The previous commit's test and README described a freshly bootstrapped
machine as lacking converged_* and rendering 'not recorded'. That pins the
wrong contract: #61 states plainly that "on a fresh machine both pairs are
written with equal values", and rule 2 only suppresses converged_* churn on
a later same-version re-run.
So two identical lines mean bootstrapped-and-never-re-converged, and a
manifest missing the pair is partial or hand-edited rather than fresh --
no writer produces it. The graceful degradation stays for that case, still
without backfilling from birth, which would invent a convergence that never
happened.
The reader itself was already correct; this fixes the fixture and the prose
that claimed otherwise.
Found in review of #74.
