#   * R (Rscript)      -> the Drive-Box drivers + tests  (src/endocrine/*.R)
#   * GNU Octave       -> the ETR torus + tests          (src/endocrine/etr/*.m)
#
# Synchronous + idempotent (safe to re-run; installs only what's missing).

# package (the CI uses the setup-alire action) and its CI is scheduled-only. Add
# it if you want web sessions to build/test the Ada side.
