+- ✅ **MCP server wrapping `query`** — shipped as `codemap mcp` (agent-transports v1) in PR [#35](https://github.com/stainless-code/codemap/pull/35). Tool taxonomy, output shape, and resource catalog reserved for HTTP API to inherit. See [`research/fallow.md` § Status snapshot](./fallow.md#status-snapshot-as-of-2026-05-01) for the full ship summary.

 The scan's "PASS" list (dead-code / dupes / complexity / boundaries / fix actions, runtime/V8 coverage merging, framework plugins, PageRank summarization, skyline visualization, daemon process, embedded intent classification) has been folded into [roadmap.md § Non-goals](../roadmap.md#non-goals-v1) — that's the canonical home; do not duplicate here.
