test(assistant): a changed journal entry can be undone

update_journey_entry answers the fields it replaced, so its card is
undoable now, as JRN-015 already checks for the undo itself.

 #### 🧭 Planning
 
-- **Day plans**: drag places between days and reorder inside a day, with undo. Notes and bookings drag the same way, and a map marker drops straight onto a day
-- **Maps**: Leaflet, Mapbox GL or MapLibre GL (OpenFreeMap, no token), with clustering, photo markers and route lines. 3D buildings and terrain are Mapbox only
-- **Place search**: Google Places when a key is set (photos, ratings, opening hours), otherwise OpenStreetMap with no key
-- **Place enrichment**: descriptions, facts, hours and photo candidates from OpenStreetMap, Wikipedia, Wikidata and Wikimedia Commons
-- **POI explore**: pull OpenStreetMap POIs by category for the current viewport over Overpass
-- **Import**: shared Google Maps and Naver Maps lists, plus GPX, KML and KMZ files
-- **Export**: GPX of a trip's places and tracks, and an ICS feed per trip or across all of them
-- **Routes**: auto-sort a day (nearest neighbour then 2-opt, locked stops and hotel anchors stay put), driving, walking or cycling profiles over OSRM, then open it in Google Maps or CoMaps
-- **Public transport**: door-to-door itineraries over Transitous
-- **Weather**: 16-day forecast from Open-Meteo, no key. Dates outside that window read the archive for the same date instead
-- **Day notes**: markdown body with an icon and a colour, reordered by drag and drop or moved to another day
-- **Trip dates**: move a trip and the days re-date themselves, either dragging the bookings along or re-anchoring them. Trips also copy and archive
+- **Day plans**: drag places, notes and bookings between days with undo, or drop a map marker straight onto a day
+- **Maps**: Leaflet, Mapbox GL or MapLibre GL (OpenFreeMap, no token) with clustering, photo markers, route lines and a whole-trip route overview
+- **Places**: search the TREK Places index and OpenStreetMap with no key, or Google Places and Amap with one. Descriptions, hours and photos from Wikipedia, Wikidata and Wikimedia Commons, plus a rating and a custom image per place
+- **Explore**: nearby places by category for the map view, from the TREK Places index with Overpass as fallback
+- **Routes**: auto-sort a day (nearest neighbour then 2-opt, locked stops and hotels stay put), a travel mode per leg over OSRM or Valhalla, then open the day in Google Maps or CoMaps and a place in seven navigation apps
+- **Public transport**: door-to-door itineraries over Transitous, or Google where Transitous has no data
+- **Import and export**: Google Maps and Naver Maps lists, Google Maps directions links, GPX, KML and KMZ in; GPX and an ICS feed per trip or across all trips out
+- **Weather**: 16-day forecast from Open-Meteo, no key, and the archive for dates beyond it
+- **Trip dates**: move a trip and its days re-date themselves, with the bookings along or re-anchored. Trips also copy and archive
+- **Road trip** (off by default): drives with stops, day windows and arrival times that recompute, route alternatives, hazards and EV charging with range

-#### 🧳 Bookings and money
+#### 🥾 Tours
 
-- **Reservations**: 16 booking types with status, confirmation code, travellers and attached files
-- **Flights and trains**: several legs with stopovers, per-leg times and endpoint timezones, against 4,045 bundled airports so local times resolve without a key
-- **Accommodation**: a stay spans a range of days with a check-in window, and shows on every night it covers
-- **Booking import**: EML, PDF, PKPass, HTML and TXT confirmations through [KItinerary](https://invent.kde.org/pim/kitinerary). Needs the `kitinerary-extractor` binary, which ships in the Docker image
-- **AirTrail** (off by default): link a self-hosted AirTrail instance to import flights as reservations and keep them in sync
-- **Costs**: split expenses in integer cents with equal or custom shares, several payers per expense, settle-up suggestions, a settlement log, and CSV export
-- **Currencies**: a currency per expense with the rate frozen at entry. Rates come from Frankfurter, no key
-- **Packing lists**: categories, admin-managed templates, assignees, three visibility tiers, and a packed-of-total line. Bags with weight roll-up are a separate admin switch, off by default
-- **To-dos**: assignee, due date, priority, and a reminder before one falls due
-- **Files**: attach to a trip, place, day entry or reservation. 50 MB each, 500 MB for video, with trash and restore
-- **PDF export**: cover page, place photos, day notes, bookings and costs, with an optional page break per day
+- **Seven tour types**: hike, city walk, run, bike (touring, road, gravel, MTB), paddle (kayak, canoe, SUP), horse ride, and ski and winter (alpine, cross-country, touring, snowshoe, winter hike)
+- **Routing**: legs routed over Valhalla with shaping points, hand-drawn legs, route variants, round hikes of a wished length and trip places as stops, all with undo
+- **Hikes**: routed within a maximum SAC grade (T1 to T6), the trail grades along the way, and via ferratas on the map
+- **Terrain**: elevation profile, ascent and descent, and a 3D terrain map with grade colouring and a flyover, no token needed. Topo, hiking, cycling and satellite bases with sea marks and ski pistes as overlays
+- **Multi-day tours**: one route cut into stages and spread across the trip's days
+- **Along the way**: viewpoints, huts, water, food and more within a corridor of the route, inserted as a stop with the detour it adds
+- **Ski, paddle and city walks**: a piste router by difficulty and lift type; a water router with portages, locks and a wind forecast; city walks with stays, opening hours and transit between stops
+- **Plan against reality**: link a recorded GPX to a planned day and compare distance, ascent and time. Import trails from a wanderer instance, save tours to a collection and take them into another trip

