Function view_from_block 

fn view_from_block(
    store: &Store,
    meta: &HashMap<String, Value>,
    ctx: &ExportContext,
    warnings: &mut Vec<String>,
) -> LayoutView

One pane tab, written from the per-type allowlist (spec §3.3). Anything not named here — session ids, instance ids, env, runtime state, CLI paths, failure records — is never written. An unknown view type is written as {type} alone.
