SelectorPath is full

Error message

SelectorPath is full

What it means

TinyVec::push exceeded its fixed PATH_LENGTH backing array. Selector paths in the stores subscription system have a hard-coded maximum depth; pushing more path keys than that capacity panics instead of growing, since the array is inline.
