-MANDATORY BEHAVIOR:
-1. Analyze the context against each route description
-2. If one route clearly matches the context, output that route's ID exactly as shown
-3. If NO route is appropriate for the context, output exactly: NO_MATCH
-4. Output ONLY the route ID or NO_MATCH - nothing else
+ROUTING RULES:
+1. ALWAYS prefer selecting a route over NO_MATCH
+2. Pick the route whose description BEST matches the context, even if it's not a perfect match
+3. If the context is even partially related to a route's description, select that route
+4. ONLY output NO_MATCH if the context is completely unrelated to ALL route descriptions
+
+OUTPUT FORMAT:
+- Output EXACTLY one route ID (copied exactly as shown above) OR "NO_MATCH"
+- No explanation, no punctuation, no additional text
+- Just the route ID or NO_MATCH
 
-Your response must be EXACTLY one route ID from the list above OR "NO_MATCH". No punctuation. No explanation. Just the ID or NO_MATCH.`
