Function aggregate 

pub fn aggregate(
    panel: &Panel,
    reported: &[Option<ReviewerReport>],
) -> PanelOutcome

Derives a panel’s verdict from its reviewers’ reports.

This is the whole aggregation, and it is deliberately dull: Pass iff at least quorum seats reported Pass. Confidence is carried through as evidence and never consulted; there is no veto and no weighting, so a panel behaves the same way every time and an operator can predict it from the config alone.

reported is indexed by reviewer; a None — or a short slice, which is what a stage abandoned part-way through its panel leaves — fills that seat with ReviewerReport::silent. Nothing here reads a clock, a process, or the store, so the aggregate is derived at read time rather than stored: a resumed run recomputes the identical verdict from the identical rows.
