# Review R005 — Plan Review for Step 2

Verdict: **APPROVE**

The Step 2 plan is appropriately narrow: since Step 1's raw Streamable HTTP JSON-RPC smoke tests already pass, no transport or server behavior changes are currently justified. The right implementation for this step is to verify the targeted MCP tests, update `STATUS.md` with the result, and leave `internal/mcp/transport.go` and `internal/mcp/server.go` untouched unless a failing test demonstrates a protocol bug.

## Required execution guardrails

- Do not change stdio behavior or HTTP binding defaults as part of this step.
- Do not switch response modes or rewrite transport wiring speculatively; preserve the existing behavior validated by the smoke tests.
- If a future failure is observed, keep any fix limited to strict JSON-RPC envelope preservation and short/actionable protocol errors.

## Verification

- Ran: `go test ./internal/mcp -run 'Streamable|JSONRPC|Codex|Protocol|Ping|Initialize' -count=1` — passed.

Proceed with Step 2 as a no-code verification step unless new failures appear.
