Step 1: Understanding the Concept
The query seeks to identify an architectural treatise that prominently highlights the adverse effects (`doshas`) of construction flaws on the patron and the realm.
Step 2: Analyzing the Texts
While significant Vastu texts such as Mayamata and Mānasāra address the importance of sound construction and the negative impacts of defects, the Samarāngaṇasūtradhāra, authored by King Bhoja, is particularly recognized for its comprehensive and detailed exploration of this topic. It extensively details how architectural deficiencies in structures (residences, palaces) or urban planning can precipitate specific calamities, illnesses, financial losses, and even the collapse of the ruler and his kingdom. The text dedicates substantial sections to this diagnostic dimension of Vastu, making it a defining characteristic.
Step 3: Final Answer
The Samarāngaṇasūtradhāra is the treatise most distinguished for dedicating entire chapters to the misfortunes stemming from architectural imperfections.
