 * **HTTPS on many hostnames**: `mocked-backend.invalid` and the intake hostnames derived from it (`trace.agent.`, `config.`, `instrumentation-telemetry-intake.`, `debugger-intake.`...) are network aliases of its container. Its certificate is generated when it starts, for all of them, signed by the mitmproxy CA (`utils/proxy/.mitmproxy`) the senders trust.
 * **Remote config**: it serves the remote config backend by default (no config until a test sends one). Tests send configs with `remote_config.send_state`, which sets them on the mocked backend, then waits for the library to apply them. See [Remote config](../edit/remote-config.md).

The JSON configuration applies flag selection (`selected_flag_tags`, `selected_flag_key_patterns`) with the semantics of `ffe-system-test-data` `flag-selection/README.md`. `client.ffe_use_suite(name)` serves an `ffe-system-test-data` evaluation suite's UFC instead, matching tags from its `flag-tags.json`; `client.ffe_set_flag_selection_ignored_reason(...)` makes it ignore every valid, non-empty selection, as when production cannot load tags.
 * **Control endpoints**: under `/system-tests/`, never recorded, used by `MockedBackendClient` from the test runner.

 The shared `mocked_backend` fixture serves these protobuf responses. Import shared FFE constants and fixture helpers from `utils.mocked_backend.ffe`. On the server distribution endpoint, explicitly accepting `application/protobuf` selects protobuf, including in comma-separated `Accept` lists with a positive quality value. Wildcard-only requests and existing agentless provider tests continue to receive JSON.

+Use `mocked_backend.client.ffe_set_response` or `mocked_backend.client.ffe_set_responses` with `response_format="protobuf"` to configure these responses; the default format is JSON. Each format has an independent response timeline, and controls reject response IDs unsupported by the selected format. `mocked_backend.client.ffe_reset` resets both timelines and the shared request history, serves the root UFC again instead of an `ffe_use_suite` suite, and clears `ffe_set_flag_selection_ignored_reason`. Use `mocked_backend.ffe_get_requests` to inspect paths, queries, and headers without including fixture control traffic.
 
 The protobuf response IDs `selection_ignored_empty`, `selection_ignored_tag_load_failed`, and `selection_ignored_unknown` return the full rules fixture with a `DD-Flag-Selection-Ignored` header set to an empty string, `tag_load_failed`, or `future_reason`, respectively. Use these shared responses to test selection diagnostics without replacing the rules endpoint handler. The `valid` response omits the header.

+"""Server SDK flag selection against the mocked FFE agentless backend.
+
+Feature under test: a server SDK given a flag selection sends it on the agentless configuration request and serves
+only the flags the backend returns. The cases come from the ffe-system-test-data flag-selection evaluation suite: the
+mocked backend serves the suite's ufc-config.json and applies the selection with the suite's flag-tags.json. Each case
+file is one provider start.
+
+The test apps must pass the selection to the SDK as written, through ffe_start's flag_selection field, so the
+canonical selection on the request is the SDK's own work. The Node.js test app builds its provider at boot, so it must
+take the same raw selection from SYSTEM_TESTS_FFE_FLAG_SELECTION instead.
