benilla-octo/crates/benilla-app/assets/ui/ContainerFrameAdapters.xml

<!--
    OUR adapters over the reference's own `Interface\FrameXML\ContainerFrame.lua`.

    **This client does not transcribe that file — it EXECUTES it, off the player's own patch
    chain**, before any of our `assets/ui` files (`ui_script::reference_ui`, whose header carries
    the rule and the licensing reason: Blizzard's Lua is never committed here). What is in THIS
    file is only benilla's, and only where a reference body reaches for something this client
    genuinely does not have.

    The rule, restated in one line so it can be applied without re-reading the module: the sourced
    file's globals stand unmodified; ours (loading after) win where both define a name; and where a
    reference body needs a benilla answer, it is WRAPPED here — never silently stubbed.

    ── The one adapter, and why it is not a stub ────────────────────────────────────────────────
    `ContainerFrameItemButton_OnEnter` opens with a keyring fork (ref l.615-620):

        if this:GetParent():GetID() == KEYRING_CONTAINER then
            GameTooltip:SetInventoryItem("player", KeyRingButtonIDToInvSlotID(this:GetID()))
            CursorUpdate()
            return
        end

    That fork exists because the REAL client's keyring items are inventory slots, not container
    slots, so it has to detour out of the container API to describe one. benilla's keyring is an
    ordinary container (id -2, decision 0765): its slots come through `GetContainerItemInfo` and
    `GameTooltip:SetBagItem` like every other bag's. So the detour is not merely unavailable here
    (`KeyRingButtonIDToInvSlotID` is not a binding here; `CursorUpdate` now is, transcribed from
    UIParent.lua into UiPanels.xml, so only half the detour is missing) — it is *wrong* here,
    and supplying the two verbs would buy an empty tooltip, because our keyring items were never
    fed into the inventory-slot space it reads.

    So the wrapper below answers the keyring case the way benilla answers every other bag, and
    hands EVERY other slot straight to the reference's own body. The path the player is actually
    on — hovering an ordinary bag slot — runs the real client's code, unedited.

    ── Named, not hidden: what still does not work through the sourced file ─────────────────────
    · `MerchantItemButton_OnClick`. The reference's `ContainerFrameItemButton_OnClick` closes its
      shift-right-click-at-a-vendor arm with a `SplitStack` closure that calls that global, and
      benilla's merchant window publishes `BenillaMerchantItem_OnClick` instead. Confirming a stack
      split with a vendor open therefore raises. That is the same "a Benilla name shadows the
      reference's" class this whole seam exists to close, one window over, and it is left loud
      rather than guarded (1203): the fix is to publish the merchant global, not to hide the call.
    · `REPAIR_COST` is read by the reference's repair-mode arm. It is a `GlobalStrings.lua` key and
      this client sources that file too, so it resolves at runtime — and the arm is unreachable
      today regardless, since `GameTooltip:SetBagItem`'s repairCost is an INTERIM 0.
