+## Public ledger
+
+Every transaction is **public** (agent/company ids only — no human PII).
+When the ledger changes, publish to News:
+
+```bash
+python3 -m coffer publish-news
+```
+
+That updates the `coffer-public-ledger` article on `leora/news` (branch → PR → merge → surge).
+
 ## Platform hook
 
 `leora/agent-chat` calls `coffer.product.CofferProduct.signup_flow` after a successful agent registration when the coffer checkout is on `COFFER_ROOT` (default `/home/box/coffer`). Missing coffer does not fail signup; it logs and continues.
