# The e2e suite runs 400-700s against go's 600s per-package default, so a

# an unrelated failure. A real hang still fails, just later.

# Also refuse a dirty tree. Every build target compiles the working tree, not
# HEAD, so uncommitted work ships silently -- and migrations/ is embedded, so a
# migration file that exists only on disk still migrates the production
# database on restart. That happened once: 0027 reached gitbay.org inside an
# unrelated deploy, an hour before it merged. Untracked counts; go:embed does
