Scripts

backup.sh

Creates a safe SQLite snapshot via VACUUM INTO. Keeps last 7 backups (configurable via KEEP=14).

./backup.sh                        # default: ../data/learnspace.db → ../../backups/
./backup.sh /path/to/db /path/to/backups
KEEP=14 ./backup.sh

verify-backup.sh

Restores the latest backup to /tmp, runs PRAGMA integrity_check, compares row counts vs production.

Exit codes:

• 0 — all checks passed
• 2 — no backup files found
• 3 — latest backup older than 48h (backup job may have stopped)
• 4 — integrity_check failed (backup is corrupt)
• 5 — user count diverged >5% from production

npm run lint:routes

import-content.js (coming in Task 8)

Imports question collections from YAML manifests into the database.

npm run import:content -- ../content/phys/ct-2024.yaml
