Phase teams give estimates of the same project-wide helicopter service over their own time windows. Choose the maximum estimate on each day, then inspect what that reconciliation policy changes when a mast is added. This is an explicit policy, not formal sheafification.

Plan: Baseline
Change request (CR-07): Add a communications mast delivery+install window that overlaps the roof and utilities phases.
The mast team estimates the shared service at 4 flights/day on days 10–11, to accommodate steel and concrete.

Each phase proposes part of one shared helicopter schedule. Where two phases overlap, their proposed flight counts must agree to form one consistent curve.
