wgt01: add STATUS.md build log + loose-file toolset testing note

STATUS.md: what the generator kit produces, the pipeline commands, what's
verified (build/export/set), first-pass caveats, git state, and next passes.

AGENTS.md §6.3: test tilesets without packing a .hak by dropping loose .set/
.mdl/.wok into ~/Documents/Neverwinter Nights/development/ (toolset reads it).

+### 6.3 Testing without a `.hak` (loose files)
+
+For iteration, skip packing: the toolset reads loose resources from
+**`~/Documents/Neverwinter Nights/development/`**. Copy the `.set` + all `.mdl` +
+`.wok` (and, once authored, the `.itp`/minimaps/2das) there, then create a small
+area with the tileset and walk-test. Much faster than pack→reload; pack the
+`.hak` only once the set is validated.

+
+Progress log for the **Westgate Urban Foundation MVP** tileset (prefix `twu01`).
+Spec: [KICKOFF.md](KICKOFF.md). How NWN needs things shaped: [../AGENTS.md](../AGENTS.md).
+
+_Last updated: 2026-07-04._
+
+---
+
+## What exists — the generator kit (`generator/`)
+
+One source of truth (`tiles.py`) feeds four tools; the two NWN emitters need no
+Blender, so they're directly testable.
+
+| File | Role | Needs Blender? |
+|---|---|---|
+| `tiles.py` | **Single source of truth**: 40-tile table, 12 materials, the 12×12 test map, and all pure derivations (paint / height / walkmesh quads / `.set` corner+crosser mapping). `PREFIX=twu01`. | no |
+| `build.py` | Builds `westgate_urban_foundation_mvp.blend` — 40 tile collections (`VIS_`/`WOK_`/`BLOCK_` + edge custom props), `TILE_EDGE_METADATA` text block, `PREVIEW_tile_library_grid`, `PREVIEW_12x12_test_district`. | yes (4.0.2) |
+| `export_mdl.py` | Real NWN export via **Neverblender** → 40 `.mdl` + 40 `.wok` (AuroraBase `tile`/`dummy`, `trimesh`, one `aabb` walkmesh; correct surfacemats). | yes + addon |
+| `make_wok.py` | Pure-Python ASCII `.wok` emitter (verts+faces+surfacemat+AABB tree). Fallback when Neverblender absent — format **validated identical** to Neverblender's output. | no |
+| `make_set.py` | First-pass `twu01.set` (INI, **CRLF**) from the tile grammar. | no |
+
+`flake.nix` exposes these as apps + a dev shell (pinned **Blender 4.0.2**,
+`neverwinter-nim`, `cleanmodels`).
+
+## Pipeline (commands)
+
+```sh
+cd wgt01
+nix run .#build  -- out.blend          # 1. Blender tile library
+nix run .#export -- out.blend mdl/     # 2. real .mdl + .wok (Neverblender)
+nix run .#set    -- twu01.set          # 3. first-pass .set (CRLF)
+# nix run .#wok  -- wok/               # ASCII .wok fallback only (export_mdl preferred)
+```
+
+## Verified (2026-07-04)
+
+- **build**: 40 collections, 144/144 district cells placed, 0 skipped, 12 materials.
+- **export**: 40 `.mdl` + 40 `.wok`. Surfacemats correct — CP1 all `wok_Stone`(4),
+  CN1 all `wok_Nonwalk`(7), BR_1/CE_S walkable+blocker mixed. `.mdl` has
+  `newmodel twu01_cp1`, `classification TILE`, AuroraBase name == resref.
+- **Neverblender**: enabled + working **headless** via the flake's
+  `blender-4.0.2 --background`, reading `~/.config/blender/4.0` (same config as
+  the interactive session). Surfacemat = walkmesh face **material slot index**
+  after `nvb_utils.create_wok_materials(mesh)` — not the material name.
+- **`.set`**: CRLF (1224/1224 lines), 40 tiles, 3 terrains (`cobble`/`raised`/
+  `canal`), 2 crossers (`ramp`/`canal_edge`). Corners/heights derive from each
+  tile's N/E/S/W edge grammar; ramp N-corners → height 1, canal edges →
+  `canal_edge` crosser, non-walkable tiles → `PathNode=N`.
+
+## Testing in the toolset — no `.hak` needed
+
+The toolset reads loose files from **`~/Documents/Neverwinter Nights/development/`**
+(confirmed present). Drop the build outputs there and they're picked up directly:
+
+```sh
+DEV="$HOME/Documents/Neverwinter Nights/development"
+cp mdl/twu01_*.mdl mdl/twu01_*.wok "$DEV"/
+cp twu01.set "$DEV"/
+```
+
+Then in the toolset: create a small area using the `twu01` tileset, place tiles,
+walk-test pathing/heights. (Packing a `.hak` with `nwn_erf` is deferred until the
+set is validated.)
+
+## First-pass caveats — tune before shipping
+
+- **PathNode** is a placeholder (`A` walkable / `N` non-walkable) — verify creature
+  routing per tile shape in the toolset; real pathnode letters matter.
+- **No `.itp` palette** yet — tiles may not appear in the toolset palette tree
+  until one is authored (GFF; `neverwinter-nim`'s `nwn_gff`). The `.set` still
+  loads for area creation.
+- **No minimaps** — `ImageMap2D` refs exist in the `.set` but the `.tga`s don't
+  (skipped by decision; Westgate doesn't use them).
+- **Substitutions**: `RA_C` = straight-ramp geometry; `STA` = smooth ramp WOK
+  proxy over stepped visual; `SW_C/T/X/E` share the straight-sidewalk visual.
+- `MAT_void_black` is defined but currently unpainted (11/12 materials realised).
+- Corner terrain is a heuristic from edges — hand-tune adjacency in the toolset.
+
+## Git
+
+Branch **`wgt01-tileset-kit`** (`main` still unborn — `git branch -f main
+wgt01-tileset-kit` to promote). Commits:
+- `60af184` — build guide + 40-tile generator kit
+- `1284f15` — real `.mdl`/`.wok` export via Neverblender
+
+## Next passes
+
+1. Author `twu01palstd.itp` palette so tiles show in the toolset palette tree.
+2. (optional) A `dev-install` flake app to copy build outputs into `development/`.
+3. Walk-test in the toolset → tune PathNodes, crossers, corner terrains.
+4. Pack `.hak` (`nwn_erf`) once validated.
