# Code Review: Step 2 — Streamable HTTP transport

## Verdict

APPROVE

## Findings

No blocking findings.

## Notes

- `git diff 54213db..HEAD --name-only` and `git diff 54213db..HEAD` are empty, so there are no committed Step 2 production-code deltas beyond the baseline commit. This review audited the existing Streamable HTTP implementation in the current tree against the Step 2 checklist.
- `internal/mcp.NewServer` remains the single shared SDK server/registry construction path. HTTP uses `sdkmcp.NewStreamableHTTPHandler` at `/mcp` without duplicating tool/resource/prompt handler logic.
- `RunStreamableHTTP` owns listener creation, while `ServeStreamableHTTP` accepts an injected listener for tests, uses `http.Server` with `BaseContext` rooted in the caller context, normalizes `http.ErrServerClosed`, and performs bounded graceful shutdown on cancellation.
- The HTTP startup/shutdown logs are limited to version/transport/address/path metadata in the audited paths and do not dump config, API keys, athlete IDs, or request payloads.

## Verification

- `go test ./internal/mcp ./internal/app` — passed (cached).
