#
# HTTPS proxy + iframe URL probes. Sourced from bats files. Pairs with
# lib/rpc.bash but tests the URL surface a real user actually clicks
# (dashboard, /app/<id>/ proxy paths, direct-port iframes), not just the
# JSON-RPC API.
#
# Pattern: every probe is a skip-or-assert pair:
#   - if the container that backs the URL is not running → skip
#     (cleanly reports the dependency, doesn't false-fail)
#   - if it IS running → the URL MUST return 200
# That catches the "container up but UI broken" failure mode that the
# RPC-only tests miss (.198 today: archy-bitcoin-ui Up 12 minutes,
# but is the iframe actually serving usable HTML? this layer answers).

# Curl options for a probe: short timeout, follow redirects, ignore self-
# signed cert (the alpha fleet uses one), no proxy environment leak.
