ODP Agent discovery

This example uses the Go Agent package to inspect live ODP Services, list terse Offerings, and fetch each Offering's full details. It also searches mixed Directory results and retrieves live details for Collection results through their owning Service.

The example composes a mock directory from the reachable Service origins supplied on the command line. The mock is isolated in mock_directory.go; it is not the canonical ODP directory and does not imitate directory ranking, filtering, facets, or suggestions. It samples at most two Collections from one response when both listing and detail operations permit anonymous access. This is local example setup; the production Directory indexes explicitly submitted Collections without crawling catalogs. Synthetic HTTPS origins in the mock map to the supplied local Service clients, so no requests are sent to those example domains.

Start the small Service in one terminal:

go run ./examples/odp-service-small

Run the Agent in another:

go run ./examples/odp-agent-discovery

The Agent probes http://localhost:4101 by default. Supply one or more Service origins to query a different set:

go run ./examples/odp-agent-discovery \
  -service http://localhost:4101 \
  -service http://localhost:4102

Unreachable candidates are omitted before the mock directory is created. The output identifies the Service, prints its validated ODP Service Document, prints each terse Offering returned by catalog navigation, and then prints the corresponding full Offering response. Mixed discovery prints each Service name and the full details of sampled Collections. Collection sampling errors are reported instead of silently presenting the sample as complete.
