+Covers mcp.protocol.api_key.passes_official_conformance: the gateway is a

+official @modelcontextprotocol/conformance server scenarios (the same suite
+the SDKs gate their CI on) against a gateway-registered server backed by the
+stub's /conformance mount, which implements the suite's hardcoded fixture
+contract (test_simple_text, test://static-text, test_simple_prompt, ...).

+fallback that tools/call has is missing, so the suite's hardcoded prompt
+names 403), and binary resource read-through drops the base64 blob field
+(the stub serves it; the gateway's answer has no blob).

+"""Live e2e: the MCP gateway's prompt and resource primitives.
+
+Covers mcp.list_prompts.api_key.succeeds, mcp.get_prompt.api_key.succeeds,
+mcp.list_resources.api_key.succeeds, and mcp.read_resource.api_key.succeeds,
+against the stub's /conformance mount (tests/e2e/mcp/stub/), the one upstream
+that serves all three MCP primitives.
+
+The gateway's namespacing contract differs per primitive, and the assertions
+pin it exactly as observed live: prompt names are alias-prefixed like tool
+names (and must be fetched by the prefixed name), while resource URIs pass
+through unprefixed (only the resource's display name gains the prefix). The
+prompt-rendering assertion feeds unique per-run argument values through
+prompts/get and requires them back verbatim in the rendered text, so a cached
+or canned response cannot pass; the resource assertion requires the exact
+fixture body.
+
+The binary-resource read (test://static-binary) is deliberately NOT asserted
+here: the gateway currently drops the base64 blob field on read-through
+(verified against the stub directly, which serves it), and that gap is pinned
+in the conformance suite baseline (test_mcp_conformance_e2e.py) instead.
