#
# The harness gauntlet: discovers and runs every tests/*/run-tests.sh, one
# summary line each, worst exit wins. This is the TOOLING gate -- run it after
# any script/harness change (the change-delivery loop) and before trusting the
# gate scripts in a deploy. Deliberately NOT folded into preflight.sh:
# preflight gates the DEPLOY TARGET, this gates the TOOLS -- different cadence,
# different failure meaning.
#
# [filter] runs only harnesses whose directory name contains the substring
# (e.g. `bash scripts/run-tests-all.sh phase-06`).
# Mutates NOTHING (harnesses confine themselves to mktemp dirs).
# Exit: 0 all green | 1 any harness failed | 2 no harnesses matched.
# ASCII + LF.
