While building a board in the `tscircuit` repo, I noticed something and wanted to check if it's intentional. I was trying to disable placement DRC so the autorouter could continue despite overlapping footprints. `Circuit({ platform: { placementDrcChecksDisabled: true } })` works as expected, but `<board placementDrcChecksDisabled />` has no effect—the placement errors remain and autorouting is still skipped. I traced it and found the board prop gets stripped by the component schema before it reaches `@tscircuit/core`. Is `placementDrcChecksDisabled` only intended to be supported via `PlatformConfig`, or is this an oversight?

it is an oversight probably
Arhan
In that case, would you prefer I open an issue in `@tscircuit/props` ?
Seve
no sorry i thought you said it was part of the board spec
Seve
i don't know what the api is for adjusting the DRC checks via board
Seve
i would need more evidence to make the determination

I dug through the history, docs, PRs, and type definitions. I couldn't find evidence that `placementDrcChecksDisabled` was ever intended to be a board/group prop. The docs only expose it through `PlatformConfig`, and all of the PRs that introduced the DRC flags scoped them to `PlatformConfig` only. The reason I thought it might be an oversight is that `schematicDisabled` followed a similar evolution and was later mirrored to board props, and core already supports inherited properties. But I don't have enough evidence to conclude that was the intended API here.

thanks for doing the research!
