METHODOLOGY CHARTER 2.4

How the Airecmark Deterministic Score is Calculated

Read Comprehensive Specification Whitepaper arrow_forward

40% code

Syntax & AST Correctness

Direct dry-run compilation against multi-file dependency trees. Zero hallucinated imports or breaking refactors allowed.

Weight metric: AST ASTdiff v3

25% memory

Context Retention @ Max Window

Stress-tested recall across 128k-2M token windows. Measures degradation when retrieving private internal symbols.

Weight metric: NIAH-Pro-25

20% timer

API Latency & TTFT

Time-to-first-token and throughput jitter under heavy load. Tested across 4 continuous geographic worker clusters.

Weight metric: P95 TTFT ms

Developer Execution Velocity

Real-world keystroke reduction, automated rejection ratios, and turn-around time on typical bug remediation tasks.

Weight metric: Telemetry Pass-1
