Three fixed-light stations: camp departure, sheltered hollow, river approach. The real river lies east. A complete night route requires all three stations; otherwise travellers wait at camp. Beacon service cord lowers the mirror to the stair. Try this: Budget lantern counters and compare a walking route with a fixed beacon.
River line: remains visible when the beacon turns away; runs east beyond the trees. Leaf line: appears only under the turning mirror. Draw an arrow from the tower toward the line that stays. Try this: Choose the bearing from observed landscape, not from the moving beam.
Beam over leaves: wings circle. Beam away: wings settle. During the settled interval, two people can reach the inside rail without passing under the flock. Mark one watcher and one hinge worker. Try this: Plan the quiet platform approach and assign two roles.
Scarf-coloured ribbons: cache → short wooded rise → beacon stair. The trail needs three lanterns. Count the lamps actually in the box; a lamp still with a patrol cannot be used here. Hooks on the ranger chart match the three symbols on the box lid. Try this: Add the discovered shortcut to the map and place each lantern on a station.
