+# Crafting without a map dependency
+
+This mod needs `items_base` and `ui_base`. It can be opened from a visual novel choice, a scene interactive or an RPG event. It does not depend on a game, tiles, stats or a battle core.
+
+1. Define ordinary `item` entities for materials and products.
+2. Define a recipe (`Kind: recipe`).
+3. List it in a station (`Kind: craft_station`).
+4. Run `action craft.open station=my_game/bench` from any scenario.
+
+```json
+{
+  "Kind": "recipe",
+  "Items": [{
+    "Id": "my_game/salve",
+    "Name": "my_game/recipe/salve/name",
+    "Description": "my_game/recipe/salve/desc",
+    "Time": 5,
+    "Input": [{"Id": "my_game/herb", "Count": 2}],
+    "Output": [{"Id": "my_game/salve", "Count": 1}]
+  }]
+}
+```
+
+```json
+{
+  "Kind": "craft_station",
+  "Items": [{
+    "Id": "my_game/bench",
+    "Name": "my_game/station/name",
+    "Recipes": ["my_game/salve"]
+  }]
+}
+```
+
+Names and descriptions are locale keys. Add them to your mod's `locale/ru.properties` and `locale/en.properties`. The Data Editor discovers both kinds from `schemas/crafting.json`; the command palette knows `craft.open` and validates the station reference. No C# is needed to add recipes or stations.
+
+The window shows materials held/needed, products and live availability. Esc closes it. The shared overlay host blocks walking while it is open. A successful craft advances the game clock by `Time` minutes. Ingredients and products use the existing items save slot; there is no second crafting inventory or separate save format.
+
+All raw ingredients and outputs must resolve, counts must be positive and totals must fit in an integer. Duplicate ingredient rows count together. A refused craft changes no stack. This deliberately does not use RecipeFactory's tolerant display resolution, which can omit unknown ingredients.
+
+`CraftLedger` exposes batch arithmetic for other interfaces. `CraftPanel` rebinds its inventory on show after a new game or load. The station is an explicit recipe list; discovery/unlock rules belong to the game's scenarios (offer another station after a quest or flag).
+
+Run `--run-tests --mod=crafting` for ledger and JSON round-trip tests. RPG Plus's `woodland` and `woodland_pact` suites exercise the window, quests, real victory loot, crafted equipment and save/load together.
