"""Classify MOMO daily-sales source arrival from a read-only preflight log.
This parser never connects to MOMO, never imports files, never moves Drive
artifacts, and never authorizes DB / host / Drive writes. It turns the existing
`momo-drive-token-source-recovery-preflight.sh` evidence into a compact gate so
operators can tell whether they should keep waiting for a legitimate source or
start a separate safe-import preflight.
