Reference · the decision library

The decisions that have no arithmetic.

The engines compute, and the rulebook shows the working. That covers the decisions with a method. It covers none of the ones that get argued about — chicken wire or foam, who arrives when, what comes out when the number is fifteen percent over, whether the weather call has to be made now.

Those have named trade-offs rather than answers. A matrix compares options that all remain available, scored on the same criteria so the comparison is like-for-like. A flow is for a question whose answer depends on facts you have to go and establish, in order, where the first no is the answer. Neither carries a total or a recommendation, because the weights belong to your event and this library has never met it.

None of this is a rule

Nothing on this page changes a figure inside Atmosphere OS. The engines do not read it, the ledger does not cite it, and a plan produced with this library empty is identical to a plan produced with it full. It is here to make an argument visible, not to settle one — and where an outcome names somebody else's sign-off, that is the answer rather than a caveat attached to it.
