[vntrevx]

Summary

• connect typed Rust vector output directly to the chronological simulator
• run independent pair vector DAG preparation in parallel while preserving pair order and single-threaded wallet mutation
• retain SHA-verified Feather replay and prove direct/Feather trade-surface plus every-candle full-state exactness
• record bounded diagnostic transport evidence without claiming latest-X7 Full Native qualification

Validation

• uv run pytest -q (804 passed)
• future-NFI compatibility profile (143 passed)
• cargo test --workspace --locked (224 default tests passed; 1 explicit diagnostic ignored)
• cargo clippy --workspace --all-targets --locked -- -D warnings
• Spot and Futures full fixture parity: trades exact, state exact

Claim boundary

M21-04 only. M22-01 still owns remaining latest-X7 lowering and independent latest Spot/Futures Full Native qualification.
