The multiplication with -4 introduces additional allocations. I wonder if this could be avoided, e.g., by updating in-place or some additional cache.

Dealt with now (in-place scaling of tmp)

norm_plan is never updated it seems but always set to sum(plan) of the initial randomly initialized plan?

Maybe also avoid allocations here by writing:
| isconverged = sum(abs, plan - plan_prev) < max(_atol, _rtol * norm_plan) | |
| plan_prev .-= plan # used as a temporary array here to reduce allocations | |
| isconverged = sum(abs, plan_prev) < max(_atol, _rtol * norm_plan) |

The initial plan is taken to be the independent coupling and here we only consider the balanced problem, so norm_plan should not change. I agree however this is a special case of the unbalanced problem where it would not be constant.

Good catch, done
