Codifying learnings — instruction files, solution docs, the compound step

The mechanism that makes compounding real rather than aspirational. After each cycle
the team captures what worked as durable, retrievable knowledge: short always-true
conventions go into the agent's session-level instruction file (CLAUDE.md /
AGENTS.md), and solved problems are written as searchable documents — tagged with
frontmatter and filed by category — that future sessions find automatically.
Students learn the discipline of the compound step (extract the reusable insight,
make it findable, update the system, then verify the system would now catch the
issue next time) and how it connects directly to the memory taxonomy of EB-5 and the
harness instruction files of EB-2.
