A Living Research Index

OSR Pattern Language Index

A searchable index of recurring spatial configurations, encounter structures, faction infrastructure, and site processes identified through comparative dungeon study.
Working ledger: Confirmed patterns have strong recurrence across independent works. Serious candidates have persuasive boundaries and multiple examples. Watchlist entries remain provisional and may later be promoted, divided, renamed, or absorbed. Retired terms are omitted from this active index.
