- the help window is the reference's own `HelpFrame.xml`, and ours was less than half its size, so this is mostly arrival: the category list, the per-category GM and harassment pages, the stuck page, the bug report, the PvP policy line; four things we had built go with the swap — one-click filing from Home, the Home unstick button, the downed-queue refusal message, and ticket abandonment, a capability loss rather than a look change, since `AbandonTicket` exists in neither the binding table nor the 1.12 FrameXML corpus and any return of it goes on top of the stock window; `GMSURVEY_DISPLAY` arrives with no producer, a real 1.12 event (`SignalEvent` `0x5e797b`) whose whole UI is a LoadOnDemand addon not on our chain; and the stock file needs two orderings ours did not, the micro-button row before its GM status ask and the buff frame before its repoll timer (1889, superseding 1687)
- the cast bar, the action-button regions and the font registry are the reference's own files too: our `CastingBar.xml` was `CastingBarFrame.xml` under another name, with the literal "Failed" where the reference reads the `FAILED` GlobalString (1886); `ActionButtonTemplate.xml` seats above our `ActionBar.xml` because the later-registered template wins, and it declares zero scripts, so the regions migrate while the handlers stay ours until `ActionButton.lua`'s verbs do (1887); `Fonts.xml` is manifest entry 0, all 51 fonts match by name, and its one real difference, `ITEM_QUALITY_COLORS`, moves to UIParent where the reference declares it (1888); the harnesses were the real cost — those reading our files off disk could not name a chain file and now read through the manifest's own rule — and the event-producer gate, having cried wolf at the cast bar's `SPELLCAST_INTERRUPTED` fired through a variable, now matches the fired tuple's shape
- of the 189 events benilla fires, three are not in the client — `BAG_UPDATE_DELAYED` (a Classic Era name), `LOOT_UPDATE` and `UPDATE_LOOT_ROLL` (invented here, no listener anywhere) — found against the reference binary's own string table, and a gate now fails any fire of a name the client cannot dispatch unless it wears a `BENILLA_` prefix (1883); two payloads the reference gives that we did not: `UNIT_HAPPINESS` carries its unit token, without which no `UNIT_*` consumer reads it, and `CHARACTER_POINTS_CHANGED` carries the point deltas `ChatFrame.lua` compares unguarded, so nil raised (1884); and `PLAYER_LEVEL_UP` carries all nine — level, health and mana gain, talent points (not on the wire: the client derives `(newLevel >= 10) ? 1 : 0` at `0x5e407c`) and the five stat gains — matched to the ding by level, a demotion's absent gains sent as zeros since a nil raises where a zero reads as no line
- the chain gap report could not run — one of its six probes had no player seated where a stock addon formats `UnitName("player")` at load, the other five each carrying an identical copy-pasted seed — and the repaired instrument prices each window's cost: 13 stock files load clean with nothing missing (the action bars, the cast bar, the fonts, the help, friends, game-menu and sound-options windows among them) and the near ones name their missing verb, with "loads clean" still not "swapped" (1885); and `UpdateNameplates`, recorded as the missing engine verb blocking the UIParent keystone, is FrameXML — defined in `UIOptionsFrame.lua`, absent from the binding table, its whole body four nameplate verbs that are already ours — so it is twelve lines transcribed into our options frame, the reference's own Show-then-Hide no-op included (1890 corrects 1878)
