IAM lets an employee hold several positions, but the vendored JwtGuard
collapses employee.positions[] down to a single employee.position and
drops the rest. Non-delegate secondary positions vanished entirely, so
staff on two posts resolved to one post's permissions and every check
on the other rejected them.
FreightJwtGuard re-attaches the full list from the same session
snapshot the parent guard already read, so nothing extra is fetched
per request beyond a cached session lookup. employee.position is left
untouched, keeping audit logging and delegation unaffected.
collectPermissionKeys and collectPositionTypeKeys now union across
every position, and /me returns them all.
Verified against a real two-position user (djibouti-gl-director +
djibouti-gl-chief) on the local dev database:
/me positions 1 -> 2
/me permissionKeys 17 -> 28
GET /api/interchange-documents 403 -> 200
GET /api/trains 403 -> 200
11 permissions recovered, none lost. Six single-position users return
byte-identical payloads before and after.
