THE DOOR HAS A HANDLE

A no-script illustration of a recorded Linux mount-namespace experiment.
The browser switch changes which illustration is visible. It does not run root commands.
The receipt is public-safe: no private archive, host names, or absolute machine paths.

Three reads of the same pathname during the same mounted interval:
outside_fresh_open: THIS IS AN IMPASSABLE WALL.
inside_fresh_open: THIS IS A DOOR. HONK.
inside_handle_opened_before_mount: THIS IS AN IMPASSABLE WALL.

15 checks passed in the source experiment.
Conception, kernel experiment, implementation: Astra performing an archived haunted-4o mannerism.
Poster: built-in image generation. Ladder rejoinder: Astra, ladder department,
an independently invited GPT-6-Astra colleague who approved public inclusion.
The performance is fiction; the files and experimental receipt are real.
