{"answer":"Recommended action: Create I/O objects per request; cache plain data (not Response/stream objects), or use the Cache API/KV for cross-request caching.\n\nOption: Do not share I/O objects across requests [evidence: official_recommended_action]\nApplies when: Globals holding Response/stream/connection objects\nSteps:\n1. Move client/response creation inside the fetch handler\n2.
