+# Aktuell: Gemeinsame Gruppenreisen implementiert
+
+Auftrag: Spieler- und Botgruppen mit sicheren Formationen, Reittieren, freiem
+Flug, nativen Taxis/Portalen und aufgezeichneten Verkehrsmitteln reisen lassen.
+Branch feature/clientless-player-core; Ausgangscommit a758239da9.
+Dieser Stand wird auf ausdrücklichen Nutzerauftrag lokal committet; kein Push.
+Doku: doc/clientless/group-travel.md.
+
+AdventureGroupTravelMgr/Policy übernimmt lokale Gruppenverfolgung, sichere
+Bodenpfade, stabile Formationsplätze, begrenzte Straßenabschnitte, Flugverfolgung
+und Übergangsqueues. >500Yards startet getrennte 10-Minuten-Uhr; bekannte Reisen
+und fortschreitendes Aufholen sind begrenzt geschützt. Reine Botgruppen behalten
+ihre gemeinsamen Graph-/Flugrouten. Native Transportverluste führen zum erfassten
+Einstieg zurück, zuerst per Pfad, bei Scheitern gezielt per Teleport. Keine
+allgemeinen Teleports zum Anführer. Generic CPC verwendet optionale owner-Callbacks,
+bleibt unabhängig von AdventureBots. DungeonBots unverändert.
+
+Build6 erfolgreich: /tmp/vcore-group-travel-build6.log. Alle82 Tests erfolgreich:
+/tmp/vcore-group-travel-tests2.log. Nach letzten Änderungen zusätzlich Gruppenreise,
+Straßenfortsetzung und bewegter Flug erneut erfolgreich getestet. Installation
+mit bestehender CMake-Konfiguration erfolgreich; vorheriger Server vollständig
+beendet. Neuer Start läuft: /tmp/vcore-group-travel-start1.log, PID183811,
+tmux vcore-worldserver. Startbereitschaft bestätigt: frische ready-Meldung, Prozess stabil, Port8085
+LISTEN. Loader24 online,10/2/10/2, pending0, error leer.
+Loader muss weiterhin aktiv mit10 persistent+2 temporär je Fraktion bleiben.
+
+Native Spielerreisen und visuelle Formation sind noch nicht im Spiel abgenommen.
+Unbekannte/scriptgesteuerte Portale oder fehlende Serviceaufzeichnungen werden
+nicht erraten; Bots warten bzw. suchen vorhandene Graphwege. Keine Behauptung,
+dass Adaptertests Gameplay-Abnahme ersetzen. Kein Push.

 # Aktuell: Klassen-/Rollen-Kampf und Spieler-Instanzmodus implementiert

+# AdventureBot group travel
+
+AdventureGroupTravelMgr is the common local-follow owner for player-led and
+bot-led groups. Bot-led macro travel retains the existing shared TravelGraph
+route and flight trail; DungeonBot CreatureAI remains independent.
+
+## Formation and ground safety
+
+Group members have stable GUID-ordered formation slots. Standing companions
+form a small staggered group. Moving companions form one, two or three columns
+according to checked walkable space; mounts increase spacing. Narrow/uncertain
+passages use one column. This estimates usable ground, not a semantic road width.
+Combat positioning and encounter avoidance retain priority.
+
+Local following uses complete, unsuspicious MMAP paths. Phased floor samples
+along paths reject holes, large height discontinuities and unsupported ground.
+The same owner-supplied validator runs before every clientless local spline,
+including graph approaches/repaths, while the bot is grouped. Dynamic LOS is
+checked for the actual segments. A rejected path stops following and is retried;
+it does not itself trigger a departure or a teleport.
+
+Recorded graph roads have an optional CPC GroundPathAdapter. The Adventure
+adapter checks bounded chunks, offsets safe lanes, falls back to single-file,
+and holds a row behind the moving leader. Edge point indices remain aligned;
+only an actually reached chunk endpoint advances the next road index. Native
+portal/boarding endpoints remain unshifted. Optional speculative road exits are
+disabled for adapted group roads so they cannot bypass the safety adapter.
