 Per-type constructors live on the type, not as top-level re-exports. Use `Message.system(...)`, `Message.user(...)`, `Message.assistant(...)`, `Message.tool(...)`, `LanguageModel.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`, and `LLM.generateObject`. Use `LLMRequest.update(...)` when deriving canonical request data; do not add a duplicate `LLM.updateRequest(...)` path. Two ways to construct the same thing is one too many.

- Prefer forward compatibility for provider-defined options that OpenCode only passes through. For pass-through string enums, expose known values for autocomplete while accepting future values with `Known | (string & {})`, and accept any string at runtime. Closed literals are appropriate when OpenCode branches on a value, transforms its associated structure, or otherwise cannot correctly handle an unknown variant. New options whose shape or behavior requires implementation remain unsupported until they are handled; do not blindly forward unknown structures.
+- 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.
 - Order reasoning-effort values from lowest to highest: `none`, `minimal`, `low`, `medium`, `high`, `xhigh`, `max`. Provider-specific subsets follow the same relative order in types, schemas, option lists, and tests.

 Run `LLMClient.stream(request)` instead of `generate` when you want incremental `LLMEvent`s. The event stream is provider-neutral — same shape across OpenAI Chat, OpenAI Responses, Anthropic Messages, Gemini, Bedrock Converse, and any OpenAI-compatible deployment.

-## Experimental evaluation
-
-Evaluation models compare shared state with typed choice, score, and boolean questions. The API is
-isolated under an experimental entrypoint and provider namespace while the contract evolves:
-
-```ts
-import { Effect } from "effect"
-import { Evaluation, EvaluationClient } from "@opencode/ai/experimental"
-import { TypeSafeAI } from "@opencode/ai/providers"
-
-const model = TypeSafeAI.configure().experimental.evaluation("jev-latest")
-
-const program = Evaluation.evaluate({
-  model,
-  state: "I was charged twice. Please refund the duplicate payment.",
-  questions: {
-    department: {
-      type: "choice",
-      instructions: "Which team should handle this?",
-      criteria: { billing: "Payments and refunds", technical: "Bugs and outages" },
-    },
-    urgency: {
-      type: "score",
-      instructions: "How urgent is this?",
-      criteria: ["Can wait", "Needs prompt attention", "Blocking revenue"],
-    },
-    refund: { type: "boolean", instructions: "Is the customer asking for a refund?" },
-  },
-})
-
-const response = await Effect.runPromise(program.pipe(Effect.provide(EvaluationClient.fetchLayer)))
-
-console.log(response.answers.department.choice)
-console.log(response.answers.refund.probability)
-```
-
-`TypeSafeAI` reads `TYPESAFE_API_KEY`. `OpenCodeZen` exposes the same selector and reads
-`OPENCODE_API_KEY`. The common API uses `boolean`; System One routes lower it to native `noul`.
-Choice and score confidence plus score legends remain available in provider metadata, and the
-provider's rounded probabilities are returned unchanged.
