quantmodel — Broaden download_history_with_proxies across IPO-truncated runners (beyond ad-hoc DBC helpers)

Objective

Broaden download_history_with_proxies across IPO-truncated runners (beyond ad-hoc DBC helpers).

Notes: Shared download_universe_with_proxies; _run auto-stitches; VNQI←RWX; HAA/GTAA/Carlson panel 2014-11→2013-01. Findings: proxy-stitching-t124.md

Approach

Reuses existing report research/findings/proxy-stitching-t124.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.
