To understand where .env.default.local fits, compare it to the industry-standard .env files: Git Status .env General defaults for all environments (dev, staging, prod). .env.local
| Approach | Security | Onboarding Ease | Git Conflict Risk | Override Flexibility | | :--- | :--- | :--- | :--- | :--- | | | High (never committed) | Very Low (no defaults) | Low | High | | .env.example | High | Medium (manual copy) | Low | Medium | | YAML config files | Low (often committed) | Medium | High | Low | | .env.default.local | High (secrets stay local, defaults are safe) | Very High (works out of box) | None (local file is ignored) | Very High | .env.default.local
