Using Git as the authoritative source instead of an additional copy
Git is the sole source when production code changes originate from verified commits and server files are not considered a parallel version.
For developers and technical project managers, "establishing Git as the authoritative source" can be assessed primarily based on two points: "origin of change" and "repository as a retrospective." This comparison makes the functional boundary tangible.

What rules make Git the only reliable source for application code?
Git becomes authoritative when production code originates exclusively from released commits or artifacts built from them. Direct changes are considered drift and are not subsequently declared the new starting point.
Repository as a retrospective
Repository as a retrospective – Changes are only partially copied back after server processing.
Local Truth – An unpushed workstation contains the only working version.
Unversioned Artifact – Production files have no verifiable origin and cannot be assigned to a commit or a released artifact.
Change Origin
Change Origin – Code only reaches production via commit, review, and a defined delivery path.
Version Assignment – The running service displays the commit or artifact identifier in a traceable manner.
Drift Handling – Deviations are reported and replaced with a regular patch, instead of retroactively legitimizing the special production state.
Test Case: "Repository as an Addendum"
A functioning server file differs from the repository. Instead of downloading it as a new starting point, the cause is investigated, committed as a patch, and deployed normally; subsequently, the production state matches its identifier again.
Drift Handling
Production file states without a corresponding released commit.
Direct or back-copy changes outside the regular review process.
Version Assignment
All paths into the production code path are examined for their origin.
Deployment and state display are tied to released commits or artifacts.
Server and local discrepancies are cleaned up once and then automatically detected.

If you want to practically implement "establishing Git as the authoritative source," you can refer to Robust Website Systems . This focuses on "authoritative version source" and "source of changes."
Conclusion: Establishing Git as the authoritative source
An authoritative source requires a consistent change path. Git only provides security when production is derived from it.
Sources and Further Information
The following official documentation and standards provide the technical classification.
Git workflows – Git DocumentationThe official Git documentation describes small independent changes, integration branches, and reasoned workflow decisions.
Secure Software Development Framework Version 1.1 – NIST SP 800-218The NIST framework requires integrity, provenance, and controlled changes of software components throughout their lifecycle.
Key Thesis
Changes begin in the repository, undergo review and testing, and are deployed as an identifiable artifact. Direct changes and unversioned copies are considered drift and are not declared back to the standard.
What This Is Not About
Git is not an archive copy alongside production files and local folders with its own version of the code.
What it's about
Every code change begins in the repository, undergoes review, and is delivered as an identifiable version.
Git, deployment, and quality assurance
Keeping files synchronized between the local system, repository, and server
Establishing Git as the authoritative source requires a separate checklist: How do you prevent conflicting file states between the local system, Git, and server?
