n8n Ops Safety Kit v2

Your n8n workflows run 24/7. Do you know what happened at 3 AM?n8n's built-in execution logs don't give most teams enough operational history or structure for incident review. If a webhook fires twice, an AI output goes unchecked, or a workflow fails quietly, you often find out only after something downstream breaks.v2 adds core safety primitives, now DB-backed.This kit gives you a set of reusable n8n workflows for safer production operations:New in v2Audit Log (Postgres/Supabase) — Record workflow events in a queryable database with execution_id for easier traceability and faster debugging. No Google Sheets dependency.Webhook Dedup — SHA256-based duplicate detection with configurable TTL. Skip duplicate retries and log skipped events to the audit table.Review Gate with Auto-Reject — A human review gate that fails closed on timeout. No more stalled pipelines waiting indefinitely for approval.Included from the earlier kitCircuit Breaker — Disable workflows after repeated failuresError Handler — Catch errors and route them to circuit breaker + audit flowDaily Report — Summary of what ran and what failedBudget Gate — Stop workflows when AI/API spend crosses your thresholdReview Gate (manual approval pattern) — Human approval flow for higher-risk actionsWhat you get10 workflow JSON files for n8n2 SQL schema files for Postgres / SupabaseSetup docs and environment variable templateCompatible with n8n Cloud and self-hosted setupsRequirements: n8n v1.0+, Postgres or Supabase, SMTP emailBest for: AI workflows with human review steps, webhook-heavy automations, teams that want a lightweight safety layer without building everything from scratch.This release focuses on core safety primitives. Error Trigger circuit breaker is planned as a separate follow-up module.
