 ### Database Schema
 
-**Note**: With Fava integration, Libra maintains a local cache of some data but delegates authoritative balance calculations to Beancount/Fava.
+**Fava is the sole source of truth for journal entries.** Libra does NOT maintain a local mirror of transactions — the previous `journal_entries` and `entry_lines` tables were removed during the Fava migration. All transaction reads (history, balances, summaries) go through Fava's HTTP API; writes go through `PUT /api/add_entries` and are serialized via `FavaClient._write_lock`. When retrieving journal entries from Fava for UI display, results are enriched with a `username` field from LNbits user data.
 
-**journal_entries**: Transaction headers stored locally and synced to Fava
-- `flag` field: `*` (cleared), `!` (pending), `#` (flagged), `x` (void)
-- `meta` field: JSON storing source, tags, audit info
-- `reference` field: Links to payment_hash, invoice numbers, etc.
-- Enriched with `username` field when retrieved via API (added from LNbits user data)
+The SQLite tables below hold **operational state** that Fava doesn't (and shouldn't) own — workflow, RBAC, settings, reconciliation assertions. None of it is derivable from the Beancount file; they are independent stores, not caches.
 
 **extension_settings**: Libra wallet configuration (admin-only)
