* fix(groundroute): contain malformed web search and fetch payloads web_search and web_fetch assumed the GroundRoute 200 body was an object with a `results` list of objects, and read it outside the request try/except. A body that arrived as a bare list, as an object with a non-list `results`, or with non-object entries raised AttributeError / KeyError out of the tool boundary, so the tool call failed with a stack trace instead of the provider's format error. Validate the payload before normalizing it, following the containment rule already applied to brave (#6550), serper, serply, sofya, tencent_wsa and unbrowse: a non-object payload, a non-list `results` container, or a non-empty list holding no objects returns the structured format error, non-object entries in an otherwise valid list are skipped in order, and missing, null or empty results keep returning "No results found". * fix(groundroute): coerce non-string fetch fields web_fetch sliced the fetched page's `content` (falling back to `snippet`) to the snippet limit without checking its type, so a 200 body whose result object held a number, boolean, or object there raised TypeError / KeyError out of the tool boundary -- the same escape the previous commit closed for the container shape. A null title also rendered as "# None". Coerce non-string content to text before truncating, and render a missing or non-string title as empty, matching the coercion sofya and unbrowse already apply to their fetch fields. * docs(groundroute): scope the falsy-title note to actual behavior The guidance said a non-string title renders as empty, but the code only empties falsy titles; a truthy non-string title still renders as its text form via the f-string. Say "falsy" instead.
