dev-workflow-skills2 Stage 6 Delivery 写作 vertical skill。在 progress.md current_stage==delivery AND sub_state ∈ {write, revising} 时被 invoke。负责写 delivery/deployment.md、operation_manual.md、installation_result.md，并执行安装/部署验证，installation-result.verification_status 必须记录 pass/fail/partial。完成后 validate 三份 one-shot docs 并调 progress.py update --event write-complete 交给 delivery-review。本 skill 不进入 Bug Flow、不修上游 baseline、不直接 mutation progress.md。
