Workflow panels belong in `features/`, reusable fields and dialogs in `components/`, and stateful browser behavior in `hooks/`. Shared contracts, locale copy, protocols and URL helpers live in `utils/`; the Controls engine and definition schema live in `utils/prototype-controls/`. Extension registration and server operations remain in `.github/extensions/replica-prototype/`. +The canvas frontend already uses TypeScript. Extension Node modules are migrating separately, starting with `read-remote-branch/index.mts`. Edit that source, not its generated `index.mjs`. The extension's `tsconfig.json` checks migrated modules in strict mode; declarations describe dependencies that remain JavaScript. Hub's `typecheck` and `lint` commands include these modules. Run `extension:modules:build` to compile them 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`. + 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. @@ -469,4 +471,4 @@ bin/devcontainer exec npm run extension:build bin/devcontainer exec npm run extension:assets:check ``` -`extension:test` runs the root plugin's Node `.mjs` tests, including a real-browser delivery check when `/usr/bin/chromium` is available (as in the devcontainer).

Extension Node modules are migrating separately. Remote-branch checks, command execution, private storage, state-file reads and writes, repository identity and context, Hub clients and connection selection, origin validation and discovery, and the learnings hook now have authored `index.mts` files. Publishing and review workflows, servers, and SDK registration still use authored JavaScript. 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.

Remote-branch checks, command execution, private storage, state-file reads and writes, repository identity and context, Hub clients and connection selection, origin validation and discovery, the learnings hook, publication requests and results, publication preferences and preparation, working-tree checks, and prototype state and repository status now have authored `index.mts` files. Review workflows, servers, and SDK registration still use authored JavaScript. 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`. +Publication workflows use `read-publication-state` to check the saved fields they consume while preserving unrelated fields and legacy requests without a target or mode. Invalid publication fields produce an explicit error instead of being replaced with idle state. Shared target, request, mode, outcome, session, and status types live with their owning modules; Hub and SDK responses remain untrusted until their consumed fields are checked. + 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.

Extension Node modules are migrating separately. Remote-branch checks, command execution, private storage, state-file reads and writes, repository identity and context, Hub clients and connection selection, origin validation and discovery, and the learnings hook now have authored `index.mts` files. Publishing and review workflows, servers, and SDK registration still use authored JavaScript. 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.

Remote-branch checks, command execution, private storage, state-file reads and writes, repository identity and context, Hub clients and connection selection, origin validation and discovery, the learnings hook, publication requests and results, publication preferences and preparation, working-tree checks, and prototype state and repository status now have authored `index.mts` files. Review workflows, servers, and SDK registration still use authored JavaScript. 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`. +Publication workflows use `read-publication-state` to check the saved fields they consume while preserving unrelated fields and legacy requests without a target or mode. Invalid publication fields produce an explicit error instead of being replaced with idle state. Shared target, request, mode, outcome, session, and status types live with their owning modules; Hub and SDK responses remain untrusted until their consumed fields are checked. + 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.
