# 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
#   missing-fatal      private file exists but lacks Fatal (stdout status still fails)
#   stdout-fatal       Fatal exists only on stdout, never in the private file
#   stale-fatal        Fatal exists before reset, never from this control run
#   e3-unrelated       E1 has its private Fatal; E3(a) fails for an unrelated reason
#   e3-no-private      E1 has its private Fatal; E3(a) has its PIXEL assertion but the library
#                      never says the push was disabled (the half ID-65 added)
#   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
#
# EXIT GATE E2's DRAW-DROP CONTROL (scripts/ci/retrace_drop_draw_control.sh). The library's own
# log is modelled as a separate sink from ctest stdout, exactly as it is for the split lane: the
# console sink is compiled out of the configurations these lanes run, so the dropped-record count
# can only ever arrive through ${LIBRARY_LOG}.
#   dropdraw-noselect  `ctest -N` matches nothing
#   dropdraw-green     the retrace PASSES with the draws dropped
#   dropdraw-nossim    red, but no ssim summary at all (loader failure / timeout shape)
#   dropdraw-ssimhigh  red, and the ssim is ABOVE the threshold: something else reddened it
#   dropdraw-nolog     red with a low ssim, but the library never said the knob armed
#   dropdraw-zero      red with a low ssim, the knob armed, and it dropped NOTHING
#   dropdraw-evidence  red with a low ssim and N > 0 records dropped: the real thing
