# Script Effect Contracts

This generated snapshot is derived from the canonical Script IR node catalog and the Script Effect Contract builder. It describes host effects, runtime pending-op receipt mappings, and the typed gameplay state scopes projected to AI, MCP, SDK, frontend, and Platform Catalog surfaces.

Contract version: `script-effect-contract.v1`.
Typed gameplay state version: `typed-gameplay-state.v1`.
Catalog hash: `sha256:cb70a0c39411cee3f013d8366510880a50cbd937a3ef2040ec68be11e2a10240`.
Host effect contracts: `112`.
Runtime pending-op mappings: `43`.
Effect tags: `pure`, `readWorld`, `writeWorld`, `readState`, `writeState`, `emitEvent`, `spawnEntity`, `despawnEntity`, `physicsCommand`, `uiEffect`, `audioEffect`, `platformRequest`, `networked`, `durable`, `nonRollbackable`, `requiresAuthority`.
Typed gameplay state scopes: `entity`, `script_instance`, `room`, `match`, `player`, `team`, `global`, `persisted_player`, `persisted_project`.

## Projection Rules

- Canonical Script IR is the only source for per-script effect contracts.
- Semantic Patch is the normal authoring path for creator/AI gameplay behavior.
- Generated TypeScript and visual graph layouts are projections, not contract authority.
- Runtime draining refuses pending ops that cannot be matched to a declared script effect contract.
