This commit refined diagnostics for webhook payload traceability — switching terminology from “Event routing” to “JSON snapshots” for public clarity.

This structure gives remixers and civic technologists the full blueprint for debugging webhook behavior, tracing malformed requests, and inspecting output through both JSON logs and browser previews.

“A webhook that logs what it receives is more reliable than one that only reacts.”

🧪 Validation Tools

Use test.sh to manually confirm that endpoints like /api/webhook respond correctly.

Payload snapshots are recorded under diagnostics/webhook-payloads. If they’re timestamped and growing, your webhook is live.
