/**
|
|
* Roster of people assignable to a train (ITLMS Rolling Stock §1.2 crew
|
|
* composition). Separate from freight.drivers, which registers road/last-mile
|
|
* truck drivers and shares none of these fields.
|
|
*
|
|
* Role and nationality are stored as varchar rather than PG enums so adding a
|
|
* crew role later is an application change, not a type migration. The partial
|
|
* unique index keys on name + role — the roster has no employee number yet, so
|
|
* that is the only identity available to block an accidental re-entry; it is
|
|
* scoped to live rows so a soft-deleted member does not hold the name hostage.
