+**The cart is not committed. So conversion does not archive it — it deletes it.**
+*Every earlier version of this agreement was wrong about that by accident: a
+committed cart left its dailies in history, and "gone" was only ever true of the
+tree.*
+
+> **At conversion the cart is the only copy of everything in it.** *The dailies,
+> the annotations, the answers to every prompt, and the write-ahead log.*
+
+**So before converting, extract:**
+
+- **every answer to a `Question`, `Select` or `Affirm`** — *an answer lands in a
+  notes file, a notes file dies at dissolve, and an untracked cart has no history
+  to fall back on.* **A prompt answered and not extracted was never answered.**
+- **every write-ahead entry that survived** — *promote or discard, and both are
+  acts.*
+- **every fallback that quietly became the decision** — *say so in the entry, in
+  those words.*
+
+**Staging as you go turns conversion into a move rather than a rewrite.** *Keep
+the write-ahead log current during the round and there is nothing to reconstruct
+at the end, which is when you have least appetite for it.*
+
+*Two rules in this agreement now both push toward loss — **act as if the shelf is
+discarded daily**, and **the cart is not committed.** They are both right and
+together they mean **nothing in a cart is safe by default.***
