How the gate runs

Predictive
Phase gate: held once, at the end of the stage.
Agile (iterative)
Rolling gate: held per release; item readiness via Definition of Ready, completion via Definition of Done.
Flow (Kanban)
Policy gate: explicit exit policies on the board columns, applied to every item.
Hybrid
Phase gate per phase, with iterations or flow inside the phase.
