Seven independently-usable modules on the six-lever contract with name-keyed data registries (zero-code content): movement (grid/free/tween, 4/8-axis, veto + interact), inventory + equipment (stat bonuses via the gameplay modifier stack), crafting, event-driven quests + flags, an Ink/Yarn dialog graph, Sokoban pushables + a switch/plate/gate signal graph, and over-time status effects through the Combat pipeline. Reuses ludic.gameplay Stats/Combat. Deterministic. 21-check example, in the suite (103 passed, 0 failed). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# crafting.ludic — RPG Module C: a data-driven crafting registry (#59).

# Recipes are content, not code: register with Craft.recipe + Craft.ingredient, so a
|
|
# game or mod adds crafting with zero code. Craft.make consumes ingredients from the
|
|
# ludic.rpg Inventory and yields the output; every step is a veto-able event.
