  - `data` object, required: Job object delivered in the Mux webhook event's data field. The event type identifies the workflow and transition.
    - `id` string, required: Unique job identifier.
    - `passthrough` string: Arbitrary string supplied at creation, returned as-is.
    - `units_consumed` integer, required: Number of Mux AI units consumed by this job.
    - `directive` object: The directive run that dispatched this job. Absent for jobs created via direct API POST.
      - `id` string, required: ID of the directive that dispatched this job.
      - `run_id` string, required: ID of the specific directive run that dispatched this job.
    - `created_at` integer, required: Unix timestamp (seconds) when the job was created.
    - `updated_at` integer, required: Unix timestamp (seconds) of the job's last state transition (e.g. when it started processing or reached a terminal state).
    - `workflow` 'find-scenes', required
    - `parameters` object, required
      - `asset_id` string, required: The Mux asset ID of the video asset to segment into scenes. Audio-only assets are not supported.
      - `language_code` string: Preferred transcript language code to analyze when a matching transcript track is available. Defaults to the first ready transcript track on the asset.
      - `min_scenes` integer: Optional lower-bound hint for scene segmentation. When provided, the model should avoid collapsing clearly distinct beats below this count when the content supports more granular scene boundaries.
      - `min_scene_duration_ms` integer: Preferred minimum scene duration in milliseconds for scaffolded transcript chunking. Defaults to 15000.
      - `output_steering` object: Curated output_steering controls for execution scope, segmentation strategy, title style, narration detail, audience, brand terms, and topic taxonomy. Scope is enforced; other controls guide model behavior but do not guarantee exact output.
        - `scope` object: Optional execution window in seconds on the original asset timeline. The range must contain a video frame at the asset frame rate. Omit start_time to begin at the asset start and omit end_time to continue through the asset end. Returned scene timestamps remain absolute asset timestamps.
          - `start_time` number: Start of the execution window in seconds from the beginning of the media. When omitted, the window starts at the beginning.
          - `end_time` number: End of the execution window in seconds from the beginning of the media. When omitted, the window extends to the end.
        - `segmentation_strategy` 'editorial_beats' | 'topic_changes' | 'visual_transitions' | 'action_progression' | 'instructional_steps': Best-effort guidance for the kinds of boundaries the scene finder should prefer.
        - `title_style` 'descriptive' | 'editorial' | 'search_optimized' | 'accessibility': Best-effort title style guidance for generated scene titles.
        - `narration_detail` 'concise' | 'balanced' | 'detailed': Best-effort guidance for how much detail scene narratives should include.
        - `audience` string: Intended audience used as best-effort model guidance. Does not change the output schema.
        - `brand_terms` string[]: Preferred brand or domain terms to use when supported by source evidence.
        - `topic_taxonomy` object: Controlled vocabulary used to steer scene concepts without changing the response schema.
          - `name` string: Optional customer-facing name for the taxonomy.
          - `values` object[], required: Controlled vocabulary values used as best-effort model guidance.
            - `label` string, required: Canonical taxonomy value to prefer when supported by the source content.
            - `description` string: Short explanation of when this value applies.
            - `aliases` string[]: Accepted alternate names that should normalize to the canonical label.
          - `allow_other` boolean, required: When false, the model should prefer values from the taxonomy. When true, non-taxonomy values may be used when no taxonomy value applies.
    - `status` 'pending' | 'processing' | 'completed' | 'errored' | 'cancelled', required: Current job status.
    - `errors` object[]: Error details. Present when status is 'errored'.
      - `type` string, required: Stable public error category identifier.
