Salesforce SFDX Custom Objects Deployment

I have already created two custom objects—Integration Log and Integration Log Detail—in a sandbox and everything (fields, page layouts, related lists) is set up exactly the way I want. Now I need those objects deployed into another org with the same structure and visibility.

My preferred route is Salesforce CLI (SFDX). What I mainly need is guidance and hands-on help generating the correct metadata package so I can retrieve the objects from the source org and push them cleanly to the target org.

Key points to cover:
• Build or adjust the SFDX project so it captures both custom objects, their page layouts, related lists, and any associated metadata (record types, list views, etc. if applicable).
• Include field-level security settings and custom object permissions in the deployment package so user profiles in the destination org inherit the same access.
• Walk me through (or script) the authorize, retrieve, convert, and deploy steps so I can repeat the process confidently in future.

Acceptance criteria for completion:
1. Deployment runs without errors via Salesforce CLI.
2. In the destination org I can open Integration Log and Integration Log Detail and see every field, page layout, and related list exactly as in the sandbox.
3. Field-level security and object-level permissions match the source org for the relevant profiles.

If you’re comfortable with SFDX metadata packaging and can get this done efficiently, let’s get started.
