need a scale field on WorldEntity, and sample the landblock heightmap
bilinearly for the ground Z (simpler than ACViewer's find_terrain_poly
slope-aware placement).

Deliberate deferrals for first pass:
- No slope-based rejection (obj.MinSlope/MaxSlope). Trees may end up on
  cliffs they shouldn't be on.
- No road-overlap rejection. Scenery may spawn in roads.
- No building-overlap rejection. Scenery may clip buildings.
- No WeenieObj handling (those are dynamic spawns, not static scenery).

All three filters will be added in a follow-up phase when we have the
walkable-polygon infrastructure they need.

Build clean, 48 tests still pass, smoke verified: "scenery: spawned 419
entities across 9 landblocks", process runs without exceptions.

Addresses the user visual feedback after Phase 2b: "some extra details
are missing, like a tree and the statue on top of the foundry". The tree
issue is now fixed (419 trees/bushes/rocks/etc placed). The foundry
statue may still be missing if it's a hierarchical Setup part (Phase 2a's
SetupMesh.Flatten intentionally doesn't walk ParentIndex) — that's a
separate fix if smoke verification shows it's still missing.
