Fork policy (docs/METHOD.md): upstream structure wins; local-unique work re-applied on top. This commit is the upstream half of the reconciliation. Upstream is the same program at a rewritten history (884dff77==4e0e89cbtree), so the merge base was replaced to keep a real three-way diff. The large conflicts are upstream moving first: the UI manifest (benilla.toc -> the binary LAYER_MANIFEST/layer.toc split), the CVar table (cvars.rs -> cvars/{mod,table}.rs, +24 video rows), the editbox flush model, the host-side GetTime, the Options* -> BenillaOptions* rename, expanded ui_unit.rs, and a rebuilt volumetric_light.rs. Local-unique pieces re-instated on the upstream structure: - OptionsFrame.xml: the 1.12 OptionsFrameSliders table restored under the Benilla rename, with the TurtleWoW deviation note (patch-4 replaces OptionsFrame.lua). - layer.toc: CharacterFrameAdapters.xml (the sixth TurtleWoW character tab). - ui script: wipe/sizeof, BenillaGetMerchantItemStats, and the attach/mount teardown re-walk all survive. - game_plugins.rs keeps UPDATE_ACTIONABLE_CEILING=5_509 (re-measure pending). The LFT/Turtle_TransmogUI rows benilla.toc named off the player's install now come from the chain's own FrameXML.toc via the new core loader.

reference/: verified facts about the 1.12.1 client, vendored
Generated tables describing the reference client, committed so benilla can measure itself against
them on any machine without re-deriving them. Data, not documentation: each has a generator beside
it in scripts/.
Nothing here is Blizzard content. A catalogue of names is not the thing named, the same way a
comment may quote a byte address and docs/MAP.md may name a file.
1.12-globals.tsv
The 1.12.1 client's entire global namespace: 21,555 names, name<TAB>type<TAB>origin.
Where it comes from: a dump of _G inside the running reference client, which is the surface an
addon sees (FrameXML-defined globals as well as engine ones), unioned with every global the shipped
UI defines. The union matters because the twelve Blizzard_* addons are LoadOnDemand: a live dump
only carries their globals if their windows were opened first, so the 1,986 rows a dump cannot see
carry type lod. The table answers "is this a 1.12 name?", not "was this name live in one session".
The origin column says whose job it is to provide the name, attributed by its definition site in
the complete 1.12 shipped-UI corpus:
| origin | count | meaning |
|---|---|---|
engine |
1,104 | the C client provides it; benilla implements these in Rust |
framexml |
20,427 | the shipped UI defines it; the stock files run off the player's own install (ui_script::reference_ui) |
lua |
24 | Lua 5.0's own runtime |
The framexml bulk is UI objects, ContainerFrame1Item16IconTexture and its 11,000 siblings,
which materialize from the XML and are nobody's to implement. The number that matters for the API
surface is the function split: 1,100 engine functions, 1,075 FrameXML functions. A name defined in
shipped Lua is FrameXML's, and hardcoding it in Rust is a category error even when it works.
Regenerating: scripts/gen-reference-globals.py, whose header carries the method and the traps. It
needs a 1.12 install, its FrameXML extracted to a folder, and the maintainer's runtime capture of
the reference client's _G, which is not in this repo, so it is a manual regeneration. The table is
stable: it describes a client that shipped in 2006.
Reading it: scripts/api-coverage.sh asks a real UiScript::new() what benilla exposes and reports
have / missing / beyond-1.12. Two gates hold the line.
crates/benilla-ui/src/script/tests/reference_surface.rs fails if the engine puts a global 1.12
does not have in a bare VM and nobody wrote down why, with no prefix excusing an engine name.
crates/benilla-app/src/ui_script/surface_gate.rs fails if the production load, the core and
benilla's layer, adds any global past 1.12 other than the layer's own Benilla-prefixed names, or
any widget method.
1.12-shapes.tsv and 1.12-events.tsv
The binding-shape table (what each Lua verb takes and returns, gated by ui_script/shape_gate.rs)
and the event table with the arguments each producer pushes (gated by
ui_script/event_shape_gate.rs). Each file's header carries its column contract.
Regenerating: 1.12-shapes.tsv is vendored as the reference analysis writes it.
scripts/gen-reference-events.py derives 1.12-events.tsv from two more vendored tables,
1.12-event-catalog.tsv (event id to name, off the client's name-pointer array) and
1.12-event-firesites.tsv (every fire site with the format string it pushes), so it runs from any
clone and reproduces the committed file byte for byte.
1.12-message-catalog.tsv
The client's message registry (0xb4b498: id, key, kind, sound, chat type).
scripts/gen-message-catalog.py re-shapes it into crates/benilla-ui/src/messages/catalog.rs,
the table CGGameUI::DisplayError indexes.
1.12-verb-events.tsv
Every event the reference fires from inside a Lua verb, keyed by the verb: the verb's own body, or
a helper that only registered verbs call (0x4d8c90 is the trainer's). The two tables above say
what an event carries and whether something fires it; this one says who. A stock file that calls a
verb for its side effect of an event repaints nothing when the verb fires nothing.
Regenerating: scripts/gen-reference-verb-events.py, whose header carries the rule, the two
families it drops (glue-space verbs, the unit-field bridge) and why getters are excluded (a getter's
fire is a cache-miss re-query, a state event benilla's feeds fire off the packet). A fire site is
attributed to a function by the verified function extents plus the disassembly's padding
boundaries, and a site past its candidate's extent is left out rather than mis-filed. The fire
sites and the shapes are the vendored tables above; the function names, their extents and the
disassembly are the maintainer's, so this one is a manual regeneration.
Reading it: crates/benilla-app/src/ui_script/verb_event_gate.rs is the gate. For every pair whose
verb benilla registers, the module that registers the verb fires the event, or the pair is declared
there: ELSEWHERE (a feed fires it on the state the verb changes, and the named file is checked
too) or GAP (nothing does, with the reason).
