- Counts describe imported records, not an assertion every election or county is covered.
- Alaska reports by election district; no unsupported county allocation is made.
- County and district boundaries change over time; 2017 map geometry is a reference.
- Unopposed races with no recorded vote totals remain distinct from missing sources.
- 2026 records are dated provisional snapshots; no certified outcome or race call is inferred.

Raw snapshots are preserved. Runtime overlap resolution is explicit: curated baseline state/district records have priority 95; supplemental priorities appear in `src/coverage-sources.js`. Known baseline defects receive review holds. Higher-priority sources replace a matching geographic contest in the displayed view and retain alternate source references; raw files are unchanged.
