-### 2026-11-05 — NPC plan pivot and tmp cleanup
-
-**What changed:** the NPC character direction was rewritten around the researched CC0
-Quaternius character. ADR-0017 supersedes the generator-first decision in ADR-0015. `PLAN.md`,
-`TODO.md`, `MEMORY.md`, `README.md`, `CREDITS.md`, the architecture/asset/review docs and the
-docs index now point to the Quaternius base. The old MPFB/MakeHuman body tracks were closed and
-their plans removed from `TODO.md`; the MakeHuman head and procedural `npc_base` remain tested
-fallbacks only.
-
-**Cleanup:** `tmp/` was reduced from ~2.9 GB to 4.7 MB. Removed the MPFB/MakeHuman scripts,
-review renders, map scratch output and logs. Kept only the three researched Quaternius GLBs,
-the Quaternius mirror HTML/README/licence, `prototype_quaternius.py`, and a local
-`tmp/npc-research/quaternius/README.md` with hashes and re-download links. Do not delete that
-folder while the migration is active.
-
-**Implementation status:** planning and documentation only. No character GLB, code, manifest,
-AO map or test was changed. The 12 shipped NPC GLBs still use the old procedural bodies.
-
-**Next task (start here):** `TODO.md` → *Quaternius NPC base migration* → §1 Intake and
-canonical base. First concrete step: inventory the four meshes, 62 joints, 24 clips and
-material names in each of the three GLBs, then build a welded, grounded, animation-free
-`quaternius_base.glb` at 1.81 m with front on Blender −Y.
-
-**Main risk:** the source is a 62-joint T-pose with realistic proportions (research measured
-~0.96 m hip, ~1.68 m arm span, ~0.153 m shoulder offset), while the runtime contract is an
-arm-down 13-core rig with a 0.62 m hip and 0.27 m wrist targets. The Stage 1 proportion warp is
-the make-or-break step. Judge the Quaternius result directly; do not reuse the old MPFB arm
-warp. If the warp fails the silhouette/gear gate, stop and write the Stage 2 62-joint ADR.
-
-**Key paths:**
-- Source GLBs: `tmp/npc-research/quaternius/{Casual,Casual_Hoodie,Worker}.glb`
-- Source hashes and inventory: `docs/npc-model-sourcing.md`
-- Decision: `docs/adr/0017-quaternius-npc-base.md`
-- Contract: `docs/architecture.md#character-and-gear-asset-contract`
-- Runtime selector/fallback: `src/game/npc_avatar.gd`, `assets/models/blender/`
-- Current library builder/fallback: `tools/blender_assets.py`, `tools/npc_pipeline.py`,
-  `assets/models/generated/npc_base.glb`
-
-**Useful checks:** `python3 tools/check_docs.py`; `pytest -q tools/tests`;
-`python3 tools/blender_assets.py audit|fit`; Blender headless:
-`flatpak run org.blender.Blender --background --python "$PWD/tools/blender_assets.py" -- inspect --category npc --file "$PWD/<file>.glb"`.
-This session ran `check_docs` and `git diff --check` after the doc rewrite; Python tests were
-last green at 167/167. Godot tests were not rerun because no runtime file changed.
-
-**Commit:** `2c90743 Rewrite NPC plans around the Quaternius base`. Working tree clean.
