Architecture should not be explained — it should be observable, versioned, and executable.
This repository is the platform-level specification space for the Blueprint Platform.
It exists to capture, evolve, and stabilize the contracts, concepts, and governance models that make architecture a first‑class, executable product — independent of any single engine or implementation.
blueprint-platform-spec is not an implementation repository.
It defines what must be true across the Blueprint ecosystem, not how a specific tool achieves it.
This repo is where we:
- Define architectural contracts that outlive tools and versions
- Specify capability boundaries and responsibilities
- Describe governance and versioning models
- Capture policy semantics before they become executable guardrails
- Provide a canonical reference for future platform evolution
Think of this repository as the architectural constitution of the Blueprint Platform.
Blueprint Platform is intentionally split into clear responsibility layers:
| Layer | Responsibility |
|---|---|
| Platform specs | Vision, contracts, policies, governance (this repo) |
| Engine | Executable proof of architecture (codegen-blueprint) |
| Capabilities | Reusable behavior via libraries (planned) |
| Delivery surfaces | CLI, REST, UI (evolve over time) |
📌 Important: This repository does not generate code and does not enforce rules directly. Enforcement happens through engines and tooling that implement these specifications.
The specifications in this repository may cover:
- Architecture as a Product — what it means, and what it guarantees
- Executable guardrails — intent, semantics, and failure expectations
- Architecture policy packs — conceptual rule sets and versioning strategy
- Capability governance — how cross‑cutting behavior is defined and upgraded
- Compatibility and evolution rules — what can change, and when
- Terminology and vocabulary — shared language across teams and tools
Some specifications may later:
- Be implemented as ArchUnit rules
- Be compiled into executable checks
- Or inspire higher‑level DSLs or tooling
But this repository remains the source of truth, regardless of implementation.
Specifications are expected to evolve slowly and deliberately.
Guiding principles:
- Contracts before convenience
- Explicit breaking changes
- Versioned guarantees
- Backward compatibility by default
No specification is considered final until it has:
- A clear problem statement
- Defined success and failure semantics
- A documented compatibility story
The codegen-blueprint repository:
- Implements executable proof of these ideas
- Turns specifications into build‑time guarantees
- Acts as an adoption and wiring engine for the platform
This repository guides the engine — it does not follow it.
This repository currently contains foundational vision and contracts.
Future additions may include:
- Formal specification documents (
/specs) - Governance and versioning policies
- Capability catalogs
- Policy pack definitions
Architecture as a Product Not documented. Not assumed. Specified, versioned, and enforced by construction.
