Interface ScheduleTaskParams

Task end. Same accepted forms as startDate.

Unique task id within the schedule.

Marks a zero-duration milestone (startDate === endDate). Purely informational — the player surfaces these through Schedule.milestones so UIs can render them as chevrons on a timeline scrubber.

Human-readable label — surfaced in panels / tooltips.

SceneObject ids that this task installs / builds / commissions. The player reads through these to drive per-object visibility, colour, and opacity over time.

An object that appears in multiple tasks resolves to the latest-finishing task — the one that's still in-progress (or has completed most recently) at the current date wins. Pass [] for pure summary / placeholder tasks that organise the schedule but don't change any object's state.

Optional parent task id for hierarchical schedules (a summary task containing sub-tasks). The parent's own startDate / endDate typically span its children but the player doesn't enforce that — both parent and children contribute to the per-object state independently if they share objectIds.

Task start. Accepts a Date or any string Date can parse — typically an ISO 8601 like "2026-03-15" or "2026-03-15T08:00:00Z".

RGB tint applied to objects while the task is InProgress. The SchedulePlayer passes this to view.setObjectsColorized(), so the colour multiplies the underlying material. Defaults to a warm construction-orange [1.0, 0.55, 0.15] so newly-active tasks read clearly against the grey-tinted ghost state.
