/**
 * VCR request extraction helpers for adapters
 *
 * Provides type definitions and interfaces for implementing VCR-style
 * request extraction and cassette recording in adapters.
 *
 * ## What is VCR?
 * VCR stands for "Video Cassette Recorder" - a testing pattern that records
 * interactions with external services and replays them in tests. This enables:
 * - Faster test runs (no network calls)
 * - Deterministic tests (no flaky external services)
 * - Offline testing (works without service access)
 * - Cost savings (fewer API calls)
 *
 * ## Key Types
 * - **RequestExtractor**: Interface for extracting request data from test specs
 * - **OperationData**: Normalized request data format for cassettes
 * - **Cassette**: Container for recorded interactions
 * - **Interaction**: Single request/response pair
 *
 * ## Usage
 * Adapters implement RequestExtractor to define how their requests are extracted:
 *
 * ```typescript
 * import { RequestExtractor, OperationData } from "@wavespec/kit/vcr";
 * import type { TestSpec } from "@wavespec/types";
 *
 * export class MyAdapterRequestExtractor implements RequestExtractor {
 *   extract(spec: TestSpec): OperationData {
 *     return {
 *       operation: spec.operation,
 *       data: { ... }
 *     };
 *   }
 * }
 * ```
 *
 * @module @wavespec/kit/vcr
 * @see RequestExtractor for implementation guide
 * @see OperationData for data structure
