  "id": "04-monumental",
  "role": "monumental",
  "name": "The Ear of the Abyss",
  "function": "A civic listening monument gathers distant whale song and shelters memorial chambers in two pressure-sealed foundation pods.",
  "shape_and_silhouette": "A tall upright octagonal shell frame stands on two squat trapezoidal piers, with three stepped concentric rims surrounding a large empty aperture and one small listening lens centered beneath it.",
  "visual_description": "Broad ivory mineral panels meet at bronze corner clamps, while recessed cyan light strips, small flush memorial portholes and a basal glass lens keep the monument quiet and distinctly abyssal.",
  "production_notes": "A later civic commission assembled from cultivated mineral segments around an engineered bronze frame, with constant-depth extrusions, straight beams and simple pressure pods suited to procedural construction.",
  "departure": "Replace the leaning sculpted ear and twisting ribs with a monumental faceted listening frame whose empty center remains its defining feature.",
  "shared_traits": [
    "Cultivated barnacle-white mineral shell panels",
    "Bronze pressure collars and exposed joints",
    "Small recessed cyan lights"
  ],
  "constraints": [
    "One upright elongated octagonal aperture, completely open",
    "Three constant-depth nested octagonal rims, no twisting surfaces or spirals",
    "Two flat-bottomed trapezoidal support piers",
    "Exactly one small basal listening lens, diameter at most one eighth of total monument height",
    "Six flush memorial portholes, diameter at most one fortieth of total monument height",
    "Light strips inset into the rim; no floating bulbs, emissive spheres or membrane",
    "Memorial chambers occupy two sealed foundation pods, not the narrow frame",
    "No backward lean or sculpted anatomical curl"
  ],
  "idle_animation": "A subtle cyan pulse moves between eight fixed recessed inner-rim light strips; all geometry remains stationary.",
  "day_night": "Communal remembrance cycles gently brighten the six small flush memorial lenses, with no simulated daylight.",
  "version": 2,
  "approved": false,
  "revision": "Preserve the name, listening and memorial purpose, open center, ivory and bronze palette, basal glass lens and paired supports; replace the leaning oval, twisting curl and swollen lights with a vertical faceted frame and tightly bounded details.",
