A weekly-report handoff needs the current draft, source queries or exports, reporting period, metric definitions, anomaly notes, and publication channel. Show which numbers have been reconciled and which remain provisional. Give the new owner access to the approved data source rather than copying sensitive raw records into a public thread.
Ask them to reproduce one key figure before accepting the report. Record the next extraction time, reviewer, and publication deadline. Preserve prior versions so a correction can be traced without overwriting history. If the new owner cannot explain where a headline number came from, delay approval until the source path is clear.
