+* Models-as-data flow summaries now use fully qualified field names (for example, `MyNamespace::MyStruct::myField`) instead of unqualified field names such as `myField`. We recommend updating existing flow summaries to use fully qualified field names. Unqualified field names are still supported, but that support will be removed in a future release.

+* Type tracking of values stored in instance attributes and read from outside the class (for example `instance.attr` where the value was assigned to `self.attr` in a method) no longer relies on a dedicated instance type-tracker. This avoids a structural mutual recursion that could cause catastrophic query slowdowns on some OOP-heavy code bases. Such reads are now resolved using local flow from the constructor call, which is slightly less precise for instances that flow across a call or return before being read.

 ### Embedded Rust expressions
 
-`{expr}` embeds a Rust expression that returns a single node `Id`:
+`{expr}` embeds a Rust expression whose value is appended to the
+enclosing field (or to the rule body's id list). Dispatch happens via
+the [`IntoFieldIds`] trait, which is implemented for:
+
+- `Id` — pushes the single id.
+- Any `IntoIterator<Item: Into<Id>>` — extends with all yielded ids
+  (covers `Vec<Id>`, `Option<Id>`, iterator chains, etc.).
+
+So the same `{expr}` syntax handles single ids, splices, and zero-or-many
+options uniformly:
 
 ```rust
 (assignment
-    left: {some_node_id}       // insert a pre-built node
+    left: {some_node_id}       // a single Id
-    right: {rhs}               // insert a captured value (inside rule!)
+    right: {rhs}               // a captured value (inside rule!)
 )
-```
 
-`{..expr}` splices a `Vec<Id>` (or any iterable of `Id`):
-
-```rust
 yeast::trees!(ctx,
     (assignment left: {tmp} right: {right})
-    {..extra_nodes}                        // splice a Vec<Id>
+    {extra_nodes}              // splices a Vec<Id>
 )
 ```
 
-Inside `rule!`, captures are Rust variables, so `{name}` inserts a
+The contents of `{…}` are treated as a Rust block, so multi-statement
-single capture (`Id`) and `{..name}` splices a repeated capture
+expressions (with `let` bindings) work too:
-(`Vec<Id>`).
+
+```rust
+(assignment
+    left: {tmp}
+    right: {
+        let lit = ctx.literal("integer", "0");
+        tree!((binary_expr op: (operator "+") left: {tmp} right: {lit}))
+    })
+```
+
+Inside `rule!`, captures are Rust variables — `{name}` works for
+single, optional, and repeated captures alike:
+
+```rust
+rule!(
+    (assignment left: @lhs right: _* @parts)
+    =>
+    (assignment left: {lhs} right: (block stmt: {parts}))
+)
+```
+
+### Raw captures (`@@name`)
+
+The default `@name` capture marker is *auto-translated*: in OneShot
+phases the macro recursively translates the captured node before
+binding it, so `{name}` in the output template splices a node that
+already conforms to the output schema.
+
+For rules that need the raw (input-schema) capture — typically to read
+its source text or to translate it explicitly with mutable context
+state between calls — use `@@name` instead. The body sees the original
+input-schema `Id`:
+
+```rust
+yeast::rule!(
+    (assignment left: (_) @@raw_lhs right: (_) @rhs)
+    =>
+    {
+        // raw_lhs is untranslated: read its original source text.
+        let text = ctx.ast.source_text(raw_lhs);
+        // rhs is already translated by the auto-translate prefix.
+        tree!((call
+            method: (identifier #{text.as_str()})
+            receiver: {rhs}))
+    }
+);
+```
+
+Mix `@` and `@@` freely in the same rule. In a Repeating phase both
+markers are equivalent (auto-translation is a no-op for repeating
+rules).
