fix: resolve local dev mode crashes (Firebase mock + wrong parsing endpoint)

[sharwariakre]

Summary

Two bugs that affect every contributor running locally without Firebase credentials.

Bug 1: Firebase _stopProactiveRefresh crash on page reload

File: configs/Firebase-config.ts, lib/utils.ts

When running in mock Firebase mode (no NEXT_PUBLIC_FIREBASE_API_KEY set), the app crashes on page reload with:

TypeError: auth.currentUser._stopProactiveRefresh is not a function

Root cause: getAuth() uses indexedDBLocalPersistence by default. On reload, Firebase restores the previously persisted mock user from IndexedDB and calls _stopProactiveRefresh() on the plain JSON object, which does not have that method.

Fix: Switch to initializeAuth(firebase_app, { persistence: inMemoryPersistence }) so Firebase never writes or restores auth state from IndexedDB. Also added _stopProactiveRefresh and _startProactiveRefresh stubs to generateMockUser() as a secondary guard.

Bug 2: Parsing status always returns 404

File: services/BranchAndRepositoryService.ts

After submitting a repo for parsing, the status never updates — the request silently fails with a 404.

Root cause: checkParsingStatus() was calling /api/v1/check-status which does not exist. The correct backend route is /api/v1/parsing-status.

Fix: Updated the endpoint to match the actual backend route.

---

Note

QuestionSection.tsx has a pre-existing TypeScript error unrelated to this fix — the build was already failing on main before these changes.

Test plan

• Run locally without any Firebase env vars set
• Reload the page — no _stopProactiveRefresh crash in console
• Submit a repo for parsing and confirm status updates correctly

Walkthrough

This PR updates Firebase mock authentication to use in-memory persistence and extends the mock user object with required SDK methods, while also remapping the parsing status service endpoint from /api/v1/check-status to /api/v1/parsing-status.

Changes

Firebase Mock Auth and Service Endpoint

Layer / File(s)	Summary
Firebase mock auth with in-memory persistence configs/Firebase-config.ts, lib/utils.ts	Firebase auth imports gain initializeAuth and inMemoryPersistence. Mock auth initializes with in-memory persistence and descriptive comments. Mock user object gains _stopProactiveRefresh and _startProactiveRefresh methods to prevent missing property errors in SDK interactions.
Parsing status endpoint update services/BranchAndRepositoryService.ts	checkParsingStatus POST request endpoint changes from /api/v1/check-status to /api/v1/parsing-status; payload and error handling unchanged.

🐰 Firebase mocks now rest in peace,
With in-memory stores—no storage release,
Mock methods stand guard, refresh held tight,
And endpoints align for parsing's flight! 🚀
