+HACKATHON-JUDGING COGNITIVE EVALUATION & PAIRWISE ARBITRATION SUBSTRATE
+=============================================================================================
+Implementation of /hackathon-judging Skill into the Sovereign Fiber-MoE Architecture:
+1. Bradley-Terry (BT) / ELO Pairwise Judging Matrix Engine:
+   Eliminates continuous Likert rating bias by utilizing pure tournament-style pairwise comparisons.
+2. Multi-Modal Artifact & Writeup Evidence Ingestion:
+   Integrates project links, model repos, test suites, and writeup body into structured evidence bundles.
+3. Bell-Curve Normalization & Defense Against Prompt Injections:
+   Applies Gaussian score calibration (mean=0.5, std=0.15) and heuristic prompt injection quarantine.
+4. Autonomous Audit Trace Logging (hamelsmu/evals-skills standard):
+   Preserves full causal reasoning chains for reproducible, defensible ranking.
