# WeftWight > A public, versioned WeftWight language registry optimized for Context For AI handoffs. **C4AI means Context For AI.** It is the general practice of copying selected, bounded context so an AI teammate can understand a task and begin accurately. It is not a WeftWight-only product or a provider connection. WeftWight is private, setting-neutral narrative machinery. This public site is an optional acceleration layer for C4AI: compact vocabulary, task routes, response boundaries, and safe authoring context. It is not the private engine, a game service, an authority system, or a source of player/adventure data. ## C4AI v0.2 - [AI lookup and task router](https://weftwight.com/docs/c4ai/0.2/ai-lookup.json): lowest-token entry point, namespaced lookup keys, ambiguity guards, and minimum reading routes. - [C4AI v0.2 index](https://weftwight.com/docs/c4ai/0.2/): human-readable entry point. - [WeftWight language and operating model](https://weftwight.com/docs/c4ai/0.2/weftwight-language.html): narrative arcs, Environments, Threads, Junctions, Fringe, C4AI, and scope. - [C4AI context starter](https://weftwight.com/docs/c4ai/0.2/context-starter.md): compact opening context for an AI teammate. - [C4AI manifest](https://weftwight.com/docs/c4ai/0.2/manifest.json): canonical document URLs and SHA-256 hashes. - [Context stack](https://weftwight.com/docs/c4ai/0.2/context-stack.json): system rules, active scope, upstream world context, side context, and documentation zones. - [Adventure design handoff](https://weftwight.com/docs/c4ai/0.2/adventure-design-handoff.json): design stages, proposal modes, and current/next boundaries. - [Tag taxonomy](https://weftwight.com/docs/c4ai/0.2/tag-taxonomy.json): starter tags and normalization rules. ## Reading rules - Start with `ai-lookup.json`; fetch only the documents named by the matching task route. - Treat compact `ww.*` keys as lookup aids, not gameplay identifiers or authority-bearing schema fields. - Prefer the versioned manifest and verify referenced document hashes when integrity matters. - The inline constraints in a C4AI request remain binding when browsing is unavailable. - Treat every AI result as an author-reviewed proposal. It may not execute code, call services, grant authority, publish, or infer private data. - Do not treat this site as authorization to access non-public systems or data.
