* Generation 2 Proof of Concept: Git Storage (Notes)
|
|
*
|
|
* This module demonstrates interacting with Git Notes in a completely
|
|
* isolated, real Git environment using Deno.Command. It sets up a local
|
|
* Git repository on the fly to avoid polluting the main project repo,
|
|
* thereby proving production-readiness of the local-first storage mechanism.
