 **`--cc1-flag=X` REPLACES the default `-quiet -O2 -G0` set.** A's first `-fthread-jumps` probe came back
 200 bytes purely because `-O2` had been dropped, which reads like a codegen disaster and is only a
 flag-set replacement. Any diagnosis run must pass all four flags explicitly.

+### A wrong count in my own commit message, corrected here
+
+Commit `354e90d`'s message says "670 bodies / 680 regions". **The true figures after that merge are
+672 bodies / 681 regions.** I wrote the message's headline from the pre-merge number in my head instead
+of from the command output in front of me, and the merge then added three more rows
+(`0x80107CCC`, `0x8002D060`, `0x8006FAEC`).
+
+Not rewriting history for a number, but recording it, because **a wrong body count in the commit log is
+exactly the kind of figure a later session trusts without re-deriving**, and the phase's whole
+projection rests on this number being the one the gate produced. The authority is
+`config/regions.tsv` counted at the merge, and that said 681 regions / 672 bodies.
