Tutored, constrained build of Ruby web servers from raw sockets to C10K. Claude Code acts as a Socratic tutor: it quizzes you, reasons about your answers, and makes you type the load-bearing code yourself while it handles glue and review. Graded against a cgroup-constrained benchmark.

Tutored, constrained build of Ruby web servers through the PROCESS family only — from a raw TCP socket up to a Unicorn-like preforking server with heartbeats, graceful shutdown, and zero-downtime USR2 restart. Claude Code acts as a Socratic tutor: it teaches the mechanisms, makes you type the load-bearing code yourself, then quizzes you to consolidate once it's built and running — handling glue and review along the way. Verification is local and lightweight (nc, ps, lsof, kill -SIGNAL) — the emphasis is building and the signal protocol, not load testing. A focused pilot of c10k-dojo.

Lead-mode replicant: you lead an agent through database replication on top of SQLite in Ruby. The agent writes the ADR and the code — you make every decision, commit to numbers before the trial, review what it built, and answer for it. Hooks enforce decide-then-build and predict-then-measure.

Tutored, constrained build of a single-threaded reactor (event-loop) server in Ruby, from a blocking accept loop to a nonblocking IO.select reactor that juggles thousands of connections. Claude Code acts as a Socratic tutor: it quizzes you, reasons about your answers, and makes you type the load-bearing code yourself while it handles glue and review. Offline by design.

A tutored coding dojo: build database replication from scratch on top of SQLite in Ruby — leader/follower, a hand-written WAL, quorum and leader election — with a Socratic tutor that makes you type the load-bearing spine and an offline jail that keeps you honest.
