Requirements

The specification: vision, system requirements, use cases, technology stack, testing, workflow, and operations.

These seven documents are the specification for Heimdall UI. The rest of the application documentation describes how to run and ship it; these say what must be true.

They are also the working documents of the project, not a retrospective write-up: a screen is built by picking a use case, following its main and alternative flows, and citing the requirement identifiers in the code.

DocumentWhat it settles
Vision DocumentWhy Heimdall UI exists, who it serves, its stakeholders, goals, and what success looks like.
System Requirements DocumentThe functional and non-functional requirements, the screen inventory, and the authorization matrix.
Use Case Specification DocumentThe Heimdall UI use cases (UI-01 to UI-39), their flows, and how each one traces back to the API use cases it consumes.
Technology Stack DocumentThe technologies, libraries, and pinned versions Heimdall UI is built on, and how the API client is generated.
Testing Specification DocumentHow each use case is tested: the levels, the naming convention, the structure, and what coverage means here.
Development Workflow DocumentHow a use case goes from backlog to merged: branch, issue status, testing gate, pull request.
Operations & Infrastructure DocumentHow Heimdall UI is configured, built, packaged, and released for each of its four targets and four environments.
