Notes and record state

Record note
Entity-level umbrella record. v0/v1, v2, and v3 milestones are recorded here. Deployment-level and chain-level modeling is still pending, so this is not yet split by deployment.
Revision state
Records may be incomplete, approximate, contested, or revised as better evidence becomes available.
This record may be incomplete or revised. Dead-side entries prefer archived URLs over original domains. Dates, causes, and classifications may change when stronger evidence becomes available. Contact / corrections
