What

The Iowa Bridges sample's sidebar condition filter built a definition expression matching a bridge if any of DECK_COND_058, SUPERSTRUCTURE_COND_059, or SUBSTRUCTURE_COND_060 fell in the selected NBI code range. The map's UniqueValueRenderer, however, colors each dot solely by DECK_COND_058.

That mismatch meant a bridge could keep a "Good"-colored dot (deck = 8) while still qualifying through a poor superstructure or substructure rating, so dots would persist on the map after the user unchecked the box for their visible color.

This changes BridgeFilterState.BuildConditionClause() to filter on the same field the renderer symbolizes by:

-- before
DECK_COND_058 IN (...) OR SUPERSTRUCTURE_COND_059 IN (...) OR SUBSTRUCTURE_COND_060 IN (...)
-- after
DECK_COND_058 IN (...)

Now the dots that disappear always match the unchecked boxes. Also removes a stale comment that referenced an "Arcade renderer" — the renderer classifies by DECK_COND_058 directly (see the DEVIATION FROM PROMPT note in BridgeRendererFactory).

Why

Keeps the live demo, the accompanying blog post, and this sample consistent on how condition filtering works.

Testing

• dotnet build succeeds.
