Yajilin (exercise)

During WPC 2023, Craig and bakpao hosted a speed-setting contest in person. The prompt was to make a Yajilin variation. Here's the Yajilin (exercise) I came up with, which won 1st place! It's only slightly cursed. Penpa link: https://tinyurl.com/ytfydo2d

Rules: Shade some cells in the grid so that each arrow (yajilin clue) sees the indicated number of shaded cells. Some shaded cells are given. Shaded cells may be adjacent. Then treat the resulting grid as an Exercise puzzle. That is, draw a directed loop through cells which can push shaded cells into empty cells. A shaded cell can move exactly once in the direction it's pushed, and can only move once. Shaded cells can't push other shaded cells. The finished, traversed loop must pass through all empty cells in the grid.

Note: The yajilin clues only care about the shaded cells before they've been pushed by the loop.

I've been told the rules are confusing (what a surprise!), so here's an example:

Below is the solution. The loop goes clockwise.

Here is a visual of where the shaded cells end up after being pushed. Note that the new locations of the shaded cells don't need to satisfy the yajilin clues.
