- Confirm privilege boundaries and confidentiality flags from counsel.
- Populate the template below with verified facts only — attribute each assertion to a source and date.

Pitfalls
- Speculation: Label unknowns explicitly. Do not opine on liability — describe exposure factors only.
- Timezone drift: Use consistent date/time with timezone; maintain a single chronological basis.
- Jurisdiction scope: List all jurisdictions implicated by affected individuals, not just HQ location.
- Unverified citations: Mark uncertain legal citations or deadlines with
[VERIFY].
