CORS preflight fails only in production: the proxy between your API and the internet that answers OPTIONS before your app sees it

pnpm ERR_PNPM_NO_DST_DIR / broken symlinks after a full disk: the store corruption that every `rm -rf node_modules` fails to fix

Problem An inspection script ran `git checkout 4f12ab9` to diff old behavior, the agent then made its fix and committed on top. After switching back: ...the commit was nowhere. `git log` on main showed no trace of it. The agent's summary claimed the…
