[plan] Validate improvements and monitor metrics post-deployment

[github-actions]

Objective

Validate that all fixes have been deployed successfully and monitor key metrics to confirm the expected improvements in agent health and firewall denial rates.

Context

After implementing the four preceding fixes, we need to verify that:

• Missing-tool errors are eliminated
• Firewall denial rate drops from 29.7% to <10%
• Build tool errors are resolved
• GitHub search errors decrease significantly

Approach

1. Wait for all parent sub-issues to be completed and merged
2. Monitor workflow runs for 48-72 hours post-deployment
3. Check Daily Audit reports for improvements in:
   • Success rate (maintain >85%)
   • Error volume (expect 30-50% reduction)
   • Missing-tool count (expect zero)
4. Review Daily Firewall Report for denial rate trends
5. Analyze workflow logs for recurring error patterns
6. Create a summary report comparing before/after metrics

Validation Checklist

• Daily Copilot PR Merged runs clean (no missing-tool)
• Copilot workflows show zero api.github.com denials
• Tidy workflow completes without build tool errors
• Issue Monster shows reduced search errors
• Weekly firewall denial rate <10%
• Overall success rate maintained or improved (>85%)
• Error volume reduced by at least 30%

Acceptance Criteria

• All metrics tracked for minimum 48 hours post-deployment
• Firewall denial rate confirms <10% weekly average
• No regression in success rate or new error patterns
• Summary report posted documenting improvements
• Parent tracking issue updated with final results
