The Tools screen mounts the Results panel only once a call has produced a
result, but the panel's zero-content branch rendered "No results yet" — the
same wording it would use before anything had run. An empty `content` array
with no `structuredContent` is a legal `CallToolResult`, so a call that had
plainly completed reported itself as a call that never happened.
That reads worst after a multi-round-trip (MRTR) sequence, which is how it was
reported: the user answers one or more embedded elicitations, watches the
Protocol tab group the exchange and mark it COMPLETE, and is then told there
are no results yet. Nothing was lost — the result was stored and rendered; the
panel simply had no wording for "completed, returned nothing".
The panel now renders an "Empty result" alert saying the call completed and
returned no content. This is the remaining half of the same gap #1908 closed
for `structuredContent`-only results.
test-servers: new `mrtr_empty` preset (`createMrtrEmptyResultTool`) — one
elicitation round, then a complete result with `content: []` and no
`structuredContent` — added to `mrtr-showcase-http.json` so the shape is
reproducible by hand. README documents it.
