  CycleCalcs publishes its controlled vocabulary as a live API endpoint —
  GET /v2/enums returns every enumerated value the API can emit or accept,
  each set scoped to the endpoints that use it. 40 sets in all,
  covering the body list, moon-phase names (northern and southern emoji
  variants), rise/set statuses, event kinds, zodiac signs, compass points,
  visibility phrases, the 74 warning codes, the 117 error codes, formats,
  frames, cache classes, rights states, the 21 tracked astronomical cycles
  and the explicit non-goals. Captured verbatim to
  vocabulary/cyclecalcs-enums.json.

notes:
  frame_identifiers: >-
    The frame IDENTIFIERS eqj, eqd, ect, ecl, hor and gal are defined at /v2/conventions under frames. They are not accepted values of the frames parameter, which takes the frames_parameter set.
  rise_set_special: >-
    rise_set.special is nullable: the two codes in the rise_set_special set are the only non-null values, and null means neither polar condition applies.
  known_unreachable: >-
    On warning_codes and error_codes, known_unreachable true means this version cannot produce the code and names the surface it belongs to. False means it is not known to be unreachable, which is weaker than a promise that you can reach it.
  hemisphere: >-
    The hemisphere parameter selects the phase EMOJI only. It does not affect limb orientation: that comes from bright_limb.orientation_angle_deg, which is derived from the observer position and is already correct in either hemisphere.

  description: >-
    A companion controlled register: every dataset behind every endpoint with
    its holder, version, role, licence, credit line and the obligation it puts
    on a caller. Records both `licence` and `license` spellings deliberately,
    because spec-00 fixes meta.engine.license while the GeoNames register
    entry is specified with `licence`.
withheld:
  - set: meteor_showers
    reason: Withheld pending a licence review (stated on /api.html).
  - field: saros_member_number
    endpoint: /v2/eclipses
    reason: Withheld pending a licence review; the series number is published.
