  "scope": "Stone and iron axes/picks, rafts and boats weather in all physical storage, with slower rates in packs and storehouses. Loose materials weather only on exposed ground or in ruined storehouses: food 3 days per quality, meals 2, seeds 30, wood 90, planks 120, furniture 240; stone/ore 100 years and brick 200 years. Pack or intact storehouse protection is an abstraction for bulk preservation. Quality multiplies condition. Ruined goods stay in place until clear-ruined removes them. Buildings have 100 condition points times quality and level: wood structures lose 1 point per 3 days; masonry/roads 1 per 12 days. maintain {structure} spends quarter base materials times level (rounded up, matching quality) and at least 15 seconds times level to restore condition without changing authorship. Reserved tools and vessels are cared for during work; spares still weather."
