Send small cyan and blue pieces through the right cyan gate, then move the exposed pink piece through the left pink gate.
Clear green solids through matching gates while keeping the framed pink-and-green bend out of center.
At counter 2, exit the cyan vertical through the right cyan gate to make both counters 1; then exit the pink horizontal left to zero the cover while the shutter stays 1.
In the middle reveal, remove the red horizontal and purple vertical, then work the yellow block, cyan bars, long framed yellow bar and framed pink bend.
Raise the light-cyan vertical along the opened right side and align it with the right cyan gate while the lower shutter reads 1.
Exit that light-cyan vertical through the right cyan gate to make the shutter 1-to-0 and reveal long yellow bars plus cyan, pink and green bends.
Clear the lower purple blocks and red verticals, then remove the blue/cyan stair group to open turning room around the framed pieces.
Unwind the framed yellow bars and cyan, pink and green bends one at a time, restoring the center lane after each group.
Route the late pink/red vertical group, then send the remaining green pieces through the bottom green gate.
Drop the final red vertical and red corner through the bottom red gate for the empty-board PERFECT clear.

Board notes 5 details

Layout: Cyan, blue, pink and green pieces fill the upper chamber above an orange 9-cover and a blue 4-shutter, with two purple mechanism panels on the right.
Goal: Clear the upper wave, use the left-gate pink horizontal to finish the cover and the right-gate light-cyan vertical to finish the shutter.
Opening: Remove compact cyan and blue pieces to the right, then clear pink and green solids while delaying the framed bend.
Danger Zone: Long framed yellow/cyan pieces can occupy the shutter row and block the light-cyan vertical that must rise to the right cyan gate.
Mechanics: At the last ticks, a cyan vertical makes both counters 2-to-1, a pink horizontal makes the cover 1-to-0, and a later light-cyan vertical makes the shutter 1-to-0.
