需求：为客户端修复任务建立独立 worktree 所有权与项目记忆门禁。

实现：引入标准 .project-docs 模板，不修改现有客户端业务代码。

+# Planning Gate
+
+A coding agent must complete this gate after the Concurrent Task Gate and before writing an implementation plan.
+
+## Peer Scope Check
+
+Run `task_context.py status --json`. For each other owner, read only the peer task record at `Path(owner.worktree) / owner.task_record`. Use its `Scope`, `Intent And Constraints`, and `Promotion Candidates` sections to assess overlap.
+
+Do not inspect or modify arbitrary uncommitted files in another task's worktree. Report a missing or unreadable peer record as unknown coordination state; do not silently treat it as no overlap. Code-path overlap alone is a warning. Block when semantic decisions conflict or unresolved overlap could change the plan.
+
+## Required Output
+
+```md
+## Project Context Loaded
+
+Task context:
+- Task ID:
+- Mode:
+- Branch:
+- Worktree:
+- Base commit:
+- Other active local tasks:
+- Overlap or semantic-conflict assessment:
+
+Read:
+- {file path}
+
+Relevant understanding:
+- Project goal:
+- Current integrated focus:
+- Active task scope:
+- Active constraints:
+- Decisions affecting this task:
+- Evidence, reflections, or commitments affecting this task:
+- Files or modules likely involved:
+- Unknowns, stale docs, or conflicts:
+
+Gate result:
+- Passed or Blocked
+```
+
+## Pass Criteria
+
+The gate passes only when:
+
+- task identity and worktree ownership are resolved
+- the active task record exists and matches the owner task ID
+- required documents were read
+- task-relevant decisions were checked
+- relevant evidence, reflection, and commitment indexes were checked when applicable
+- other active local task scopes were assessed
+- stale, unknown, or conflicting context was called out
+- the plan respects project positioning and constraints
+
+## Block Criteria
+
+Block planning when:
+
+- worktree ownership is unresolved
+- an unowned worktree is dirty and has not been explicitly adopted by a human
+- required worktree isolation failed or later operations cannot remain rooted there
+- required documents are missing or a concurrency upgrade is incomplete
+- current integrated state conflicts with the user request
+- an existing decision appears to be violated
+- semantic decisions conflict across active tasks
+- the task changes project positioning or architecture without human confirmation
