The residual-cost notes stayed inside the lattice-active profiles. They were short. They were factual. They attached only to flags that knowingly risked additional residual load on near-tolerance residual-exposure bodies.
Dual-logging did not require them. Most of the time the notes traveled with the flag and were never read by secondary architecture.
Then one note was pulled into a dual-log because the flag moved a public stability window. Callen's staff saw it.
The language was plain: residual-cost projected for near-tolerance residual-exposure bodies in corridor X; intervention still recommended to prevent cascade. No apology. No request for permission. Just the accounting the operators now refused to omit.
Secondary architecture treated the note as unsolicited risk language that had no place in metric-facing residual insight.
