λambda — Learner-Adaptive, Marks-Bound Drilling Agent — is a study tool that keeps a working image of your mind: what you hold, where you stall, and which exam marks each gap is costing you. It probes before it teaches, teaches only what you missed, and drills until the fix survives a variant. The protocol is open source at lambda-agent; the hosted study lounge is being built at lambda.fatfort.com.

Signing in. The game icons drift, flee the cursor and collide; click one and it pops.

fat-fort is an early-stage effort in adversarial machine learning and computer-vision robustness — auditing where models break, and how to certify that they don’t. Built in the open, honest about the stage: no invented clients, no borrowed logos, no certifications that don’t exist yet.
The mark is a 2×2 grid whose corners read TT · TF · FT · FF. fat-fort is the FF corner (in red); its sibling tutorsfirst is the TF corner — two cells of the same matrix.
