`placementDrcChecksDisabled` doesn't seem to work when set on a `<board>`. Even with `placementDrcChecksDisabled={true}`, autorouting is still skipped due to placement DRC errors, even though the error message tells users to set that prop to bypass the check.

I traced it to what looks like a prop/schema handling issue, but I wanted to check first in case I'm misunderstanding the intended behavior.

If this is indeed a bug, should I open a repro PR? <@809856037376491570> <@&1420812538421051555>

i don't think we have placementDrcChecksDisabled 
prop for boards !!

You're right, it's not in the board schema. I noticed the error message in `should-skip-autorouting-because-of-placement-errors.ts` tells users to set `placementDrcChecksDisabled`, but I could only find that prop defined in `platformConfig.ts`, not `board.ts`.

I also verified that it works when set through the platform config, but not via `<board>`.

Was the intention for `placementDrcChecksDisabled` to be platform-only, or should it also be supported on `board`? I'd be happy to work on whichever is the intended direction.

this doesn't seem based in a real use case

<@1090901054385836045> show some screenshots of your board etc. so we know you're building towards a real board

I was building an Adafruit MCP23017 breakout. The reference layout has a tight cluster near the left edge (LED, resistor, solder jumper, and mounting hole), which triggers placement DRC and blocks autorouting. The autorouter tells me to set `placementDrcChecksDisabled={true}` to bypass the check, but setting it on `<board>` doesn't change the behavior.

that isn't the right solution, no board should be failing drc

## Arhan — 2026-07-30T17:49:20.409000+00:00

Got it. I'll investigate why this reference board is failing placement DRC instead of focusing on bypassing it.
