This generated snapshot is derived from packages/world-build-contract. It is the Milestone 4B contract projection for prompt-to-world build contracts, renderer/material capabilities, deterministic demo recipes, QA eval receipts, and execution timeline coordinates.

Acceptance Policy

world.build.from_prompt is the canonical action for prompt-to-world build execution.
world.build.from_spatial_asset is the canonical action for turning imported/generated spatial assets into executable worlds.
Playable spatial world acceptance requires collision proxy, nav/query proxy, semantic anchor, and playability.accepted receipts; renderability alone is not playable proof.
Accepted build proof requires semantic contract proof, Project Graph validation, visible unsupported requirements, passing QA receipts, and a timeline receipt.
Generated assets may iterate through placeholders, but accepted final proof only permits terminal_success, substituted, or degraded asset receipts.
Renderer/material choices must reference cataloged capability ids; raw shader/pass fields such as shaderSource, fragmentShader, vertexShader, wgsl, glsl, renderPassCode, and customPassSource are forbidden.
Workbench product claims use explicit terminal states and proof tri-state; missing proof is not_run, not pass.

Workbench Semantic Product Spec

Normal Workbench AI build paths must produce a prompt-specific Semantic Product Spec before lowering to canonical world-build operations. Deterministic fixture defaults are only permitted in explicit test/demo fixture paths.

Field	Meaning
`prompt`	Original user prompt used for traceability and prompt-specific hashing.
`intent`	Workbench product claim intent such as `visual_world_build` or `playable_game_factory`.
`genreOrWorldType`	Planner-selected semantic product category for this prompt.
`targetExperience`	Short user-facing experience goal that all projections derive from.
`visualStyle`	Mood, palette, and density for renderer/material planning.
`regions`	Named semantic areas such as districts, lanes, routes, water, or parks.
`entityClasses`	Prompt-specific entity classes that expand into semantic batch items.
`gameplayLoops`	Gameplay loop descriptions and proof requirements for playable builds.
`scriptBehaviors`	Script Semantic Patch behavior intents; not raw Script IR or source.
`typedState`	Typed score/win/runtime state contract for playable builds.
`uiHud`	HUD bindings backed by typed state, not renderer-only claims.
`camera`	Semantic camera mode, framing, transform, and fov.
`lighting`	Semantic lighting rig and atmosphere.
`materials`	Catalog capability ids and material direction; raw shader/pass fields are forbidden.
`proofPlan`	Required visual/runtime/factory proof lanes.
`acceptanceRubric`	Planner acceptance criteria that product-claim proof must satisfy.
`budget`	Planner budget for provider calls, cost, and child workers.