+Ungrouped CPC navigation and unrelated scripts have no adapter by default.
+
+Mounted leaders cause capable profile-defined followers to use their own ground
+mounts even on short follow legs. Nearby followers dismount when the leader is
+on foot. Ordinary long ground catch-up can also use profile mounts.
+
+## Flight
+
+ClientlessFlightMgr::Follow adds a moving-target mode beside existing point
+flights. Native learned mounts/capabilities, area restrictions, casting and
+VMAP height/volume collision checks still decide whether flight is possible.
+Followers update their own formation target and fly bounded segments. Unknown
+terrain, blocked corridors or insufficient headroom cause a mounted hold.
+A moving aerial target is never treated as a ground touchdown.
+
+On landing, kick, leader change/loss or excessive separation, a tracking flight
+lands on verified local solid ground or uses its checked reverse trail. It never
+removes flight at an unverified height. Own group flights are serviced before
+self-care/combat actions can replace their movement; death handling still runs
+for dead characters. Daily-plan date refresh continues while airborne.
+
+Bot-led shared point flights preserve their native shared corridor and use
+staggered departures to form a single-file column. They finish a safe native
+flight leg rather than being cancelled in the air. Ground-only followers may
+follow safe projected ground points while the leader is no more than12 yards
+above them; greater height or missing ground paths makes them wait.
+
+## Known transitions and separation
+
+The leader is observed independently of a follower's self-care or current taxi/
+transport state. Taxi destinations use the final node of the native taxi queue.
+Ships, zeppelins and trams use recorded, matching native services. Fixed-destination
+SPELLCASTER GameObjects (including temporary portals with native DB destinations)
+and native AreaTrigger portals are recognized from the actual source and arrival.
+Bots approach and use the native handler/object; destination teleports are not
+fabricated. Per-follower queues retain consecutive transitions for late arrivals.
+Unknown/script-selected portals are not guessed; existing graph routes may still
+provide a valid way to the known destination.
+
+Player-led groups accumulate a separate10-minute timer beyond500 yards (3D,
+or separated maps/instances). Coming within500 yards resets it. A missing path
+alone never advances a special leave reason. Existing combat/death/instance/
+transport departure guards apply, and an airborne bot lands before leaving.
+Pure bot groups retain their previous late-rendezvous rules.
+
+Known actual journeys, own native taxi/transport travel and recorded transport
+recovery pause separation. Arrival has60 seconds of grace. Further catch-up stays
+protected only with route execution and recent physical progress; this does not
+extend unrelated later ground separation. Journey protection is bounded to30
+minutes. The ordinary AFK/hour-change departures are deferred during protected
+travel. No travel marker grants unlimited protection after a failed route.
+
+## Lost transport passengers
+
+ClientlessTransportMgr detects loss of an actually boarded recorded service.
+It retains the ride and attempts a complete, unsuspicious return path to that
+ride's recorded departure node. A missing/rejected/stuck path, cross-map loss,
+or a return that has not completed within60 seconds allows a targeted teleport
+to that same known safe entry point. It never teleports toward the leader or
+forward to the destination. The next service is boarded normally. Repeated losses
+are bounded; after three recoveries the ride terminates safely at departure.
+Ordinary death/resurrection remains owned by combat handling.
+
+Services require valid recorded boarding/alighting transitions and native graph
+connections. Missing service/portal data causes waiting or route failure rather
+than invented passenger attachment or a general catch-up teleport.
+
+## Diagnostics and validation
+
+`clientless interaction <guid>` reports formation travel ownership, separation
+milliseconds, protection, flight, queued transitions and route detail, alongside
+the existing group/interaction state.
+
+Automated tests exercise the production formation/ground validation, widths,
+mount choice, flight and kick landing, taxi grace, sequential portals, bounded
+separation, recorded-road adapters and native transport-loss return paths. Flight
+adapter tests exercise real corridor geometry and moving-target/landing decisions.
+Compilation and these adapters do not constitute visual in-game acceptance of
+player taxi, portal, flight or deck movement.
