<@778624824875941908> <@756504518417711104> HUGE bug in the copper pour solver. It accepts a connectivity map key that is NOT the subcircuit connectivity map key????? Massive footgun, please fix!!!! I tried to recommend this library to someone on X and I couldn't believe how bad that was!!!!

## Seve — 2026-06-24T05:04:34.808000+00:00

I actually spent a while on this because i couldn't believe this API design decision

## Seve — 2026-06-24T05:04:56.218000+00:00

I generated a usage section for the README and it was askin gthe user to generate a connectivity map prior to passing in the circuit json!

## Seve — 2026-06-24T05:06:13.288000+00:00

this is totally wrong! It doesn't make any sense! Generating a connectivity map is not guaranteed to be deterministic and is not a requirement of getting a copper pour!!!!

## Seve — 2026-06-24T05:06:53.030000+00:00

Just accept `subcircuit_connectivity_key` or whatever the appropriate key is- this is a massive footgun as is!!!!

## Seve — 2026-06-24T05:08:33.382000+00:00

i will also say-  POOR README AND NO COSMOS ON THAT PROJECT!!!!

This is below our standards!!!!

<@757706909351411845> the snapshot change is a fix

## shibo — 2026-06-24T15:25:05.077000+00:00

Those vias are connected to gnd as far as I knwo

## Seve — 2026-06-24T15:54:59.472000+00:00

they look like unassigned vias

## Seve — 2026-06-24T15:55:04.812000+00:00

i would double check

## Seve — 2026-06-24T15:55:15.656000+00:00

that board is a viagrid/assignable via style board iirc
