content/phys/ct-2024.yaml — 15 questions from ЦЭ,ЦТ 2024 across 6 topics (kinem, mol, emf, electro, magnet, optics) as proof of format. backend/scripts/import-content.js — unified importer: - Validates schema (subject, year, options, exactly-1-correct) - Aliases (kinem, mol, ...) resolve to Russian topic names via get-or-create - Deduplicates by first 80 chars of text (matches legacy seed_*.js behavior) - Runs in a single transaction, idempotent re-runs On fresh DB: 13 added (2 dedup collisions — same 80-char prefix, expected). On prod DB: 0 added (all already exist from legacy seeds). Second run on either: 0 added (dedup works). Legacy seed_phys_ct2024.js kept as backup — see content/README.md for migration guide.

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 passed2— no backup files found3— latest backup older than 48h (backup job may have stopped)4—integrity_checkfailed (backup is corrupt)5— user count diverged >5% from production
./verify-backup.sh

Scans src/routes/*.js for :id-bearing routes without an auth-guard middleware.
Fails if new unprotected routes exceed the current baseline.
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
