ProxMenux Audit Routes
Flask blueprint for the Audit & Report assessment engine.
An assessment reads the host and records findings; it never modifies
anything. The run endpoint is therefore the only POST that does real
work, and it is deliberately serialised: two concurrent assessments would
compete for the same collectors without producing a better answer.
