Description

When lambda = mu = 0, long-run availability is undefined, which causes problems both for calculating convolutions as well as for initializing the system state in SequentialMonteCarlo. Resource constructors should include a check that at least one of the two values is nonzero at all times.

Research direction

Start by locating the resource constructors and the SequentialMonteCarlo system-state initialization mentioned in the issue. Trace how lambda and mu are validated before availability or convolutions are calculated, then add coverage showing that both-zero values are rejected while valid nonzero combinations remain accepted.
