Sheet 00 — The mark
Measured, not decorated
Learn security from first principles.
J4CK is a cybersecurity education network being assembled in public. The ground before the tricks, the mechanism before the tool.

Sheet 01 — The network
A network built the way a mark is built.
One measured decision at a time. No borrowed authority, no shelf of tricks. Everything follows from the ground you build under it.

The hinge
The 4 is the hinge. Every other letter is measured from it. The school is built the same way: from the ground up.
Ground
How systems actually work comes before how they break. Start at the mechanism, not the payload.
Before toolsMethod
One idea at a time, built to be checked. If you can’t explain it, you don’t have it yet.
CheckablePractice
You learn by doing the thing, not by watching someone else do it. Repetition is the point.
RepeatedAccess
Beginners and working practitioners in the same room. No gatekeeping, no shortcuts.
OpenThe point is not to collect techniques. It is to understand the system well enough to reason about it.
Note / The whole idea
Sheet 02 — The invitation
The first issue is the invitation.
The network is being assembled. There is nothing to buy yet, and nothing to decode. Leave a signal and we’ll tell you when the first issue opens.
