Two defects in the deck, both of which reach him as a broken answer.
An optional placeholder had no rule. net_empty carries {tail} for the case
where a scan stopped short of the whole range, and a scan that finished has
nothing to put there — so the answer went out with the braces in it, or with
nothing at all if the variant was all placeholder. The picker now narrows to
the variants this call can actually fill, and prefers, among those, the ones
using the most of what the caller supplied, so a caveat he was given is never
dropped for a shorter wording. Nothing fillable still says the line, because a
visible placeholder beats silence.
The floor literals lived in one global map keyed by bare entry name, and two
families both define an entry called query_unknown: the query answers, where
she looked and found nothing, and the phrasing fallbacks, where she failed to
say an answer she had. Whichever registered last answered for both, so the
distinction those two files exist for disappeared exactly when a file failed to
load. Each family now carries its own map, and an unloadable file leaves a
floor-only deck behind instead of a nil one.
