Webhook & Third-Party Form Endpoint Health Spec Generator

2. Four End-to-End Assertions (HubSpot Forms v3 / Marketing Hub Webhook)

• Portal ID & Form GUID Verification: Asserts every 5 minutes that the live DOM form binds to your active HubSpot portalId and formGuid.
• Required Property Drift Detection: Detects when a marketing ops user marks a new HubSpot property 'Required' in the CRM without updating the website form—a classic cause of 400 Bad Request lead drops.
• Strict Privacy / Ad-Blocker Fallback Check: Verifies first-party server proxy or HTML fallback works when client scripts are blocked.
• Round-Trip Inbox & Slack Alert Assertion: Confirms the synthetic contact record triggers your internal lead notification within 120 seconds.
