# POST /clipboard/capture-current

`POST /clipboard/capture-current`

Capture whatever is on the OS clipboard right now into history,
without waiting for a change event (issue #1169: lets a caller preserve
a concurrent write — e.g. something copied during the daemon's startup
window — before overwriting the OS clipboard with a restored entry).
Wrapped in the canonical `{ data, ts }` envelope (ADR-008 §0.1/§0.2).
`entryId: null` means there was nothing on the OS clipboard to capture;
this is not an error.

## Response `200`

Current OS clipboard content captured (or nothing to capture)

- CaptureCurrentClipboardEnvelope — Canonical success envelope: `{ "data": T, "ts": <unix millis i64> }`. `ts` is `chrono::Utc::now().timestamp_millis()`, set in the webserver handler via [`ApiEnvelope::now`] (the contract carries only the type + the clock helper, not a hard dependency on when the handler reads the clock). `rename_all = "camelCase"` is a no-op for the single-word fields here but is declared for forward-compat. IMPORTANT (utoipa v4): every concrete `ApiEnvelope<X>` that needs a named OpenAPI component is declared in the `#[aliases(...)]` block below. Add a new alias line whenever a new payload type needs enveloping. NEVER register the bare `ApiEnvelope` in `components(schemas(...))` — utoipa errors on a bare generic, and an un-aliased generic inlines an anonymous schema.
  - `data` CaptureCurrentClipboardResponse, required — Response body for `POST /clipboard/capture-current`. `entry_id` is `None` when there was nothing on the OS clipboard to capture.
    - `entryId` string, nullable
  - `ts` integer, required — Server time when the response was built (unix epoch milliseconds).

- `500` — Internal server error
