@cognicatch

Production-grade React error-boundary infrastructure built for generative-UI applications. Provides AIBoundary for catching LLM hallucinations and malformed JSON payloads, BannerFallback, ModalFallback, and ToastFallback recovery UIs. Features zero-PII client-side scrubbing (emails, JWTs, API keys, credit cards redacted before telemetry), OpenTelemetry/OTLP vendor-agnostic error forwarding, and WCAG-compliant focus traps. Free for manual mode; API key required for managed telemetry. Use for: wrapping AI-generated UI trees so runtime crashes degrade gracefully instead of showing a blank screen.
