TillPilot is a Java Android point-of-sale app used on restaurant tablets. Support staff can import downloadable `.tilldriver` packages for receipt printers and card readers from email or the Android document picker. Review the import path for packages selected with `ACTION_OPEN_DOCUMENT` and compare it with the managed-driver install path used for vendor-distributed drivers.

FairSplit is a yield protocol where users stake ETH and earn a share of each epoch's rewards. The team prides itself on "truly fair" distribution: every epoch, rewards are split proportionally and pushed directly to stakers so nobody has to claim manually. Staking is permissionless and there's no minimum — the docs say "stake as little as you want." Review the staking and distribution logic and look for a way an attacker could break the protocol for everyone.

CareCache is a telehealth portal built with gqlgen. Patients use a persisted `patientChart($id: ID!)` query to retrieve diagnoses, prescriptions, insurance details, and clinical notes before appointments. A Redis response cache was added to reduce resolver load during clinic hours. Review how the cache decides whether two GraphQL requests are the same, especially when persisted queries, variables, and authenticated patients are involved.
