Aha, thanks! Should be possible to output barycentrics into the g-buffer :) Might even flip it into a v-buffer based renderer at some point anyway!

It's a pretty common thing with ray tracing, see e.g. https://wiki.povray.org/content/Knowledgebase:The_Shadow_Line_Artifact
Increasing the shadow bias is going to cause leaks, but I believe there are recent solutions to this problem -- e.g. Blender just fixed this.

The fix from chapter 4 of Ray Tracing Gems II is pretty good but it requires barycentric coordinates for it so I'm not sure how you'd adapt it for this.
