Implemented native side-thread construction (hole 1.176, bolt 0.85), circle-centerline group modes, current native LineFormat inheritance, canonical coordinates, transactions, and Web selection normalization/clearing. Thread group reuses its existing four-way dispatch and bottom-view handlers.
Build, artifact synchronization, and business acceptance remain with the outer pipeline. No runtime acceptance is claimed. Validate both centerline modes, all four thread modes, scaled/rotated views, reversed endpoints, invalid references, active-task exclusion, undo/redo, save/reopen, and rendered cosmetic edges. The new native paths request paint; browser SVG refresh and durable document behavior still require runtime verification. Existing bottom-thread handlers retain their explicit style/width/color/visible contract.
