-| `website` `typescript` | **`6.0.3`**, behind the root's TypeScript 7, because `typedoc@0.28` peers on `<= 6.0.x`. TypeDoc compiles the built `packages/agent-bundle/dist` declarations with it, while Twoslash compiles documentation samples against package source. Re-pin chores check whether a newer `typedoc` lifts the ceiling. |
+| `website` TypeScript | Native **`7.0.2`** runs `tsc`; the `typescript-6` alias stays on **`6.0.3`** for TypeDoc, Twoslash, and `rspress.config.ts` compiler-API calls. `.pnpmfile.cjs` turns those plugins' TypeScript peers into dependencies, and the scoped overrides in `pnpm-workspace.yaml` isolate them from TypeScript 7. Re-pin chores update the alias and overrides together. |
 
 Application code imports the npm package. Never import from `repos/**`.
