MyPageTask.Parse (Wizard/MyPageTask.cs:155-163) does
`_userItemDict.Clear();` the moment `user_item_list` is present in
the response body — not when it's non-empty — then re-populates
from the wire. Our /mypage/index was emitting [] by default (the
field initializer on the DTO), which wiped the inventory that
/load/index had just populated.
Downstream consequence: the client's PackChildGachaInfo.CostGoodsCount
reads from _userItemDict, so a wiped dict makes every ticket-cost
pack report CostGoodsCount=0, PackConfig.EnableBuyPack returns false,
and is_hide=1 packs (including the tutorial legendary starter 99047)
disappear from the rotation pack list — even though the gift bundle
just granted the ticket and the DB row exists. The tutorial then
auto-selects whatever non-tutorial pack happens to be at index 0 of
the filtered list, the user can't afford it, and the flow is stuck.
Fix:
- MyPageController.Index now sets UserItemList from viewer.Items
(already loaded by GetViewerByShortUdid's home-screen graph).
- DTO docstring rewritten to call out the presence-sensitive semantics
and the load-bearing path through PackConfig.EnableBuyPack, so the
next developer doesn't get the "empty is fine" hint the old comment
implied.
