+## Terminology (hard)
+
+- The word **"murder"** is never stated in chatroom copy, docs, UI or event payloads. **"so many crows"** is the standing allusion to the collective — the app's name carries it. The pipeline's legacy `"murder"` JSON constant stays until Epic A's role decisions retire it (grandfathered: it is a live API contract).
+- The chatroom mode where several crows take one task for distinct perspectives is **conspiracy** (noun: "a conspiracy of crows"), never a verb.
