+May 18, 2026 2:36 PM - saved a copy of the SQLite database under sql/archive.  Memorialized prompt for Phase 2A from ChatGPT in Codex_prompt_State2A_20250518_1433.md.
+
+Trying to reconcile Codex's report of warnings vs. what I get, ChatGPT had me run several tests and I provided the results and it concluded:
+
+    Codex report showed “2 warnings,” but on jp the warnings were not reproducible.
+    Rerun with -W always -rw showed:
+    fragmentation backend shim: 9 passed, no warnings
+    Gate 2C/2D/2E regression: 39 passed, 1 skipped, no warnings
+    The single skip is expected and is not a warning.
