# Store page-wide baseline snapshot as a system file

`POST /api/v0/tasks/{id}/baseline-page`

## Request

- Base URL: `https://app.vibeflow.tools`
- URL: `https://app.vibeflow.tools/api/v0/tasks/{id}/baseline-page`
- Auth: HTTP bearer

P3-A cutover: the second local baseline handler (POST /api/tasks/:id/baseline-page) keeps its own op — stores { page: { version: 1, elements, capturedAt, truncated } } as the baseline-page.json system file. Scope tasks:write per the published CLI online-mode call. Write — Phase 3.

## Path parameters

- `id` string, required

## Response `200`

Store page-wide baseline snapshot as a system file — success

- object

## Other responses

- `400`: Malformed request (includes invalid task/comment id form)
- `401`: Missing or invalid principal
- `403`: Lacking scope or membership
- `404`: Unknown id
- `429`: Rate limited — cloud per-token quota exceeded (reads 300/min, writes 60/min, token creation 10/hour); counters are per-replica, so the effective limit is the configured value × replicas. The response carries Retry-After.
