- Startup explanations needed to distinguish automated installation from removing installation work before launch.

Remaining: Live AWS diagnostic execution was outside scope; commands are illustrative.; HTML integration, glossary entries and full-project acceptance remain with the parent and later passes.

## Iteration 11
- Existing chapters lacked quantitative treatment of weekly backups versus a one-day RPO and three-hour restoration versus a one-hour RTO.

Remaining: Diagnostic commands are illustrative; no live customer infrastructure was tested.; Photographed incident prerequisites remain explicitly conditional.; HTML integration, glossary and full-project acceptance remain with the parent and later iterations.

## Iteration 13
- Application-defense questions needed precise distinctions between code fixes, WAF inspection, session protection and network segmentation.

- The older 14-principle poster needed a sourced distinction from the current 16 principles.

## Iteration 18
- The existing leadership fragment omitted all eight assigned principles.
- Quiz connections needed to preserve actual scenario constraints and truthful self-report interpretation.

The runner must record iteration 20 after accepting this report; execution state and global ledgers were not edited.
