Patch Changes

• fc1e19e: fix: limit jsonl rows to 64mb during batch result downloads

• 99bdcd2: Replace the OpenAI structured-output wrapper for decide with the native Decisions API. Only gpt-6-luna is currently supported by this endpoint; other Responses models no longer work with openai.decisionModel() or its deprecated evaluationModel() alias.

  Responses API options, such as reasoningEffort, are no longer applied and produce unsupported-option warnings. The Decisions API supports providerOptions.openai.safetyIdentifier. Native token usage and confidence values are preserved, and per-question refusals fail the decision call.

• 268225c: feat(provider): add a portable max reasoning level with native provider mappings, compatibility coercions, and budget-based fallback support.

  Compatibility notes:

  • TypeScript source compatibility: Adding max widens LanguageModelV4CallOptions['reasoning'] and the derived ReasoningLevel type. Third-party providers and consumers with exhaustive switches or Record<ReasoningLevel, ...> mappings must handle max before upgrading. Ordinary calls using existing reasoning levels remain accepted.
  • Amazon Bedrock: Existing Nova 2 calls using portable reasoning: 'xhigh' now send maxReasoningEffort: 'high' instead of the unsupported 'max', and return a compatibility warning. Anthropic and OpenAI Bedrock effort mappings retain their existing xhigh behavior. Partial Bedrock reasoning configurations continue to preserve explicit values and derive missing fields; explicit effort/budget overrides and disabled thinking no longer emit warnings for portable mappings that are not sent.
  • Fireworks: Existing portable minimal and xhigh calls keep their request mappings to low and high, respectively, and now return compatibility warnings in generation and streaming results. Portable max maps to high with the same warning behavior.

  Release classification: This remains a patch changeset under the repository's explicit release policy, which uses patch releases for both fixes and features. The TypeScript source-compatibility caveat for exhaustive consumers is disclosed above. Maintainers can override this classification with a major label if they decide to align the provider-spec addition with a future AI SDK major release.
