* refactor(server): route every trip-access check through DatabaseService
Twelve Nest services carry the same verifyTripAccess/canEdit pair. Six already
asked DatabaseService.canAccessTrip; the other six went through
services/tripAccess, a nine-line re-export of the identical function. Same
query, same result, two ways to reach it.
All twelve now take the injected route, so services/tripAccess is gone.
The bigger duplication was in the types. Thirteen files declared their own
`Trip` for the same return value, in three different shapes:
NonNullable<ReturnType<typeof verifyTripAccess>> 6x
{ user_id: number } 4x
TripAccess 3x
The narrow one is why assignments, days, places and accommodations all wrote
`as Trip | null | undefined` on the call — the cast existed to shrink
TripAccess down to a local type that was never meant to differ from it. All
thirteen now say TripAccess, and the four casts are gone with no other change.
middleware/tripAccess.ts goes too: it was already dead in production — nothing
under src/ imported requireTripAccess or requireTripOwner, only comments in the
services that had absorbed them. Its test went with it.
* refactor(server): fold the query helpers and trip joins into the container
Two more legacy files whose only reason for staying outside the container was
that they predated it.
services/queryHelpers.ts held five exports doing two different jobs. Three are
the batch loaders that keep the list endpoints off N+1 queries — they hit the
database and are now QueryHelpersService over the injected connection, imported
by assignments, days, places and share. The other two, formatAssignmentWithPlace
and ratingAggregate, touch no database at all; they sat next to the loaders only
because the loaders were free functions too. Those stay free functions, in
common/rowShape.ts.
The README note on the assignments service claimed the loaders had to stay in
services/ because the day, share and place services were unmigrated. All three
have since moved, so the reason is gone.
services/tripMembership.ts becomes TripMembershipService in its own module. It
could have folded into auth or trip-invite, but both call it — as do oidc and
the plugin RPC host — and putting it in either would have made AuthModule and
TripInviteModule import each other.
Neither module is @Global, matching PermissionsModule: e2e TestingModules
resolve them transitively through each consumer's explicit import.
Test seams changed shape accordingly. Two path mocks of services/tripMembership
became injected stubs; the trip-invite e2e overrides the provider in the
container instead. The oidc test keeps the real implementation, which is what
OIDC-SVC-045 was always asserting.
ratingAggregate moved out of the ungated services/ tree into the coverage-gated
one, so it gets the direct tests it never had — as does the tags/participants
pass-through, which two long-dead fixture variables in the moved test file had
been waiting for.
Also drops four stale comments that outlived their subject: the requireTripAccess
middleware they pointed at was deleted in the previous commit.
