- the pet stable and the flight map are the reference's own files: `TaxiRouteFrame` maps to a plain Frame (factory `0x495ba0` allocates the base size, the ctor adds no field, no new virtual, no method table — and `GetObjectType` is not overridden, so its own kind would have been the divergence), and the swap found three silent behaviours — the close button did nothing (an unknown `inherits=` is a WARNING, so it loaded as a bare button), the "no paths" line drew empty, and the title is READ off `UnitName("npc")`, not received; the WMO skybox rides the interior crossfade — one weight (`[0xce9bdc]`, the same number the MFOG lerp rides), a 4 s alpha fade, so a skybox the flood publishes through a doorway draws at weight 0 instead of popping in whole
- a widget predicate answers the NUMBER 1 or nil, never a boolean: eleven of them (`IsShown`, `IsVisible`, `IsMovable`, `GetChecked`…) move to the 1.12 shape — the reference proves it in its own source (`tostring(this:GetChecked())` saved and read back `== "1"`; `tostring(true)` would never match and buff timers would never appear), 21 corpus sites compare directly (`IsVisible() == nil`, `GetChecked() == 1`), and one of our own tests had the guild rank editor sending `true` where a real client sends 1
- the vendor's refusals are the reference's table: `SMSG_BUY_FAILED`/`SMSG_SELL_ITEM` route through `0x5dcd60`/`0x5dd1f0`'s switches, six lines were wrong (code 3 printed "That vendor can't be found." — vmangos's identifier — where 1.12 prints "That merchant doesn't like you."), silence is now expressible, and keying them gives the vendor a voice (`ERR_NOT_ENOUGH_MONEY` carries error-speech line 0x28); the bank's three ids were right and its "purchase failed (n)" an invention; the logout refusal is one key, `ERR_LOGOUT_FAILED`, for every non-zero reason; the two mail codes we said had no string have one (`ERR_PLAYER_WRONG_FACTION`, `ERR_RESTRICTED_ACCOUNT`) and a sent mail says `ERR_MAIL_SENT` in yellow; a test runs the chain's own `GlobalStrings.lua` and requires non-empty text for all 193 `ERR_*` the workspace names
- a clicked quest timer no longer raises — stock `QuestTimerFrame.lua` calls `QuestLog_SetSelection`/`QuestLog_Update`, which existed nowhere in this tree; our quest log owns the reference's two names now, which also shrinks the delta when that window itself migrates
