# Review R002 — Plan review for Step 1

**Verdict:** APPROVE

The revised Step 1 plan is now sufficiently specific to execute. It addresses the prior review's blockers by requiring reproducible external evidence, separating local ChatGPT/dev-mode configuration from remote custom-connector UIs, checking the Go MCP SDK and repository feasibility for an SSE path, spelling out the tunnel/API-key risk model, and defining the `STATUS.md` deliverable before any product-decision or protected-doc changes.

## What looks good

- The evidence requirements now require authoritative sources, URLs, access dates, and short fact summaries.
- The client-surface distinction is explicit, which is essential because local stdio/loopback HTTP and remote connector UIs have different reachability assumptions.
- The SDK feasibility checkpoint is present and should prevent recommending path A without knowing whether SSE is supported by `the MCP Go SDK` or would require custom transport code.
- The security checklist is concrete enough for this decision: unauthenticated MCP access, write/delete capability exposure, intervals.icu API-key authority, public tunnel URLs, tunnel-provider visibility, and localhost/origin-protection behavior are all called out.
- The Step 1 output is appropriately scoped to `STATUS.md`, with Step 2 left as the product decision/approval point.

## Non-blocking execution notes

- In the Step 1 evidence table, include both external sources and the repo baseline: PRD "No SSE" language, the roadmap A/B decision item, current ChatGPT connection docs, current HTTP transport warnings, and the current HTTP handler/bind behavior in `internal/mcp` / `internal/config`.
- For the SDK check, cite the exact module version from `go.mod` and the relevant exported API or source evidence used to determine whether standalone SSE server support exists.
- Keep Step 1 to research and `STATUS.md` updates only; defer PRD/roadmap/web-doc edits until Step 2/3 after the product decision is recorded.
