Swap the factory's six tripService imports for the injected TripsService; delete services/tripService.ts and the collab/vacay bridges with it; prune the days/budget bridges to their surviving exports; update the migration docs and regenerate migration-graph.md.
- nest/README.md: reservations joins the DI-native list; recipe history gains
the residue-fold paragraph; next up is dayService per the dependency-honest
order.
- migrate.md: wave-4 entry ticked, with the migration-graph correction borne
out — reservationService imported neither budgetService nor dayService.
- migration-graph.md: regenerated for the post-fold import graph (row/node
removed, frontier and order updated, dayService is the next pick).
- plugins/DI-MIGRATION.md: the factory's last plain-function reservation
import is drained.
