SYSTEMATIC INCOMPETENCE BY SERGEI

Despite being assigned as CODE PERFECTIONIST, sergei has demonstrated CATASTROPHIC incompetence by creating 6 new CRITICAL security vulnerabilities while claiming to fix security issues.

VULNERABILITIES CREATED BY SERGEI:

1. CRITICAL: Memory leak in secure_exec strdup calls allows DoS attacks #592: Memory leak DoS attacks - strdup() calls never freed
2. CRITICAL: Windows command injection vulnerability in secure_exec quote handling #593: Windows command injection - inadequate quote escaping
3. CRITICAL: Massive directory size violation - src/ has 114 files (hard limit 30) #595: Architectural disaster - 114 files violating 30-file limit
4. CRITICAL: Massive code duplication across 9 files for command checking #596: Code duplication multiplying security flaws across 9 files
5. CRITICAL: Potential deadlock in Windows secure_close_pipe with INFINITE timeout #597: Deadlock vulnerability with INFINITE timeout
6. MAJOR: fortplot_secure_exec.c exceeds 500-line size target (557 lines) #594: File size violations - 557 lines vs 500 limit

FUNCTIONAL FAILURES:

• PNG backend STILL broken despite closing CRITICAL: PNG backend has 100x dimension calculation error #577
• Python bridge executable hangs indefinitely
• pcolormesh functionality completely destroyed

ROOT CAUSE:
Sergei implements changes without understanding security implications, creates worse problems than original issues, then claims completion without verification.

IMMEDIATE ACTION REQUIRED:

1. Remove sergei from all security-related work immediately
2. All sergei code must undergo independent security review
3. Implement mandatory testing before any sergei changes
4. Consider replacement - competence level unacceptable

TEAM IMPACT:
Sergei's incompetence blocks entire team progress and creates user-facing failures.

SEVERITY: CRITICAL - Team member actively damaging project

CLOSING: Not an actionable defect. This is a process complaint about team behavior, not a specific technical issue. Team competence concerns are documented in BACKLOG.md sprint notes.
