The site linked prose citations through profile_sync, which made the site build depend on the checker. The prose runs and their patterns move to sourceref, the grammar module both read, and profile_sync re-exports them.
A profile that reads a libretro core and the original emulator cited both trees alike, and readers could not tell whether the core or the emulator asked for a file. A cited path now opens with source or upstream, the repository its lines are in. Emulator code a port carries is attributed upstream when the original holds the same value on the cited line.
profile_sync --attribute-refs writes the words from where the lines are found and follows a word already written. The site links each citation to that repository's pin, labels it libretro core or upstream emulator, and says on each file card whose code asks for it. A recale keeps the word, and mame_ref_audit reads the tree it names.
The site imported two parsing functions from profile_sync, so every change to the comparison tool redeployed an unchanged site. The grammar now lives in sourceref.py.
