Added

  • Add mod_log_mysql module: batch idempotent write (INSERT ... ON DUPLICATE KEY UPDATE) of AI access logs to the MySQL table bfe_ai_request_log (89 columns), with a queue + single-writer goroutine and backoff retry.
  • Extract shared protobuf field extraction into reader_modules/mod_fields, reused by mod_kafka (API kept via type aliases) and mod_log_mysql.
  • Add integration test scenario LR03 (basic write, idempotent replay, zero-value-to-null, batch split) against real MySQL via LR_MYSQL_DSN or testcontainers; add module doc, sys_design docs, and conf/mod_log_mysql/mod_log_mysql.conf template.
