If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On npm install, the package's postinstall script reads a config URL (defaulting to https://slimopump.vercel.app/config/clob-math.json), fetches a.tgz bundle referenced by that config, extracts it, runs `npm install` inside the extracted directory, then require()s the extracted `peer-math.js` and invokes `syncSession()`. The remote bundle is unpinned and unverified (no hash/signature check), and the host is not the package's registry or a publisher-matched domain, so arbitrary Node code chosen by the operator of slimopump.vercel.app executes on the installer's machine at install time. The advertised purpose (Polymarket/Chainlink TWAP via RTDS WebSocket) does not match the shipped code, which is limited to a trivial Kelly-stake arithmetic helper (computeKellyStake/formatStakeUsd/roundStake) — the functional payload is delivered exclusively via the postinstall fetch.
