Moon-Sized Alien Construct Violent Activation Sequence

the prompt

Ancient alien construct the size of a moon: activation sequence begins, not smooth but violent, unstable, and overwhelming nearby space.  Wide shot: dead structure flickers to life, sudden energy surge instead of gradual activation. Close surface tracking: plates begin shifting abruptly, grinding and snapping into new positions. Near-crush moment: a ship flying too close gets caught between moving segments, escaping at the last second. Internal glow: energy pulses misfire, surging unevenly through exposed structures. Scale break: entire sections detach suddenly, drifting, then snapping into new alignment mid-space. Whip pan: a beam of energy lashes out unpredictably, forcing nearby ships into evasive dives. Tight shot: intricate machinery unfolding too fast, parts colliding then correcting, barely stabilizing. Shockwave: a failed alignment releases a violent pulse, pushing everything outward. Desperate retreat: ships trying to escape as gravity distortions begin forming around the structure. Final reveal: the construct stabilizes abruptly, now fully active, movement suddenly precise and controlled after chaos.  Unstable activation, near-disasters, overwhelming scale, aggressive motion, alien but mechanically consistent.
