-# Dada 后续问题修改开发约定
+# Dada 开发约定
 
 ## 适用范围
 
-本约定在“Dada P0-A Windows 单机内测版”完整开发完成后生效，仅适用于该版完成后发现问题所产生的修改和相关工单；该版完成之前的当前第一版开发不适用本约定。
+本约定自当前“Dada P0-A Windows 单机内测版”第一版开发起立即生效，适用于任务计划中的每个 `TASK-*`，也适用于第一版完成后的问题修改和相关工单。
 
 ## 开发约定
 
+- 每个 `TASK-*` 或后续工单都是独立交付单元。完成测试与回归后，必须形成范围明确的本地 Git 提交，推送到 `intelligrow` 组织仓库的同名 Gitea 远端分支，并记录任务号、完整提交 SHA、远端分支和远端哈希核对结果。不得等第一版全部开发完成后再统一提交；本地未提交、推送失败、仅推送个人命名空间或远端哈希不一致时，不得宣告当前任务完成，也不得开始下一任务。
 - 修复任何工单必须在独立的 git worktree 中进行；开工前先用 `git worktree add` 创建专属工作目录，避免污染主工作区、便于多工单并行。修 CI 配置（Dockerfile、Drone 流水线等）可以直接在主仓库改，因为 CI 改动要打 tag 才能触发构建。
 - 处理任何工单必须先检查并使用适用的 Superpowers Skill；在分析、提问、制定计划或改代码前，至少先启用 `using-superpowers`，并按任务性质继续使用 `systematic-debugging`、`test-driven-development`、`using-git-worktrees`、`verification-before-completion` 等相关技能。若判断没有适用技能，必须简短说明原因后再继续。
 - 新功能需求类工单必须先使用 Superpowers 的 `brainstorming` 技能帮助澄清目标、约束和方案，再进入计划或实现；缺陷类工单必须先使用 `systematic-debugging` 技能复现问题并分析 root cause，再开始修复，禁止在根因未明确时直接改代码。

+### 1.6 任务级 Git/Gitea 交付协议
+
+`tasks.md` 中每个 `TASK-*` 是最小工程交付单元。每个任务在开始实现前建立独立的 `codex/<wp-task>` 分支；完成 Red、Green、所属门禁、回归和脱敏扫描后，必须形成只包含该任务及其必要文档同步的本地 Git 提交，并推送到项目指定的 Gitea 组织仓库同名远端分支。当前项目的目标组织命名空间固定为 `intelligrow`，个人命名空间中的仓库或分支不作为任务交付位置。
+
+任务交付必须记录 `task_id`、完整提交 SHA、Gitea 仓库、远端分支和远端哈希核对结果；记录不得包含凭据。推送后必须通过远端引用确认 Gitea 分支哈希与本地提交完全一致。只有本地测试 Green、必要真实/人工门禁齐全且远端核对通过，任务才可从 `green` 或 `externally_blocked` 进入 `passed`。仅有工作区改动、本地提交、推送失败、推送到个人命名空间或远端哈希不一致时，均不得宣告任务完成、工作包完成，也不得开始下一个 `TASK-*`。
