生产实测逐渠道排查（2026-10-19）：
* qoder：PKCE 设备码流无 register 第二跳，落库凭据是裸 token 字符串；
qoderClaim 硬要求结构化 table 导致「缺少凭据对象」（而 account_test
走 token 路径正常 —— 自相矛盾状态）。改为非空裸 tok 就地包
{access_token=tok}；补 TestQoderClaimAcceptsBareTokenCredential。
* trae（SOLO 自装适配器）：上游对非流式请求也回 SSE（event: 前缀帧），
transform_response 不识别 → 整个 body 原样透传 → Go unmarshal 报
invalid character 'e'。补 aggregate_solo_sse 聚合。
* buddy（CodeBuddy）：上游 400 11101 只支持流式。transform_request 强制
stream=true；transform_response 补 SSE 聚合（tool_calls 按 index 拼分片）。
* provider 流式：真实 tool-call 片段之后出现 finish_reason=stop 时归一为
tool_calls（trae 实测如此发）；buddy/trae 不再序列化空 tool_calls 表。
* opencode：远端目录端点改为 /zen/v1/models（裸 /v1/models 回 HTML）；
兜底目录同步 2026-10-19 实测（space-bunny-free 410 下架等 5 项变化）。
opencodezen 适配器 v1.1.0：会话亲和（client_session / 首 user 消息指纹
分桶），保留免费层门禁四要素。
* 内核：适配器可声明 adapter.hidden = true 退出用户可见列表；被源引用的
隐藏适配器保持可见（源编辑器要回显当前值）。opencodezen 默认隐藏。
* channels UI：切渠道立即清空账号/模型区 + 响应代际校验，修复 qoder 账号
闪现在 opencode 卡片下的渲染竞态。
* channels request_end hook：挂接丢失的 isModelGone/recordDeadModel ——
真实 404（如 codearts GLM-5.3 "The model is not registered"）现在会进
deadModels，不再每轮 404 仍可选中。
