+# Fix: n8n Server Health Monitor Discord Escalation Notifications Lacked Issue Details
+
+## Problem
+
+The n8n "Server Health Monitor - Master Loop" (workflow ID: `p7XmW23SgCs3hEkY`) was sending Discord escalation notifications that only showed raw issue counts — e.g., "escalation_needed (2 issues)" — with no detail about which servers had problems or what was wrong.
+
+## Root Cause
+
+The Aggregate Results node (`nodeId: code-aggregate`) in the master workflow was not formatting the issue data into human-readable output before sending to the Discord embed. It surfaced raw aggregate counts only.
+
+## Two Notification Paths
+
+The monitoring system has two distinct notification paths:
+- **Exit code 1 (auto-remediated):** Goes through `notifier.py` on CT 302 directly — this path already had good detail.
+- **Exit code 2 (escalation needed):** Goes through the n8n master workflow Discord embed — this was the broken path.
+
+Only the master workflow needed fixing.
+
+## Fix
+
+Updated the `code-aggregate` jsCode node in the master workflow via `n8n-mcp` partial update. Changes:
+
+1. **Skip healthy servers** — only unhealthy servers appear in the body; a footer shows "7/9 servers healthy".
+2. **List issues under server name** — each issue message is shown with the redundant " on {server_key}" suffix stripped.
+3. **Show remediated items** — formatted as "Restarted {container} (success)".
+4. **Include Claude remediation snippet** — when escalation was invoked, shows first 150 chars of Claude's output.
+
+## Method
+
+Updated via `mcp__n8n-mcp__n8n_update_partial_workflow` targeting `nodeId: code-aggregate` within workflow `p7XmW23SgCs3hEkY`.
