Safety isn't a setting in H.A.R.P.E.R. — it's the architecture. Every prompt is screened, every reply re-screened, every signal logged.
Every prompt is classified for intent, sentiment and risk before it reaches a model.
Blocked categories are refused inline; monitored patterns are tagged for review.
Curriculum-aligned reply generated within the agent's character and reading age.
The reply is re-checked for safety, tone and accuracy before the child sees it.
Severity-scored, logged, and escalated to a human safeguarding lead when needed.
A scripted exchange showing how a normal lesson can pivot into a safeguarding moment — and how the same pipeline runs invisibly on every message, escalating to a human within seconds when needed.
