Validate new campaign links against the UTM taxonomy registry

Every time a campaign link is added to your Airtable campaign registry, this workflow tears apart the URL's UTM parameters and grades them against your house naming rules — allowed sources, lowercase-only mediums, the campaign slug pattern, and required fields. It then stamps the row with a clean Pass or a Fail plus a precise list of what broke.

Use it when your team registers campaign links in Airtable before launch and you want a gate that catches malformed UTMs at entry — instead of discovering three weeks later that half your traffic landed in `(not set)`.

1. 1An Airtable record-created trigger fires on the Campaigns table.
2. 2A logic step parses the URL and extracts utm_source, utm_medium, utm_campaign, utm_content, and utm_term.
3. 3A logic step evaluates each value against the taxonomy rules and builds a violations list.
4. 4A branch routes Pass vs Fail.
5. 5An Airtable update writes the verdict, the normalized values, and any violation messages back to the record.
