ReplayThe OSDU platform this proof ran on was a time-boxed environment, now decommissioned. This console replays the evidence bundle exported before it closed — 342 records with every version body, verbatim. The top-down slider re-runs the same ISO 25624-1 reconciliation in memory. Your changes are yours alone — other visitors keep seeing the pristine proof state — and they expire after an hour. Reference implementation · Read the proof
