Layer 3 — the product
In plain language
The product is where the platform meets people: the workshop where Matter & Gas designs and builds Solutions (Studio), the thing a client buys (a Solution), the dashboard and API through which they reach it, and the governed machinery that changes any of it. It is one deployed AWS application — Next.js on the front, forty-eight purpose-built Lambda functions behind it, composed from the substrate and composition packages below.
What it owns
- Studio — the operator surface for authoring, testing, publishing and operating Capabilities.
- Solutions — the sole commercial object: a named binding of one client to a set of Capabilities and their configuration.
- The Governed Operation Kernel — how every production change happens: dry-run, attributed approval, execute, verify, ledger.
- Per-tenant knowledge — client corpora with fail-closed isolation, explicit grants, staged ingestion and provable erasure.
- The Front Door — the public intake on matterandgas.com, itself a Solution running on the platform.
- Our API — the published v1 HTTP contract for buffered and streamed runs, relationship memory and run evidence.
- Tools — governed outward actions such as email, with review gates and allow-lists.
- The resolver — the only code that knows both
@mag/*and@magpie/*; it compiles a Capability into a workflow definition. - The customer dashboard — sign-in, entitlements, runs, subscription and team, per client tenant.

By the numbers
- 48 Lambda functions, each with its own least-privilege execution role.
- 22 architecture decision records (ADR-0001 … ADR-0011, ADR-0025 … ADR-0042).
- 622 unit-test files, roughly ten thousand test cases — including mirror suites that gate every substrate version upgrade.
- 12 registered governed operations (see the kernel page).
