regulator, a small but real Pi-based harness, built one checkpoint per lesson.

Extensions, tools, skills, sessions, compaction, model routing, SDK, RPC, packages and evals, each met as the answer to a failure.
A vocabulary that lasts
Variety, attenuation, amplification, feedback delay, authority, channel. Models move; regulatory structure does not.
