`npx` unconditionally re-reifies `file:`/directory specs on every invocation, even when the package is already installed in the npx cache. This happens because `missingFromTree()` has an early return for directory specs that bypasses the cache lookup entirely. Registry packages correctly skip reify on cache hit by checking `node.package.resolved === manifest._resolved`, but directory specs never reach that check. The fix makes two changes to `missingFromTree()` in `libnpmexec/lib/index.js`: 1. The early return for directory specs is now scoped to non-npx trees (`!isNpxTree`), so the npx cache tree is actually consulted on subsequent runs. 2. Added `node.realpath === manifest._resolved` as an alternative match condition, since `file:` spec nodes in the npx cache have `undefined` for `package.resolved` but their `realpath` contains the matching absolute path. A regression test verifies that running `exec` twice with the same `file:` spec only triggers `reify` once (on the cold cache run). ## References Fixes #9251 (cherry picked from commit e9b0157)
