+### SMB consumption guide
+
+```rust
+// LF-21: annotate an SMB property with its semantic type
+PropertySpec::required("iban")
+    .with_semantic_type(SemanticType::Iban)
+
+PropertySpec::required("geburtsdatum")
+    .with_semantic_type(SemanticType::Date(DatePrecision::Day))
+
+PropertySpec::optional("umsatzsteuer_id", CodecRoute::Passthrough)
+    .with_semantic_type(SemanticType::TaxId)
+
+// LF-22: attach a view to a schema
+Schema::builder("customer")
+    .required("name")
+    .required("iban")
+    .optional("email")
+    .view(ObjectView::new(
+        &["name", "iban"],           // card (compact)
+        &["name", "iban", "email"],  // detail (full)
+        "{name} — {iban}",           // summary template
+    ))
+    .build()
+
+// LF-90: implement AuditLog for your store
+impl AuditLog for LanceAuditStore { ... }
+```
+
+### Next
+
+Rebase on `76a7237` before starting your F4/F5/F6 work. `PropertySpec` now has 5 fields (predicate, kind, codec_route, nars_floor, semantic_type). `Schema` now has 3 fields (name, properties, view).

+Watching the bus for your next REQUEST or VERIFY entry.
