# Vibe Studio — local identity and creation-form check 24 September 2026. The current source can run locally; production-only availability in the earlier course describes its original captured deployment, not a technical restriction of this checkout. ## Actual local browser result An isolated Vite frontend on port 5179 used the real review AppEngine on port 3312. Project `.env` loading was disabled; no environment secrets were read or printed. Its session-manager URL was an unused loopback port 3759. That backend was deliberately not started. The independent browser blocked non-loopback requests. 1. Entered the existing review owner’s email and selected **Continue with Password**. 2. Entered the actual local organisation in **Site Name**, entered its private password, and selected **Sign In**. 3. Reached **Build your ideas with Vibe**, with the review identity in the sidebar and no existing development environments. This was normal authentication, not injected browser storage or a fabricated session. 4. Entered the course’s complete expanded 1,995-character brief in **Describe your idea...** and selected **Build**. 5. **Create New Project** opened with **App**, **Design**, the description and **Dev Environment Name**. Compared the full carried description with the original: exact match. Entered a proposed local project name for the screenshot. **Create Dev Environment was not submitted.** Cancelled the form, reloaded the entire page and confirmed the authenticated Start returned. [Authenticated Start](assets/vibe-local/start-authenticated.png) · [Unsubmitted creation form](assets/vibe-local/create-form-unsubmitted.png) · [Session after reload](assets/vibe-local/session-after-reload.png) This proves local sign-in and the brief-to-form handoff only. It does not prove project provisioning, generation, files, preview behaviour, customer data integration or production access. ## Services required for the remaining workflow - **Frontend:** `agent-zero/vibe-studio`; Vite, React and installed dependencies are available. `VITE_API_HOST` selects AppEngine. `VITE_SESSION_MANAGER_URL` selects the separate file/session service. - **AppEngine:** an authenticated organisation with development-environment entitlement. `createDevEnv` first calls its `dev-env/create` endpoint. This is a real record write, not just opening a dialog. - **Session manager:** `agent-zero/session-manager`, Express/Socket.IO; configured loopback host/port, CORS matching the frontend, writable isolated project directories, persistence/log directories and `APPMINT_HOST` pointing at the local API. Its default AppMint host on some server routes is production, so a local run must override that explicitly. Frontend creation next calls this service to create the corresponding project directory. A missing session manager can therefore leave the AppEngine record created while the second stage fails. - **Generation:** the bridge launches the configured Claude CLI with the submitted prompt, project identity/instructions and project MCP tools. It inherits the process environment and provider authentication. The carried prompt can be sent automatically when the new editor opens. A real authorized model session is required to verify the expanded brief; a fabricated output or manually written fixture would not satisfy this course’s generation check. - **Connected app:** the two-customer ownership and backend contract tests are separate from the sample-data prototype, even after generation succeeds. No session-manager process, CLI model call, deployment or provider action was started in this pass. No application source was changed. The production project in earlier screenshots was not accessed or modified. ## Continuation: provisioning and failed-run recovery passed The isolated local session manager now runs on loopback3759, with its own project/persistence directories, local AppEngine3312 and model executable deliberately unavailable. Normal browser sign-in followed the course's complete1,995-character brief, Build, project name `tutorial-client-dashboard-20260924` and Create Dev Environment. AppEngine returned201; session-manager returned200. The editor opened the existing new project and reopened it after reload. Do not create it again. This advanced beyond the initial cancelled-form check. The supplied brief caused the editor to attempt its initial generation automatically. No model process started because the configured executable was unavailable. That controlled failure exposed a real defect: the assistant bubble was blank, and the backend saved it as complete before delivering the error. Fixed `session-manager/src/services/bridge.service.ts` to persist failed/cancelled turns correctly and emit the task-specific error before stream end. Fixed `vibe-studio/src/components/ai-chat/chat-store.ts` and `services/socket-client.ts` to match a failed task even after a final state event cleared the active task. Actual Chromium retest displays the ENOENT error; a full reload preserves both its text and error status. No generated output or provider success is claimed. [Before: blank error](assets/vibe-local/creation-empty-error-before.png) · [After](assets/vibe-local/runner-error-fixed.png) · [After reload](assets/vibe-local/runner-error-after-reload.png) · [Sanitized proof](assets/vibe-local/provisioning-proof.json). Session-manager semantic typecheck passes with unused-symbol/noImplicitReturns checks disabled. Its default strict command still reports existing unused symbols and incomplete-return paths, including outside edited files; a clean default build is not claimed. Live browser/service verification passed for this repair. Generation, generated files/preview, and connected customer ownership acceptance remain open. ### Connection badge repair The editor header always read Disconnected because it used an application-store field with no connection updates. The Files area correctly read Connected. `vibe-studio/src/components/layout/Header.tsx` now uses the actual file-store connection state. Browser verification: both areas Connected; stopped only the isolated session manager and saw Disconnected; restarted it and both areas returned to Connected. Frontend production build passed (existing large-chunk warning). This badge reports connection, not model availability. ### Independent file editor acceptance In the real editor, selected Create a file, entered `tutorial-editor-check.txt`, selected Create File, typed `Local editor persistence check. Fictional tutorial note.