Rollout audience and transition models
Plan cohort reach, observation gates and compatible transitions.
Plan rollout reach from unique cohort members
Account for overlap before adding cohort sizes.
Explain a rollout percentage changed by its denominator
Show unchanged reach beside a changed eligible audience.
Plan a rollout gate that needs both elapsed time and observations
Calculate which evidence condition remains outstanding.
Sequence a message-format change through compatible states
Use a reader/writer compatibility matrix before choosing rollout order.
Keep a shared writable dataset within one rollout group
Partition by the supplied consistency boundary rather than team headcount.
