SimulatedAnnealing (and SAMIN) claims "Status Failure", but output seems to be OK?

You are correct, running the example from the documentation at https://github.com/JuliaNLSolvers/Optim.jl/blob/master/docs/src/algo/samin.md

using Optim, OptimTestProblems

prob = UnconstrainedProblems.examples["Rosenbrock"];
res = Optim.optimize(prob.f, fill(-100.0, 2), fill(100.0, 2), prob.initial_x, SAMIN(), Optim.Options(iterations=10^6))
println(res)

I also see

Furthermore the documentation and current reporting differ and in the documentation I miss the status information signalling success or failure.
