EDEN 100.9.13 — Validation Report

Release
- Version: 100.9.13
- Based on: 100.9.12

Challenge transaction fix
- Schema migrations for title_entities_json and description_entities_json now run before beginTransaction().
- Both required columns are verified through INFORMATION_SCHEMA before opening the business transaction.
- Detailed failure logs include stage, challenge id, transaction state, exception class, code, and message.
- Rollback is only attempted while the connection reports an active transaction.

Static validation
- schema migrations occur before beginTransaction: PASS
- no schema ALTER migration occurs inside business transaction: PASS
- schema is verified before transaction start: PASS
- failure logs include stage and transaction state: PASS
- failure logs include exception class and error code: PASS
- rollback only runs when PDO reports an active transaction: PASS
- update.json and VERSION both report 100.9.13: PASS
- updater manifest has unique paths: PASS
- all updater manifest paths exist: PASS
- changed runtime module is listed in updater manifest: PASS
- 75 PHP files were linted: PASS

Limitations
- No production database credentials or live Telegram bot were used. The fix is validated by code/static checks and PHP lint, not a live challenge creation.
- A failed creation on the previous release could have partially committed due to MySQL implicit DDL commit; check the challenge list for a recent draft with the same title before retrying.
