A security team can have enough people on a roster and still be underprepared. The difference is whether each person understands scene safety, escalation thresholds, and what must be recorded before an incident becomes a dispute.
JTF Academy treats safety as a credentialed operating habit. Course completion can write into JTFID, and downstream roster checks can read that status before a person is placed into work.
That is the practical reason the course catalog, Passport, roster, and command layer are connected. Training is not a PDF archive; it is an input into real deployment gates.
