Pattern Matching Algorithm

# Pattern matching logic (simplified)
def match_crash_pattern(content, location, stack):
    for pattern in KNOWN_PATTERNS:
        # 1. Check location regex
        if not re.match(pattern.location_regex, location):
            continue

        # 2. Check stack pattern match
        matches = 0
        for stack_pattern in pattern.stack_patterns:
            if any(re.search(stack_pattern, frame) for frame in stack):
                matches += 1

        # 3. Require 60% match threshold
        if matches >= len(pattern.stack_patterns) * 0.6:
            return pattern  # MATCH!

    return None  # No match - novel crash
