+# RuneWaker dungeon maps
+
+The RuneWaker minimap shows a cropped dungeon map centered on the live player
+marker. Press **M** or click the minimap to open the full map. The player marker
+and heading, entrance, and numbered encounters use the same coordinate projection
+in both views. The full map closes with **M**. The existing map keybind and minimap
+rotation preference apply to RuneWaker dungeons too.
+
+All 30 imported RuneWaker dungeon definitions have maps. Fifteen use calibrated
+minimap tiles from the extracted RuneWaker client. Fifteen use floorplans rendered
+from each dungeon's imported navigation mesh because matching client tiles are
+missing or cannot be aligned confidently. The floorplans still place live markers
+and encounters at their runtime coordinates. The UI labels a floorplan as such.
+
+## Reimporting
+
+Run `python scripts/runewaker-pipeline/import-maps.py` from the HealerMan root with
+Pillow and NumPy available. `RUNEWAKER_ROOT` can point to the extracted RuneWaker
+client; the default is `../Runewaker`. The importer reads DDS tiles under
+`Resource/texture/minimap`, the primary WDB placement in each dungeon's
+`import-metadata.json`, and the navigation GLB. It measures alignment between the
+tile artwork and navigation geometry, accepts client artwork at confidence 0.65
+or higher, and creates a navigation floorplan otherwise.
+
+The generated PNGs live at `public/assets/game/dungeons/<id>/maps/runewaker-map.png`.
+The runtime projection and source checksums live in
+`src/game/generated/runewakerDungeonMaps.generated.json`. The map loader rejects
+catalog entries when the dungeon map ID, coordinate transform, or visual checksum
+no longer matches the runtime definition. Reimport after changing those inputs.
+
+Run `npm run content:publish` after reimporting so downloadable dungeon packs
+contain their map PNGs, then `npm run build` to refresh the bundled app.
+
+## Verification
+
+Run `node node_modules/vitest/vitest.mjs run src/game/dungeonArtworkMap.test.ts src/ui/DungeonMapGraphic.test.ts src/ui/MapPanel.test.ts`.
+`node scripts/playtest-runewaker-maps.cjs` checks Forsaken Abbey in a browser,
+including its downloaded artwork, minimap, M-key full map, and marker projection.
+Screenshots are written to `artifacts/playtest/runewaker-maps/`.
