Problem: Students couldn't mark lessons as complete
Solution: Database migration
-- Migration: 20260130225216_fix_lesson_completion_rls.sql
-- Students can mark lessons complete
CREATE POLICY "Students can mark lessons complete"
ON lesson_completions FOR INSERT
TO authenticated
WITH CHECK (auth.uid() = user_id);
-- Students can view own completions
CREATE POLICY "Students can view own completions"
ON lesson_completions FOR SELECT
TO authenticated
USING (auth.uid() = user_id);
-- Teachers and admins view all
CREATE POLICY "Teachers and admins view all completions"
ON lesson_completions FOR SELECT
TO authenticated
USING (
EXISTS (
SELECT 1 FROM user_roles
WHERE user_id = auth.uid()
AND role IN ('teacher', 'admin')
)
);File: components/student/lesson-comments.tsx

Problem:
// BEFORE (broken)
const { data: course } = await supabase
.from('courses')
.select(`author:profiles!courses_author_id_fkey(...)`)Root Cause: Foreign key referenced wrong table (profiles instead of auth.users)
Solution:
// AFTER (working)
const { data: course } = await supabase
.from('courses')
.select('course_id, title, description, thumbnail_url, author_id')
// Get profile separately
const { data: authorProfile } = await supabase

.select('full_name, avatar_url')
.eq('id', course.author_id)Impact: Course detail page now loads correctly
Date: January 30, 2026
Problem: Students couldn't INSERT into lesson_completions
Solution: Created proper RLS policies (see Phase 8)
Impact: Students can now track progress
