Battle of the stacks — two stacks' evidence aggregates, side by sideBattle of the stacks

Two stacks, side by side: curated AI stacks or your own product lists. We compare the aggregates the evidence supports — mean PA Score, agent-readiness, arena coverage, verified interconnects, weakest link — and where both sides field one product in the same arena, we link the real judged battle.
