# RAIL-FAB-WP-ADHOC-2026-05-25 - Ad Hoc Fixes

## Add Zone Layout Algorithm Control

```task

status: done
priority: medium
state_hub_task_id: "15d1dbb0-9327-5692-ae3b-9e2ee37aae8a"
```

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.
