| # Before turning them on, apply these Supabase migrations in order: | |

| # supabase/migrations/20261031193200_math_answer_grading.sql (automatic checks) | |
| # supabase/migrations/20261103120000_math_answer_scan_decline.sql (declining a phone photo request) | |

| # A private Hugging Face storage bucket for new answer images (photos and the board's hand-ins), instead of | |
| # Supabase Storage: reading them back to grade and show them is then not Supabase egress. Images saved before | |

| # Apply supabase/migrations/20261103180000_math_push_subs.sql first. Make a key with: python -m app.push | |
