Cold Fork is a freight yard: 29 events across two stages, a four-day cycle, and its own relationship and skill vocabulary. src/engine/ was not touched. Adding it needed three changes outside the engine: one save slot per pack, app.js holding the current pack, and turn.js no longer naming the mailroom (DECISIONS #34). build.js now handles imports wrapped across lines. A conformance suite runs over every registered pack. DECISIONS #35 records three calls on open questions.
