+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Text shapes created with the "T" text tool show up on the creating client but not on other clients viewing the same board.
+
+Root cause investigation:
+- Text shapes ARE being persisted to R2 (confirmed in server logs)
+- Issue is on receiving client side in AutomergeToTLStore.ts
+- Line 1142: 'text' is in invalidTextProps list and gets deleted
+- If richText isn't properly populated before text is deleted, content is lost
+
+Files to investigate:
+- src/automerge/AutomergeToTLStore.ts (sanitization logic)
+- src/automerge/TLStoreToAutomerge.ts (serialization logic)
+- src/automerge/useAutomergeStoreV2.ts (store updates)
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [ ] #1 Text shapes sync correctly between multiple clients
+- [ ] #2 Text content preserved during automerge serialization/deserialization
+- [ ] #3 Both new and existing text shapes display correctly on all clients
+<!-- AC:END -->
