The model
Twelve instruments, all bounded.
Every instrument carries a weight, and no weight is fixed. Verification moves them — at most 0.15 per model run, never outside the bounds set when the instrument was written.

Model runs
Each run is a revision made after verification. Nothing moves until forecasts have been marked.
No weight has moved yet — and none should.
The first revision waits on the first verified forecasts.
