COB-exact: timeline 1:1 from armmh.cob (activatescr/deactivatescr, disassembled with _cob_dis.py). StateChg staged-deploy family: 4 open stages, then the compiled close order — not a reversed activate. Fire/hit/death/smoke scripts are engine-driven or firing-only and not part of this loop.

- 0.00–0.40 s — Closed rest pose (3DO zero point)
- 0.40–0.75 s — activatescr stage 1: base x-turn 0.0°→1.1°, box x-turn 0.0°→-20.4°
- 0.75–1.11 s — activatescr stage 2: base x-turn 1.1°→0.0°, box x-turn -20.4°→-70.3°
- 1.11–1.46 s — activatescr stage 3: base x-turn 0.0°→-3.2°, box x-turn -70.3°→-93.2°
- 1.46–1.83 s — activatescr stage 4: base x-turn -3.2°→0.0°, box x-turn -93.2°→-90.0°
- 3.03–3.29 s — deactivatescr stage 1: base x-turn 0.0°→-3.2°, box x-turn -90.0°→-93.2°
- 3.29–3.56 s — deactivatescr stage 2: base x-turn -3.2°→0.0°, box x-turn -93.2°→-70.3°
- 3.56–3.82 s — deactivatescr stage 3: base x-turn 0.0°→1.1°, box x-turn -70.3°→-20.4°
- 3.82–4.10 s — deactivatescr stage 4: base x-turn 1.1°→0.0°, box x-turn -20.4°→0.0°
- 4.10–4.70 s — closed again — loop restarts (fire/hit/death scripts are engine-driven, not in this loop)
Every stage duration equals its COB sleep exactly; values are raw COB units (turns: BAM 65536 = 360°, moves: elmo × 163840). Renderer conversions follow the proven family conventions (_cob_anim.py).
