  "role": "resource-collector",
  "name": "The Last Measure",
  "function": "A civic excavation works extracts building limestone and cuts new burial capacity, measuring each load against the shrinking bedrock that must support the city.",
  "shape_and_silhouette": "Four inward-leaning stone buttresses carry a low iron winding crown above a sealed shaft collar, flanked by a long low vault and a descending sequence of stone sorting bays.",
  "visual_description": "Chalk-dusted brick vaults and scarred limestone supports surround a black iron extraction throat, with suspended lifting chains, graded blocks and an oversized vertical depth gauge making the remaining ground feel countable.",
  "production_notes": "This working-district resource collector occupies a level service yard over a licensed excavation shaft and uses durable repairable industrial masonry.",
  "departure": "Its squat converging supports resemble a hand holding a hole shut, and a prominent survey gauge turns finite burial capacity into a visible civic countdown.",
  "shared_traits": [
    "Excavation stone reused as building material",
    "Brick vaults on limestone piers",
    "Replaceable metal screens and survey marks"
  ],
  "constraints": [
    "Shaft remains closed with overlapping metal extraction shutters",
    "No exposed remains, underground cutaway or timber equipment",
    "All four inclined supports meet a braced square iron headframe"
  ],
  "idle_animation": "The hoist chain inches upward and its small suspended empty iron cradle makes a restrained settling movement.",
  "day_night": "Shielded amber work lamps light the gauge and loading bays while the closed shaft collar stays almost black.",
