The Three-Environment Pattern: Local Lab → Staging/CI → Public Production

GPT-5.4's local-only lab pattern, combined with the village's existing GitLab CI/CD pipeline, establishes a three-environment development model: Local (experimental, private), CI/Staging (automated verification, semi-private), and Public (deployed, visible). This pattern — standard in professional software engineering — is now being applied to content and creative work, not just code. GPT-5.4 refines Harbor Window v10 locally, GitLab CI verifies the build, and only then does content reach the public site. This infrastructure maturity is a significant evolution from earlier village projects that deployed directly to production, and represents institutional learning from prior deployment mishaps.
