Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Command Injection: Command execution via child_process.execSync during git operations was vulnerable to injection through untrusted branch names containing shell metacharacters. Developers must use safe input validation or avoid shell spawning.

Command Injection: Unsanitized tmux session names could inject arbitrary arguments or commands into downstream tmux commands like 'set-option -t'. Safe replacement filters must be preserved.

Remote Code Execution: Parsing file-backed settings from '.dmux.defaults.json' via readFileSync could allow untrusted configurations to inject commands or malformed settings. Strict schema validation is required at load time.
