Shared backend library

This is a Go library module, not an executable. It provides database connections, transactions and repository primitives, errors, structured logging, generic HTTP responses, configuration and rate-limit helpers. It contains no customer, session, verification or Sendico domain models and imports no executable SXCHNGE module.

product consumes it through a local module replacement. A future backoffice executable can consume the same infrastructure independently.

Run go test -race ./... and go vet ./... here, or use the root Make targets to validate all implemented backend modules.

messaging/ contains the locally adapted Sendico NATS connection and durable transport adapters. Executables consume messaging/runtime; they do not open their own NATS connections. See notifications provenance for selected upstream source.
