-- Phase 4.2 — Datto RMM Overshell evidence pipeline.
--
-- Two tables:
--   1. rmm_settings — singleton row caching the discovered Overshell
--      component_uid + variable_name. Avoids re-discovering on every dispatch.
--   2. rmm_executions — full lifecycle of every Overshell job Pulse triggers.
--      Forever-retained: stdout/stderr (redacted), parsed evidence, audit
--      linkage, target/asset linkage.
