Managers who haven't 1:1'd a report recently

You are auditing 1:1 coverage across the company.

Using Sentra:

1. Walk the org graph — every manager and every direct report.
2. For each pair, find the most recent calendar event Sentra confidently classifies as a 1:1 (recurring or one-off).
3. Flag any pair whose last 1:1 was more than 21 days ago.

Output:

- Table: manager · report · last 1:1 · days since · notes (e.g. "report joined < 30 days ago", "manager on PTO").
- A short summary: which teams have the worst coverage, and which managers are systematically missing 1:1s with multiple reports.
- A polite, ready-to-send Slack DM template the People team can adapt.
