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.
Folds the legacy services/settingsService SQL into the Nest SettingsService
(byte-identical statements; BEGIN/COMMIT blocks become db.transaction()).
AdminService and ShareService inject it; llm-config.resolver becomes the
injectable LlmConfigResolver (SettingsService + DatabaseService), injected by
LlmParseService and PluginHostDepsFactory. No MCP surface, no bridge.
Whole-file commit, so this also carries the post-migration quirk fixes that
live in the same files: null serializes as '' (a stored "null" leaked out of
getDecryptedUserSetting as the literal string), bulk upserts skip the masked
sentinel (mirroring the single-upsert no-op) and return the written count.
Unit suite moved to tests/unit/nest with SET-SVC-001..026 preserved,
027..030 pin the fixes; settings/admin e2e converted to DI-native.
