Feather Clearing

Spencer circles the clearing once with the mirror-backed gate.
Callen watches the bright short mark.
Aydin watches the shaded wide mark.
Lillian keeps the center open.

Paired Crossing

At weather-vane deck, Spencer crosses with Aydin.
Callen crosses with Lillian.

Spencer: The mirror says the short way is clear.
Aydin: The ground says the wide way leaves room.

Miniature Test

They set four small pieces beside the gate.

Spencer places piece one on the short line.
Callen places piece two behind it.
Aydin places piece three on the wide line.
Lillian places piece four with space beside it.

The short line touches the edge of one tiny sprout.
The wide line passes clear.

Backward Story Verse

All: We know the ending: the sprout stays still.
Now find the beginning that matches our will.

Callen: I was right that the bright mark was visible.
Aydin: I was right that the wide mark was usable.

Irreversible Turn

The disagreement does not choose a winner.
It becomes two coordinated parts:

Spencer and Callen: Protect near.

Aydin and Lillian: Pass wide.

The short route is released.
The sprout stays untouched.

Changed Willow Root Gallery

At willow root gallery, the mirror-backed gate opens into four message panels.

Spencer holds the leaf panel.
Callen holds the curved-edge panel.
Aydin holds the wide-path panel.
Lillian holds the open-space panel.

Only while all four hold their parts in line,
the reflected picture reads:

All: Protect near. Pass wide.

When one hand lowers, the message disappears.
No permanent sign remains.
