A person may be able to work as guide, assistant, or both, but every booking team must say which one they are doing now.

Role eligibility defines the slots where a person may be selected. A booking-team assignment then records one explicit role without changing eligibility or rewriting completed history.
A person is added, edited, or selected for a booking team.
Eligibility describes capability across future staffing choices.
Only eligible people appear for each role.
This is the key moment: assignment records what the person is doing now, not everything they may do.
Dual eligibility never becomes two roles in the same team.
Changing future eligibility does not rewrite completed assignment history.
Records eligibility and selects a role for a specific team.
Keeps role eligibility separate from current commitment.
Sees the role held in the actual assignment.
Filters slots and prevents one person from holding both roles in one team.
Eligibility flags and role-specific team slots
Why: Select a valid role without confusing capability with commitment.
Guide or assistant on the actual mobile assignment
Why: Know which role applies to this work.
Eligibility says what a person may do; assignment says the one role they hold on this team.
