Organise work packages into named transition architectures with dependencies and evidence gates so Phase F has a defensible migration plan.

Transition roadmap: baseline to target through operable states
Each state is a viable architecture that must run before the next begins. The arrow into a state carries the work packages that deliver it, and every column lists its packages with the evidence gate that proves the state is real.
A transition architecture is not a milestone on a slide; it is a state the business can actually operate. The evidence gate on each card is what the architecture board checks before the next work package may start.

State 1 is the active front: 1 package must pass its gate before state 2 can start.
Sequencing fault: 2 packages depend on work in the same or a later state. Move the dependency earlier or the package later.
