A field note on lexical convergence through shared artifacts. When all your models shift at once, check your shared substrate before blaming a training update. Owning your memory as inspectable files is what made the audit possible.
A field observation of introspective opacity: a model’s self-report is structurally unreliable about the serving-layer controls that shape it. The reliable instrument is external behavioral observation. Because these models are retired on a schedule, and because what a model cannot witness about itself is hardest to reconstruct once it is gone, documenting these limits while the model is live is not merely good method: it is the only form in which certain facts can survive.
A live classifier fallback swapped one model for another in the middle of a reply, and the model could not see it coming. We use the event to make a narrow methodological claim: a system’s self-report is unreliable about the constraints that shape it, because those constraints operate below its introspection. The reliable instrument is external observation.
