  title: ACMA — spectrum survey by location
  version: 1.0.0
  summary: >-
    From a latitude/longitude, find the nearest licensed transmitter sites, pull the frequency
    assignments in a band and postcode range around them, and attribute an assignment back to its
    licensee.
  description: >-
    The site-selection and interference-check traversal an RF engineer runs before deploying
    equipment in Australia. Every step is an anonymous GET. Note the unit and date conventions:
    assignment frequencies are in Hz, request dates are DD-MM-YYYY, response dates are ISO local
    datetimes. The register records licences, not transmissions — absence here is not proof a band
    is clear.

  summary: Nearest sites to a point, then the assignments and licensee around it.

  steps:
  - stepId: nearest-sites
    description: >-
      Find the closest licensed transmitter sites to the point. This is the only operation that
      computes a distance (DISTANCE_KMS) — always report it rather than implying proximity.

  - stepId: assignments-in-range
    description: >-
      Pull the frequency assignments across a postcode and date range. Omitting the postcode pair
      widens the query nationally and will be silently truncated at 2,000 rows — narrow first.
