database Policy
Policy for what to do with <analysisName>.db when it already exists on disk at the start of a Simulate.
KSL's database schema rejects re-inserting SimulationRun rows whose experiment names collide with rows already present (and a re-run of the same document has identical experiment names by construction). So there is no "append to existing database" option — re-running means replace or side-by- side. See DatabasePolicy for the two outcomes.
