How this log works
This timeline aggregates every dated signal on the record (creation, deployments across the company's models, verified media, incidents, and Arc G field changes), newest first. A verified event is independently confirmed; an unverified one is recorded but not yet field-verified. The Arc G field-change log is forward-only: it accrues from Arc G adoption (2026-06-04) and records material changes as they flow through the updateEntityField chokepoint. Nothing is edited silently.
