Current Product Backlog

This document records the next agreed product improvements. It describes requirements and intended sequencing, not proof of implementation.

Circuit List Editor

Collect the remaining editor interaction issues before changing additional behavior.

Every listed logical snapshot, including automatic snapshots, must be explicitly restorable from the project history UI.
Show which project change produced a snapshot. Prefer immutable revision metadata over storing a second free-form description of the same change.
Keep restoration auditable as a new project revision and preserve persistent undo/redo.

Assign an optional project floor to a distribution board.
Store a supply classification for each distribution board:
- AV (Allgemeine Stromversorgung)
- SV (Sicherheitsstromversorgung)
- EV (Ersatzstromversorgung)
- USV (Unterbrechungsfreie Stromversorgung)
- MSR (Mess-, Steuerungs- und Regelungstechnik)
- SiBe (Sicherheitsbeleuchtung)
Let project settings select which catalog supply types are used in a project. Distribution-board dialogs offer only that selection; a type in use cannot be disabled.
Include both fields in project snapshots and portable project export/import.
Persist changes through project commands so they remain undoable after a restart.

Derive voltage from the selected phase type and the project settings:
- single-phase uses the project's single-phase voltage;
- three-phase uses the project's three-phase voltage.
Apply this default consistently when creating global devices, project devices and manual circuit-list entries.
Define explicit override behavior before implementation so a user-entered exceptional voltage is not silently overwritten when phase type or project settings change.

The Revit/CSV/IFCGUID round-trip remains a separate jointly planned phase and must not be inferred from these tasks.
