In August 2025, guardian/giant delivered a maintainability-focused enhancement in the Neo4jManifest module. The Neo4jManifest Comment Clarification explicitly documents that the function re-runs external extractors that have failed, with no functional changes to behavior. Implemented via a targeted update to the manifest code in backend/app/services/manifest/Neo4jManifest.scala (commit 83bb6bcd8b61ce0c64f48094ced093db0d51643c). This work reduces ambiguity, improves onboarding, and lays groundwork for safer future changes.

January 2025 focused on increasing frontend reliability in guardian/giant by fixing health-check behavior and improving startup resilience. Implemented a health-check bug fix that removes the problematic --retry-connrefuse option and corrects curl retry semantics to avoid unnecessary retries when the backend refuses connections. Added a startup retry enhancement that enables curl retries on connection refused, helping the frontend boot successfully during temporary backend unavailability. These changes reduce false failure signals, minimize bootstrapping issues, and contribute to higher frontend availability.
