server/src/nest/README.md drops from 988 lines to under 200: the module shape with weather as the reference, the cross-cutting pieces, the guards, parity and the test layout, without the bridge playbook and the services recipe that contradicted the code. The migration log moves verbatim to server/docs/nest-migration-history.md, marked historical. scripts/ci/doc-paths.mjs resolves every backtick path in the CLAUDE.md files, the root README, the blueprint and the wiki against the tracked files. The paths already missing are listed in a baseline that only shrinks, and the changes job runs it so docs-only changes are checked too. The wiki no longer says the Playwright flows stay out of CI.

Addons Overview
Addons are optional features that an admin can enable or disable for the entire TREK instance. When an addon is disabled, its navigation tabs, menu items, and API routes are hidden from all users.
What addons are
Each addon extends TREK with functionality beyond the core trip-planning features. Addons are managed globally: you cannot enable an addon for one user only. Once enabled, the feature becomes available to all users on the instance.
Addon list
The following addons are registered in the system (defined in server/src/db/seeders/AddonSeeder.ts; the TypeScript constant ADDON_IDS in server/src/addons.ts covers all addons except naver_list_import):
| Addon ID | Type | Description |
|---|---|---|
mcp |
integration | Exposes TREK data and actions through the Model Context Protocol for AI assistant integrations. |
packing |
trip | Lists: packing lists and to-do tasks for your trips. See Packing-Lists. |
budget |
trip | Costs: track and split trip expenses. See Budget-Tracking. |
documents |
trip | Document and file attachments for trips: itineraries, visa copies and other files. Can be kept in step with a self-hosted document store (Paperless-ngx, Papra, Nextcloud, OpenCloud, Synology). See Documents-and-Files and Document-Sync. |
vacay |
global | Personal vacation day planner with a year calendar, holiday packs, collaborator fusion, and read-only calendar sharing. See Vacay. |
atlas |
global | Interactive world map showing countries and regions you have visited, plus a bucket list. See Atlas. |

roadtrip |
trip | Road trip: plans a trip as one continuous drive, with stops along the route, driving times and arrival times that update themselves. Off by default. See Road-Trip. |
journey |
global | Trip tracking and travel journal: check-ins, photos, and daily stories. See Journey-Journal. |

llm_parsing |
integration | AI Parsing: an LLM fallback that extracts bookings from confirmation files KDE Itinerary can't read. With a model that reads images it also takes photos and scanned PDFs, and Costs gets Scan receipt. See AI-Booking-Import and Budget-Tracking. |
naver_list_import |
integration | Import places from shared Naver Maps lists directly into a trip. |
Enabling addons
Admin: all addons are toggled from the admin panel. Navigate to Admin-Addons to enable or disable individual addons for your instance.
Per-addon sub-features
Some addons expose sub-features that an admin can independently toggle. The Real-Time-Collaboration addon, for example, lets an admin decide which of its five sub-features (chat, notes, links, polls, and what's next) are active across the instance. These are configured from the Admin-Addons panel alongside the addon's main toggle.
The Documents addon carries one switch per document store: Paperless-ngx, Papra, Nextcloud, OpenCloud and Synology Drive. They are off by default and only show while Documents is on, and switching Documents off switches all of them off. The stores themselves are connected per trip, in the trip's file manager. See Document-Sync.
