#!/usr/bin/env bash
# run-host-report.sh — global reporting generation for all stacks
# (GOA/hacktivism, FP stage, FP prod, …).
#
# Shared behaviour (always):
#   1) update-suite → latest git.hacktivism.ch (local ~/.config never overwritten)
#   2) line-buffered run log (written continuously)
#   3) RUN_TIMEOUT wall clock for taler-monitoring.sh (default 600s)
#   4) always write HTML (first run / empty staging too) + Forgejo commit link
#   5) rsync to DEPLOY_WWW_ROOT (ERROR if not writable — v1.3.1)
#   6) monpages post-check: public FQDN must serve monitoring HTML
#   7) exit code: STRICT_EXIT default 1 (v1.7.1) — unit fails if publish/public pages fail
#
# Configure via env file (not in git):
#   ${XDG_CONFIG_HOME:-$HOME/.config}/taler-monitoring/env
# or TALER_MONITORING_ENV=/path/to/env
#
# Thin wrappers only set stack defaults then exec this script:
#   run-hacktivism-monitoring.sh
#   run-fp-stage-monitoring.sh
#   run-fp-prod-monitoring.sh
