Anchor validation for the Node extension is built from `utils/review-anchor/validate-anchor.ts`, which is covered by Hub's shared type check. The build minifies the generated validator; its TypeScript source remains unminified. Edit migrated `.mts` sources, not their generated `.mjs` files. The extension's `tsconfig.json` checks them in strict mode with unchecked-index protection and uses Hub's locked Node types. Storage readers expose parsed JSON as `unknown`; consuming TypeScript workflows must check its fields before using them. Hub's `typecheck` and `lint` commands include migrated modules. Run `extension:modules:build` to compile them and format every emitted runtime module without rebuilding the browser assets. Commit generated `.mjs` files alongside their TypeScript source so the plugin still runs without installed packages or a TypeScript loader. The host entry point remains `extension.mjs`. +The Hub client exports its connection, request, status and recall contracts from its owning module. Requests return records with unknown field values; a response being valid JSON does not establish a prototype, review or sharing contract. Consuming workflows must check the fields they use. Stored credentials, saved origins, discovery responses and learnings are checked at their respective read boundaries. No Hub bearer credential reaches the renderer. + Hub builds renderer files, Brand fonts and browser runtime into the plugin's `assets/`; commit them so installed users need no Node packages. Build configuration lives in `hub/vite.prototype-canvas.config.mjs` and `hub/script/`. Generated assets are excluded from formatting checks; do not edit them manually. There is no Vite/npm distribution or release preparation. For example, a preview reload must cancel an unconfirmed click without losing a command already dequeued by the agent. Test each hook's public behavior beside its implementation, using fake timers for polling and timeouts. Keep cross-feature checks under `application/prototype-canvas/tests/`, including iframe preservation, focus restoration and explicit publication or sharing actions. Keep `index.test.tsx` beside the application component and test-only orchestration helpers under its `tests/`. Shared publication fixtures stay with the publication utility so lower-layer tests do not import application code. Create fresh fixtures inside each case without suite-level reset hooks. Shared jsdom setup supplies stateless browser shims and restores real timers; Vitest configuration resets mocks and stubbed globals before each case.