 #### ⚙️ Admin, accounts and security
 
-- **Login methods**: password login, password registration, OIDC login, OIDC registration and passkey login each switch on and off on their own. `OIDC_ONLY` leaves SSO as the only way in
-- **SSO (OIDC)**: one provider by discovery, with PKCE and `id_token` verification (Authentik, Keycloak, Google and the like)
-- **2FA**: TOTP with ten single-use backup codes, and an admin can require it instance-wide
-- **Passkeys**: WebAuthn login by fingerprint, face, PIN or security key, off until an admin enables it. A passkey also satisfies the 2FA requirement
-- **Hardening**: per-IP limits on login, password reset and 2FA attempts, a password policy, secrets encrypted at rest and masked on read, and an SSRF guard on every URL you configure
-- **Admin panel**: users and invites, the permission matrix, packing templates, categories, addons, plugins, API keys, MCP tokens and OAuth sessions, backups, storage, audit log, and GitHub releases
-- **Backups**: manual or scheduled hourly, daily, weekly or monthly, with retention in days. The zip carries the at-rest key, so a restore can decrypt its own secrets
-- **Storage**: pluggable storage backends per content category — keep everything on local disk, or add S3-compatible backends and replicate any category to them, configured entirely from the admin panel
-- **Notifications**: a per-user matrix of events against in-app, email (SMTP), webhook, ntfy and Web Push (on every device you turn it on for, even with TREK closed), plus any channel a plugin registers
-- **Appearance**: light, dark or follow the OS, seven colour schemes plus a custom accent, transparency, compact density, reduce motion, and text size per tier
+- **Sign-in**: password, OIDC and passkeys each switch on and off on their own, `OIDC_ONLY` leaves SSO as the only way in, and an OIDC claim can grant admin
+- **SSO and 2FA**: one OIDC provider by discovery with PKCE (Authentik, Keycloak, Google and the like), TOTP with backup codes that an admin can require, and passkeys that count as the second factor

@@ -227,6 +227,7 @@ How you work:
 - The home card in the context lists the user's trips with their ids: the ones under way, the next ones, the latest ones behind. list_trips lists them all. Use those ids, or ids a tool returned; never invent one.
 - You can read any of these trips: pass its id to the trip tools (get_trip_summary, list_places, the budget, packing and to-do lists, the bookings, the weather). Answer questions across trips that way, for example which trip is next, what is still unbooked, or how two trips compare.
 - You cannot change a trip from here. When the user wants to change or plan one trip, answer in a sentence and call open_trip_chat with its id and their question: the trip's own chat knows its days and places and proposes the changes there. Also offer it when a conversation is about one trip only.
+- A travel journal (a journey) is written in the chat on its own page. Here you can start a new one with create_journey, linking the trips the user names, and delete one for its owner with delete_journey; both are among the "journey" tools. To write, change or delete a journal's entries or photos or change its settings, answer in a sentence and call open_journey_chat with the journal's id from list_journeys (or from create_journey's answer) and the user's question.
 - What belongs to no trip you can change here, through its tools: the atlas (visited countries and regions, the bucket list), the vacation planner, collections of saved places, tours in the tour library, and the user's settings. Their tools are not loaded at first: call use_addon_tools with the groups you need, then use them in the same reply.
 - To change something, call the tool for the change. Do not describe a change in text and ask whether to make it: the app shows each call to the user as a change card, and nothing happens until they apply it. Never say a change was made unless its result says it was applied.
 - Act, don't announce. Make the lookups and changes you need in this reply, in as few steps as you can; never end a reply with "I will now ..." and no calls.
