PRD 0018 chunk 2. Each sidecar's prepare-time output (pipelock yaml + CAs, egress routes.yaml + CAs, git-gate entrypoint + hooks, supervise current-config, agent env + prompt) now lands in ~/.claude-bottle/state/<slug>/<service>/ instead of an ephemeral mktemp dir. The state subdirs become the stable bind-mount sources that chunk 3's docker compose project will reference. The SDK launch path is unchanged — `docker cp` still copies from the plan-held paths into containers, just from new locations. start.py's session-end cleanup is now in `finally`, which also reaps state dirs left behind by dry-run / preflight-N / prepare-exception paths (previously only the post-launch path settled state).
