+## What this repository will not change
+
+MIMIC-Code does **not** rewrite `edstays.intime` from Pyxis or prescription
+minima. Correcting institutional clock skew belongs in a derived concept with
+an explicit rule, not in the build scripts that load the PhysioNet CSV files.
+Questions about BIDMC bedside workflow beyond what the tables encode belong on
+the PhysioNet forum, not as silent ETL patches here.
