## Changelog

### 0.1.7 — 2026-11-01

- **Verification run:** fetched a fresh live **worldwide** snapshot of **500 unique aircraft** in ~134 s with **0% duplicates** (deduplicated by `icao24`). Core/identity fields are rich: `icao24` 100%, `originCountry` 100%, `source` 100%, `latitude`/`longitude` 99.6%, `onGround` 100%, `callsign` 98.6% (a few aircraft broadcast no callsign — expected).
- **Confirmed data-dependent fields behave correctly:** `baroAltitudeM`/`geoAltitudeM`/`verticalRateMs` ~88% (null only for on-ground aircraft — 56 of 57 ground aircraft had no altitude), `squawk` 61% (not every transponder broadcasts it). The mode-specific fields (`matchedQuery` in flight mode; `departureAirport`/`arrivalAirport`/`firstSeen`/`lastSeen` in airport mode) are intentionally null for region snapshots.
- **No value bugs:** verified no `[object Object]`, correct numeric/boolean types, 31 distinct origin countries, all positions sourced from ADS-B.
- **README refreshed** to the gold standard: output example and field reference regrounded against the fresh run, clearer pagination/scale and FAQ sections, and up-to-date numbers.
- No input/output field changes — fully backward compatible.
