An image bump in a provider redeployed every variant of every consumer, including the variants that switch that provider off and therefore never deploy the bumped image at all. The diff-derived whitelist now narrows each affected role to the variants whose own round closure still reaches a seed, emitted as `role#0,2` selection tokens. That closure is walked on the same variant-merged services maps the matrix planner builds its rounds from, so the narrowing follows a parent's variant choice across every generation of the chain. It covers every auto-derived whitelist: the weekly update PRs, Dependabot, and any other diff-driven run. The narrowing never shrinks the matrix on partial information. A seed role keeps every variant, because its own files changed. A role reached only through a run_after edge keeps every variant too, because the round closure does not follow that edge and a role whose hits are empty is therefore unnarrowed rather than dropped. A pinned token naming a role the discovery query does not return now warns instead of aborting the run. The diff-derived whitelist legitimately names roles the lifecycle envelope filters out, and once it pins variants such a token would abort every chunk; role names are still checked against roles/ before the run starts, so a typo is caught one layer earlier. The round's variant merge moves out of the deploy inventory package into utils/roles/applications/variants.py. The CI selection has to build the same maps, and importing the deploy package for them pulls in a module that reads INFINITO_SRC_DIR at import time, which the runner host does not set.

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/*).
