Plan proposals live in the conversation (plan-approval flow); items are created open/unassigned and work starts at assignment — the granted, revocable authority. Also closes a verify gap: tail truncation is now caught against the stored head hash.

"""Work-item model for agent teams — states, actors, links, errors.

|
The board is not a database of record: it is a projection of the append-only team
|
|
event log (see teams.store). These are the shapes the projection folds into, and the
|
|
rules the verbs enforce. Deliberately minimal — no sprints, estimates, priorities, or
|
|
custom fields; anyone needing those graduates to a real tracker via connectors.
