Summary

plan-lifecycle now tears down the resources that a plan created. Source request: DocksDocks/public#89.

• plan-contract.md: a new ### Teardown subsection after ### Archive. It covers tracking, compose stacks, After archive, Exit without a merge, Production resources, and Kept resources.
  • After archive: stop the processes and stacks that the plan started, then run git worktree remove and git worktree prune, then git branch -d. Teardown never uses --force, git branch -D, or --volumes.
  • Before docker compose down, teardown records the volume names from the container mounts. This record also finds anonymous volumes, which have no project label.
  • Local resources are development, and teardown removes them without a question. A remote production cleanup needs its own in-session question. A yolo invocation does not answer it.
• The Merge now option states the teardown, so a Merge now answer confirms the branch delete.
• The non-production target definition moves from Yolo runs to Steps, acceptance, and effects.
• plan-manager and yolo point to the contract's Teardown at archive and at every exit without a merge. They report Kept resources.
• The yolo run summary gets a ### Kept resources section. yolo no longer keeps the merged local branch by rule.

Verification

• node scripts/ci.mjs --plugin plan-lifecycle: all checks passed.
• Plan acceptance A1 to A8 passed. The plan issue records the results.
• Plan review passed in round 2. Code review passed in round 1 with one MEDIUM finding, which the issue comment records.
