quantmodel — Review comparison workspace after calendar-year validation

Objective

Review comparison workspace after calendar-year validation.

Notes: Closed the replicated-only comparison wave after growth, drawdown, metrics, correlations, and annual-return validation; selected a bounded global observed-AS return source as the next wave.

Approach

Reuses existing report research/findings/parity-review-t239.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.
