All nine review findings closed at root (one sub-item consciously
deferred):
F1 the category dropdown now draws: sprites/fonts wired and the popup
geometry read from the vendor menu's own authored popup LayoutDesc
0x21000043 (root 0x1000034F — correcting the review's 0x1000014F
transcription) per UIElement_Menu::MakePopup (pc:120705); chat's menu
is untouched and its tests prove it. The new test drives selection
through the REAL open/hit path the review flagged as bypassed.
F2+F3 the selected-item cost display ports VendorItemsUI::UpdateItemsUI
verbatim: quantity via the 0xDC41CB0 split-size mask (whole-stack for
ammo, per-unit for groceries/components; mask lives at the toolbar
SEEDING site pc:198784), plural names with retail's
fall-back-to-singular (pc:409056 — correcting the review's "name+s"
guess), full cost sentences with comma grouping and the player's coin
total, and Buy/Add buttons that disable without a selection.
F4 category switches auto-select the first filtered item (pc:201180).
F5 icon underlay/overlay/effects + plural name forwarded from the
already-parsed wire fields through VendorShopItem to the icon
composer. F6 a DIFFERENT vendor opens on its own first category;
same-vendor refresh preserves per the clamp. F7 scroll resets on
rebuild and authored empty slots fill; the right-click examine route
is consciously DEFERRED (shop items are not in ClientObjectTable and
the appraisal panel hard-requires it — documented, not faked).
F8 VendorState.Apply's fanout gets the same per-listener isolation as
Close/Reset. F9 AP-110/AP-161 wording corrected ("quantity-correct
pricing") and AP-161 rewritten to exactly the remaining conscious
gaps.
Clean-room complete solution with the #348 cursor fix in the same
tree: 11,334 passed / 4 skipped / 0 failed.

The vendor window is retail's own: LayoutDesc 0x21000012, root
0x100000B7, found by enumerating all 101 layouts for the one
containing both known tab controls and clinched by the root's Type
0x10000017 — the literal UIElement::RegisterElementClass id for
gmVendorUI (pc:202075). Discovery evidence and the D0 read live in
the research doc's new §B.4.
D0 corrected two assumptions: retail's category "tabs" are a UiMenu
DROPDOWN fed by a hardcoded 18-row ordered category table (ported
bit-for-bit against our ItemType enum; list always scoped to exactly
one category, first-present wins, selection preserved across refresh
per retail's clamp), and the layout authors THREE tabs — Items
(browse, this slice), Buying and Selling (staged-transaction review,
Slice 6) — decision 4's "browse/Buy tab" names the Items tab retail's
mode-2 OpenTab opens. The non-default tabs render and switch pages
but stay inert, fenced in comments.
VendorUiController mounts Items: category dropdown, icon-cell item
row with the retained scrollbar, per-unit retail pricing via
VendorPricing.SellPrice (the vendor-stock path VendorProfile::
VendorSellPrice feeds), name/cost on selection. The panel is a pure
projection of VendorState — opens on populate, closes on clear; the
close button's VendorState.Close() is its only permitted mutation.
Nothing on the wire.
AP-110 narrowed (vendor leaves the absent-panels list); AP-161 files
the precise Slice-6 remainder (Buying/Selling unwired, Buy/Add
buttons, InqAcceptability). Twelve controller tests on a real-dat
fixture. Clean-room complete solution: 11,323 passed / 4 skipped /
0 failed.
