/**
 * Runtime validation schema and wrapper for OpenAI Responses adapter options.
 *
 * @module @nhtio/adk/batteries/llm/openai_responses/validation
 *
 * @remarks
 * Schema and call-site wrapper for validating `OpenAIResponsesAdapterOptions`. Used at
 * construction time and at the start of every iteration against the merged options shape
 * (stash > executor > constructor). Throws `E_INVALID_OPENAI_RESPONSES_OPTIONS` on failure — same
 * hard-fail policy as every other ADK contract.
 *
 * Notable divergences from the sibling `openai_chat_completions`/`anthropic_messages` schemas:
 * - NO `instructions` key and NO `store` key at all — both are exclusively adapter-owned (see
 *   the battery's design notes). `.unknown(false)` rejects them the same way it rejects
 *   `previous_response_id`/`conversation`/`prompt`/`context_management` — ADK owns history and the
 *   system prompt on every battery; this one simply has no escape hatch for either.
 * - `max_output_tokens` carries `.min(16)` — an undocumented API minimum (`400 Invalid
 *   'max_output_tokens'... Expected a value >= 16`) enforced at config time instead of dispatch
 *   time.
 * - `background` only accepts `false`/undefined — `true` is rejected, since this adapter has no
 *   polling/resumption logic for a queued/in_progress background response (see the option's own
 *   doc comment in types.ts).

 * @remarks
 * Used by `validateOptions` at construction time and again at the start of every iteration after
 * options have been merged (stash > executor > constructor). Rejects unknown top-level keys so
 * typos, removed fields, and every server-side-conversation-state key
 * (`previous_response_id`/`conversation`/`prompt`/`context_management`) fail loud — as does
 * `instructions`/`store`, which are simply not part of this options interface at all (see the
 * module remarks above).
