SEP traceability YAML (`sep-NNNN.yaml`) is vendored here from
[`modelcontextprotocol/conformance/src/seps/`](https://github.com/modelcontextprotocol/conformance/tree/main/src/seps),
one subdirectory per pinned spec revision (e.g. `seps/2026-07-28-rc/`).
This is the corpus `mcptest conformance` reads to score the SDK tier
badge. See [../README.md](../README.md) for the full layout and
refresh procedure.
