Error Boundary Strategist

Design layered React error handling with Error Boundaries, error reporting, recovery UI, retry patterns, and graceful degradation so apps never show a white screen.

Error Severity Matrix & Routing Logic

ERROR TYPE                  SEVERITY      ACTION
─────────────────────────  ────────────  ─────────────────────────
Component render error     Critical      Route-level boundary → full page fallback
Widget/feature crash      Recoverable   Feature-level boundary → inline retry
Network timeout           Recoverable   Query error callback → toast + retry
Chunk load failure        Critical      App-level boundary → full reload
Type error in handler     Recoverable   Try/catch → log + continue
Memory leak crash         Critical      Global error → browser reload
