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.

Shared Utilities (utils/)
This directory contains shared Python helpers used by custom modules and plugins.
Purpose
Use utils/ for reusable code that should not be duplicated across:
library/modules,plugins/action/,plugins/filter/,plugins/lookup/.
Typical shared utilities:
- API clients,
- validation/conversion helpers,
- path and configuration helpers,
- cross-plugin/module domain logic.
- Shared HTTP(S) connection handler for multiple modules.
- Common validation or transformation functions for user input.
- Utility functions for interacting with Docker, LDAP, etc.
- Grouped helper packages such as
utils/domains/for related domain logic.
Design Guidelines
- Keep helpers focused and composable.
- Avoid side effects during import.
- Prefer explicit function/class APIs over implicit globals.
- Keep dependencies minimal so modules/plugins stay lightweight.
Example Import
from utils.domains.primary_domain import get_primary_domain
What Does Not Belong Here
- Standalone executable modules (put in
library/). - Ansible plugin entrypoints (put in
plugins/*).
