Side B is a solid correctness improvement—changing feed catch-up to use durable ingest order instead of timestamps, enforcing room visibility during feed generation, and adding regression tests—but it is a targeted behavioral fix rather than the broad persistence and scalability architecture added in Side A.\"}","refusal":null,"reasoning":null,"reasoning_details":[{"type":"reasoning.encrypted","data":"gAAAAABqXVE98MYoI5kunVmnaLd0XBgDnaYFEK_SM6uyfzNSci1BP7d4_rYHOjTQQbZ8xUOJGsxYwCi7HGuJC3F-9-ypySvH6-flzZh-nnY_ZDZntc5p80GQ-A27bYc7o5TL01wm-6HBFxgSr7i-Nu8vXe7X7rd5xx--X-nrwN0LpkYEMe4MMtzer-TZpfoD4HnmMJfJTuOhqIMgWFIxx8lpga9XJRMu_m4qX1m8cWzPUGrWvXaAiJ0B9EhQj-XsTXAVAnSjaD9QR3IYUW3At8ZHIRsJ461sSOjFKOPliDk2eiA0csf3qyqbjWkM0KFL6B0QVZBK4KW697ybH1C4tjRhGVRXyaCFBt1RQucQcz9ZMCYXt4uEB-OKemadtJkvy9wVsWZ8kREa9VH9UCCDiQIfOfKHfnl13dZcdzzh4vvi-aUfpobCfAbLB-QvAE1PNBcrb5A0ATABJCrjDg5GiQGIS4jwtAlxUafOmrwRN8cSR1HVFDrkWp2xEHkkte-apg2JVrIFhuR0mVRZ-5nrhclgSliLi-_6tlbE37dsVdO9_4VDtewZSz_T1JWZBZZUDRFR3lI54y0TpwE8Ko79TNwg_cQI3wck1sb1_APyma-rFa7F0CIURqEnjYi1yMnGbJKrFsRaBYfnAIlvZNZwyI6WiBA0nJeQX2ghRrC9MmZ1BxY7P7K9bYosn7OkPy49_JmRRxqKe22higNrEpWXKRHeC0KaMByjTIP36vZsFZIixjCERsgD8LrSVg5UO6vDAHWZcHCLA_uTjLK30HL68joy2-kIlfsuueBzqZ1h4vJGEP8hM_au6MFvUmGukNYw4r0yaTmPne_9-6CQdMQRkpu_Ahhh4hl8FIa2amRKk_FVZ2cTcw5kMdV_0mkXitu0lEwnPTq57vNJvoGxHvXv_8s9zWLHwILTxo6z6natBUNiwOx413iC0n44fduYv_DHXCXMfmMSFmRsiRVelD_dmySYduDoSo-tY6927DLc35Nj9E9aigT4B7Q=","format":"openai-responses-v1","id":"rs_0d8b49980be8d01d016a5d513d11d8819db3aa89cda1f7a6fe","index":0}]}}],"usage":{"prompt_tokens":70419,"completion_tokens":148,"total_tokens":70567,"cost":0.356535,"is_byok":false,"prompt_tokens_details":{"cached_tokens":0,"cache_write_tokens":0,"audio_tokens":0,"video_tokens":0},"cost_details":{"upstream_inference_cost":0.356535,"upstream_inference_prompt_cost":0.352095,"upstream_inference_completions_cost":0.00444},"completion_tokens_details":{"reasoning_tokens":0,"image_tokens":0,"audio_tokens":0}}}
