 This repository contains a web application for creating, editing, calculating, and documenting electrical power balances for building-services electrical planning.
 
 The application is intended for small internal use by approximately 2–3 concurrent users. It should support practical planning workflows, not an over-engineered enterprise architecture.

 - By default, the table should initially hide: power factor (cos phi), phase count, and current.
 - Users must be able to add any available attribute as a table column at any time, and must be able to reorder column positions.

-- [x] Extend `CircuitEntry` data model with missing fields from requirements, especially `circuitNumber`, `description`, `deviceType`, `phaseType`, `tradeOrCostGroup`, `group`, `protectionType`, `protectionRatedCurrent`, `protectionCharacteristic`, `cableType`, `cableCrossSection`, `cableLength` and `comment`.
-- [x] Allow multiple entries with the same `circuitNumber` and make this visible/editable in the circuit-list table.
-- [x] Implement project-specific device lists (`ProjectDeviceList`) in backend + UI.
-- [ ] Implement copying devices both directions between global and project-specific device lists.
-- [ ] Add separate device naming model with `Device.name` and `Device.displayName`.
-- [ ] Add explicit entry description field (`CircuitEntry.description`) independent of linked device naming.
-- [ ] Implement device-link lifecycle on entries: link, unlink/detach, and update propagation from device changes to linked entries.
-- [ ] Add `addCount` when adding a device to a circuit list to create multiple entries in one action (`addCount != quantity`).
-- [ ] Relax circuit-entry validation so incomplete entries are possible (currently several fields are required).
-- [ ] Add duplicate-entry action within the same circuit list (separate from copy to another list).
-- [ ] Add sorting/filtering/bulk-edit capabilities for circuit-list tables (beyond current copy-selection flow).
-- [ ] Define and implement fixed selection lists for domain fields (`deviceType`, `phaseType`, `tradeOrCostGroup`, `group`, protection and cable fields).
-- [ ] Extend tests beyond pure power formulas to cover new circuit-entry/device-link behaviors once implemented.
