…over 13 stores Replace lru_cap / lru_cap_bun / lru_cap_mise_installs with a single lru_entries engine driven by STORE_TABLE (bun npm pnpm gradle cargo rustup konan mise-data mise-cache hk pub toolcache + the action archive cache). Whole directories are evicted where partial entries are unusable (bun packages, gradle versions, toolchains, tool versions), files elsewhere, with global LRU across a slot's stores and a budget of min(CACHE_BUDGET_BYTES, CACHE_BUDGET_PCT% of the fs) per slot. Slots under $RUNNER_DATA_DIR/slots are pruned under .prune.lock and skipped while a fresh busy marker exists. The loop checks df every PRUNE_CHECK_SECONDS and prunes fully when free space is low or the interval elapsed, with a tighter docker prune under pressure.

pnpm's store lives in cache/pnpm/store and its metadata cache in cache/pnpm/cache (both symlink targets). Evict them together, emptying the directory but keeping store/ and cache/ so the container symlinks stay valid. Also test that control slots without a cache/ dir are skipped.

RUNNER_DATA_DIRmounted at the same path into the pruner service and passed as env, with slots at$RUNNER_DATA_DIR/slots/<id>/{cache/<store>,busy,.prune.lock}. Without it the pruner finds no slots and only trims the action archive cache. Merge together with, or right after, W3's PR.docker-compose.yml, hooks, README and workflows are untouched here.Tests
