quantmodel — Extend backtest history: improve data sources; reverse-engineer AS ticker prices/charts and Wayback historic allocations

Objective

Extend backtest history: improve data sources; reverse-engineer AS ticker prices/charts and Wayback historic allocations.

Notes: Shipped hist-alloc/equity-curve/wayback scrapers + extended_history (VFITX→IEF). 60/40 verify 1993+ n=401 corr 0.9985. Findings: extended-history-t100.md

Approach

Reuses existing report research/findings/extended-history-t100.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.

Results

Key table from source report (preserved):

Surface	Depth	Notes
Year×Month returns grid	Full ITD	Already scraped via `strategy_page`
Equity curve Highcharts	Full ITD monthly NAV	Flat array + `pointStart` / `pointIntervalUnit:'month'`
Hist-alloc recent table	~prior 12 months only	AS deliberately withholds older month-end weights
Avg allocation pie	ITD average	Useful universe / weight priors
Avg allocation by year	ITD yearly %	Highcharts column series back to inception
Wayback `/members/...`	0 snapshots	Auth-walled; CDX empty
Wayback public blogs/FAQs	Yes (2016+)	Rules prose / simulated-data footnotes

Conclusions and metrics are in research/findings/extended-history-t100.md; see detail page for preserved tables/metrics.
