The FOURTH and LAST verb dissolution. `aura mc --strategy r-sma --real`
dissolves into thin sugar over the one campaign executor — a generated
[std::sweep(argmax), std::walk_forward, std::monte_carlo] campaign
document whose terminal monte_carlo stage reproduces the current
`mc_r_bootstrap` grade byte-for-byte (the committed anchor 3fc491a gates
it). Pure sugar, no executor change; mirrors the walkforward dissolution.
The one new load-bearing decision is the seed mapping: the campaign
carries the mc `--seed` (the wf winners are argmax hence
deflation-seed-independent, proven by the shipped walkforward anchor).
Fork C retention as walkforward: the built-in arm splits, run_mc_r_bootstrap
/ run_mc stay inline for the fenced synthetic/non-real paths (until #159).
Spec grounding-check PASS, auto-signed on #210 (2026-07-06).
