geolocation.latitude: precondition -90 <= LATITUDE <= 90…

Error message

geolocation.latitude: precondition -90 <= LATITUDE <= 90 failed.

What it means

`verifyGeolocation` enforces latitude within [-90, 90]. Out-of-range values throw with this precondition-style message.

Solutions

1. Clamp latitude to [-90, 90] before passing
2. Double-check that latitude and longitude aren't swapped
3. Validate input ranges before calling setGeolocation

Example fix

// before
await context.setGeolocation({ longitude: 0, latitude: 120 });

// after
await context.setGeolocation({ longitude: 0, latitude: Math.max(-90, Math.min(90, 120)) });

function validateLat(lat: number): number {
  if (lat < -90 || lat > 90) throw new Error(`latitude out of range: ${lat}`);
  return lat;
}
await context.setGeolocation({ longitude: lon, latitude: validateLat(lat) });

When it happens

Trigger: `context.setGeolocation({ longitude: 0, latitude: 95 })` or `newContext({ geolocation: { latitude: -120 } })`.

Common situations: Sign/typo errors in coordinates; unverified data from external sources; latitude/longitude swapped (longitude values can exceed ±90).
