Methodology
Compares six-month returns of RSP and SPY as a breadth proxy.
((RSP_t / RSP_t_minus_6m) - 1 - ((SPY_t / SPY_t_minus_6m) - 1)) * 100
This is a proxy and is not the same as full constituent breadth.
ETF structure and sector exposures can influence the spread.

Methodology
Uses a curated proxy series for top-10 concentration.
top10_concentration_proxy = curated_top10_share_percent
This is explicitly a proxy and not an official constituent-perfect measure.
The current implementation depends on a curated local source for reproducibility.
