 Per-type constructors live on the type, not as top-level re-exports. Use `Message.system(...)`, `Message.user(...)`, `Message.assistant(...)`, `Message.tool(...)`, `Model.make(...)`, `ToolDefinition.make(...)`, `ToolCallPart.make(...)`, `ToolResultPart.make(...)`, `ToolChoice.make(...)`, `ToolChoice.named(...)`, `SystemPart.make(...)`, and `GenerationOptions.make(...)` directly. The top-level `LLM` namespace is reserved for request-shaped call APIs: `LLM.request`, `LLM.generate`, `LLM.stream`, `LLM.updateRequest`, and `LLM.generateObject`. Two ways to construct the same thing is one too many.

+- Keep provider-defined string enums forward-compatible. Expose known values for autocomplete while accepting future values with `Known | (string & {})`; use `Schema.String` at runtime unless rejecting unknown values is required for correctness.

-/**
- * Tutorial: split global services from context-specific services.
- *
- * Use this pattern when part of the app should be constructed once at the app edge,
- * while another part should be cached per request/project/workspace key.
- *
- * In this example:
- * - Npm.Service is the global service. It is not keyed by request context and should
- *   be provided once by the application runtime.
- * - ConfigService is context-specific. It is built from a RequestContext key and is
- *   cached by LayerMap for that key.
- * - ConfigServiceMap.layer owns the cache. Provide it once globally, then each
- *   request can provide ConfigServiceMap.get(context) to select the right instance.
- *
- * Lifetime model:
- * - ConfigServiceMap.layer has the app/global lifetime and depends on Npm.Service.
- * - ConfigServiceMap.get(context) has the request/context lifetime and provides
- *   ConfigService for exactly that context key.
- * - The cached ConfigService entry stays alive while something is using it. Once idle,
- *   it remains cached for idleTimeToLive, then its scope is finalized.
- * - invalidate(context) removes the cache entry for future lookups. Active users keep
- *   running on the old instance; the next lookup can create a fresh instance.
- *
- * Key model:
- * - Keys can be strings, structs, classes, arrays, etc.
- * - Prefer primitive or immutable keys. Effect uses Hash / Equal semantics for cache
- *   lookup, so mutating an object after it has been used as a key is a bug.
