- only `cache-seeder` writes caches, every other workflow restores. Saves were being rejected once the repo went over its cache budget, leaving main's caches stale and PR runs building cold - seed the pnpm store and uv caches next to the go ones, so PRs warm-start on them rather than installing from scratch - prune keeps a single generation per key, including across go versions, where a toolchain bump leaves the previous build cache unusable. Reclaims ~2.6 GB immediately - prune runs every 6h instead of daily and trims to 6 GB, since CodeQL writes ~200 MB per push to main from outside this repo's workflows - pull requests and release branches no longer write pnpm, uv and binfmt caches, whose ref-scoped copies are never read again --------- Signed-off-by: silverwind <me@silverwind.io>
