Resumes a paused Rollout.

**Not available yet.** Sylphx Hosting is declared in the registry but no backend serves it: every call answers `501` with the problem code `UNIMPLEMENTED`.

- **Path** `POST https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/services/service/service_rollouts/rollout:resume`
- **Scope** `hosting:write`
- **Effect** `write` — a successful call changes state.
- **Collection** [service_rollouts](/docs/api/service_rollouts)
- **Validate-only** `validate_only=true` runs every check and writes nothing

## Request

| --- | --- | --- |
| `name` | `string` | The name of the rollout. Required. |
| `etag` | `string` | Act only if the current etag matches. |
| `validate_only` | `bool` | Validate without acting. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/services/{service}/service_rollo uts/{rollout}`. |

| --- | --- | --- |
| `generation` | `int64` | Increases by one on every change to `spec`. Output only. |
| `etag` | `string` | Strong ETag (AIP-154): changes on any change to spec, status, or metadata. Send it back as `If-Match` or `etag` to make Update and Delete conditional; a mismatch fails with ABORTED / 409 `ETAG_MISMATCH`. Output only. |
| `create_time` | `timestamp` | When the Resource was created. Output only. |
| `update_time` | `timestamp` | When the Resource last changed. Output only. |

| `release` | `string` | The Release to roll out. Unset rolls out the Service's current generation; a previous Release rolls back. |

### RolloutStatus

| Field | Type | What it is |
| --- | --- | --- |
| `observed_generation` | `int64` | The generation this status was computed from. Output only. |
| `conditions` | `Condition[]` | Ready, Reconciling, Stalled. Output only. |

| `end_time` | `timestamp` | When the Rollout reached a final state. Output only. |

### Condition

| Field | Type | What it is |
| --- | --- | --- |
| `type` | `string` | The condition type, for example `Ready`. |
| `status` | `ConditionStatus` | Whether the condition holds. One of `true`, `false`, `unknown`. |
| `observed_generation` | `int64` | The generation this observation was made against. |
| `reason` | `string` | A machine-readable UpperCamelCase reason. |
| `message` | `string` | A customer-safe human-readable message. |
| `severity` | `Severity` | How severe a FALSE condition is. One of `info`, `warning`, `error`. |
| `transition_time` | `timestamp` | When `status` last changed. |
