recommendedCrossSection now satisfies two criteria and takes whichever
demands more copper: the voltage-drop budget, and an ampacity at least
as high as the fuse protecting the circuit (ABYC E-11: the OCP rating
must not exceed the conductor's ampacity). Ampacity comes from ABYC
E-11 Table 6A for AWG and ISO 13297 Table A1 for mm², both 105 °C.
Before this, a 40 A load over 0.5 m was sized 1.5 mm² / AWG 16 next to
a 50 A fuse: a cable the fuse can never protect. Long runs stay
voltage-drop driven and unchanged.
The drop budget is now stored per system (3 / 5 / 10 %) and editable in
the system editor, with a global default in Settings that the
standalone calculator uses and new systems inherit.
Cross-sections are derived, never entered by the user, so LoadCableSync
re-derives them when a system opens and when its budget changes.
Library loads are computed instead of being stored as a 1.0 mm²
placeholder. LoadConfigurationStatus therefore reports only what the
user can actually fix: missing length or current.
Also removes the dead cable.pro.* strings and folds three copies of the
mm²-to-AWG conversion into ElectricalCalculations.nearestAWG.
QLPreviewController only renders its share, print and open-in actions
when it is inside a navigation controller, so diagram and report
previews were dead ends. Wrap it in one, add an explicit Done button
and assert both in a UI test.
The Overview share menu offered a wiring diagram and a full report even
for an empty system. Gate it on loads, batteries or chargers being
present (iOS + Android) and add UI tests for both states.
Replace preview-based screenshot rendering with simulator XCUITests
driven by shooter.sh (per-language locale + status bar overrides,
xcparse extraction). Add batteries-list accessibility identifier and
update CLAUDE.md screenshot docs.
