- four return shapes were wrong — `UnitPowerType` returns ONE value in 5875 (the Era `(type, "RAGE")` pair does not exist, and its miss arm pushes the NUMBER 0, which `UnitFrame.lua:122` indexes `ManaBarColor` with), `UnitName` returns `(name, server)`, `GetTexCoord` returns EIGHT (ours four — a shape that exists nowhere, with zero call sites in FrameXML, so only the binary could have caught it), `GetLootMethod` answers `freeforall` ungrouped — the fifth right-name-wrong-arity finding in two days, so wow-re's `binding-shapes.tsv` (1722 rows over all 82 registrar tables) is vendored and a gate probes every binding's arity against it: 313 probes, eight divergences (seven global, one widget); `GetBuildInfo` pushed a fourth value no 1.12 client does (458 corpus sites take one, the four that destructure a fourth read nil on the real client), `GetAddOnInfo` RAISES on a numeric index, `Model:GetFogColor` is a packed `0xAARRGGBB` dword with no unset state, and the five miss branches are the reference's exact tuples
- the panel-template kit is the reference's own `UIPanelTemplates` pair (our 18 templates were a strict subset — `TabButtonTemplate` and the `ScrollingEdit_*` family arrive, which unblocks the macro window and HelpFrame), and the swap found two structural facts: `FauxScrollFrameTemplate` is a `<ScrollFrame>` while every instance we declared was a `<Frame>` (fifteen elements across twelve files), and an instance `<OnLoad>` REPLACES the template's — four FriendsFrame lists set `updateFunc` in their own OnLoad, so `ScrollFrame_OnLoad` never ran and guild/friends/ignore/who had been silently painting nothing behind a `frame.offset or 0`
- the options widget kit (`OptionFrameBoxTemplate`, `OptionsButtonTemplate`, `OptionsCheckButtonTemplate`, `OptionsSliderTemplate`) comes off the chain too, giving back the reference's own per-widget hover; one template of ours stays because `UIOptionsFrame.xml` is not built here, and the lesson is general — when a file SHRINKS rather than dies, every harness that named it gains the chain entry beside it, not instead of it
