+# ADHOC-2026-05-25 - Ad Hoc Fixes
+
+## Add Zone Layout Algorithm Control
+
+```task

+```
+
+The graph explorer now lays zone subgraphs out as a grid inside each zone
+container. Add an operator-facing control that can switch the zone-local layout
+algorithm while keeping stable zone containers intact.
+
+Expected result: the map controls expose a zone layout selector, the selected
+algorithm applies to each zone subgraph, and the setting persists in saved or
+copied view state.
+
+Result: Added a `Zone Layout` selector with Grid and Circle algorithms. The
+selected algorithm is stored in nested zone view state, reflected by the
+`zoneLayout` URL alias for non-default layout, and reapplies zone-local node
+placement without moving stable zone containers.
+
+Verification:
+
+- `python3 -m pytest tests/test_graph_explorer.py tests/test_zone_view.py -q`
+  passed.
+- Generated graph explorer JavaScript passed `node --check`.
+- `python3 -m railiance_fabric.cli validate .` passed.
+- `python3 -m pytest -q` passed with 72 tests.
+- Headless Edge screenshots confirmed Grid and Circle zone layouts render.
