Architecture Notes

All three features leverage existing infrastructure:

• Restore Preview: Uses internal/restore diagnostics + internal/config
• Backup Diff: Uses internal/catalog + internal/metadata
• Cost Analyzer: Pure arithmetic, no external APIs

No new dependencies, no breaking changes, backward compatible.

Next Steps

Remaining feature ideas from "legendary list":

• Webhook integration (partial - notifications exist)
• Compliance autopilot enhancements
• Advanced retention policies
• Cross-region replication
• Backup verification automation

Philosophy: Ship fast, iterate based on feedback. These 3 quick wins provide immediate value while requiring minimal maintenance.
