API Security Hardening Sprint
March 7 was a security quality sprint across the ArgoBox API surface.
The work started from a broad site audit and turned into a practical cleanup pass: normalize API responses, reduce unnecessary implementation detail in client-facing errors, fix status codes that masked service availability, add request bounds, and improve RAG embedding behavior.
The important pattern was simple: the client should receive stable product behavior, while detailed operational diagnostics stay in server logs where they belong.
What Changed
- Public and admin API handlers moved toward generic client-safe error responses.
- Internal diagnostics stayed available server-side for troubleshooting.
- Several routes received more accurate HTTP status codes for unavailable services or invalid requests.
- Knowledge and ingest endpoints gained explicit request bounds.
- Shared response helpers reduced route-by-route response drift.
- The RAG embedder moved toward batched embedding behavior with stronger dimension validation.
Why It Matters
ArgoBox has a large surface area: public pages, admin modules, AI tools, service proxies, and RAG workflows all share the same deployment environment. Small inconsistencies add up quickly.
This pass made the platform more predictable and less chatty at the boundary. That is the kind of hardening that users rarely notice directly, but it is exactly what keeps the product feeling stable.
