## A lockout template shapes its plans
A template can now decide whether its plans carry a Priority field and which levels it offers, and it can lock the isolation point list so plans built from it cannot add or remove points. Both are off by default, so existing templates behave exactly as before.
## Impact Simulation on the single-line diagram
Open a plan's Impact View and the diagram shows what the isolation actually affects, scoped to the equipment the plan involves. The assessment exports to PDF.
## Nudge the authorising signer
When a plan is waiting on its post-check authorisation, a Notify button sends the named signer a message and an email with a link to the plan. Repeated nudges are spaced out automatically.
## Fixes and improvements
- Lockout emails now name the person who acted.
- The single-line drawing is easier to read: cards state their parent instead of drawing long tethers, and the legend shows only what the drawing uses.
- A small number of bug fixes.
- Security and dependency updates.
