WHAT WAS DONE:
- Added troubleshooting entry to holly-wanderer-permissions-setup.md
- Documents the gray circle symptom in Carl-bot Autoroles dashboard

- Includes fix steps and verification method

WHY:
Encountered live on 2026-03-28. New members were joining and
receiving no role. Root cause was Carl-bot's role positioned below
Wanderer in the Discord role hierarchy. One-drag fix. Documented
immediately so this is never a mystery again.

+### **Problem: Carl-bot not assigning Wanderer role to new members (role shows gray in dashboard)**
+
+**Symptoms:**
+- New members join and receive no role at all
+- In Carl-bot dashboard → Autoroles, the Wanderer role tag shows a **gray circle** on the left instead of a colored one
+
+**Root Cause:**
+Discord requires a bot's role to be **higher in the role hierarchy** than any role it tries to assign. If Carl-bot's role sits below Wanderer in the list, Discord silently blocks the assignment.
+
+**Fix:**
+1. Go to **Server Settings → Roles**
+2. Find Carl-bot's role in the list
+3. **Drag it above Wanderer**
+4. Save
+
+**Verification:**
+The Wanderer role tag in Carl-bot's Autoroles dashboard will show a **colored circle** (not gray) once the hierarchy is correct. Test with a fresh join or by removing Wanderer from a test account and rejoining.
+
+**Date Encountered:** March 28, 2026
+**Fixed By:** Michael (Frostystyle)
+**Diagnosed By:** Chronicler #45
