task_pages__timeline__relative_position_event_label

Identity

1. Domain: pages
2. Scene id: timeline
3. Source scene: timeline
4. Task id: task_pages__timeline__relative_position_event_label

Program Contract

1. Program schema: timeline_relative_position_event_label(reference_date, direction, offset) -> event_label; scene=timeline; scope=relative_position_event_label
2. Scene: timeline
3. Scope: one rendered milestone timeline with dated event cards and one prompt-specified reference date belonging to a visible event card.
4. Supported query_id values: event_before_dated_event_label, event_after_dated_event_label
5. Answer schema: string
6. Annotation schema: bbox
7. Annotation roles: bounding box of the target event card at the requested timeline offset.
8. Query arguments: direction=before|after; offset=1..4 is sampled as a prompt parameter, not a query id.
9. Render arguments: month/year, event count, scene variant, style variant, accent color, render dimensions, and post-render noise.

Prompt + Trace

1. Prompt bundle: pages_timeline_v1
2. Scene key: milestone_timeline
3. Task key: timeline_milestone_query
4. Prompt query keys: event_before_dated_event_label, event_after_dated_event_label
5. Trace records selected query_id, reference date, reference event id, offset, direction, target event id, event order, dates, event-card bboxes, style metadata, and projected annotation.
6. Generation is deterministic from instance_seed; answer and annotation come from the finalized render metadata.
