WAZ/DXCC award rings are stored with the closing edge implicit (the renderer
close()s single-segment rings). Rings that straddle ±180° are split into
multiple segments, and multi-segment rings must not be close()d (each close()
would draw a spurious chord across the map), so the implicit closing edge
was never drawn -> the shared boundary between WAZ zones 31/32 (165E,-8 ->
180,-12), and the closing edges of Russia's main ring / Fiji / Russia's
Chukotka tip in DXCC, stayed open.
Fix: store every ring explicitly closed (append first point). splitRingAt
Antimeridian then cuts the closing edge at ±180 exactly like any other edge,
so each segment ends on the correct side and the boundary lines render.
- Zangnan (Arunachal Pradesh): China ring south edge moved from the de-facto
line to the official claim (DataV Tibet south arc); India ring's Arunachal
protrusion removed so the region shows as China (both rings share the new
boundary). Verified: Zangnan points in China ring only, Assam stays India.
- Karakoram corridor / Shaksgam valley (China-controlled since 1963): the
coarse 13-pt west segment (Karakoram Pass -> Afghan/Tajik corner) replaced
with the official Xinjiang south arc (232 pts) — the valley is now inside
the China ring. Aksai Chin was already correct; no other entity deviates
from the official map (SCS islands follow their own DXCC entities).
- wapc/dxcc assets: add Hong Kong & Macau labels (forceLabel) and MO boundary in dxcc
- AwardBoundaryOverlay: rings split at antimeridian no longer close() per segment — removes spurious Russia cross-continent chord
- AwardCalculator: Macau DXCC entity 330 -> 152 (+test)
- Settings LoTW dialog: add sync duration hint (zh/en)
- Grid-mode top bar replaced with award filter chips (All/DXCC/VUCC/
WAPC/WAJA/WAZ/WAS) showing live progress (count/target)
- New AwardBoundaryOverlay renders real administrative boundaries
(provinces/prefectures/CQ zones/states/countries) with the VUCC visual
language: yellow boundary lines, green fill for worked regions, labels
- Boundary assets packaged from public GeoJSON (DataV China, Japan land,
HB9HIL CQ zones, Natural Earth states/countries) with ADIF match keys:
WAPC province codes, WAJA ADIF prefecture numbers, US state abbrs,
ARRL DXCC entity codes
- GridQso extended with dxcc/country/cqz/state parsed from LoTW report
(qso_qsldetail); AwardCalculator derives six-award progress; STATE is
interpreted per DXCC entity (ADIF 'STATE depends on DXCC')
- Grid-mode toggle pill floated at map top-right (Grid mode / Satellite mode)
- New tests: AwardCalculatorTest (9 cases), LoTW award-field parsing (3 cases)
