🐛 What
The installer/preflight specs create scratch directories with Directory.CreateTempSubdirectory("gw-…") and never delete them. On a dev box with a tmpfs /tmp (1,048,576-inode budget) a week of test runs left 59,973 gw-setup-story34* / gw-preflight-story342-* dirs (each a fixture checkout of 58 files) — about 500k inodes. Combined with one scratch copy of the repo, /tmp hit 100% inodes and every tool on the box failed with ENOSPC: no space left on device.
Census after cleanup (still leaking, smaller): gw-preflight-bin-* ×1840, genwave-pawire-* ×917, story343-env-* ×916, gw-preflight-env-* ×462, gh332-{bin,env,log}-* ×153 each.

gw-setup-story344-*, gw-setup-story345-*, story343-env-*), the gh332 spec, and whichever spec uses the genwave-pawire- prefix — same pattern.
✅ Fix shape
One TempDir : IDisposable helper in the Host test project (create in ctor, Directory.Delete(path, recursive: true) in Dispose, swallow IOException), used via using var at every call site. Optionally an xUnit collection fixture that sweeps Path.GetTempPath()/gw-* older than an hour at startup so stale runs self-heal.
🧪 Acceptance
ls /tmp | grep -c '^gw-' is unchanged before/after dotnet test --filter FullyQualifiedName~Story346.
