Why flagged
The package downloads source code from the project's own GitHub and the official CERN host for ROOT; both are project-owned and expected for building, despite the non-whitelisted ROOT download host.
Triggered rules
Low
AI review downgraded a static finding
llm_review
The static rules flagged this MEDIUM, but an AI model (qwen/qwen3-235b-a22b-07-25) reviewed the full PKGBUILD and judged it LOW (confidence 95%): The package downloads source code from the project's own GitHub and the official CERN host for ROOT; both are project-owned and expected for building, despite the non-whitelisted ROOT download host.
1 higher static finding superseded - not the current verdict (shown for transparency)
Medium
source=() URL on a non-standard host
source_untrusted_domain
One or more source=() URLs point to a host outside the trusted allowlist (github.com, gitlab.com, codeberg.org, pypi.org, …).

# cppyy-cling and ROOT have a weird relationship: Cling is developed as part of ROOT without
33
# separate releases, so it is basically forked and patched in the cppyy-backend project.
34
# It also builds and installs some binaries provided by ROOT (rootcling, genreflex).
35
# On the other hand, ROOT has PyROOT which uses cppyy, so it forks it back to build it
36
# against the ROOT-provided Cling. There are also some licensing reasons...
