A typed API client base (JSON + ETag + ProblemDetails translation), a Polly-based resilient HttpClient registration helper, and a generic cached-token provider for worker-to-API auth.

OIDC token forwarding, refresh, caching (with optional Redis backing for multi-instance deployments), and a client-credentials fallback for interactive Blazor Server applications.

An auditable-entity base + TimeProvider-driven SaveChanges interceptor, a Postgres advisory-lock-guarded migrate-on-startup helper, a snake_case entity/column naming convention that leaves the... More information
