# A stubbed `ctest` for scripts/ci/control_smoke_test.sh.
#
# Descended from the verification agent's stub (wave1-codex-verify.md 8, ~/w7/p5-verify-f8-stub/ctest),
# which is what CONFIRMED that the negative controls accepted an unrelated failure. Every mode below
# is deliberately the BEST case for the control under test: the selection is never empty except in
# the mode that exists to test the empty-selection guard, and the baseline is green except in the
# mode that exists to test the red-baseline guard. If a control passes here it is because the
# control's logic is wrong, not because the stub starved it.
#
# STUB_MODE:
#   unrelated          baseline green; the control's own run fails with UNRELATED_CONTROL_FAILURE
#   evidence           baseline green; the control's own run fails with the scenarios' own wording
#   green              baseline green; the control's own run PASSES (the knob is not load-bearing)
#   red-baseline       the baseline itself has a failed entry
#   all-skipped        the baseline is entirely skipped (the disarmed lane, a legitimate exit 0)
#   retrace-noselect   `ctest -N` matches nothing; the run exits 8 the way --no-tests=error does
#   retrace-unrelated  one match; the run fails without naming the transport
#   retrace-evidence   one match; the run fails with run_trace_case.cmake's own sentence
#   retrace-green      one match; the run PASSES
