## Implementation report

実装報告:
- Orchestrator role prompt の workspace routing context に、implementation worktree の配置先と branch base を分離して明記した。
- Orchestrator worktree routing prompt に、implementation branch は Orchestrator workspace current HEAD / orchestration branch HEAD から切ると明記した。
- Merge completion prompt に、implementation branch -> orchestration branch -> merge target の順序を明記した。
- client prompt generation test に branch base guidance の assertion を追加した。

検証:
- cargo fmt
- cargo test -p client ticket_role
- cargo check --workspace
- nix build .#yoi
- git diff --check
- target/debug/yoi ticket doctor

<!-- event: close author: hare at: 2026-06-12T08:15:54Z status: closed -->

## 完了

Orchestrator が implementation worktree を original workspace 配下に作成する場合でも、implementation branch は Orchestrator workspace current HEAD / orchestration branch HEAD を base とするよう、role prompt / routing prompt / merge completion prompt に明記した。検証は cargo fmt、cargo test -p client ticket_role、cargo check --workspace、nix build .#yoi、git diff --check、target/debug/yoi ticket doctor で完了。
