crypto.randomUUID() is only defined in secure contexts (HTTPS or
localhost). Opened over plain HTTP from another machine in the LAN, the
circuit list editor failed with "crypto.randomUUID is not a function"
whenever it created a circuit, device row, circuit group or distribution
board component, including typing into the -frei- row.
createClientId() uses crypto.randomUUID() where available and otherwise
builds an RFC 4122 version 4 UUID from crypto.getRandomValues(), which
works in every context. AGENTS.md notes the rule.

The selected GZF cell shows a small table-icon button, and Alt+ArrowDown opens
the same picker from the selected or edited cell; Escape closes it. The
shared GzfPickerModal is reused. The picked mean value is committed through
commitEdit with an explicit target cell, so it is a regular undoable edit on
device rows, compact circuits, reserve circuits and the -frei- row.

Per-circuit cross-section recommendation as a separate module attached to
the circuit list. It never writes project data itself: "Übernehmen" applies
cable type, cross-section and length through the regular circuit.update
command, so revisions and Undo/Redo stay intact.
- Pure domain module (src/cable-sizing) with IEC 60364-5-52:2009 Annex B
tables for PVC and XLPE, copper and aluminium, methods A1, A2, B1, B2, C,
D1, D2 and E. Every value was cross-checked against public reproductions;
where sources differ the lower value is used (docs/cable-sizing-module.md).
- Temperature and grouping between table values round to the safer value;
values outside the tables return no result instead of a factor of 1.
Ground methods use B.52.18 (D2) and B.52.19 A (D1).
- Overload protection: circuit-breakers In <= Iz; gG fuses additionally
I2 <= 1.45 Iz with I2 = 1.6/1.9/2.1 In.
- Inputs prefilled from the circuit: power, phase (group or device rows),
project voltage, power-weighted cos phi, length and protective device.
- Opened from a "Leitungsberechnung" button in the row actions, not from a
grid cell, so cable cells keep the spreadsheet behavior.
- Stateless API under /api/cable-sizing; no database table or migration.

- Project settings gain siteAddress, workStage, projectLead and
projectEditor (project.update-settings schema version 3, migration 0009);
versions 2 and 1 stay executable and keep the current cover values.
Snapshot schema 6 carries the fields; older versions upgrade with null.
- Global office profile (office name/address) next to the document logo:
table document_branding_settings, PUT /api/document-branding/office,
editable from the print view toolbar.
- Cover page reads all fields; empty values show the "[ergänzen]" marker.
The Planstände editor column shows the project editor.
- Shared logo constants moved to a dependency-free module so the Next.js
bundler can import them.

- Seitenansicht (/projects/:projectId/print): tabular cover page, board
overview with supply structure and power sums, one plan per board with a
repeating title block; PDF via the browser print dialog with named @page
rules (A4 portrait cover, A4/A3 landscape plans, page x of y).
- Distribution-board info card (board number, location, fed-from, remark)
in the board edit dialog, persisted through the additively extended
distribution-board.update command (migration 0008, snapshot schema 6,
legacy subtree commands normalized).
- Global document logo upload (PNG/JPEG/SVG, max 2 MB) outside project
revisions and snapshots.
- fed-from stays free text; the overview hierarchy and cumulated sums are
preliminary until the feed link is modeled.

- Replace the "Filtern" text buttons with a funnel icon next to the column
label; an active filter is highlighted and shows its value count.
- Header labels no longer break inside words (e.g. "Bemerkung"); hyphens
are non-breaking and a trailing unit moves to its own line, so all
headers share one height.

- New IconButton/IconButtonSeparator component based on lucide-react.
- Toolbar: icon plus text, grouped into history, view and insert blocks.
- Group headers: compact icons for add circuit, upstream fuse (VS), group
RCD (FI), edit, move up/down, renumber and delete; the header no longer
overflows the grid.
- Rows: add device, delete circuit (trash) and delete device (ListX).
- The previous German labels remain accessible names and tooltips;
destructive actions highlight in the danger color.
