The final lesson states the boundary: this is fixed-order deterministic balancing.
highlighted = computed this step
Fixed order
The packing keeps the fixed task order.
fixed-order deterministic packing
Not a global proof
This does not prove a global assembly-line optimum.
not a global optimum proof
Not modeled
It does not prove ergonomic feasibility, parallel work, or stochastic task times.
outside scope: ergonomics and uncertainty
Honesty note
This is fixed-order deterministic line-balancing arithmetic. It is not a proof of ergonomic feasibility, parallel work, stochastic task times, or a global assembly-line optimum.
