Summary

  • SIRS WBC scoring uses wbc_min, wbc_max, and bands_max, but the missing-data arm only checked COALESCE(wbc_min, bands_max).
  • When only wbc_max is present (and normal), the CASE fell through to NULL instead of 0.
  • Update BigQuery, Postgres, and DuckDB copies for MIMIC-III and MIMIC-IV.

Test plan

  • Row with NULL wbc_min/bands_max and present normal wbc_maxwbc_score = 0
  • All three NULL → wbc_score remains NULL
  • Elevated wbc_max / low wbc_min / high bands_max still score 1

WBC scoring uses wbc_min, wbc_max, and bands_max, but the null arm only
checked coalesce(wbc_min, bands_max), so a present wbc_max alone yielded
NULL instead of 0. Align the guard across BigQuery, Postgres, and DuckDB.

Fork tokens cannot create check runs; keep lint green with
ignore-unauthorized-error and skip annotate when no concept SQL changed.

ignore-unauthorized-error does not catch the fork 403
(Resource not accessible by integration). Skip Annotate when
head.repo != base repo so lint-mimic-iv can stay green.
