Method row_count

nodedb-array/src/tile/sparse_tile.rs:173–175

Total physical row count including sentinel (Tombstone / GdprErased) rows. Use this as the upper bound when iterating over rows; check [`row_kind`](Self::row_kind) inside the loop and skip non-Live rows when reading attribute columns. The attribute column vectors are indexed by the **live-row index** (incremented only for Live rows), not by the iteration index — confusing the two yields incorrect

    /// not by the iteration index — confusing the two yields incorrect or
    /// out-of-bounds reads.
    pub fn row_count(&self) -> usize {
        self.surrogates.len()
