 """Sylpheed static-analysis helper over DuckDB `sylpheed.db`.
 
 Hides the gotchas: DECIMAL bounds (DuckDB rejects 0x literals), read-only connect,
-and the fact that the engine vtable / rdata is NOT in the DB (read it from guest
-memory with `xenia-rs exec ... --dump-addr=0x<va>` instead).
+and the fact that the engine vtable / rdata is NOT in the DB.
+
+🔴 THAT LAST LINE USED TO SAY "read it from guest memory with
+`xenia-rs exec ... --dump-addr=0x<va>`". That emulator is retired, and the
+command no longer exists -- see docs/agents/CONSOLIDATION.md. Two replacements,
+both static, neither needing anything to run:
+
+  * the extracted PE is a FLAT VA DUMP: byte offset = VA - 0x82000000, so
+    `dd`/`xxd` on `*.pe` reads any address directly;
+  * `sylph-xexdb extract <xex>` regenerates that `.pe` (byte-identical, verified)
+    alongside a metadata JSON.
 
 Usage:
   zq.py dis  <lo_hex> <hi_hex>      # disassemble [lo,hi)  (jump-table words shown as .long)
