C3D-0013 · Move manhole notes to SEWER_MANHOLE_TEXT [MH-MOVE] done

Moves the 14 MH/RIM/IN/OUT notes and their leaders from SEWER_LINE_TEXT to SEWER_MANHOLE_TEXT. Identified by content so nothing else on the source layer is touched.

C# payload

// The manhole invert notes went on SEWER_LINE_TEXT; they belong on SEWER_MANHOLE_TEXT.
// HCWA: text describing a manhole goes on the manhole's own _TEXT layer, not the line's.
// Moves the 14 MText notes and their leaders. Identifies them by content (RIM/IN/OUT) so
// nothing else that may already live on SEWER_LINE_TEXT is disturbed, and moves any leader
// whose endpoint lands on one of those notes.
// Host owns Tx; host regens after commit.

Result

moved 14 note(s) to 'SEWER_MANHOLE_TEXT'
moved 13 leader(s) to 'SEWER_MANHOLE_TEXT'
'SEWER_LINE_TEXT' now holds 0 entit(ies); 'SEWER_MANHOLE_TEXT' holds 27 (verified)
