// Investor Flow — Confluence Slot Catalog (M22, slice 2)
//
// The 40-slot confluence inventory for the Confluence Signal Engine. Each slot is
// a named, independently-evaluable check whose *firing* state contributes bullish
// or bearish evidence about a symbol's entry/exit quality.
//
// Pure data + retrieval helpers: NO I/O. ADR-0007: slots describe "quality of the
// picture" — never a buy/sell recommendation. Each slot has an ADR-safe explain
// note phrased as evidence ("relative strength is in the upper decile") rather
// than a directive ("buy").

 * existing position rather than a fresh short thesis. Exit slots are still counted
 * as bear evidence (risk-off side of the picture).
