cron-build-tifs.sh: only alarm on disk-guard abort (rc=2), not expected 404s

ecbba0fb99a582d72927ae468df73543651ca283 · 2026-06-02 09:05:24 -0700 · Steve Abrams

The ~408 designs with no source PNG fail every run (rc=1), which made the
wrapper log a misleading 'exited non-zero' nightly. Now rc=2 (disk abort) is
the only real warning; rc=1 logs as expected.
