## Reference · Integrations

> **Reference purpose** — Grow the ecosystem through discoverable capabilities, lifecycle hooks, and compatibility metadata.

Integrations that can be registered, searched, evaluated, upgraded, and removed safely.

### Contract summary

| Property  | Definition   | Review question                 |
| --------- | ------------ | ------------------------------- |
| Metadata  | What it does | Discoverability and comparison. |
| Lifecycle | When it runs | Safe startup and shutdown.      |
| Maturity  | How trusted  | Adoption and risk signal.       |

### Interpretation

An ecosystem scales through governance and quality signals, not by accumulating an uncurated list of providers.

> An ecosystem becomes powerful when integration quality is legible.

### Implementation notes

| Engineering move            | Guidance                                                                           |
| --------------------------- | ---------------------------------------------------------------------------------- |
| **Describe the capability** | State supported operations, runtime, limits, and provider requirements.            |
| **Register metadata**       | Make discovery useful without forcing every application to install every provider. |
| **Define hooks**            | Specify startup, shutdown, health, and configuration lifecycle.                    |
| **Publish compatibility**   | Version the integration contract and document support expectations.                |

### Decision lens

| Mode         | Practical emphasis                                             |
| ------------ | -------------------------------------------------------------- |
| **Catalog**  | Browse providers by capability and maturity.                   |
| **Plugin**   | Load lifecycle behavior with explicit ownership.               |
| **Internal** | Register organization-specific adapters with private metadata. |
