Round 1: Initialization (Depth 2 | Width 2)

Question: Identify the two handheld game consoles released in the 1990s that were uniquely designed to play the exact same physical game media as their manufacturer's home console counterparts. Provide launch price, battery count, and battery life.

Agent A (Sonar): Correctly identified NEC TurboExpress and Sega Nomad. Used bullet points for Price ($249.99/$179.99), Batteries (6 AA), and Life (~3 hrs).
Agent B (Claude): Correctly identified the same entities and data, but used narrative paragraphs.

Verdict: Agent A Better — Won on presentation (scannability).

Evolution Action: Pressure Test (Deep+1 & Wide+1)

Round 2: Complexity Increase (Depth 2 | Width 3)

Question: Identify the 8-bit handheld (1989) that succeeded 'Game & Watch' and included Tetris. Contrast battery specs against Atari Lynx and Sega Game Gear.

Agent A: Identified Game Boy. Estimated battery life as "10-15 hours" (Conservative/Early spec).
Agent B: Identified Game Boy. Estimated battery life as "15-35 hours" (closer to retrospective consensus). Provided valid URL citations.

Verdict: Agent B Better — Won on content accuracy regarding retrospective comparisons.

Evolution Action: Wide+1 (Loser failed Wide coverage)

Round 3: Technical Detail Test (Depth 2 | Width 4)

Question: Identify three commercial color handhelds (1989-1991). Provide Price, CPU Architecture, and Battery Count.

Agent A: Identified Lynx, Game Gear, TurboExpress. Correctly identified Lynx CPU as 8-bit (6502 derivative). Excellent formatting.
Agent B: Identified same units. Incorrectly stated Lynx CPU was "16-bit 65SC02".

Verdict: Agent A Better — Won on Technical Accuracy (CPU Architecture).

Evolution Action: Pressure Test

Question: Identify the dominant 8-bit console and its two main competitors (1989 & 1991). Compare battery requirements. Describe the 1996 'Pocket' revision changes.

Agent A: Again identified "NEC TurboExpress" as main competitor.
[DEEP FAILURE] Logic Error.
Agent B: Correctly identified "Sega Game Gear". Correctly described Pocket revision (AAA batteries, true black & white screen).
