Research direction

Start with the linked crater logs and the failure at tests/test_orderbook.rs:645 in the affected orderbook test. Reproduce the float assertion mismatch and investigate which Rust change causes the left and right values to differ. Done means identifying the regression and establishing a regression test or other verified resolution for the reported behavior.
