Lists a lease's events in order. With `wait`, blocks up to that long for an event after `page_token` (long poll).

- **Path** `GET https://api.sylphx.com/v1/orgs/acme/projects/shop/envs/production/leases/lease/lease_events`
- **Scope** `sandboxes:read`
- **Effect** `read` — nothing is written.
- **Collection** [lease_events](/docs/api/lease_events)
- **Query** `page_size`, `page_token`, `filter`, `wait`
- **Pagination** the answer carries `lease_events` and, when there is more, `next_page_token`

## Request

| Field | Type | What it is |
| --- | --- | --- |
| `parent` | `string` | The lease. Required. |
| `page_size` | `int32` | At most this many; default 50, clamped to 1000. |
| `page_token` | `string` | `next_page_token` of the previous page. |
| `filter` | `string` | AIP-160 filter over `kind`. |
| `wait` | `duration` | Block up to this long (at most 60 seconds) when there is no event after `page_token`. |

## Response

| Field | Type | What it is |
| --- | --- | --- |
| `lease_events` | `LeaseEvent[]` | The page, oldest first. |
| `next_page_token` | `string` | Pass it back to continue after the last event; set on every page, so a caller can long-poll from it. |

### LeaseEvent

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/leases/{lease}/lease_events/{lease_event}`. |
| `uid` | `string` | `lev_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `kind` | `LeaseEventKind` | What happened. Output only. One of `granted`, `ready`, `refused`, `ended`, `renewed`, `network_changed`, `control_acquired`, `control_released`, `control_expired`, `budget_warning`, `paused`, `resumed`. |
| `sequence` | `int64` | The position in the lease's event sequence, from 1. Output only. |
| `occur_time` | `timestamp` | When it happened. Output only. |
| `lease_generation` | `int64` | The lease generation after the event. Output only. |
| `state` | `LeaseState` | The lease state after the event. Output only. One of `requested`, `granted`, `ready`, `paused`, `ending`, `ended`, `refused`. |
| `end_reason` | `EndReason` | For LEASE_ENDED. Output only. One of `released`, `expired`, `idle`, `cpu_budget`, `cost_budget`, `abuse`, `quota`, `org_deleted`, `machine_lost`, `boot_failed`. |
| `usage` | `LeaseUsage` | For LEASE_ENDED: final usage. Output only. |
| `control` | `ControlState` | For CONTROL_* events: the control after the event. Output only. |
| `control_duration` | `duration` | For CONTROL_RELEASED and CONTROL_EXPIRED: how long control was held. Output only. |
| `principal` | `string` | The principal that caused it, when a caller did. Output only. |

### ResourceMeta

| Field | Type | What it is |
| --- | --- | --- |
| `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. |
| `delete_time` | `timestamp` | Set while the Resource is being deleted. Output only. |

| `cost_micros` | `int64` | List-price cost so far, in millionths of a US dollar; 0 on classes that are not priced. Output only. |
| `measure_time` | `timestamp` | When this usage was measured. Output only. |
