An unknown control method returned a flat "unknown method: <x>" with no hint — so `POST /connect` (a plausible guess for the visual-edge method, which is actually `connect_nodes`) was a dead end. Silent-ish for an LLM/human driver: you can't tell a typo from a missing feature. Dispatch now appends "did you mean: a, b, c?" — ranking handler keys by prefix match, then substring, then Levenshtein distance (dropping far matches), with ties broken by shorter name so the closest candidate leads. `/connect` -> connect_nodes, connect_mapping, connect_control_to_param; `/get_map` -> get_mappings, ...; a nonsense method still gets no suggestions. General (helps every future typo). No new method / behavior change beyond error text -> MCP parity unaffected. Full ctest 99/99.
