30-60-90 structure

Day 1-30: baseline and instrumentation
- lock metric definitions
- collect baseline values
- define red/yellow/green thresholds
- start weekly scorecard
Day 31-60: scenario and correction loops
- test conservative/base/aggressive assumptions
- remove the top two bottlenecks
- document before/after change impact
Day 61-90: scale with controls
- scale only proven actions
- enforce audit gate before expansion
- keep rollback path explicit
Primary execution focus: baseline inputs and weekly recalculation.
