Remove three never-used surfaces flagged in branch self-review: - PromptSource::writer / with_writer (unwired since the crate's first commit; Arc<dyn Write> couldn't even be written to without interior mutability, so the seam never worked as intended) - OidcSession::is_openbao_token_expired (duplicated is_expired, no callers) - HARMONY_SECRETS_URL env var (defined, never read) Log before swallowing real StoreSource::get errors so a down or misconfigured OpenBao is no longer indistinguishable from "key absent". Docs: ADR 020-1 now documents the actual OPENBAO_URL/VAULT_ADDR var (the agnostic HARMONY_SECRETS_URL it proposed was never built) with the adapter-layer-vs-domain rationale; rename stale ConfigManager references to ConfigClient in ROADMAP/01 and a firewall_pair comment.

Harmony Documentation Hub
Welcome to the Harmony documentation. This is the main entry point for learning everything from core concepts to building your own Score, Topologies, and Capabilities.
1. Getting Started
If you're new to Harmony, start here:
- Getting Started Guide: A step-by-step tutorial that takes you from an empty project to deploying your first application.
- Core Concepts: A high-level overview of the key concepts in Harmony:
Score,Topology,Capability,Inventory,Interpret, ...
2. Use Cases & Examples
See how to use Harmony to solve real-world problems.
- OPNsense VM Integration: Boot a real OPNsense firewall in a local KVM VM and configure it entirely through Harmony. Fully automated, zero manual steps — the flashiest demo. Requires Linux with KVM.
- PostgreSQL on Local K3D: Deploy a production-grade PostgreSQL cluster on a local K3D cluster. The fastest way to get started.
- OKD on Bare Metal: A detailed walkthrough of bootstrapping a high-availability OKD cluster from physical hardware.
3. Component Catalogs
Discover existing, reusable components you can use in your Harmony projects.
- Scores Catalog: A categorized list of all available
Scores(the "what"). - Topologies Catalog: A list of all available
Topologies(the "where"). - Capabilities Catalog: A list of all available
Capabilities(the "how").
4. Developer Guides
Ready to build your own components? These guides show you how.
- Writing a Score: Learn how to create your own
ScoreandInterpretlogic to define a new desired state. - Writing a Topology: Learn how to model a new environment (like AWS, GCP, or custom hardware) as a
Topology. - Adding Capabilities: See how to add a
Capabilityto your customTopology.
5. Architecture Decision Records
Harmony's design is documented through Architecture Decision Records (ADRs). See the ADR Overview for a complete index of all decisions.
