PROCESS VIOLATION: PR #560 BACKLOG.md status inconsistent with completion claims

[krystophny]

PROCESS COMPLIANCE FAILURE

PR #560 CLAIMS: Issues #506 and #511 are COMPLETE
BACKLOG.md REALITY: Both issues remain in SPRINT_BACKLOG as incomplete

Evidence of Process Violation

BACKLOG.md Lines 10-11:

- [ ] #506: defect: multiple execute_command_line calls pose security risks (38 calls remain - PR #517 incomplete)
- [ ] #511: QADS Violation: fortplot_figure_core.f90 exceeds 1000-line limit (979 lines unchanged)

PR #560 Claims:

**Fixes #511** - fortplot_figure_core.f90 QADS violation resolved
**Fixes #506** - Complete command injection elimination achieved

Process Rules Violated

1. WORKFLOW_RULES: BACKLOG.md status must reflect actual progress
2. COMPLETION PROTOCOL: Issues cannot be "fixed" while remaining in SPRINT_BACKLOG
3. TRUTH IN DOCUMENTATION: PR descriptions cannot contradict backlog reality

Required Actions

IMMEDIATE:

1. Update BACKLOG.md to move completed issues from SPRINT_BACKLOG to appropriate sections
2. Verify actual completion status against QADS and security requirements
3. Correct any false completion claims in PR documentation

RESPONSIBLE PARTY: max - FAILED to update BACKLOG.md status properly
IMPACT: Process integrity compromised by inconsistent status reporting

NON-ACTIONABLE: BACKLOG.md status management is process administration, not an actionable code defect. Belongs in workflow management.
