What causes GitHub Actions environment variables scoping issues in monorepos?

Monorepos need per-app-per-tier envs for protection rules, but no wildcards force 100s of duplicate entries.

How to fix GitHub Actions env vars without wildcards?

Use a repo JSON var (ENVIRONMENT_CONFIG), jq to extract tier keys into $GITHUB_ENV on deploy.

Will GitHub add wildcard support for environment variables?

Likely soon—monorepo growth demands it; watch for 2025 updates.
