Rename the registry vocabulary from capability classification to model controls (ControlsFor/Preview) and add llm.EffectiveControls, attached to responses and streams by Anthropic, Google, OpenAI, and Grok so clamped effort, emulated budgets, and dropped temperature are visible on llm.Usage without wiring a logger. Aggregated usage keeps controls only while requests agree, setting Usage.ControlsMixed otherwise.

Document the MaxTokens assumption used by the preview.
The preview substitutes DefaultMaxTokens when the caller omits MaxTokens. The real request path uses the provider instance value from applyRequestConfig (p.maxTokens), which callers can change with provider options. clampThinkingBudget derives the effective budget from MaxTokens, so a provider built with a smaller maxTokens produces a different budget than the preview reports.
Add a short comment that states this assumption so the published preview contract is explicit.

Align ControlApplied with the resolved thinking state.
When ThinkingTypeEnabled and ReasoningEffortNone produce a zero thinking budget, plan.Effective.Thinking becomes disabled, but this branch reports ControlApplied because thinking is non-nil. Report ControlOmitted with Adjusted: true and the disabling reason when hasBudget && budget == 0.

Restrict capabilities for non-reasoning Grok variants.
modelControlsFor resolves both non-reasoning IDs to the grok-4 entry and copies its full grokBelowMax ladder into Reasoning.NativeEfforts. The catalog directs these exact IDs to use reasoning effort none. Give each non-reasoning variant an exact capability entry so callers cannot select unsupported reasoning efforts.

What this does
Different model APIs accept different controls for reasoning and temperature, and they often interpret the same setting differently. Dive already handles those differences when it builds requests. Until now, an application that wanted to show valid settings or validate a configuration had to copy those provider rules and keep them in sync.
This PR makes that behavior available directly from Dive, without sending a network request.
Applications can now ask three practical questions:
Providers()— Which provider packages have registered model information in this program?ClassificationFor(provider, model)— Which controls are supported by this exact model from the provider catalog, and on which API was that information verified?Explain(provider, config)— What will Dive do with these requested settings before it builds the provider request?For a concrete configuration,
Explaincan report that Dive will:The result also includes the final, provider-neutral settings that request construction will use.
How it stays accurate
Explainuses the same provider code that real request construction uses. It is not a second compatibility table with a separate set of rules.Published support is intentionally limited to exact model IDs in each provider catalog. A future model, fine-tune, gateway model, or custom deployment does not inherit a published guarantee just because its name shares a prefix with a known model.
Verification is tied to the API that was actually tested. For example, evidence from Vertex AI is not presented as evidence for the public Gemini API.
This PR includes model information for OpenAI, Grok, Anthropic, and Google.
What does not change
This is an additive inspection API. Existing request behavior remains the same:
The PR also includes the reviewed design document, a usage guide, a documentation index entry, a changelog entry, and tests that confirm the explanation matches real request construction.
