Milestone-close gate for "Cost-model graph (in R)" (#148). The fieldtester exercised the milestone capability end-to-end from the public CLI only (no implementation source), on the stage1-r harness, against ledger C10 + the glossary. Roll-up: friction_found — 0 capability bugs; the milestone promise is empirically delivered: - bare gross-R run is clean (net == gross, no cost forced); - per-trade cost: gross pinned, net drops strictly/monotonically, net_r_equity tap persists; - the capstone per-held-cycle carry BLEEDS the net-R curve continuously over a hold (the gross-net gap grows 0.367 -> 0.734 -> 1.101 -> 1.468 across one hold, vs the per-trade run's flat 0.367) — the holding-cost shape change, observable end-to-end; - composition is exact-additive (the composed drag equals the sum of the single-cost drags to the last ULP) and `aura chart` renders the real net_r_equity series. Evidence under fieldtests/milestone-cost-model-graph/ (run_scenarios.sh + captured_outputs.txt + traces/ + the charted bleed + FINDINGS.md). Non-blocking findings filed forward (none gates the close): - cost-flag CLI ergonomics — units hint, negative-rate diagnostic, non-R-harness no-op + a C10 spec_gap -> #153; - docs/project-layout.md describes the retired `aura backtest --broker` path and omits the cost flags -> folded into #151. refs #148
