The Lua VM keeps no surface the 1.12.1 client lacks.
- **Removed:** the nine Era-only globals: `UnitAura`, `CancelUnitBuff`, `GetCursorInfo`, `GetInventoryItemID`, `GetPlayerFacing`, `GetTradePartnerName`, `IsGossipOptionCoded`, `UnitIsAFK`, `UnitIsDND`.
- **Hooks off Lua:** `GameTooltip:BenillaSetItemById` and `:BenillaGetTooltipOwner` are replaced by Rust-side calls. The uncalled `Benilla*` hooks are deleted.
- **Frame strata:** `SetFrameStrata` knows the reference's eight strata and raises its message for any other (`0x774450`).
- **`SetDrawLayer`** reads the layer name alone (`0x79a780`).
- **`Set<State>Texture`** reads a number as a path (`0x781b23`); there is no colour form.
- **`PlaySound`** names a kit and returns nothing (`0x4586d0`). `PlaySoundFile` returns one value (`0x458780`); benilla answers 1, a recorded deviation, since it plays after the call.
- **`OnClick`** sets only `arg1` (`0x779540`).
- **Quest getters:** `GetQuestItemInfo` and the quest-log reward and choice getters answer the reference's five values and its miss behaviour (`0x501f80`, `0x4e0b00`, `0x4e0cf0`).
- **`PickupContainerItem`** returns nothing (`0x4f9b30`).
- **Surface gates:** the bare VM's globals and every widget class's methods are held to `reference/1.12-globals.tsv` with one commented allowlist. A new gate on the full production load (core plus layer) allows beyond that only the layer's `Benilla`-prefixed globals.
Verified:
- A test per removal and per corrected form; a scripted undo of each fails its test.
- Each gate fails on a re-added name.
- `scripts/gates.sh` and `scripts/smoke.sh` are green.
- A live run showed the same warnings and 0 script errors before and after.
- In the 219-addon corpus, AckisRecipeList's bundled AceGUI-3.0 and Roid-Macros' Grid extension now behave as they do on 1.12.1.
Built on macOS; no platform seam touched.
