Type · `import type { Capability } from '@holostep-configurators/runtime-client/contract';` · stable · since 2.0.0 · section 19. Info and capabilities

Open, so an app built against a newer contract can ask about ids this runtime lacks. An id not
in this runtime's [`KnownCapability`](KnownCapability.md) answers false and records 'unknown-capability' once per id
per session: a 1.4 id such as 'idle', and a newer contract's id, where it is information only.

## Declaration

```ts
export type Capability = KnownCapability | (string & {});
```

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `Capability` names no product |
| 2. A precedent | not recorded: no ledger row (coverage.json) names this member or its owner |
| 3. Two apps, or labs | pass: 17 apps (fleet cross-check: app-37356bf09f, app-4f16d2f6da, app-4fd23bc869, app-822bb9d6aa, app-8675b3225c, app-bcb7ef21da, app-c1384707fc, app-ceb4eccc72 and 9 more) |
| 4. The cheaper fix first | not recorded per member (Appendix B decides it per need) |
