# Revise moment passages

`PUT /api/v1/projects/{projectId}/moment-sets/{momentSetId}/passages`

## Request

- Base URL: `https://prismclip.com`
- URL: `https://prismclip.com/api/v1/projects/{projectId}/moment-sets/{momentSetId}/passages`
- Auth: HTTP bearer

Replace the passages of an owned moment set using the same evidence and caption validation as the Studio review UI. Revisions are immutable: PrismClip creates and activates a new ready moment set and returns the prior ID.

## Path parameters

- `projectId` string, uuid, required
- `momentSetId` string, uuid, required

## Request body

- object
  - `passages` object[], required: Complete replacement passage list; revision creates a new immutable moment set
    - `evidence_kind` 'speech' | 'visual' | 'mixed', required
    - `first_word` integer, nullable, required
    - `last_word` integer, nullable, required
    - `start_ms` integer, required
    - `end_ms` integer, required
    - `scene_indices` integer[], required
    - `caption_corrections` object[], required
      - `ordinal` integer, required
      - `text` string, required
    - `reason` string, required

## Response `200`

The new ready revision, validated passages, and prior moment-set ID.
