Custom DIY Speaker PCB Design

"Make the buck converter loop (L1, C1, C2, D2) more compact and closer to U4"
I’ll tighten the U4 buck power loop by moving L1, C1, C2, and D2 closer to U4, then check the placement result for obvious layout issues.
I found U4, C1, and C2 in the current layout, but L1 and D2 are not present in the placed component list. I’ll compact the available buck-loop parts around U4 and ask the placement engine to include L1/D2 if they exist elsewhere in the project.
Processing was stopped.
Here's a summary of what I was working on: Evaluating layout and tools
I see that only C1, C2, and U4 exist, but it seems L1 and D2 might be absent from the layout. I need to figure out how to use the placement tool, especially since D2 isn't in the layout as expected. The user is asking about this, and I’m wondering if we can still call existing targets despite possible missing components. Maybe I should inspect the request to determine if a schematic is needed.
