summary: >-
  There is no sandbox in the test-environment sense — no test mode, no test credentials, no fixture
  data, no separate host. What H&P does publish is an interactive console and two free browser
  calculators that hit the SAME production calculation the API exposes. Because the API is
  anonymous, read-only and side-effect-free, the production endpoint IS effectively the try-it
  surface, which is why a console is meaningful here where a test mode would be meaningless.
test_mode:
  exists: false
  key_prefixes: []
  note: No test-vs-live distinction exists; there are no keys at all.
test_data:
  published: true
  form: spec-embedded worked defaults
  note: >-
    Every one of the 19 required parameters carries a real worked default value in the contract —
    latitude 29.4217, longitude -98.4838, depthBelowMSL -200, measuredBTotal 46475.6, measuredDip
    57.96, measuredGTotal 9.803, referenceBTotal 46644.9, referenceDip 58.04, referenceGTotal 9.8,
    referenceDeclination 4.24, surveyDate 2017-10-12T11:00:00.000-0600, toolCode MWD, wellbore
    inclination/azimuth 45/45, antiCollisionSigma 2.0. A caller can execute a complete, valid,
    meaningful request straight from the spec without inventing a single value. These are the
    provider's own published values, captured verbatim — not invented here.

    note: >-
      Survey recovery scenario simulator. Browser-only; no API of its own was found (no spec
      document, no XHR contract published).
gaps:
  - No test environment, test tenant or seeded fixture data.
  - No time simulation or trigger tooling (not applicable to a stateless calculation).
  - The console executes real production calls under the Survey Validation API EULA.
