 # Completed slices
 
+## Dev-Rewrite multi-language Logic and traceable browser
+
+### Changed
+
+- Added pinned Tree-sitter-backed JavaScript and C++ analyzers behind the existing
+  language-neutral `LogicProjection` boundary.
+- Replaced ambiguous merge terminology with decision, case, loop-exit, and exception convergence.
+- Added composable text, family, node-kind, language, and capability filters plus common presets.
+- Added direct-neighbor and incident-edge highlighting when a canvas node is selected.
+- Increased Logic layer clearance and vertical spacing, with routed edge lanes for branches,
+  returns, and loop-back paths.
+
+### Verification
+
+- Tests cover JavaScript and C++ functions, methods, branches, short-circuit booleans, loops,
+  cases, exceptions, and returns alongside Python behavior.
+- Visualization tests cover filter facets, capability filtering, trace controls, template
+  identity, and browser asset validity.

 ## Dev-Rewrite function-scoped Logic
 
 ### Changed

 - Added dedicated schema-2 SQLite tables for function-scoped logic owners, nodes, and edges without
   placing statement-level data in primary graph search or traversal.
 - Added the bounded `docforge_get_logic` read tool and a lazy Logic visualization tab.
-- Added semantic Entry, Decision, Action, Control, Merge, and Terminal cards with explicit branch,
-  loop, exception, return, and raise paths.

 - Added Logic-specific hiding that bridges retained predecessors and successors with an explicit
   omitted path.
 - Preserved Release 1 adapters and full projections. Adapters may emit no logic or opt in source by
