Field note
One mechanism, many names
Njangi, susu, chit, tanda, paluwagan, and hui are not decorative synonyms. Each name arrives with people, place, and practice.
Share structure carefully
Many circles use regular contributions and a rotating payout, but a product should not assume every circle follows identical rules. RAITON gives the circle a vocabulary for members, rounds, contributions, and turns while leaving its actual terms in the circle’s hands.
Let specificity survive scale
The interface can be consistent without renaming the communities it serves. Cultural names belong in the story, not as borrowed ornament.
