The departure port needed a global binding that every suite building TripMembersModule without AppModule lacked. The roster's repository now deletes the leaver's row on the trip's journal link itself (leaveJournalLink), inside the transaction that removes the member: no edge into journey, no DI, no test stub, and the eight suites the stub touched are back as they were.
The schema inventory tests count the two new tables and their NOT NULL columns, the legacy step map lists the migration as post-legacy, and the TJL scenes give their users numbered names so cases sharing one database do not collide.
useTripJournalLink had grown past the 120-line limit for a function. The member list (candidates per journal, roles, who is new) is now useJournalMemberChoice. What loaded is kept with the journal it belongs to, so a new pick shows nothing until its own people are in, without resetting state by hand. The integration test adds its trip members with Promise.all.
A trip can now show one journal from the Journey addon as its own: any
journal its owner picks, and one journal on as many trips as they like.
The trip members chosen for the link get into the journal as viewers or
editors, see it in their own journal list and follow it live, for as long
as the link holds them and they stay on the trip.
That access is never copied into journey_contributors. It is read where
journal access is read: the contributor repository answers with the
stronger of a direct role and a link role, the journal list and the live
update recipients take the link members in, and the photo access check
goes the same way. Every one of those reads starts from linkReach, which
only counts members still on the linking trip, so unlinking, deselecting
someone and their leaving the trip all end exactly what the link gave.
A member who leaves is also taken off the link, so coming back later does
not quietly reopen the journal.
Linking or changing the members takes the journal's owner and the new
journal_link trip permission (trip owner by default); unlinking takes
either. /api/trips/:tripId/journal answers the link as each member may see
it, /candidates says who a journal would be opened to for the first time,
and four MCP tools do the same over the same service. A trip:journal:changed
event tells the trip to look again.
