Day 1 — Foundations & AI

By lunchtime today you will have logged in to the Yens, put your work under version control, built a reproducible Python environment, and written a script that sends a real SEC filing to a language model and validates what comes back. Tomorrow scales that same script across the cluster.

Part	Clock	What it delivers
Part 1 — Setup	9:00–10:30	Accounts, access and Claude Code — ending in a checkpoint
Part 2 — Python & AI	10:30–noon	Reproducible Python and API keys, ending in an LLM extraction checkpoint

Every section is written to be worked through yourself rather than followed along: the commands, the checks, and what to do when something goes wrong are all on the page.
