re-saved via PUT; locate the recalculation using

z.string().min(1), then keep using StudentSchema.safeParse and Student.create({

In `@models/Attendance.ts`:
- Line 27: The schema change adds AttendanceSchema.index({ teacherId: 1,

update the seed logic that currently creates the { studentId:1, date:1} index to
create the new { teacherId:1, studentId:1, date:1 } unique index instead, and
add a one-off migration (e.g., "add-teacher-to-attendance-index") that drops the
existing unique index on { studentId:1, date:1 } if present and then creates the
new unique index on { teacherId:1, studentId:1, date:1 } in an idempotent way
(handle index-not-found errors gracefully).
In `@proxy.ts`:
- Around line 18-23: The matcher in export const config currently uses

🌐 Web query:
Does Mongoose run schema validators by default for findOneAndUpdate, or is runValidators: true required?
💡 Result:
No, Mongoose does not run schema validators by default for findOneAndUpdate. The runValidators option must be set to true to enable update validators.
Citations:
- 1: https://mongoosejs.com/docs/validation.html
- 2: https://mongoosejs.com/docs/8.x/docs/validation.html
- 3: https://mongoosejs.com/docs/7.x/docs/validation.html
Add runValidators: true to the findOneAndUpdate call.
Mongoose does not run schema validators by default for findOneAndUpdate. Without the runValidators option, a teacher can submit allowed fields with invalid values (such as an invalid status enum or negative maxMarks) and persist them to the database. The ownership filter is correct, but data validation is still needed.

Keep PUT grading consistent with POST creation.
app/api/grades/route.ts:22-30 assigns B+, B, C, and D, but this PUT path collapses those into B/F. A grade created at 75% becomes B+, then the same marks saved through PUT become B.

Add ObjectId validation to DELETE handler for consistent error handling.
The PUT handler validates the grade id with mongoose.Types.ObjectId.isValid(id) and returns 404 for malformed IDs. The DELETE handler skips this check and passes the id directly to findOneAndDelete, causing Mongoose to throw a CastError that gets caught and returns 500 instead of 404. This creates an inconsistency in error responses between the two endpoints.

Add .trim() to required string fields in StudentSchema.
The validation accepts whitespace-only strings for name, rollNo, and class because z.string().min(1) validates string length without trimming. This allows creating student records with blank-looking values.

Update seed.mjs and add index migration.
The schema fix on line 27 is correct, but the seed script still creates the old { studentId: 1, date: 1 } index (scripts/seed.mjs:105). Additionally, existing deployed databases will retain the old unique index and need an explicit migration to drop it and create the new { teacherId: 1, studentId: 1, date: 1 } index. Without both changes, fresh seeds and existing production data will continue to fail with cross-teacher duplicate key errors.

In `@models/Attendance.ts` at line 27, The schema change adds
AttendanceSchema.index({ teacherId: 1, studentId: 1, date: 1 }, { unique: true
}) but the seed script still creates the old { studentId: 1, date: 1 } unique
index and deployed DBs keep the old index; update the seed logic that currently
creates the { studentId:1, date:1} index to create the new { teacherId:1,
studentId:1, date:1 } unique index instead, and add a one-off migration (e.g.,
"add-teacher-to-attendance-index") that drops the existing unique index on {
studentId:1, date:1 } if present and then creates the new unique index on {
teacherId:1, studentId:1, date:1 } in an idempotent way (handle index-not-found
errors gracefully).

Restore static-asset exclusions in the proxy matcher.
Line 21 excludes only _next, static, and favicon.ico. This causes common static assets like .png, .css, .svg, .webmanifest, and .txt files to be matched by the middleware, triggering auth.protect() on them and blocking unauthenticated access before sign-in.
The repository contains actual static assets (public/file.svg, public/globe.svg, app/globals.css, etc.) that would be affected. Replace the basic exclusion pattern with a comprehensive file-extension-based exclusion:
Proposed matcher fix
export const config = {
matcher: [
// Optimized matcher for Next 16 proxy layer
- '/((?!_next|static|favicon.ico).*)',
+ '/((?!_next|[^?]*\\.(?:html?|css|js(?!on)|jpe?g|webp|png|gif|svg|ttf|woff2?|ico|csv|docx?|xlsx?|zip|webmanifest)).*)',
'/(api|trpc)(.*)',

In `@proxy.ts` around lines 18 - 23, The matcher in export const config currently
uses '/((?!_next|static|favicon.ico).*)', which still routes requests for common
static files through middleware and triggers auth.protect(); update the matcher
string in the config.matcher array to exclude static asset file extensions
(e.g., .png, .jpg, .jpeg, .gif, .svg, .ico, .css, .js, .webmanifest, .txt, .map,
.woff, .woff2, .eot, .ttf, .otf, .json) using a negative lookahead regex so
those files bypass middleware, while keeping the '/(api|trpc)(.*)' entry intact.
