How msferraresi/service_doppel works

ServiceDoppel is a configurable HTTP mock hub: callers send requests to a catch-all route, which matches an active service endpoint, selects a response scenario, records the request, applies configured latency, and returns the scenario response. The SQLite-backed configuration describes services, endpoint patterns, and scenarios; a seed routine provides an example setup. Relationships below are limited to those shown in the excerpts or source index; the README is empty, and unshown administrative capabilities are not inferred.
