심각도 말고 수명으로 갈라

verdict: "the script says 'yesterday' about turns three minutes apart"

  is this true about ONE run?              no - any run can do this
  can it be expressed as a check?          yes - measure the real span
  ---------------------------------------------------------------
  -> PROMOTE. becomes a hard check in the pipeline.


verdict: "candidate 3 had a distracting background, used 2 instead"

  is this true about ONE run?              yes - one asset, one episode
  can it be expressed as a check?          no - it is a taste judgment
  ---------------------------------------------------------------
  -> STAYS WITH THE RUN. discarded with the working directory.


verdict: "we cut the politically adjacent opening; the argument survives"

  is this true about ONE run?              yes
  does it explain the shape of the piece?  yes
  ---------------------------------------------------------------
  -> SUMMARY. goes on the request thread with the delivery.

# The pilot narrated "yesterday" about exchanges minutes apart,
# because the source material used that word and it was inherited
# without checking. Prose guidance would have been forgotten.
# Instead:

DAY_WORDS = ("yesterday", "어제", "last night", "the next day")
