+
+* 🔐 Detect Secrets Enforcement
+
+This repository uses [`detect-secrets`](https://github.com/IBM/detect-secrets-stream) to prevent committing sensitive information like API keys, tokens, and passwords.
+
+** 🚀 How It Works
+
+Secrets are tracked using a `.secrets.baseline` file. This file contains a hash of detected secret patterns and is version-controlled.
+
+On every pull request, GitHub Actions will:
+- Scan the codebase using the committed baseline.
+- Fail the build if new untracked secrets are found.
+
+** 🛠 Update the Baseline
+
+If your PR is failing due to newly detected secrets (false positives or intentional additions), follow the steps below to update the baseline:
+
+*** ✅ One-Command Update
+
+Use the provided `Makefile` to automatically install and run `detect-secrets`, then clean up:
+
+```bash
+make update-secrets
