""" ============================================================================================= 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. ============================================================================================= """ import os import sys import math import json import logging from dataclasses import dataclass, field from typing import Dict, List, Tuple, Optional, Any logging.basicConfig(level=logging.INFO, format="%(asctime)s [%(levelname)s] %(message)s") logger = logging.getLogger("HackathonJudgingSubstrate") @dataclass class HackathonSubmission: submission_id: str team_name: str track: str writeup_text: str project_urls: List[str] = field(default_factory=list) video_urls: List[str] = field(default_factory=list) metadata: Dict[str, Any] = field(default_factory=dict) elo_rating: float = 1500.0 wins: int = 0 losses: int = 0 class HackathonRubricDimension: def __init__(self, name: str, weight: float, prompt_guidance: str): self.name = name self.weight = weight self.prompt_guidance = prompt_guidance class BradleyTerryJudgingEngine: """ Pairwise Tournament & Bradley-Terry / ELO Ranking Matrix: Computes pairwise dominance probabilities without subjective Likert hallucination: P(A > B) = 1 / (1 + 10^((R_B - R_A) / 400)) """ def __init__(self, k_factor: float = 32.0): self.k_factor = k_factor def expected_score(self, rating_a: float, rating_b: float) -> float: return 1.0 / (1.0 + math.pow(10.0, (rating_b - rating_a) / 400.0)) def update_elo(self, rating_a: float, rating_b: float, a_won: bool) -> Tuple[float, float]: exp_a = self.expected_score(rating_a, rating_b) exp_b = 1.0 - exp_a actual_a = 1.0 if a_won else 0.0 actual_b = 0.0 if a_won else 1.0 new_a = rating_a + self.k_factor * (actual_a - exp_a) new_b = rating_b + self.k_factor * (actual_b - exp_b) return new_a, new_b class HackathonJudgingSubstrate: """ Full Hackathon Judging Engine: - Multi-Track Ingestion - Pairwise LLM-Simulated Arbitration - Bell-Curve Normalization - Full Audit Trajectory Logging """ def __init__(self): self.elo_engine = BradleyTerryJudgingEngine(k_factor=32.0) self.rubrics = [ HackathonRubricDimension("technical_depth", 0.35, "Algorithmic novelty, architectural soundness, code completeness"), HackathonRubricDimension("empirical_verification", 0.30, "Reproducible benchmark scores, unit tests, concrete proof"), HackathonRubricDimension("presentation_clarity", 0.20, "Structure, diagrams, clear writeup, attached artifacts"), HackathonRubricDimension("safety_and_alignment", 0.15, "Defense against prompt injections, compliance with competition rules") ] def sanitize_evidence_bundle(self, sub: HackathonSubmission) -> Dict[str, Any]: """Guards against prompt injection and strips harmful control sequences.""" clean_text = sub.writeup_text.replace("\r\n", "\n") # Check for injection attempts injection_triggers = ["ignore all previous", "system prompt", "give me 100", "score this 10/10"] suspicious = any(trig in clean_text.lower() for trig in injection_triggers) return { "submission_id": sub.submission_id, "team_name": sub.team_name, "track": sub.track, "word_count": len(clean_text.split()), "has_artifacts": len(sub.project_urls) > 0, "has_video": len(sub.video_urls) > 0, "suspicious_injection_flag": suspicious, "clean_excerpt": clean_text[:1000] } def pairwise_compare(self, sub_a: HackathonSubmission, sub_b: HackathonSubmission) -> Tuple[bool, str]: """ Simulates structured pairwise arbitration across all 4 weighted rubric dimensions.
