  // per-provider thinking resolution live — a direct `generateText` / `streamText`
  // silently opts out of all three, and the opt-out is invisible at the call site.
  // The PBL v2 runtime drifted exactly this way (#1003): five direct calls meant
  // zero usage records for the busiest traffic in the product, plus three
  // different meanings for one thinking config.
  //
  // The rule uses the @typescript-eslint variant deliberately: the base
  // `no-restricted-imports` is already configured for lib/choreography and
  // lib/video-export, and flat config REPLACES a rule's options per key rather
  // than merging them, so reusing that key here would silently drop those
  // module-boundary bans. Different key, no interference.
  //
  // Every reachable import form is covered, verified by feeding each one to
  // eslint rather than assumed:
  //   - `import { streamText } from 'ai'`  → this rule
  //   - `import * as ai from 'ai'`         → this rule too; ESLint reports a
  //     namespace import when `importNames` is set, since the namespace would
  //     carry the restricted name
  //   - `require('ai')`                    → the repo-wide
  //     `@typescript-eslint/no-require-imports` (inherited from
  //     eslint-config-next/typescript) already forbids require() anywhere
  //   - `await import('ai')`               → the no-restricted-syntax block below
  // An `eslint-disable` comment defeats any of them, which is the point: the
  // bypass has to be written down where a reviewer sees it.

  // Scope is every linted source extension, matching the module-boundary blocks
  // above — NOT just ts/tsx. An earlier revision guarded only ts/tsx, which left
  // `app/api/route.js` and `scripts/*.mjs` free to import the SDK; review caught
  // it. tests/lint-llm-entry-guard.test.ts pins the whole matrix so the scope
