feat(study-goals): add study goals & weekly analytics system - #2271
Conversation
The controller required completedTopics to be an Array, but the frontend,
the Zod validator (z.record), the Mongoose schema ({ type: Object }), the
import util, and resetProgress all use an object/map — so every save hit
!Array.isArray({...}) and returned 400, and progress was silently lost
(kept only in localStorage). Validate it as a plain object instead.
Fixes Canopus-Labs#1727
…ntract)
Per review: the object check accepted any non-null object, so { "0-0-0": "true" }
(string value) passed. Also require every value to be a boolean, matching the
Zod z.record(z.string(), z.boolean()) contract and the map/{key:bool} shape.

# Pull Request: Add Google Calendar Backend Routes
## Summary
This PR adds the missing backend routes required by the Interview Prep frontend for Google Calendar integration.
The frontend already defines the following Google Calendar API paths in `frontend/src/utils/apiPaths.js`, but the backend did not have a corresponding mounted router. As a result, all Google Calendar actions were returning `404 Not Found`.
## Changes Made
* Added `backend/routes/googleCalendarRoutes.js`.
* Added the following Google Calendar endpoints:
* `GET /api/google-calendar/connect`
* `GET /api/google-calendar/callback`
* `GET /api/google-calendar/status`
* `POST /api/google-calendar/events`
* Mounted the Google Calendar router in `backend/server.js`.
* Added Google Calendar OAuth environment variable placeholders to `backend/.env.example`.
* Kept the implementation lightweight and prepared for future Google OAuth2/token persistence.
* Avoided changes to the existing MongoDB configuration because MongoDB is outside the scope of this issue.
## API Behavior
### GET `/api/google-calendar/connect`
Provides the entry point for initiating the Google Calendar OAuth flow.
### GET `/api/google-calendar/callback`
Provides the callback endpoint required for Google OAuth integration.
### GET `/api/google-calendar/status`
Returns the current calendar connection status.
Example response:
```json
{
"success": true,
"connected": false
}
```
### POST `/api/google-calendar/events`
Accepts calendar event data for synchronization/saving.
Example request:
```json
{
"events": [
{
"title": "Mock Interview",
"start": "2026-08-25T10:00:00",
"end": "2026-08-25T11:00:00"
}
]
}
```
## Environment Variables
Added placeholders for:
```env
GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret
GOOGLE_REDIRECT_URI=http://localhost:5000/api/google-calendar/callback
```
Actual credentials are not included in the repository.
## Testing
Verified the backend Google Calendar endpoints locally:
* `GET /api/google-calendar/connect`
* `GET /api/google-calendar/callback`
* `GET /api/google-calendar/status`
* `POST /api/google-calendar/events`
The routes are now available instead of returning `404 Not Found`.
## Scope
This PR focuses specifically on the missing Google Calendar API routes and backend integration.
Full Google OAuth token persistence and production calendar synchronization can be implemented as a follow-up enhancement.

Archive every elapsed week separately.
If a goal is stale for more than one week, this code writes one record from the old weekStartDate through the Sunday before the current week. It increments totalWeeksTracked once and loses each intervening week. This corrupts weekly history and completion analytics for users who do not open the app every week.
Iterate from the stored week start to the current week start. Archive each week with its own bounds and zero-minute entries for missed weeks.

Archive a stale goal before applying a new weekly target.
If a user changes weeklyTargetMinutes after a week boundary, Object.assign changes the target before maybeArchiveWeek records the prior week. The later archive then stores the new target for the old week.

Reject session dates outside the current completed period.
An authenticated caller can submit any valid ISO datetime. This code adds past or future dates to dailyLog and includes their minutes in currentWeekMinutes. A past session is then archived under the wrong week.
Normalize logDate, then reject dates before goal.weekStartDate or after today before mutating dailyLog.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep the analytics aggregation window consistent. weeklyHistory retains only 12 weeks, but the response labels its sums as all-time values and uses lifetime totalWeeksTracked as a category denominator. Current-week sessions are also absent from these totals. Metrics become incorrect immediately for new sessions and diverge further after retention removes history.

Zod 4.4.3 ZodError issues errors property official documentation
💡 Result:
In Zod v4, including version 4.4.3, the ZodError.errors property has been removed [1]. Users should use the ZodError.issues property instead to access the array of validation issues [1][2][3]. In Zod v3, ZodError.errors served as a getter for ZodError.issues, but this alias was discontinued in v4 [1]. While this removal was not initially highlighted in early v4 migration documentation, it is the established standard for Zod v4 [1]. There is no alias or direct workaround for the.errors property; code relying on it must be updated to reference.issues [1]. Official documentation now emphasizes using utility functions such as z.treeifyError or z.flattenError to process the ZodError object rather than accessing internal properties directly, as these utilities provide more robust ways to traverse and format validation errors [4].
