Production rhythm and delivery checkpoints became visible

Why this matters

Managing production is not only about making a plan.
It also requires a clear historical record of changes, execution gaps, and completed checkpoints.

This round included

1. A clearer definition of key delivery checkpoints.
2. Archived screenshots and timeline notes.
3. A reusable structure for comparing later phases against this one.

Result

With dated records in place, it becomes much easier to compare different stages and review how delivery control improves over time.
