Research direction
Reproduce the swap URL and state shown in the report, then trace the source implementation behind createUncheckedTrade, encodeSwaps, and swapCallParameters. Identify which invariant fails for this token and verify that the same swap no longer crashes, with a regression test if the relevant test entry point is found.