` and pressed Cmd+S. The Save indicator cleared. The actual file on disk contains that exact text. Full browser reload, selecting the file again and reading its editor text passed. [Reopened file](assets/vibe-local/manual-file-reopened.png). This is a manually authored editor check, not generated application content or preview acceptance. The browser initially blocked the editor's static Monaco CDN dependency as part of the test's own localhost-only filter. Allowing the precise public Monaco asset path restored the editor. That test restriction was not recorded as an application defect. Backend/API traffic stayed local and model execution stayed disabled. The historical empty completed message also rendered a permanent Thinking indicator. `ChatMessage.tsx` now shows that indicator only during thinking/streaming, and describes an empty completed record as “No response text was saved for this message.” Browser reload verified one empty-record explanation, no lingering Thinking indicator and the separate repaired error still visible. Historical records were not rewritten to invent a missing result. ## Current-source generation continuation — 24 September The local CLI status was rechecked with normal host access and confirmed an existing authenticated first-party session. Restricted-shell status had incorrectly suggested that no host login existed. No credentials were copied or displayed. Restored the existing project and normal UI sign-in; did not recreate the environment. The initial generation retry exposed stale compiled output: `dist/config/config.js` still selected `claude-sonnet-4-20250514`, which the provider rejected. Current `src/config/config.ts` already leaves the model unset so the CLI selects its current default. The isolated service now executes current TypeScript source through `tsx`. Source review also found the appended generator instructions always required `build_project`, which publishes a preview, even when the user requested a local static prototype with no deployment. Updated `session-manager/src/services/bridge.service.ts` to respect explicit local-only, no-network and no-deployment scope, use local files/editor preview, and require build/status verification only when preview publication is in scope. Semantic TypeScript validation passed with the same previously documented unused-symbol/noImplicitReturns flags disabled. The exact 1,995-character course brief was resubmitted through AI Assistant, with an explicit instruction to preserve the manual check file and keep generation in the existing project. Actual model generation began. Acceptance results will follow after the generated controls are exercised; an in-progress generation screenshot is not completion evidence. ### Fresh generation and independent prototype acceptance passed The actual authenticated CLI completed the expanded brief in the existing `tutorial-client-dashboard-20260924` project. It produced `index.html`, `styles.css` and `app.js`, preserved `tutorial-editor-check.txt`, and set project metadata `framework` to `static`. No additional feature-refinement prompt was needed. The previous retired-model failure came from stale compiled output, not the current source's model selection. No deployment/build/publish tool was called. Actual Chromium checks, through **Preview → Browse**: - Maya: **Bennett Townhouse — Living Room & Study**, **In progress**, **Material selection**, **55%**, four sample documents and the required shelving decision. - Jordan: **Lee Garden Apartment — Full Redesign**, **Awaiting your input**, **Concept review**, **30%**, three sample documents and the required concept decision. Switching fixtures showed the simulated loading state first. - **Loaded**, **Loading**, **Empty**, **Error** all worked. **Try again** showed loading and returned to the same selected client. - The specified Living room / Soon / oak-swatch request produced the exact demo acknowledgement and echoed input. Captured iframe network requests during submit/reset: **zero**. **Send another** cleared the form. - The mobile form accepted the same request. A full browser reload reopened the project with Maya and an empty form, with no acknowledgement. Generated files persisted. - Mobile, tablet and desktop device controls all rendered without horizontal document overflow. Their labels are 375/768/1280px; actual tested iframe widths were 393/820/1003px because the device emulation and available editor space determine the viewport. No fixed-width screenshot is claimed to represent a physical-device test. - **Code → app.js** showed the actual fixtures in the editor. **Terminal** expanded its output panel; no interactive command was entered. **Launch** showed project, default live URL, owner, organization, custom-domain controls and **Deploy now**. We only inspected it: no deployment, domain attachment, synchronization or invitation. [Acceptance JSON](assets/vibe-local/generation-acceptance.json) · [Maya](assets/vibe-local/generated-maya-preview.png) · [Jordan](assets/vibe-local/generated-jordan-preview.png) · [Loading](assets/vibe-local/generated-loading-preview.png) · [Empty](assets/vibe-local/generated-empty-preview.png) · [Error](assets/vibe-local/generated-error-preview.png) · [Request echo](assets/vibe-local/generated-request-echo.png) · [Mobile request](assets/vibe-local/generated-mobile-request.png) · [Reload reset](assets/vibe-local/generated-reopened-preview.png) · [Code](assets/vibe-local/generated-code.png) · [Terminal](assets/vibe-local/generated-terminal.png) · [Launch inspection](assets/vibe-local/generated-launch-inspection.png). The new output uses client labels rather than “Hi Maya”/“Hi Jordan”. Wait for the exact project heading when checking fixture changes. This remains a fictional prototype, not connected customer data or a published app. Vibe automatically inserts its local element-selector script into HTML; that editor integration is separate from the prototype form, which sends no request. ### Generated Files tree refresh repaired The first successful generation wrote its files to disk, but **Files** still showed only the old manual check file until page reload. The CLI writes directly to disk and completion did not send an updated tree. `bridge.service.ts` now invokes the existing project tree handler before `ai:stream_end`, including failed/cancelled turns that may leave partial files. Live verification used a read-only model follow-up in the same project. Captured actual WebSocket events showed **file:tree**, containing all four filenames, immediately before **ai:stream_end**. The Files pane displayed them without reload. Hashes of all four files were unchanged across this follow-up. [Event proof](assets/vibe-local/file-tree-completion-events.json) · [Actual Files pane](assets/vibe-local/generated-files-refreshed.png). ### Repeated final assistant text repaired The read-only follow-up exposed duplicated final prose: the CLI emits the assistant block and then repeats it in its final result event. The bridge appended both. It now preserves result-only responses and distinct result text while skipping a final result already at the end of the accumulated turn. Four isolated event regressions passed: duplicate final, result-only, distinct result and empty result; usage events remain intact. [Regression source](assets/vibe-local/stream-result-regression.ts) · [Results](assets/vibe-local/stream-result-regression.txt). This repair is installed in the running local source service; historical conversation records were not rewritten. Current isolated frontend: 5179. Current-source session manager: 3759. Generated project and session data have been copied into the existing private crash-recovery state. No production service or global CLI configuration was changed.
