## Resolved (4)

- Ambiguous naming for client status/info retrieval methods. 'query_info' and 'info' are semantically similar and could be confused, especially if one returns query-specific metadata and the other general connection status.
- Inconsistent parameter naming for the same operation across synchronous and asynchronous client implementations. The synchronous client uses 'options' while the async (EventMachine) client uses 'opts'.
- Off-boarding risk: anonymized user #1
- Workflow token permissions not restricted

## New (7)

- Duplicated block (15 lines × 2) (support/ruby_enc_to_mysql.rb)
- Inconsistent parameter naming convention between synchronous and asynchronous (EventMachine) clients. The sync client uses 'options' while the async client uses 'opts'.
- Off-boarding risk: anonymized user #1
- Orphaned file (lib/mysql2/error.rb)
- Redundant factory method. Ruby idioms typically use 'new' or 'initialize' for construction. 'new_with_args' is non-standard and duplicates the functionality of 'initialize' (which is called by 'new').
- Workflow token permissions not restricted (.github/workflows/build.yml)
- Workflow token permissions not restricted (.github/workflows/rubocop.yml)
