the numerals kit goes stock, and a chat link is its own mouse target

- the status-bar numerals kit (`TextStatusBar.xml` + `.lua`) is the reference's own, and the attempt found a class of silent failure: `TextStatusBar_Initialize()` takes no argument in 1.12 and acts on `this`; ours took an optional bar, our unit frames passed one, and the reference's version ignores it — so the numerals would simply never appear, no error, nothing missing; seventeen of our signatures differ from the reference's that way (Lua drops a surplus argument in silence), written down before their files migrate, and the three "ours narrower" ones — `StaticPopup_Hide(which, data)`, `StaticPopup_FindVisible`, `WorldMapButton_OnClick(button, frame)` — closed now, because that direction bites when a STOCK file arrives and calls our version
- a chat link needs no mouse on its frame: wow-re read the client's ctors as mouse-enabling Button, CheckButton, Slider, ColorSelect and EditBox and NOT the scroll frames; the objection ("something makes a 1.12 chat link clickable") resolved as the engine synthesising one mouse-enabled `CSimpleHyperlinkButton` per link span (`0x7a3240`) — so a link span is a hit-test candidate on its own, the chat window is inert everywhere else, and the wheel is its own predicate rather than a borrowed mouse bit; seven `*ScrollFrame` known divergences retire
- the relic fit rule: `IsValidForSlot`'s slot-17 leg is an EQUALITY — `(InventoryType == RELIC) == hasRelicSlot` — so a relic lights the ranged slot for a druid and a bow does not, on the bag bar and the paper doll alike; closing it half-right would have lit the highlight for a druid dragging a bow
- a chain `.xml` whose `.lua` never loaded: `MoneyInputFrame.xml` had been on the chain without its `.lua`, so the template loaded and all ten `MoneyInputFrame_*` verbs read nil, silently — a gate now fails any chain `.xml` whose `.lua` sibling is neither sourced nor listed; the gap report's LOAD column carries the probe's collision caveat, its fx column stops crying wolf (it follows `<Script file=>`, stops reading `.Field(` as a global, subtracts a file's own locals), and a window is its xml PLUS the lua it sources
