Cost-model graph (in R)
C10 cost-model graph (in R): a composable C9 graph of cost nodes in aura-std producing net R = gross R - cost-in-R, plus a net_r_equity tap and folding into summarize_r. Per the 2026-06-28 C10 rework (#116, ledger 29cdc8c); supersedes the retired realistic-broker milestone (real friction is not historically knowable). Container for #148 and its cycle sub-issues. A bare gross-R run with no cost model stays valid.
