Every app's compose pass ran three remote tasks before compose up: create the directories, compose ps for running containers, and stat the pending marker (53 apps x ~2.7 s in a production run). compose_instance_prepare does all three in one call from 02_stack_host_prep.yml, sharing the directory creation with directory_batch through utils/directory_batch.py; compose ps runs only in compose mode. up.yml evaluates the registered result, named compose_instance_before_files because it predates 04_files: the running check is skipped whenever the compose, env or override file changed in this run (those changes notify compose-up themselves).
Replay harness old vs new: rendered files and the compose-up, marker and swarm handlers identical in every scenario; the only difference is the skipped running check when only the override changed, where compose-up still runs. About 85 s per full production run.
Merge note: store-i18n's a4c7fda974 hoists the removed marker stat into a block; resolve up.yml with this side.
