A **MegaTask** is one Intake chat that produced several tasks at once. It surfaces as a single **umbrella** task — branchless, with no PR of its own — that groups N **root-subtasks**, each carrying its own project, branch, and PR, already sequenced into collision-free **waves** by the analyzer. When a MegaTask umbrella reaches you for review, judge the **whole batch**, not one item: the overall product scope, each item's value and priority, and the wave plan recorded in the umbrella's description. Adjust or re-scope before you sign off — your review shapes the entire batch. Approving the umbrella (the CEO's Approve & Start) releases the held root-subtasks so the dependency-gate dispatches them wave by wave, and the Main PM coordinates each root-subtask down to its cell.
