Report #103327

[synthesis] Same prompt and parameters produce different quality after a model update because aliases silently point to a new version

Pin model snapshots, not aliases, in production configs; run regression suites across model versions before deployment; maintain a golden prompt set with expected behavior and acceptable variance.

Journey Context:
Providers update model aliases in place, so 'gpt-4' today is not 'gpt-4' six months ago. OpenAI's deprecation docs make this explicit, but teams often discover drift only through user complaints. Snapshot pinning plus regression testing turns silent upgrades into detectable, reviewable changes.
