Eleven `tests/*.rs` were eleven binaries, each linking the whole graph -- `wgpu` and all -- to run a handful of cases. They are modules of one target now, under `tests/cases/`, and `cargo test --test suite layout::` still picks one out. The fuzzers and the `*_cost` measurements stay their own targets: they are run on their own and want to be selectable without building the rest. `profile.test` takes `debug = "line-tables-only"`, which is what a backtrace here actually reads; the type and variable information was the bulk of what the linker was writing. Measured on this machine, rebuilding `iris`'s test targets after a change to the crate: 14.3 s before, 9.8 s with one target, 7.7 s with both. `target/` went from 45 GB to 13 GB. The suite still passes 102 tests, and the binary still carries `.debug_line`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
