soic8 and qfn32 asserted only snapshots — a stable 14% courtyard drift passed silently. They now carry explicit ceiling assertions matching the measured drift (14.24% and 13.08%), so CI fails loudly if the drift grows. The bespoke 16 ceilings on soic20/soic24 gain comments recording the measurements and pointing at tscircuit#731. This is the visibility half of tscircuit#731; the geometry half (matching KiCad the way the other 84 footprints do) stays open pending maintainer direction on the legsoutside variants.

Addresses the visibility half of #731
What
Per the issue's measurements, the four worst parity footprints were exactly the ones not held to a real bound. This makes every exemption explicit:
soic8(measured 14.24% off) andqfn32(13.08%) previously asserted only snapshots — stably wrong passed silently. Both now carry explicittoBeLessThan(15)/toBeLessThan(14)ceiling assertions, so any growth in the drift fails CI loudly while the current state stays green.soic20/soic24keep their bespoke16ceilings but gain comments recording the measurements (~15.3%) and pointing at 4 footprints are 13–16% off KiCad courtyard parity, and all 4 are exempt from the threshold #731.The geometry half (aligning these four to KiCad like the other 84) is deliberately left open pending your direction on whether the
legsoutsidevariants are intentionally different.Verification
