Constant COMPOSITE_PARAMS 

pub const COMPOSITE_PARAMS: &[ParamSpec];

MilkDrop’s composite roster, in the order COMPOSITE_PARAMS declares it — the six flags and one multiplier its format carries, reachable from a preset and written by a converted bundle’s per-frame program.

They are here rather than warned about because the corpus says so. Counted over all 10 347 files, 2026-08-16:

bTexWrap=1       6 014   58 %
bDarken=1        3 686   36 %
bBrighten=1      1 445   14 %
bDarkenCenter=1    711    7 %
bInvert=1          576    6 %
bSolarize=1        445    4 %

Each is one select in a shader, and between them they reach most of the library.

The video echo joined them in Plan 0109 Phase 3, and it is the one member that is not a remap: echo_alpha/echo_zoom/echo_orient blend a second sampled copy of the finished field over the first. Only 252 files (2.4 %) set a non-zero echo alpha, which is why it waited — but where it appears it is load-bearing rather than decorative, and Songflower (Moss Posy)’s woven lattice is only one family of bars without it.
