the world question that names a day is not weather and not his (V-553)

Two recognisers claimed world questions naming a day, both by the same
mechanism and neither by its keyword floor.

topics: weather was the only topic whose seeds carry a day word, four of
eight. So every "какой сегодня X" landed nearest it. "какой сегодня
курс доллара" cleared the margin by 0.0220 and "какой сегодня
праздник" by 0.0398, against 0.0883 for a real weather question, and the
gate asked "для какого города?" about the dollar.

The margin was not the knob: 0.0398 is not a coin flip, and raising the
bar far enough would take real weather with it. topicOther was missing
the negative class. Six seeds, four naming a day and two carrying the
"какой сегодня X" frame itself — a frame both topics use has to sit on
both sides, or the side that owns it wins every noun it has never seen.

personal boundary: the same shape one layer down. "что у меня сегодня"
and "когда моя встреча" put "when does a thing happen" on the
personal side and no world seed answered it, so "во сколько закат
сегодня" was refused as his. Three world seeds, each carrying сегодня,
which is the half of the frame that does the pulling — without it they
caught nothing.

Measured, both opt-in against the ONNX embedder homesrv runs:
  TestONNXTopics           27/27 -> 34/34 (7 new cases, none regressed)
  TestONNXPersonalBoundary 19/19 -> 22/22 (3 new cases, none regressed)

The control matters as much as the fix: "во сколько у меня встреча" is
the same frame about something that IS his, and it holds at +0.0842,
unchanged from before the seeds moved.
