SEP-2567 is merged into the draft spec: protocol-level sessions and the Mcp-Session-Id header are removed from Streamable HTTP, and the list endpoints (tools/list, resources/list, prompts/list) are connection-invariant (see the draft changelog).
The suite has no coverage for it yet: there is no src/seps/sep-2567.yaml, and no scenario exercises the sessionless invariants at the draft revision.
We should add requirement traceability and a draft-suite server scenario, following the sep-2575 pattern (sep-2575.yaml + ServerStatelessScenario).
Related: #222 covers the 2025-11-25 "server MAY omit Mcp-Session-Id" path at the dated spec versions; the draft revision removes sessions outright, so that work is complementary.
