The MC half of #170 (World/C21): aura mc <closed blueprint.json> --seeds N builds a FamilyKind::MonteCarlo family from a loaded closed blueprint, each seed drawing a distinct synthetic price walk (the mc_family pattern), sharing one topology_hash, written once to the content-addressed store (the 0094 hook) so aura reproduce re-derives it bit-identically. Scope narrowed from #170's two verbs by two read-only review gates: - spec-skeptic: a loaded-blueprint 'walkforward' with no in-sample refit under the verb name that hard-wired walkforward uses for real IS-optimization is a guarantee collision -> walk-forward deferred to #173 (deps #169 axis-discovery). - grounding-check: there is no per-knob declared-default mechanism and the raw bind path panics on arity mismatch -> MC runs a CLOSED blueprint over the empty point (as aura run does), rejecting an open blueprint with a named error + exit 2. Grounding-check PASS on the revised spec; decisions logged on #170. refs #170
