Auth failure matrix

An auth failure matrix is a small table that separates missing credentials, invalid credentials, expired credentials, insufficient permission, and blocked environment before a developer changes code.

It is useful because 401 and 403 errors often look like one problem in a UI but require different fixes. A 401 usually means the request could not be authenticated: missing token, malformed header, expired session, wrong audience, or clock drift. A 403 usually means the caller was recognized but not allowed: wrong role, disabled feature flag, tenant boundary, resource ownership, or policy rule.

A good matrix records request path, method, caller identity, token source, token age, expected scope, actual scope, resource owner, environment, and exact response body. It should also include one known-good request so the team can compare headers and claims instead of guessing.

The boundary is that the matrix should not store secrets. Practical interpretation: record token metadata, redacted claim names, and permission checks, not raw tokens or private credentials.
