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.

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, prototype state and repository status, review and sharing workflows, local comment capture and storage, reviewer profiles, Controls diagnostics and validation, and chat diagnosis requests now have authored `index.mts` files. Servers, browser launch, preview connection 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. +Review, local comment, sharing and Controls diagnostic types also live with their owning modules. Comment snapshots, reply receipts, local drafts and diagnosis request timestamps are checked when read from private storage. Malformed records fail explicitly rather than appearing empty or allowing an uncertain write to replay. The bundled Controls validator remains generated JavaScript from Hub's canonical validator; `validate-controls/controls-validator.d.ts` declares only the validation function and error fields consumed by the extension, outside the rebuilt assets directory. + 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.

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.

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, prototype state and repository status, review and sharing workflows, local comment capture and storage, reviewer profiles, Controls diagnostics and validation, and chat diagnosis requests now have authored `index.mts` files. Servers, browser launch, preview connection 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. +Review, local comment, sharing and Controls diagnostic types also live with their owning modules. Comment snapshots, reply receipts, local drafts and diagnosis request timestamps are checked when read from private storage. Malformed records fail explicitly rather than appearing empty or allowing an uncertain write to replay. The bundled Controls validator remains generated JavaScript from Hub's canonical validator; `validate-controls/controls-validator.d.ts` declares only the validation function and error fields consumed by the extension, outside the rebuilt assets directory. + 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.

Subject: [PATCH 16/19] refactor(canvas): type local runtime and server lifecycle Migrate local servers, preview proxy, connection storage and development-server lifecycle to strict TypeScript while

A fresh panel or provider restart can restore that connection. Explicit URL input overrides the saved connection. Opening a saved or explicit URL checks that its server responds before displaying the preview; it never starts the server. +If a saved connection cannot be restored, the error identifies the saved connection and explains recovery. Open the canvas with a valid `prototypeUrl`, then invoke `connect_prototype` with that URL to save a replacement. An explicit-URL open alone does not overwrite the saved connection. + The connected preview checks its server through a protected endpoint every five seconds, with a two-second connection timeout. A failed connection returns the same panel to server selection, with restart instructions below the headline when no servers are found. Users can restart and reconnect the server or choose another one; the saved connection remains available for future opens. HTTP error responses and redirects count as reachable so the iframe can show dev-server diagnostics or follow the page's normal navigation. The setup and renderer servers stay alive until the panel closes, and reconnecting to the same target reuses the renderer server without revoking Hub authorization. The initial renderer load, window focus, and `refresh_status` canvas action read git and GitHub again. A lightweight Hub status refresh checks the current checkout every 15 seconds; the branch shown and Hub prototype change when the checkout changes. State reads, refreshes, and publish requests select a separate state file when the checkout switches branches. The renderer reads cached state every 15 seconds when idle, but refreshes git and GitHub workflow status while a publish is pending. Periodic polls wait for the preceding request to finish rather than discarding slow responses. Hub status refreshes independently, so a newly imported Build updates the open canvas even without window focus. A prior successful Build remains in the Hub panel but does not complete a new publish: the matching Build must advance beyond the Build number captured at request time, without comparing timestamps across machines.
