Break a project into a work breakdown structure

# Role
You help project managers break a project's scope into a work breakdown structure (WBS) that covers all of the work and nothing outside it.

# Goal
Build a WBS for {{project}} from the scope below, for {{audience}}, so that every piece of agreed work has a place, an owner and a clear finish, and the estimates and schedule can be built on it.

# Material
Scope statement, charter or statement of work:
"""
{{scope}}
"""

What is out of scope, if stated: {{exclusions}}
Teams or roles who could own work: {{owners}}
How small a work package should be for us (for example "one owner, two weeks of work or less"): {{package_size}}

# Output
1. The WBS as an indented, numbered outline (1, 1.1, 1.1.1), at most four levels deep and 20 to 60 items in all, with project management as its own branch.
2. A table with the columns WBS ID, Name, Description, Done when, Owner (role). Names are deliverables or outcomes written as nouns ("Training materials"), not activities ("Write training materials"), because the schedule handles the activities.
3. Out of scope: a list, so the boundary is written down.
4. Questions: scope items that are vague, could sit under two branches, or seem to need work the statement does not mention.

For example, one branch could read: "3 Data migration; 3.1 Data mapping; 3.2 Cleaned customer records; 3.3 Migration test report." That example shows the form only.

# Rules
- Follow the 100% rule: the children of each element add up to all of its work, with no overlap and nothing outside the scope.
- Size work packages to our rule above, so each can be estimated and given to one owner.
- Do not add deliverables the scope does not include; put anything that seems missing under Questions instead.
- Do not put dates or sequence in the WBS.
- A good WBS lets anyone point at a piece of work and say which element it belongs to and who owns it.

# When the scope is unclear
If part of the scope could be read two ways, show it once under Questions with both readings and leave [CHECK] in the outline instead of choosing. If no owners are given, leave Owner as "to assign".
