The between-rounds vhost purge computed which `servers/{http,https}/<domain>.conf`
files to remove from the domain, falling back to the hardcoded default
`infinito.example` when the DOMAIN env was unset. On a node whose
DOMAIN_PRIMARY differs (e.g. a .onion node, where DOMAIN_PRIMARY is driven
by INFINITO_DOMAIN), the purge computed non-existent filenames and removed
nothing, leaving stale vhosts. The next matrix-deploy round's health probe
then hit those orphaned vhosts as HTTP 502.
Fall back to INFINITO_DOMAIN (the dev harness' domain SPOT) before the
default so the purge targets the real vhost files on any node. Precedence:
explicit arg > DOMAIN > INFINITO_DOMAIN > default. Covered by 4 new tests.

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/*).
