"""Tests for the TP1X_DA-AC-CAC-01001_0000 cassette AC (issue #191).

0.16.0's device-type simplification dropped oneUiVersion detection on the
assumption every device it typed was already reachable via a modelNum board
token -- this board was the one exception (its oneUiVersion self-reports
"7.0 Air conditioner", but 'CAC' had never been added to the board-token
table), so it silently fell back to common caps and lost its climate entity.

This dump is NOT fully covered yet -- eight hrefs remain unbound (edge
lighting, a second stateful light resource, absence-clean, four
`/settings/sound/*` resources, smart-sensing-cooling), all genuinely new to
this board generation. That's a real device-support gap, left documented
here rather than guessed at, per the 'don't guess' rule -- fixing the
routing regression was the scope of #191.

/uvled/vs/0 and /filter/airdustPM1filter/vs/0 used to be on this list too,
until issue #270 (TP1X_FAC_TIME_23K) added real capabilities for both --
this board's own live filterUsage/filterStatus data on the PM1 filter binds
through the same exists_fn-gated entities #270's dump (which has neither
field) leaves empty.
