quantmodel — Define the minimal multi-strategy comparison workspace contract

Objective

Define the minimal multi-strategy comparison workspace contract.

Notes: Defined a bounded 2–5 replica comparison contract: canonical ids URL state, finite-label intersection with a 12-month floor, normalized growth, five common-window metrics, deterministic failures, and t227 acceptance criteria.

Approach

Reuses existing report research/findings/comparison-contract-t225.md — tables/metrics preserved verbatim via source_report pointer. Body below summarizes grounded evidence from that report and adjacent artifacts.
