## Definitions

### `network.bsky.jetstream.subscribeEvents#info`

**Type**: `object`

An advisory, non-fatal notice about the stream (mirrors com.atproto.sync.subscribeRepos#info). Carries no seq and does not advance the cursor. OutdatedCursor is sent as the first frame when a unix-microseconds timestamp cursor below the retention floor was clamped up to the floor; the message names the seq actually resumed from.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `name` | `string` | Yes |  |
| `message` | `string` | No |  |

### `network.bsky.jetstream.subscribeEvents`

**Type**: `subscription`

Stream every archived and live Jetstream event in seq order, framed per the xrpc.v1.json subprotocol. The kinds, dids, and collections filters are independent predicates ANDed together; each is match-all when omitted. See the parameter and error descriptions for cursor, filtering, and compression semantics.

### `network.bsky.jetstream.subscribeEvents#sync`

**Type**: `object`

An archived #sync event (broken commit chain; consumers should resync the repo), wrapping the upstream firehose event verbatim. Never emitted on the legacy v1 /subscribe wire.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `did` | `string` (did) | Yes |  |
| `seq` | `integer` | Yes |  |
| `sync` | `ref` → `com.atproto.sync.subscribeRepos#sync` | Yes | The upstream event; its seq and time are the upstream relay's, not Jetstream's. |
| `time` | `string` (datetime) | Yes | The time Jetstream witnessed this event, microsecond precision. Timestamp imports apply only to record (commit) events, so this is always the witnessed time. |

### `network.bsky.jetstream.subscribeEvents#commit`

**Type**: `object`

A single record mutation (create, update, or delete).

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `cid` | `string` (cid) | No | CID of the record. Absent for deletes. |
| `did` | `string` (did) | Yes |  |
| `rev` | `string` (tid) | Yes | The repo rev of the commit that produced this op. |
| `seq` | `integer` | Yes | Jetstream's monotonic per-event sequence number; the stream cursor. |
| `rkey` | `string` (record-key) | Yes | Record key. |
| `time` | `string` (datetime) | Yes | The event's display timestamp, microsecond precision: when Jetstream witnessed the event, unless an operator timestamp import overrode it. Timestamp cursors translate against the witnessed time, so after an import this value may not be a faithful resume position. |
| `record` | `unknown` | No | The record decoded to JSON. Absent for deletes. |
| `operation` | `string` | Yes |  |
| `collection` | `string` (nsid) | Yes | Collection NSID of the record. |

### `network.bsky.jetstream.subscribeEvents#account`

**Type**: `object`

An account status change (active/deactivated/deleted/...), wrapping the upstream firehose event verbatim.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `did` | `string` (did) | Yes |  |
| `seq` | `integer` | Yes |  |
| `time` | `string` (datetime) | Yes | The time Jetstream witnessed this event, microsecond precision. Timestamp imports apply only to record (commit) events, so this is always the witnessed time. |
| `account` | `ref` → `com.atproto.sync.subscribeRepos#account` | Yes | The upstream event; its seq and time are the upstream relay's, not Jetstream's. |

### `network.bsky.jetstream.subscribeEvents#identity`

**Type**: `object`

An identity change (handle or DID document update), wrapping the upstream firehose event verbatim.

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `did` | `string` (did) | Yes |  |
| `seq` | `integer` | Yes |  |
| `time` | `string` (datetime) | Yes | The time Jetstream witnessed this event, microsecond precision. Timestamp imports apply only to record (commit) events, so this is always the witnessed time. |
| `identity` | `ref` → `com.atproto.sync.subscribeRepos#identity` | Yes | The upstream event; its seq and time are the upstream relay's, not Jetstream's. |
