- [ ]  Repo description is in place, describing the use case and technologies used in the solution

## Source code structure and conventions

- [ ]  Infrastructure as code is in place (`/infra` folder where applicable, manifest files or code generators in the case of `Aspire` and similar )
- [ ]  Azure services configuration (/azure.yml file) is in place
- [ ]  Minimum coverage tests are in place

## Functional requirements

- [ ]  `azd up` successfully provisions and deploys a functional app
- [ ]  GitHub Actions run tasks without errors
- [ ]  DevContainer has been tested locally and runs
- [ ]  Codespaces run [locally and in browser]
- [ ]  All tests pass

In the absence of e2e tests,

- [ ]  The application has been manually tested to work as per the requirement

Audit the repository against the checklist, starting with README.md, LICENSE.md, SECURITY.md, CONTRIBUTING.md, .github/CODE_OF_CONDUCT.md, the issue template, .github/workflows/azure-dev.yml, /.devcontainer, /infra, and /azure.yml. Run the stated azd up, GitHub Actions, DevContainer, Codespaces, and test checks; done means the required repository files and labels exist and all listed functional checks pass.
