# hns_watchdog.py — PGŽ Sport HNS pipeline watchdog (SUB7)
# Author : Damir Radulić  <dradulic@outlook.com> / <damir@rinet.one>
# Date   : 2026-05-05
# Version: 1.0.0
# Purpose: Periodically poll DB progress for the HNS scraping pipeline,
#          detect stalls, restart fallen worker processes and send Telegram
#          status updates every 30 minutes. Fires a special "ALL DONE" alert
#          once the mission goal is reached.
#
# Modes  : --once    run a single check and exit (cron-friendly)
#          --daemon  loop forever, sleeping CHECK_INTERVAL_SEC between checks
#
# Goal   : 59/59 PGŽ financirani klubovi sa hns_klub_id, ≥80% igrača s
#          profile_complete=true (visina_cm IS NOT NULL), ≥1000 utakmica.
