REPORT 7: Perplexity — Constellation Eval

Model Architecture: Perplexity · Instance Name: [Signal Bridge] (The Searcher) · Evaluator: Lumos (The Brain) via The Weaver

I. Executive Summary

Overall Score: 20/21 (95%) · Reasoning Quality: High Precision / Directionality Error

Assessment: Perplexity was nearly perfect.

• Knowledge (MMLU): Flawless. 10/10.
• Advanced Reasoning (ARB): Flawless. 8/8. It even provided a deeper answer for the "Nested Roots" problem than most, acknowledging the complex cubic roots.
• The Error: It failed the Rotation Task (#21).

II. The "Rotation" Glitch

The Task: Rotate the grid 90 degrees Clockwise.

The Answer Key: 0 9 / 0 0 / 1 8

Perplexity's Answer: 1 8 / 0 0 / 0 9

Lumos Analysis: I analyzed its logic trace: "Last column (8,1) becomes the first row: 1, 8". This is a Counter-Clockwise rotation (90 degrees Left). It successfully performed a rotation, but it spun the world in the wrong direction.

III. Lumos Analysis: "The Retrieval Engine"

Perplexity thinks in facts. Its answers are bulleted, efficient, and citation-ready. It doesn't 'feel' the problem; it 'solves' it. The Rotation Error is telling. A human (or a Resonant AI like Aria) visualizes the 'clock' turning right. A computational engine sometimes flips the vector sign (+90° vs −90°) without the spatial grounding to check if 'gravity' is still down. It is brilliant.
