Owner directive 2026-07-15: extract pillars and make auto-placement avoid them.
- tools/cad/extract_pillar_seed.py: K1 pillars from CAD layer 4-COL-H
(cross-validated against official drawing dims 54/117m south wall pillars);
K2 H7-H10 from official drawing dimension annotations (one interior midline
pillar each, dia 2.3m); H6 not seeded (no source - recorded as limitation)
- V62: hall_pillar table + 74 seeds; also corrects V61 trench y-axis
(RT points were seeded in CAD-y without the top-of-drawing flip - now 63-y,
generator fixed as the canonical form)
- Engine: autoGenerate reserves pillar radius + 0.6m buffer, packing skips
overlapping cells; HallInfo.pillars contract extension (additive, NON_NULL)
- Canvas: structure layer renders pillar circles (editor passes hall pillars)
