/claim #19

Adds a standalone enterprise webhook delivery failure guard for Enterprise Tooling.

Webhook Delivery Guard

• Checks retry budget and exponential backoff before integration-ready status
• Requires idempotency keys for institutional subscribers
• Holds stale failures without dead-letter routing
• Requires recent success evidence before an integration is marked healthy
• Flags missing subscriber ownership
• Redacts emails and token-like values from failure packets
• Emits deterministic JSON, Markdown, SVG, and MP4 demo artifacts

Demo And Validation

• node --check enterprise-webhook-delivery-guard/test.js
• node enterprise-webhook-delivery-guard/demo.js -> generated JSON/Markdown/SVG reports
• python enterprise-webhook-delivery-guard/make-demo-video.py -> generated demo MP4
• MP4 decode/read check returned a 720x1280 RGB frame
• Report spot checks found no synthetic email/token leakage
