+# ADR-0015: NPC model variety sourcing
+
+- **Status:** Accepted (post-0.10.0 planning)
+- **Date:** 2026-11-03
+
+## Context
+
+The library has eight skinned characters, and role/seed selection reuses them
+across the three venues. Crowds therefore repeat the same faces, builds and
+outfits. The existing contract is strict: `npc_base` mesh node, 13 named bones at
+fixed rest positions, five tint slots, front on Blender −Y and an 8,000
+triangle/vertex budget.
+
+A review compared free/open-source sources against that contract. Quaternius
+Ultimate Modular (CC0), Kenney Blocky Characters (CC0), Khronos CesiumMan and
+RiggedFigure (CC BY 4.0) and the MakeHuman base mesh (CC0) were imported and
+measured. None was a drop-in; the full results are in
+[`docs/npc-model-sourcing.md`](../npc-model-sourcing.md).
+
+## Decision
+
+1. **Ship only CC0, or CC BY with recorded attribution.** No service asset whose
+   terms restrict redistribution may be used.
+2. **Extend the project-owned procedural generator as the primary path** for
+   shipped NPC variety. The first target is four crowd-variety looks, bringing
+   the library to twelve characters.
+3. **Keep Quaternius as a reviewed reference/prototype, not a shipped base.** A
+   contract retarget is a no-go because the source is a T-pose 62-bone realistic
+   rig with substantially different proportions from the arm-down 13-bone
+   contract. A future external-rig path would need its own ADR covering its
+   skeleton, animation source and per-model gear offsets.
+4. **MakeHuman is deferred to a separate local development pipeline.** Its CC0
+   base mesh can be decimated into budget, but it needs retopology, a custom rig
+   and project-owned clothing before it is usable. It must not become a CI or
+   build dependency.
+5. **Commit research previews with attribution.** CC-BY preview images are
+   development-only and are not bundled with the game or its release packages.
+
+## Consequences
+
+### Positive
+
+- The shipped library keeps one art direction, one skeleton and one audit gate.
+- Crowd variety lands without a new runtime dependency or a second animation
+  system.
+- The licence position is simple: project-owned assets plus explicit CC-BY
+  attribution where a preview or future asset requires it.
+- The Quaternius evaluation removes a tempting but high-risk retarget from the
+  critical path.
+
+### Negative
+
+- Procedural variation is still limited by the existing face and clothing
+  vocabulary; four variants do not provide full age/body diversity.
+- Quaternius' animation set remains unused unless a second rig path is approved.
+- MakeHuman body-shape diversity is postponed.
+- External previews add a small documentation footprint that must stay out of
+  release packages.
+
+## Alternatives considered
+
+- **Retarget Quaternius onto the `npc_base` contract.** Rejected for now:
+  welding brings the geometry inside budget, but the rest pose and body
+  proportions differ enough that a contract rebuild would either distort the
+  model or require a full proportion warp.
+- **Use Quaternius' own rig and animations directly.** Deferred: attractive
+  animation quality, but it adds a second skeleton/animation path and per-model
+  gear offsets to `NpcAvatar`.
+- **Use MakeHuman as the primary body source.** Rejected for this milestone: high
+  polygon count, no rig in the base mesh and a separate authoring dependency.
+- **Use Mixamo or Ready Player Me.** Rejected: service terms are not a simple
+  free/open-source redistribution basis for shipped meshes.

