"""Verify the pileSizeClientData key enum before changing boot-critical massinfo.

Contradiction to resolve:
 - utas_server.py comment: pileSizeClientData is "the MY CLUB counter", enum
   "not recoverable", so it sprays the club count across keys 0..15.
 - workflow wf_29791945: parser FUN_18013adb0 has EXACTLY two arms, key 2 -> trade
   pile (response+0xd0 -> model+0x1fd1c = TRADE_PILE_SIZE, the red 0/0) and key 4 ->
   watch list (+0xd4 -> +0x1fd20). No club key. Spraying the club count (246) onto
   key 2 would set the TRANSFER-LIST CAPACITY to 246, which is wrong.

Only one can be right. Read the parser. If it has cmp esi,2 / cmp esi,4 and no
default store, the workflow is right and the current code is a latent bug.

CONTROL: the parser must be reached from the massinfo root via arm 0x227
(pileSizeClientData atom). Confirm the atom and the call.
