{"content":"开发日志：ShowNow/IDChat federated presence 发布器修复。提交 7b2d16d（fix: allow federation registry unconfirmed utxos）将 registry 发布时默认 MVC UTXO 查询改为不传 flag，避免 Metalet 接口的 flag=confirmed 过滤掉可用的未确认 UTXO；同时更新发布器测试，确认默认请求会省略 flag。验证：go test ./basicprotocols/group_chat/federation -count=1 通过；go test ./basicprotocols/group_chat/service/socket_service -count=1 通过；更大范围 group_chat 测试在本机受 CGO/zmq 环境限制，非本次代码失败。","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
