Four fixtures linked the installed dependencies into a throwaway root with a single directory symlink at <fixture>/node_modules, then ran pnpm inside that root. pnpm does not recognise the modules directory it finds there and purges it; with CI=true it does so without a prompt. The purge followed the symlink and deleted the repository's own node_modules mid-run, so a test suite uninstalled the workspace it was running in. That is what produced the cascading, file-unrelated failures a full test:unit run reported, and it happened twice while running the suites for the adapter re-review. scripts/lib/fixture-node-modules.ts replaces all four sites: node_modules is a real directory whose entries are individual symlinks, so a recursive delete unlinks the fixture's own links instead of walking through one link into the shared tree. Resolution is unchanged. tests/unit/fixture-node-modules.test.ts performs the exact recursive delete pnpm performs and asserts the source tree survives, and check:adapter-inventory now fails on any reintroduction of the directory-symlink form — verified by putting the old line back and watching the gate reject it. A full tests/unit + tests/integration run now leaves the dependencies intact. removal-fixture, supply-chain and security-followup-archive, the three suites that had to be excluded before, pass in that run.
