quantmodel — Split strategy alloc charts: yearly avg + monthly past year (AS first, shared colors)

Objective

Split strategy alloc charts: yearly avg + monthly past year (AS first, shared colors).

Notes: Split alloc UI: yearly ITD + monthly past-year (88/102 have monthly). AS left / Ours right; shared ticker colors. Export fields alloc_yearly_ + alloc_monthly_. ensure-as-bulk 102/102; export reuse_ours 102/102. Findings: alloc-compare-split-t169.md.

Approach

Reuses existing report research/findings/alloc-compare-split-t169.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):

Panel	Canvas	When shown
Average yearly allocations	`#chart-alloc-yearly`	Always when yearly AS (or ours) exists
Monthly allocations (past year)	`#chart-alloc-monthly`	Only when AS has recent ~12m month-ends
Legacy single chart	`#chart-alloc`	Hidden fallback for pre-split payloads

Conclusions and metrics are in research/findings/alloc-compare-split-t169.md; see detail page for preserved tables/metrics.

Conclusions

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