Safe AI companion for kids — regulated-environment design
Per-child AI companion with parent-configured age bands (5–8, 9–12, 13–17) and a
three-layer safety stack: homoglyph-normalized regex classifier → Claude-Haiku
LLM input classifier → output verifier with fail-closed crisis fallback.
PBKDF2-SHA256 parent PIN, per-profile rate limiting, alert dedup, sanitized error
paths. Designed from day one around COPPA + state minor-safety law — same
regulated-environment mindset that translates to ITAR / AS9100 work.
