The rapier crate also published a blog post highlighting a major change to its underlying math engine, in its 0.32.0 version so I asked Opus 4.5 to upgrade to that version…and it caused crashes, yet tracing the errors showed it originated with rapier itself. Upgrading to 0.31.0 was fine with no issues: a consequence of only using agentic coding for this workflow is that I cannot construct a minimal reproducible test case to file as a regression bug report or be able to isolate it as a side effect of a new API not well-known by Opus 4.5.
