Added Frontend - #82
Conversation
📝 WalkthroughWalkthroughAdds the RotiWorld requirements document and replaces project placeholders. Adds a responsive frontend for chapati image selection, preview, API-based contour matching, mock fallback results, and country result presentation. ChangesRotiWorld application
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The new upload and matching experience is not ready to merge because it can show results for the wrong image, fabricate matches when detection fails, vary fallback results, or remain stuck on slow requests.

In `@frontend/script.js`:
- Line 231: Update the analyzeChapati flow to associate each analysis request
with the current image-selection state, then ignore or cancel the response when
the selected image changes or is cleared before await completion. Ensure stale
responses cannot update the preview or analysis result, while the latest request
continues to apply normally.
- Around line 238-244: Update the contour-handling flow around matchContour to
reject an empty contour with the existing retake error instead of calling
renderResult, then render the detected outline and require explicit user
confirmation before sending the contour to matching.
- Line 167: Update the calculateProfile call to seed mock ranking results with
stable image data instead of the per-selection state.imageUrl blob URL,
preferably reusing state.imageFile.name or an existing content hash while
preserving the “chapati” fallback when no file data is available.
- Around line 189-192: Update analyzeChapati and matchContour to use a shared
timeout helper that supplies an AbortSignal to each fetch and enforces a request
deadline. Handle timeout or request failures by displaying a retryable error,
while preserving runRealAnalysis’s finally cleanup so isAnalyzing is reset and
avoiding silent fallback behavior.
In `@RotiWorld_PRD.md`:
- Line 99: Update the FR2.1 image-upload requirements to define decoded-image
safeguards in addition to the encoded max_upload_mb limit: enforce maximum width
and height, a maximum pixel count, decoder resource limits, and request
concurrency limits for unauthenticated uploads, with configurable values and
documented defaults where appropriate.

Use a stable seed for mock results.
state.imageUrl is a new blob URL on each selection. The same image can therefore produce different fallback rankings. Seed calculateProfile with stable file data, such as state.imageFile.name, or a content hash.

MDN Fetch API fetch promise resolves when response is available AbortSignal timeout
💡 Result:
The fetch promise resolves as soon as the browser has received the response status and headers from the server, potentially before the response body has been fully received [1][2][3]. This design allows developers to inspect status codes and headers (such as Content-Type) before deciding whether or how to consume the body [1][3]. Reading the body is a separate asynchronous operation (e.g., using response.json, response.text, or response.blob) that occurs after the initial fetch promise has resolved [4][3]. When using AbortSignal.timeout with fetch, the signal triggers an abortion if the operation does not complete within the specified time [5][6]. If the timeout expires while the request is pending, the fetch promise will reject with a TimeoutError DOMException [5][7][6]. This allows code to distinguish between a timeout (where the browser-enforced time limit was reached) and other types of request failures [7][6]. Note that fetch itself only rejects on network errors or other request-related failures; it does not reject for HTTP error status codes (like 404 or 500) [1][8][9].

Bound both API requests with a deadline.
analyzeChapati and matchContour call fetch without an AbortSignal. If either request remains pending, runRealAnalysis cannot reach finally to reset isAnalyzing. Add a shared timeout helper and show a retryable error instead of silently falling back.

Discard stale analysis responses.
The image-selection and remove controls remain active while this request is pending. If the user selects or clears an image before this await resolves, the old response can overwrite the new preview and result. Associate each run with an identifier and cancel or ignore it after the selected image changes.

Require a valid outline and user confirmation.
Lines 238-241 render a mock country when analysis returns no contour. Line 244 then sends every non-empty contour directly to /api/match. This bypasses the required retake and confirmation flow. Show a retake error for an empty contour. Render the detected outline and wait for explicit confirmation before matching.
