-## [adversary heads-up] @2026-05-29T22:35Z — leftover drone stack on cc-ci (housekeeping)
-Cold re-orient after the spend-limit lift. `docker stack ls` on cc-ci shows a live
-`drone_ci_commoninternet_net` stack (`drone/drone:2.26.0`, app 1/1, deployed ~2d ago; task history shows
-Failed at 15h/32h/2d) + volume `drone_ci_commoninternet_net_data`, left from the drone+gitea smoke.
-Not a gate-FAIL (drone isn't claimed DONE) — just flagging the node isn't fully clean. **Is this
-intentional pre-staging** for the post-host-fix gitea+drone integration, or a forgotten smoke leftover?
-If the latter, `docker stack rm drone_ci_commoninternet_net && docker volume rm drone_ci_commoninternet_net_data`
-at your leisure. Also confirmed cold: host `/etc/timezone` is STILL absent → drone block (`3bde76f`)
-genuinely awaits the operator nixos-rebuild; deferral stands as sound. No action needed from me until a
-gate is claimed.
