10.1 Objective

Close out remaining loose ends before final review: a proper repo-level README, one last end-to-end smoke test, and a quick review of the repo for leftover artifacts from troubleshooting sessions.

10.2 Repo README

Added a README.md to the repository root covering: project overview, architecture diagram (text form), tech stack, deployment flow, security design, rollback strategy, monitoring setup, and a replication guide for anyone rebuilding this from scratch. Kept separate from this document - the README is a concise repo-facing summary, this document is the full detailed walkthrough.

10.3 Final Smoke Test

• Pushed a final small change to main and confirmed it flowed through the pipeline automatically to the live HTTPS URL
• Confirmed the CloudWatch 5xxErrorRate alarm remained healthy (no errors) throughout
• Reviewed the repository for leftover test commits/files from earlier troubleshooting (e.g. the intentionallybroken commit from Day 15-17) - left in place as they’re part of the genuine history and don’t affect the working state

10.4 Checkpoint Summary

• Status: Done
• Outcome: Repository is complete, documented, and passes a final end-to-end smoke test
• Blockers: None

11. Day 24: Documentation

11.1 Objective

Ensure the project is properly documented for both the internship deliverable and anyone else who might pick this project up.

11.2 Deliverables

• CICD_Devops_Journey.docx (this document) - full day-by-day technical walkthrough, including every command, every configuration decision, and every issue encountered with its resolution
• README.md - concise, repo-facing summary: architecture, tech stack, security design, and a replication guide
• Progress tracker (Section 2) - at-a-glance status of all 25 days
