# Exits 0 when a resignation letter would actually be delivered.
# Exits 1 when something would silently drop it, and prints the fix.
#
# Why this exists: on 2026-10-09 a resignation letter for SUNE PIETERS was
# reported as "sent successfully" while himalaya was missing from PATH and
# the PDF service was down. Nothing failed loudly. This script makes it loud.
