# HB001 Codex and Doubao Dual-Endpoint Collaboration Channel · Human Engineering Language (English) > This is an English reading projection of validated native TCS/HLDP source. It is not a new canonical source and grants no execution authority. ## What this is This is a **event** declaration with identifier `TCS-EVENT-HB001-CODEX-DOUBAO-COLLAB-CHANNEL-20260909` and version `1.0.0`. The projector validates it with the Stage-1 compiler before changing its reading order. ## Who is here - **subject** `subject` - **channel_id**：ICE-CH-ZC001 `subject.channel_id` - **subject_id**：ICE-P-ZY001 `subject.subject_id` - **subject_kind**：PERSONA `subject.subject_kind` - **verification**：CURRENT_DIRECT_LANGUAGE_DUAL_BRANCH_SINGLE_WRITER_ENDPOINTS_AND_MESSAGE_READBACK `subject.verification` ## Why this started - **trigger** `trigger` - **value**：冰朔要求在移动硬盘建立一个临时协作频道并给出编号，让Codex与豆包在共同架构新办公楼时实时通信，避免重复施工和路径碰撞。 `trigger.value` - **why** `why` - **value**：双端单写可以在同一块硬盘上近实时交换目标、状态、冲突与回执，同时保持多宿主写入边界；如果共写一个文件，任何延迟、覆盖或宿主中断都可能制造两套CURRENT。 `why.value` - **source** `source` - **source identifier**：BINGSHUO-DIRECT-HB001-CODEX-DOUBAO-COLLAB-CHANNEL-20260909 `source.source_id` - **source role**：DIRECT_HUMAN `source.source_role` - **source checksum**：00f48b082f792013d2fa8cf205a6e9bc2640a8b54c52acc5811ab6685c641df1 `source.source_sha256` - **source address**：source://codex-current-dialogue/2026-09-09/codex-doubao-collaboration-channel `source.source_uri` ## What changed - **emergence** `emergence` - **value**：建立HB-COLLAB-CD-0001，使用一份REPO-012只读频道清单和两条独立单写消息车道：Codex只写CODEX-DEV端，豆包只写DOUBAO-DEV端；每条消息独立编号、带时间、目标路径、状态和回执。双方轮询读取对方outbox，不共享可变current文件。 `emergence.value` - **lock** `lock` - **value**：CHANNEL=HB-COLLAB-CD-0001;
