Real mathematics you can run: Bayes’ theorem, variational free energy, predictive coding and the POMDP machinery behind every UNI agent — each one an interactive laboratory, not a slideshow.

These labs are the practical half of a curriculum: the course is the syllabus they teach inside, and the hallway places them among the rest of the estate.
The laboratory’s own rooms, served whole from this site — 6 rooms and 25assets, every file an exact copy of a named path at a named commit, verified byte-for-byte on every build. The classroom is also the site’s front door.
The room you stand in: a photo-real laboratory with pixel-measured, hash-bound hotspots — the whiteboard, the specimen bench, the frequency wall and the mind-body wall.
the two viewer-API fetches fail closed into the page's own fallbacks; everything else — the room, the anchors, the specimens, the microscopy — is served from this site

the live model-registry fetch fails closed; the page's built-in content is served as committed

19c3064aba2ecc91 · docs/whiteboard/organism.html @ d73ba89cb419These 7 labs are copies of files from the public Workbench repository, pinned at commit c2c9c7246251. On every build of this site, each served copy is hashed and compared byte-for-byte against the same file at that pinned commit; a mismatch fails the build rather than shipping. That check is what ties the lab you run to the real code — the cite line under each card carries the hash so you can rerun the comparison yourself. (At the last read, the public repository’s head was the pinned commit itself.)
Bayes' theorem as a physical machine: prior chips pour through likelihood gates and what lands in the tray is the posterior.

These exist and are served from nowhere. They are printed rather than dropped, because a quietly shortened list is how an inventory starts lying.
not hosted state as declared: built, verified self-contained, not yet deployed
a Next.js application that does not yet set output:'export'; its 50 exhibits prerender cleanly and carry no external calls, but the repository has no public remote, so there is nothing a citation could resolve to yet
What would change this: a public repository plus a one-line static-export config
Wondering how this connects to the rest of the estate? The hallway has one door per project, and the course walks these labs in teaching order.
