/**
 * The cells a cf-harness run is pointed at, before the run exists.
 *
 * An operator deploys this piece, then names two of its cells to a run with
 * `--input-cell secret=<link> --input-cell city=<link>`. The model holds a
 * handle for each and never the value behind it.
 *
 * The pair is the point: `secret` carries a declared confidentiality atom and
 * `city` carries none, so a pattern run over both derives a value the space
 * labels and a value it does not. Reading the two back is what says a
 * per-cell label is a fact about that cell rather than about the run.
