     Build the 10-byte params block that carries a single token byte.
 
     Used for SUBs 1E (EVENT_HEADER) and 1F (EVENT_ADVANCE).
-    The token goes at params[6], which maps to payload[12].
+    The token goes at params[7], which maps to payload[13].

+    Confirmed from BOTH 3-31-26 and 4-3-26 BW TX captures:
+      raw params bytes: 00 00 00 00 00 00 00 fe 00 00
+      token is at index 7 (not 6 — that was wrong).
 
-    Confirmed from 3-31-26 capture:
       - token=0x00: first-event read / browse mode (no download marking)
       - token=0xfe: download mode (causes 1F to skip partial bins and
                     advance to the next full record)
 
+    The device echoes the token at data[8] of the S3 response (payload[13]),
+    distinct from the next-event key at data[11:15] (payload[16:20]).
