    **What the agent learns:** The `B-*` wildcard matches all grid intersections along grid line B. Results span both disciplines. The agent groups by sheet to compare architectural vs structural columns at each intersection.

> The architectural plans show all columns at 16x16 (likely accounting for finish), but the structural sizes vary. B-3 has a larger structural member (W12x65 vs W10x49) which may explain why the architectural size is the same -- the 16" finish enclosure may not accommodate the larger steel at B-3. This is worth verifying with the structural engineer.

| Key technique | The `B-*` wildcard matches all intersections along grid line B. Features from different sheets are returned together, and the agent uses `sheet_number` to group by discipline. Cross-referencing column sizes is pure agent reasoning. |
