- the buff bar is the reference's own `BuffFrame.xml`, and the swap found an engine defect: an empty `<OnLoad>` in 1.12's XML is a BLANK that takes an inherited handler away again (seven such sites across four stock files), which our loader read as "none given" — so the two enchant slots would have painted the player's first buff in the corner and cancelled it on right-click; the first fix then had to be corrected at the bytes (`SetScript 0x7025c0` tests only NULL and empty, and nothing trims, so `<OnLoad>↵</OnLoad>` compiles to a valid empty function rather than storing nil, which any addon calling `GetScript` can observe); `SHOW_BUFF_DURATIONS` is applied once post-load because 1.12 leaves that to `UIOptionsFrame.lua`, which benilla does not build — without it the bar ships a 10px pitch error on every buff
- gossip quests come through the reference's four verbs — `GetGossipAvailableQuests`/`GetGossipActiveQuests` returning (title, level) PAIRS, with the two `Select*` verbs indexing into that list — replacing three invented names that sat on the beyond-1.12 exception list; the quest LEVEL was on the wire, parsed and dropped because the invented verb had nowhere to put it, and the reference's order (available before active, whatever the packet interleaved) comes with them
- eight more files off the chain as groundwork: `LocaleProperties.lua` (the gendered/plural `GetText` selector that eleven stock call sites read their words through — fifty lines of FrameXML that looked like an engine binding), `CinematicFrame.xml`, the UIMenu kit, the `UnitFrame.lua`/`CombatFeedback.lua` kits (the only two names blocking the stock player, party, target and pet frames), the money-input kit, and `ItemButtonTemplate.xml` — the base every bag, bank, merchant, loot, trade and mail slot inherits; `GetMerchantItemMaxStack` (on the wire the whole time, dropped) and the two trade item-link verbs join the engine
- two instruments for the migration: a gap report that reads a stock window's call sites against a LOADED VM and says which engine verbs it still needs (28 windows need none, the rest name 1–5), and the readiness probe's documented false positive — loading a stock window on top of our same-named one leaves `getglobal(name)` pointing at ours while the stock handlers run against theirs, so a failure inside a colliding name is a question, not an answer

- quest sharing lands whole: four opcodes, the Share button live with the reference's own predicate (registering the one party event it does for the one reason it does — joining a party changes the answer without changing the log), nine verdict lines for the sharer, and the escort confirm as its own dialog whose No sends nothing at all, because there is no decline packet for it; the push result's u64 means two things by direction — the sharer being answered going up, the member the verdict is ABOUT coming down — and the verdict stays a raw byte so an unmapped value shows the reference's own nothing rather than killing the packet
- the receiving half needs almost no code, and that is the design: the server sends an eligible member an ORDINARY quest-details packet whose giver guid is the sharing PLAYER, and Accept answers with the ordinary accept — a shared quest lands on the questgiver panel we already have, and the guid's own type bits drive the two real differences: declining a share owes the sharer a DECLINE verdict, and the panel is not held to the 5.56-yard NPC service range (the server's bound for a share is 14 yards, tested at accept)
- the fold-back corrected three things days-old code had just shipped: DeclineQuest and CloseQuest are ONE routine in the reference — what varies is the giver, not which button you pressed; declining an NPC's quest RE-OPENS its list — the session end sends the giver a fresh hello, refuting our five-month-old claim that "vanilla's client-side decline sends no packet" (and the details packet's trailing u32 we had parsed and ignored is exactly what suppresses that re-open) — so declining at an NPC now returns you to its menu instead of closing the window; and BUSY is the client's OWN verdict — a share arriving while any panel is open is refused client-side, covering the mid-turn-in case the server cannot see
