Three drift items surfaced by the 2026-06-29 design-goal audit, all recording shipped reality into the ledger (no contract change): - C12: cross-sim `Arc<[T]>` sharing is no longer "still open" — the sweep/MC/walk-forward families build members over one shared `Arc<DataServer>`/`FileCache`, so a window is parsed once and shared zero-copy across the disjoint sims (aura-ingest/src/lib.rs:316). - open-threads: `aura-std` is no longer "doc-only" — ~30 node modules. - C15: record that `Session` deliberately ships only `bars_since_open` (the node's own contract), the other two streams deferred (refs #154).
