These changes centralize item identity and routing logic (for example `RouteContext::item_href` and `ThreadNav::garden_item_href`) and reduce string-based handling. Side B adds useful deployment artifacts (Dockerfile, Fly config) and standalone persistence utilities (`EventLog`, `ViewStore`), but they are largely additive infrastructure and are not integrated into the project's core behavior in this patch.\"}","refusal":null,"reasoning":null,"reasoning_details":[{"type":"reasoning.encrypted","data":"gAAAAABqXEMnE_mG9F5kms8dmjm0g5I-UHYgp7RdM1BTNzbXA2061Wp_sg6FETjOS6XYR5REGdSuB-EoM2OW8vA6PJzst7BXe0dp4Hq6L-vRHYrLTRgm-9E7b0x-fDjM0EsCnlupt-rNG_9EUWq8k3i-qman4e7vlCv5zgljHS7Z8cGhJY8DPCGQlTAu-62urBE1pV6GQUC1K9YigTe4tjitlJK2KTz3aEnSH3Ue_Le7vWoGryz-OhPUMWV-S3-0LlPsfT2ewgiFy0sZjdogBSMIndAEhyH-c7IFs6pKhhViUWadFBA5BjsxKhSW78A1LTbh0iTikIUgh5AOEb0gC0xA7TP1ASt0SmKQtqcEwhLhH3SB-3iRqxJzgihmXcD7y4a7zJRDfV-JCIGQXzwdAxi8Nrw95jX2iQCZ5QxuVYbFYlEt8nAO6DErGYXUa3Z5WyLHKcbJT4ZHLdAOGqGV_RBvQL-nwjifDmOF7vDU-HOh-57B5MZaa1D2p5I48x4oVw0ZaxUBSHooaaPpc0h7V8svkyuBQQyV-fNErFo73qhM7gtaeoRFQfd0tCHry6n6imT7oGg7mGkaPBW_YO3QXB0b_bTv8GQnzxgGyYKji0O28sQ_groB79uyqhT9X3v7SPUFIQdv_gQPsrKKXid_rpEbXhJpsdgkJbf31axcV_0i_hSmDowjuHN6tsGL5RuA6Sc8AVORYv8mGcspy-_cs2HzlmPOj7YuSlJRMMQsYXoZSd2osbBf1ZRsKMveXjUBsskFgPTM49EVPCHkgV3h810oVbhwTeDlowVuATi5eKhJakGdR2-vHarYaxu5JaQ-STD6FrPvLYhPHbDpYiHoNA5GLin5nqy_wDIdGs7RSvhiGY8vzEP3Zw6HOMQ1e5Skl0hkJFDEW48vaw6rZRUB_KTqyeJuon_G1EJGkd5BZ2N14RWZ-GM_4dg=","format":"openai-responses-v1","id":"rs_0fa2542b9431cff3016a5c4326f8108194a746ede23d080996","index":0}]}}],"usage":{"prompt_tokens":32898,"completion_tokens":159,"total_tokens":33057,"cost":0.16926,"is_byok":false,"prompt_tokens_details":{"cached_tokens":0,"cache_write_tokens":0,"audio_tokens":0,"video_tokens":0},"cost_details":{"upstream_inference_cost":0.16926,"upstream_inference_prompt_cost":0.16449,"upstream_inference_completions_cost":0.00477},"completion_tokens_details":{"reasoning_tokens":0,"image_tokens":0,"audio_tokens":0}}}
