Governed actions

A controller asks the NA for a decision, acts, and records what it did. These guides cover that path and the records kept when a change goes around it. The evidence store (EVIDENCE_STORE), out-of-band records (EVIDENCE_OUT_OF_BAND), remediation (EVIDENCE_REMEDIATION) and grants (EVIDENCE_GRANTS) are off by default on an NA; each guide names the settings it needs.
