Mac 0x00076e4c currently has an undefined result. Every normal return deliberately produces the byte from the existing act producer, or zero IF the diagnostic call returns. Use the existing one-byte eAct enum (ACT_I..ACT_V, values 0..4). Keep the selected name, unknown calling-convention label, zero formals and no-varargs model exactly; this claim does not recover ABI or hidden inputs. Nine recorded bodies total 507 code bytes plus 20 bounded threshold bytes. Native room/level/act code and the actual caller's AL projection support the semantic enum. The downstream GFX function has no local argument read, while its inner implicit register use remains unqualified; no GFX formal or global used/discarded claim follows. Global pointer contents were not captured and are not counted. No helper, caller, global, shared type, name or convention edit, numeric fallback, execution, original Mac-file hash or build-gain claim.
