Suggestion: Sanitize or properly encode ANSI sequences before rendering to terminal, or use a robust TUI library that handles escape codes correctly

2. Final output shows garbled text with missing/corrupted characters making the success state unclear

Triaged as a bug — the ANSI escape sequence corruption and garbled output in the spinner likely stem from raw control characters being written without proper terminal handling. This is actionable and should be investigated in the CLI spinner/TUI code.

Security Triage

Issue Type: UX/Output Formatting Bug

Analysis: This is a legitimate UX bug affecting terminal output clarity during interactive sessions. The ANSI escape sequence corruption and garbled final output are straightforward display issues, not security vulnerabilities.

Security Assessment: ✓ Safe to work on

• No credential leakage or exposure
• No authentication/authorization bypass
• No injection vectors or unsafe deserialization
• Issue is localized to CLI output formatting and spinner rendering
• Root cause likely in TUI/terminal handling code

Recommendation: Actionable bug report. Recommended for priority-based work queue assignment.
