       # Class System Specification

     

       2
       +

       +
       ## Overview

     

       4
       +
       

     

       5
       +
       Restructure Thistle from individual transcript management to class-based transcript organization. Users will manage transcripts grouped by classes, with scheduled meeting times and selective transcription.

     

       6
       +
       

     

       7
       +
       ## User Flow

     

       8
       +
       

     

       9
       +
       ### 1. Classes Page (Home)

     

       10
       +
       - Replaces the transcript page as the main view after signup

     

       11
       +
       - Displays grid of class cards organized by semester/year

     

       12
       +
       - Each section (semester/year combo) separated by horizontal rules

     

       13
       +
       - Each card shows:

     

       14
       +
         - Course code (e.g., "CS 101")

     

       15
       +
         - Course name (e.g., "Introduction to Computer Science")

     

       16
       +
         - Professor name

     

       17
       +
         - Semester and year (e.g., "Fall 2024")

     

       18
       +
         - Archive indicator (if archived)

     

       19
       +
       - Final card in grid is "Register for Class" with centered plus icon

     

       20
       +
       - Empty state: Only shows register button if user has no classes

     

       21
       +
       

     

       22
       +
       ### 2. Individual Class Page (`/classes/:id`)

     

       23
       +
       - Lists all recordings and transcripts for the class

     

       24
       +
       - Shows meeting schedule (flexible text, e.g., "Monday Lecture", "Wednesday Lab")

     

       25
       +
       - Displays recordings with statuses:

     

       26
       +
         - **Pending**: Uploaded but not selected for transcription

     

       27
       +
         - **Selected**: Marked for transcription by admin

     

       28
       +
         - **Transcribed**: Processing complete, ready to view

     

       29
       +
         - **Failed**: Transcription failed

     

       30
       +
       - Upload button to add new recordings

     

       31
       +
       - Each recording tagged with meeting time

     

       32
       +
       

     

       33
       +
       ### 3. Recording Upload

     

       34
       +
       - Any enrolled student can upload recordings

     

       35
       +
       - Must select which meeting time the recording is for

     

       36
       +
       - Recording enters "pending" state

     

       37
       +
       - Does not auto-transcribe

     

       38
       +
       

     

       39
       +
       ### 4. Admin Workflow

     

       40
       +
       - Admin views pending recordings

     

       41
       +
       - Selects specific recording to transcribe for each meeting

     

       42
       +
       - Only selected recordings get processed

     

       43
       +
       - Can manage classes (create, archive, enrollments)

     

       44
       +
       

     

       45
       +
       ## Database Schema

       100
       +
       - `transcripts(class_id)` - lookup class transcripts

     

       101
       +
       - `transcripts(status)` - filter by status

     

       102
       +
       - `meeting_times(class_id)` - lookup class schedule

     

       103

       104
       +

       +
       - Non-enrolled users get 403 when accessing `/classes/:id`

     

       110

       ## Migration Strategy

     

       182
       +
       

     

       183
       +
       **Breaking change**: Reset database schema to consolidate all migrations.

     

       184
       +
       

     

       185
       +
       1. Export any critical production data (if needed)

     

       186
       +
       2. Drop all tables

     

       187
       +
       3. Consolidate migrations in `src/db/schema.ts`:

     

       188
       +
          - Include all previous migrations

     

       189
       +
          - Add new class system tables

     

       190
       +
          - Add new columns to transcripts

     

       191
       +
       4. Restart with version 1

     

       192
       +
       5. Existing transcripts will be lost (acceptable for this phase)

     

       193
       +
       

     

       194
       +
       ## Admin UI Updates

     

       195
       +
       

     

       196
       +

       +
         - Course name

     

       200

       +
       - Delete class button

       ## Open Questions

     

       238
       +
