+# Databrowse
+
+SQL data browser. Connects to a database, reads its schema from config, and provides a navigation and query interface.
+
+**Status:** ready
+
+---
+
+## What It Does
+
+Databrowse is a monitor, not a tool. It runs continuously and lets you browse database contents through a web interface. Navigate tables, inspect rows, run saved queries.
+
+The core is generic SQL. Room configuration defines the schema and saved views.
+
+## Structure
+
+```
+soleprint/station/monitors/databrowse/           # Core (generic SQL browser)
+cfg/<room>/soleprint/station/monitors/databrowse/depot/  # Room config
+```
+
+## Configuration
+
+Room-specific config lives in the depot directory.
+
+### schema.json
+
+Defines tables, fields, and relationships:
+
+```json
+{
+  "tables": [
+    {
+      "name": "users",
+      "fields": [
+        {"name": "id", "type": "integer", "primary": true},
+        {"name": "email", "type": "string"},
+        {"name": "created_at", "type": "datetime"}
+      ],
+      "relationships": [
+        {"field": "id", "target": "orders.user_id", "type": "one_to_many"}
+      ]
+    }
+  ]
+}
+```
+
+### views.json
+
+Defines saved queries:
+
+```json
+{
+  "views": [
+    {
+      "name": "Recent Users",
+      "query": "SELECT * FROM users ORDER BY created_at DESC LIMIT 50"
+    },
+    {
+      "name": "Active Orders",
+      "query": "SELECT * FROM orders WHERE status = 'active'"
+    }
+  ]
+}
+```
+
+## Separation
+
+Core provides:
+- SQL connection handling
+- Table navigation UI
+- Query execution engine
+- Relationship traversal
+
+Room provides:
+- `depot/schema.json` -- table definitions
+- `depot/views.json` -- saved queries
+- Database connection credentials
+
+The core knows nothing about your domain. The depot tells it what to show.
