Add Task #91: Fix Server Matrix node detection

Problem: Servers without -TX/-NC in name don't appear in Trinity Console
Root cause: Grouping logic filters by name substring, not node ID
Affected: 6 of Holly's new servers not showing

Fix requires:
1. Update discovery.js to include nodeId from API
2. Update servers.js to group by node ID instead of name

Waiting for: Michael to get home (needs MobaXterm + node IDs from Panel)

+# Task: Fix Server Matrix Node Detection
+
+**Task ID:** #91  
+**Created:** April 4, 2026  
+**Status:** In Progress — waiting for Michael to get home (needs MobaXterm)  
+**Priority:** High (blocking Holly's new servers from appearing)
+
+---
+
+## Problem
+
+Holly added 6 new servers ~2 hours ago. They don't appear in Trinity Console Server Matrix.
+
+**Root Cause:** The matrix grouping logic filters servers by either:
+1. Node name matching ("TX1", "NC1", "Node 2", "Node 3")
+2. Server name containing "TX" or "NC"
+
+Servers that match NEITHER condition fall through and aren't displayed.
+
+**Affected Servers (not showing):**
+- Beyond Ascension
+- Wold's Vaults
+- Otherworld [Dungeons & Dragons]
+- DeceasedCraft
+- Submerged 2
+- (1 more — 18 total, 12 showing)
+
+**Servers showing (have -TX or -NC suffix):**
+- Mythcraft 5 - NC
+- Create Plus - TX
+- Vanilla - TX
+- Beyond Depth - TX
+- (8 more)
+
+---
+
+## The Fix
+
+### Part 1: Update discovery.js
+
+**File:** `/home/claude/firefrost-services/services/arbiter-3.0/src/panel/discovery.js`
+
+**Change:** Add `nodeId` to the returned server object.
+
+```javascript
+// Line 25-28, change from:
+}).map(server => ({
+  identifier: server.attributes.identifier,
+  name: server.attributes.name
+}));
+
+// To:
+}).map(server => ({
+  identifier: server.attributes.identifier,
+  name: server.attributes.name,
+  nodeId: server.attributes.node
+}));
+```
+
+### Part 2: Update servers.js grouping logic
+
+**File:** `/home/claude/firefrost-services/services/arbiter-3.0/src/routes/admin/servers.js`
+
+**Change:** Replace name-based filtering with node ID filtering.
+
+```javascript
+// Line 47-48, change from:
+const txServers = enrichedServers.filter(s => s.node === 'TX1' || s.node === 'Node 3' || s.name.includes('TX'));
+const ncServers = enrichedServers.filter(s => s.node === 'NC1' || s.node === 'Node 2' || s.name.includes('NC'));
+
+// To (replace X and Y with actual node IDs):
+const TX_NODE_ID = X;  // Get from Pterodactyl Admin → Nodes
+const NC_NODE_ID = Y;  // Get from Pterodactyl Admin → Nodes
+
+const txServers = enrichedServers.filter(s => s.nodeId === TX_NODE_ID);
+const ncServers = enrichedServers.filter(s => s.nodeId === NC_NODE_ID);
+```
+
+---
+
+## Information Needed
+
+Before implementing, get from Pterodactyl Admin → Nodes:
+
+- [ ] **TX1 (Dallas) Node ID:** ___
+- [ ] **NC1 (Charlotte) Node ID:** ___
+
+---
+
+## Implementation Steps
+
+1. SSH to Command Center (63.143.34.217) via MobaXterm
+2. `cd /path/to/arbiter-3` (verify actual path)
+3. Edit `src/panel/discovery.js` — add nodeId
+4. Edit `src/routes/admin/servers.js` — update grouping logic with node IDs
+5. Restart Arbiter: `sudo systemctl restart arbiter-3`
+6. Verify all 18 servers appear in Trinity Console
+7. Commit changes to Gitea
+
+---
+
+## Future Consideration
+
+**Also discussed:** Removing the nest filter entirely for future expansion (Ark, Palworld, etc.)
+
+Current filter: `MINECRAFT_NEST_IDS=1,6,7`
+
+**Recommendation:** Consult Gemini before removing — may have downstream implications for whitelist sync trying to write to non-Minecraft servers.
