# Decisive probe: can the EMULATOR actually reach the host mock via 127.0.0.1?
# If any in-emulator method prints the health JSON, the network path is good
# and any flow failure is app-side; if none succeed, attribution falls back to
# a host-side check + adb reverse state so we at least know the mock is up.
# `toybox wget`/`nc` don't work reliably on the API-28 image (wget: unknown
# command; nc connects but the request/response framing is unreliable) — so
# this tries curl (if present), then mksh's /dev/tcp pseudo-device (a shell
# builtin, not an external binary, so it survives whatever toybox applets
# this image did/didn't build), then nc as a last in-emulator attempt, before
# falling back to a host-side confirmation. This never blocks the flow — the
# result is recorded and the script continues regardless.
