Owner directive 2026-07-16: verify the K1 band-hall numbering assumption.
Decisive evidence: 832 electrical circuit labels (P{panel}-{hall}{zone}-{no})
in the trench drawing, zero exceptions: band1=hall5(165) band2=hall4(168)
band3=hall3(168) band4=hall2(168) band5=hall1(163) => band n = hall (6-n).
The previous assumption (band n = hall n) was WRONG - only hall 3 matched by
luck. Mirror features in official JPGs (notch corners, exterior entrances)
independently agree.
- V67: delete all K1 measured rows (old mapping) and reseed with corrected
generators (trench 875, pillars, obstacles, K1 exits). Assembly strips the
V61 y-flip UPDATE (would double-flip) and the global obstacle DELETE
(would wipe K2 rows)
- Swap DWG-tab underlays hall1<->hall5, hall2<->hall4
- All 5 generators now canonically map band = 6 - hall
