Adit-from-outside is a respectful sentence.

You do not lean in like a story. You lean in like a person reading a plaque. Thermometer falling. Echo delay still two-ish seconds, still a wall, still not an invitation. Radio: wind warning, Priya’s shovel, a weather station somewhere saying what you already feel in your teeth.

Folklore called this the mine breathing. You call it rock, ice, and a hallway that throws your voice home.

You can ride the knocks out under a roof, which is the correct choice in wind. You can photograph—or sketch—the ice-ping notes beside the grate, two kinds of sound agreeing to share a page, you never entering.

You add the echo-count beside the temperature like two friends who finally met. The plaque on the grate—CLOSED, BAD AIR, NO ENTRY—looks less like a spoiler and more like a gift. Silenced claims still have wind. Wind never signed the closure memo.
