Research direction
Reproduce the panic from the code linked in commit f949012b404c97435d73c6bbae2cdd69f371ceec with rustc 1.81.0, then inspect compiler/rustc_middle/src/query/on_disk_cache.rs:520 and the incremental-compilation query stack. Done means reducing the trigger and preventing this internal compiler error for the supplied case.
