The dlx cache path is <cacheDir>/dlx/<key>/<prepare>/node_modules/.pnpm/ <pkgId>/node_modules/<pkg>. The <key> (64-char sha256 hex) and <prepare> (<time>-<pid> in hex) segments are dlx overhead on top of pnpm's already- deep virtual-store layout. For a transitive dep with a long name this tips the package directory over Windows' MAX_PATH (260) — measured at 259 chars for @pnpm.e2e/pre-and-postinstall-scripts-example in the dlx e2e test. A lifecycle script then runs with that directory as its cwd, and CreateProcess fails to resolve an over-length cwd, which Node surfaces as the confusing "spawn C:\Windows\system32\cmd.exe ENOENT". Flaky rather than constant because the <prepare> and temp-dir segments vary in length, straddling 260. Shorten both dlx-specific segments: - cache key: createShortHash (32 hex, 128 bits) instead of createHexHash (64). pacquet already truncated to 32, so this also restores parity. - prepare dir: encode time and pid in base36 instead of hex.