+
+### Quaternius prototype
+
+The prototype used `Casual_Hoodie.glb`:
+
+- **Geometry budget is not the blocker.** Imported: 12,518 vertices / 6,206
+  triangles. After welding seam splits: 3,199 vertices / 6,206 triangles. After
+  a 0.75 decimate: 2,423 vertices / 4,654 triangles, comfortably inside the
+  library budget.
+- **Animation quality is attractive.** The imported Idle and Walk clips read
+  well at game distance, and the model brings 24 animations.
+- **The contract rest pose is the blocker.** The source is a T-pose 62-bone rig
+  with realistic proportions: upper leg starts near 0.96 m, arm span is about
+  1.68 m, and the shoulder joint sits near x = 0.153 m. The project contract is
+  an arm-down 13-bone rig with a hip near 0.62 m, a shoulder near x = 0.27 m and
+  a hand near z = 0.78 m. Rebuilding the contract armature around this mesh would
+  either distort the body substantially or require a full proportion warp.
+- **Decision:** do not retarget Quaternius to the contract now. Keep it as a
+  silhouette/style reference and, if a second rig path is ever wanted, prototype
+  it as its own animation path (its own skeleton, AnimationPlayer clips and
+  per-model gear offsets) rather than forcing it into `npc_base`. That is a
+  separate architecture decision, not an asset conversion.
+
+Preview: [`blender_previews/sheet_npc_sources_research.jpg`](blender_previews/sheet_npc_sources_research.jpg).
+
+### Generator crowd prototype
+
+Four proposed crowd specs were built with the existing generator in a temporary
+output directory. All four audit clean and stay inside the character budget:
+
+| Prototype | Look | Tris / verts | Gear |
+| --- | --- | --- | --- |
+| `npc_crowd_a` | slim, bun, sunglasses | 4,644 / 4,356 | sunglasses |
+| `npc_crowd_b` | broad, bald, beard | 4,550 / 4,453 | shoulder bag |
+| `npc_crowd_c` | average, short hair, long coat | 5,118 / 5,086 | umbrella |
+| `npc_crowd_d` | slim, short hair, hood up | 5,258 / 4,907 | cup |
+
+They vary build, head silhouette, hair/beard and outer layer while keeping the
+existing face language. They are **not in the shipped catalogue**; production
+integration belongs to milestone 0.11.4 after the 0.10.0 release candidate.
+
+Preview: [`blender_previews/sheet_npc_crowd_prototypes.jpg`](blender_previews/sheet_npc_crowd_prototypes.jpg).
+
+### MakeHuman local-pipeline evaluation
+
+The CC0 base mesh is 19,158 vertices / 18,486 polygons (36,972 triangles after
+triangulation), with 21,334 UV coordinates but no normals, material groups or
+rig. Scaling it to 1.82 m and decimating to 0.35 produced 3,780 vertices / 6,468
+triangles, which fits the geometry budget but is a collapse-decimation result,
+not production topology.
+
+MakeHuman is therefore **feasible only as a separate local body-shape pipeline**:
+generate a small set of bodies locally with MPFB/MakeHuman, export the CC0
+meshes, decimate or retopologise them, build the contract rig and add
+project-owned heads, hands, clothing and gear. It must not become a CI or build
+dependency, and only the final CC0-derived assets with recorded provenance may be
+committed. This is deferred; it is not part of the 0.11.0 crowd-variety work.

-## Review questions

-The project owner should answer these before the 0.11.0 work starts:
+The project owner answered the review questions on 2026-11-03:
 
-1. Are third-party CC0 characters acceptable in shipped game assets, or should
+| Question | Answer |
-   the library stay entirely project-owned?

-2. If yes, is the Quaternius CC0 pack acceptable as a silhouette/outfit donor
+| Are third-party CC0 characters acceptable? | Yes. |
-   with a rebuilt project-style head and hands?
+| Which direction? | Prototype Quaternius and extend the procedural generator. |
-3. Which four role families would benefit most from a new look: everyday

-   guests, workwear, responders, or crowd variety?
+| Should MakeHuman be pursued? | Evaluate it for a later, separate local development pipeline. |
-4. Is the MakeHuman/MPFB body-shape pipeline worth a later investment, or is

-5. Should the preview sheet be committed as a review artefact (with attribution

-Until those answers exist, the safe default is **Option A: extend the owned
-procedural generator and keep external models as references only.**
