Coverage and confidence

Generated from the data files at build time. "Verified" means seen directly in code, data, game scripts or at run time; "inferred" means deduced from verified facts. Counts are for the symbol build mapped to the current build.

Available out of the box

Part	Total	How complete	How sure
Lua methods	1920	all registered methods; 1480 (77%) also appear in the community reference, 440 (23%) do not	registration is read from the DLL tables (verified)
Signatures	1920	988 (51%) have at least one parameter; 966 (57%) of 1709 parameters have a real name; 512 (30%) have a C++ type	1773 (92%) high confidence, 147 (8%) partial (marked ⚠)
Return values	1527 return something	1432 (94%) have a detailed description (tables, arrays, types); 141 (9%) have a stated meaning	meanings: 66 verified, 75 inferred
Argument meanings	1709 parameters	798 (47%) have a stated meaning	603 verified, 195 inferred
Operations and commands	154	all identified with hash, handler, addresses	137 verified, 16 inferred (16 handlers matched by class name), 1 unknown
Operation parameters	76 slots, 167 parameter entities	0 (0%) slots have an example from the game's scripts	entities: 73 verified, 94 inferred
Lua constant tables	25 tables, 546 members	the 6 operation and command tables are complete; 19 more tables are matched to engine enums through the Companion (only the members it lists are known to be exposed)	operation tables verified from the debug info; the 19 others inferred

Needs the Community Extension

Part	Total	How complete	How sure
Community Extension functions	33	all in its wiki; 17 (52%) linked to the engine function	wiki + source (verified)
Class layouts	1915 classes, 12022 members	all non-template GameCore classes in the Linux build	Linux offsets verified from debug info; 25 members checked against Windows code
Globals	1314	named globals present in both builds	801 verified (mapping rests on 2+ references), 513 inferred

Engine internals

Part	Total	How complete	How sure
Function inventory	43803 functions	33271 (76%) mapped to the current build; 21782 (50%) have a Linux signature	mapping method is described in the analysis notes (not yet part of this site)
Native function entries	367	17 analysed in detail (106 notes), 17 wrapped by the Community Extension	analysed notes labelled verified / inferred
Hand-written notes (all entity types)	39	a small curated set	22 verified, 17 inferred

Known gaps

Return and argument meanings exist where the game's own scripts reveal them; the remaining methods are listed with types only.
Signature columns marked ⚠ (147 methods) have arguments or returns we could not fully classify.
Only 25 layout members have a checked Windows offset; for the rest use the Linux offset with the stated rule.
The Events enum lists engine ids (not scriptable). 152 of the 352 are also Lua events with parameter names from the Civ VI Modding Companion (ChimpanG, WildW); see the Lua events page. These are community-sourced and not checked against the DLL.

Checked against a running game

Part	Total	Result
Lua methods seen on live objects (UI state)	825	453 called once: 439 returned the documented number of values, 8 returned nothing, 6 raised errors (each noted on the method page)

See the topic Checking the reference against a running game. Not covered: methods with arguments, mutators, the gameplay Lua state, multiplayer.
