Approval-route predictor for new expenses

The moment an expense is created, it predicts what will happen to it: which approval tier it hits, whether it auto-clears, or which manager and finance approver it must pass through. Clean, under-cap items are marked auto-approved; anything ambiguous is routed to the correct human with a plain-English reason, so nothing sits in an unassigned queue.

Use it when approval routing is manual and inconsistent — items bounce between approvers or stall because no one knows who owns them. This makes the routing decision deterministic and immediate.

1. 1A new record in the Airtable expenses table triggers the run.
2. 2The model evaluates the expense against policy thresholds and the approval matrix to predict its route.
3. 3A logic branch separates auto-approve, single-approver, and dual-approval outcomes.
4. 4Auto-approved items have their status and predicted path written back to Airtable.
5. 5Items needing review are sent to the assigned approver in Slack with the amount, category, and the specific rule that triggered review.
