# Error Journal Entry: Template Mismatch / Shadow Directory

**Date:** 2026-06-07
**Issue:** Changes to `index.html` were not appearing on the live website at `http://localhost:5050`.

**Root Cause:**
A redundant nested directory structure existed: `/home/vincent/quality_small_engine_mock/quality_small_engine_mock/`. 
The running Flask process was serving files from this "shadow" directory instead of the intended root directory. This caused a mismatch between the file size on disk (15989 bytes) and the content length being served (12419 bytes).

**Resolution:**
1. Identified the conflicting PID.
2. Terminated the existing Flask processes.
3. Removed the redundant nested directory: `rm -rf quality_small_engine_mock/quality_small_engine_mock`.
4. Restarted the server from the correct root directory.
5. Verified the fix by checking that the "What Our Customers Say" section is now present in the HTTP response.

**Prevention:**
Avoid creating nested project folders with the same name during initialization or git clones. Use `ls -R` to audit directory structures if content mismatches occur.
