Формулы в JS-литералах имели \\\\dfrac / \\\\\\\\dfrac (4/8 слэшей) вместо
\\dfrac (2). После JS-анескейпа KaTeX получал \\dfrac, трактовал \\ как
перенос строки и печатал dfrac/cdot/sqrt/pi как текст (карточка пирамиды и
конуса в geometry_11_ch2, и др.).
Схлопнуты прогоны слэшей кратные 4 перед LaTeX-командой -> 2. Прогоны из
3 слэшей (\\ перенос строки + \cmd в \begin{cases}) и перед x/цифрой не
тронуты. 150 правок в 7 файлах (algebra_11_ch1/ch2/ch3, geometry_11_ch1..ch4).
БД чиста: questions (1398) text/explanation/correct_text + options (5187) -

dry-run по умолчанию, --apply, с KaTeX-валидацией).

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
