COB-exact: timeline 1:1 from ARMAAP.COB (rev31.gp3, the 3.1 balance). the ARM Advanced Aircraft Plant — a full factory show: three-stage hall open, production pad spinning at 30°/s, radar dish at 150°/s, and the compiled close order.

- 0.00–0.40 s — Closed — the radar dish spins at 150°/s from the first second on (Create) and never stops
- 0.40–0.91 s — Stage 1: the two building halves slide apart 7.8 elmo (13.7 elmo/s)
- 0.91–1.43 s — Stage 2: the nano boxes slide out 7.7 elmo
- 1.43–1.95 s — Stage 3: the nano emitters extend 3.55/4 elmo
- 1.95–4.95 s — Production — StartBuilding spins the build pad at 30°/s (StopBuilding stops it)
- 4.95–5.47 s — Close, the compiled order: emitters retract (514 ms)
- 5.47–5.98 s — nano boxes in (518 ms)
- 5.98–6.50 s — building halves close (519 ms), sleep 26
The close is replayed in the compiled order with its own move-now snaps — the script re-poses the open pieces instantly before folding them back, exactly as the bytecode does.
