MEDIUM

Why flagged The package installs a prebuilt binary 'kitch-setup' downloaded from 'broth.itch.ovh'. While this domain appears to be itch.io's own CDN/distribution infrastructure (broth = their update/distribution system, itch.ovh is a known itch.io-operated domain), it is not a standard well-known host like GitHub releases. The binary is executed directly and installed to /usr/bin/. The sha256sum is pinned, which mitigates MITM risk, but the supply-chain trust depends entirely on broth.itch.ovh being legitimately controlled by itch.io. Given that itch.io does operate broth.itch.ovh as their official butler/setup distribution endpoint, this is likely legitimate, but the pattern of a prebuilt binary from a non-primary domain warrants medium classification rather than clean.
