The 'Test Go code' job was dominated by a single package: 'plugins' took 541s of the 699s test step. The suite builds 25 test plugins as full-Go wasip1 modules of ~4.5MB each, and wazero must compile every one to machine code. Under -race that compiler work is instrumented, so each module costs around 11 seconds. The suite already shared a wazero compilation cache, but three things kept it from paying off. It lived in a fresh temp dir, so nothing survived the run. The default plugins.cachesize of 200MB was smaller than the 334MB the cache actually needs, so the purge evicted entries mid-run. And the wasm binaries embedded VCS stamps, so every commit produced different bytes and missed the content-addressed cache anyway. Point CacheFolder at plugins/testdata/.wazero-cache, raise the test cache limit past what the suite needs, build the test plugins with -buildvcs=false, and restore the directory in CI. Locally the package goes from 256s to 74s with the cache warm and the wasm rebuilt from scratch.
