Exhaustively investigate reliable AAII asset-allocation history sources

Objective

Exhaustively investigate reliable AAII asset-allocation history sources.

Notes: Found AAII's public first-party asset.xls via its survey page; recorded SHA-256/HTTP provenance, 1987-2026 coverage, licensing boundary, alternate-source rejections, and an explicit repair requirement for 22 malformed 2006-07 cached date cells. Acquisition is unblocked for internal derived research without raw redistribution.

Approach

[reconstructed — uncertain] No dedicated findings Markdown located for t337. Summary reconstructed from research/findings/task-history.json entry and git history. Uncertain fields: detailed approach, exact file list, and metrics beyond the task note.

Files / code / data changed

• No commit SHA confidently associated with t337 in sampled log [reconstructed — uncertain].
• Task-history entry: research/findings/task-history.json#t337

Results

Task note: Found AAII's public first-party asset.xls via its survey page; recorded SHA-256/HTTP provenance, 1987-2026 coverage, licensing boundary, alternate-source rejections, and an explicit repair requirement for 22 malformed 2006-07 cached date cells. Acquisition is unblocked for internal derived research without raw redistribution. [reconstructed — uncertain] No quantitative tables recovered for this entry; see git diff and task-history for grounds.

Conclusions

[reconstructed — uncertain] Outcome inferred from status done and task note.
