+# Troubleshooting: [Clear Problem Title]
+
+## Problem
+[1-2 sentence clear description of the issue and what the user experienced]
+
+## Environment
+- Module: [Name or "CORA system"]
+- Rails Version: [e.g., 7.1.2]
+- Affected Component: [e.g., "Email Processing model", "Brief System service", "Authentication controller"]
+- Date: [YYYY-MM-DD when this was solved]
+
+## Symptoms
+- [Observable symptom 1 - what the user saw/experienced]
+- [Observable symptom 2 - error messages, visual issues, unexpected behavior]
+- [Continue as needed - be specific]
+
+## What Didn't Work
+
+**Attempted Solution 1:** [Description of what was tried]
+- **Why it failed:** [Technical reason this didn't solve the problem]
+
+**Attempted Solution 2:** [Description of second attempt]
+- **Why it failed:** [Technical reason]
+
+[Continue for all significant attempts that DIDN'T work]
+
+[If nothing else was attempted first, write:]
+**Direct solution:** The problem was identified and fixed on the first attempt.
+
+## Solution
+
+[The actual fix that worked - provide specific details]
+
+**Code changes** (if applicable):
+```ruby
+# Before (broken):
+[Show the problematic code]
+
+# After (fixed):
+[Show the corrected code with explanation]
+```
+
+**Database migration** (if applicable):
+```ruby
+# Migration change:
+[Show what was changed in the migration]

+# Steps taken to fix:
+[Commands or actions]
+```
+
+## Why This Works

+[Technical explanation of:]
+1. What was the ROOT CAUSE of the problem?
+2. Why does the solution address this root cause?
+3. What was the underlying issue (API misuse, configuration error, Rails version issue, etc.)?
+
+[Be detailed enough that future developers understand the "why", not just the "what"]
