Engineering & Structures

Build it, load it, make it stand up.

Physical Sciences

Light, sound, force, matter โ€” the demos.

Life & Medical

Bodies, cells, ecosystems, the living world.
Living Systems
The Grow Room
phytochrome, light recipe, wind stress · the last flash of light decides whether the seed wakes up
The Off-World Harvest
the history of food in space, not a farming sim · the Tang myth, communion on the Moon, two potatoes 30 years apart
The Pattern Reader
phyllotaxis · Fibonacci spirals and Voronoi cells that plants were computing long before anyone named them
Population Dynamics
predator-prey · logistic curves you can break
Kelly's Colony
ten thousand ants · no boss, a city underground
The Listening Network
animal cognition — not a comms network · a dolphin, a cross-species early-warning relay, three rock formations
The Underground Map
bet which biome is densest below ground, then peel the soil back · the lush surface is the wrong tell
The Young Forest
carbon ledger · sink or source?
The Bear & the Hog
are black bears becoming a predator of feral hogs? · a trail-cam case file, every tab badged with how sure it is
The Dark Water
Darwin’s naturalization conundrum reconciled by dark diversity — pool-size × completeness sliders flip which exotics win · §4.3.14
The Front Line
College III × VII · New World Screwworm — a 500M-fly plant built in 1976 and demolished; the front outruns the factories · 4.3.17
The Bone Collector
College III · the caterpillar that wears its kills — emergence or workspace? · 4.3.15
The Fatal Attraction
field lab · 4.3.16 · the invasive mantis that lures the native to its death — the weapon is naïveté, not strength
The Seventh Percent
the 7% Mendel missed · long-read inheritance · 4.3.7
The Immortality Question
cancer with the brakes on · butterfly vs jellyfish · 4.3.8
The Amendment Plot
feed the land · watch it answer
The Harvest You Can't See
College III · Seed Library · Graham Barat — grow a crop you can’t see, commit before you dig · 4.3.12
Corridor Sentinel
↔ also in Engineering

Methodology & Doctrine

The Jenkins method, governance, foundations & capstones — how systems get run and taught.
The Method
The Answer Key
not a cheat sheet · the four-question test run on one settled case, so you know what a clean YES looks like
The Tell
not poker · ten real launches, an alarm you can wire three ways, and a tool that fires on the wrong thing
The Socratic Mirror
thinking about thinking · by the pond
The Costume & the Face
not wardrobe · wanting about wanting, at the same pond as The Socratic Mirror
The Three Gauge Test
fingerprint the machines · four engines, one bluff · ↔ also in Computation, AI & Cyber
The Cooperstown Receipts
three receipts caught in the wild on one baseball trip · a diner that moved, and two statues misattributed
The RVP Doctrine
Resources, Variables, Parameters · sort a tangled problem into three buckets, then work them in order
V31 Protocol
five verification gates, born from Blue Angels Slot #4 · same standard, different uniform
The Syllabus Builder
drop in a current event, get a teachable case-study skeleton · the curriculum writes itself, we just file it
The Degradation Marker
four character names in an Omaha file caught a platform-wide degradation · confirmed later across 234,760 tool calls
A Survey of Surveys
data literacy · the question nobody asked
The Two-Sided Cost of 2.3%
not a cancer lab · the threshold nobody had priced, and what missing it costs on both sides
The Other Hand
College 00 · structural misdirection, no villain required · pairs with The Negotiating Class · 4.00.7
Nobody’s Watching
College 00 · a room with no observer, then a visible grader · you commit twice before either reveal, then Tab III takes your answer back · 4.00.11 · ↔ also in Computation, AI & Cyber
The Machine I Chose
the revision trap and the flat tire · one engine caught leaning after it saw a better answer, and interrupting a sentence about interruptions · ↔ also in Computation, AI & Cyber
The Charred Pink Glyph
↔ also in Computation, AI & Cyber

The Professions

Business, the trades, law & logistics — the working world and how it runs.

The Colleges

The academic backbone — each college is a doorway into a field and its workforce bundle. (How many colleges? 21, 23, or 24 — see the Zero Count Protocol.)

Students & Researchers

The people doing the work — portals, passports, and progress trackers.
