# CognitionAcp.CompletedTimestampMeta

> Metadata carrying when a started run's completion event occurred.

A completion update merges into the started tool call, whose
`cognition.ai/timestamp` stays anchored to the start event (the visible
row's time). Set on completions whose timing the transcript needs as
well — e.g. the cloud proxy's `scripted_tools` update — so clients can
end a run at its completion (mirrors `client_side_completed.timestamp` in
the webapp). Epoch milliseconds from proxy replay, ISO 8601 when live.

Like \[`ShellIdMeta`], this struct is designed to be merged standalone into
any tool call's `_meta` via \[`Meta::merge_into`].

```typescript
type CompletedTimestampMeta = void
```
