The L.A.B. Simulator · auto-graded labs

New: labs/ — Learn → Apply → Break. Ten labs across eight tracks with a CLI runner, a prerequisite DAG, and CI that grades solutions on a pull request. Runs offline; no AWS account.

If you are mid-curriculum: nothing moved. Labs are a parallel way in, not a replacement. Each links back to the module that teaches its concept.

---

The field guide · 77 reference pages

New: cheatsheets/ — 17 original frameworks, 10 API cheat sheets, 9 runbooks, 4 playbooks, 6 interview guides, 17 role-based how-tos.

Most useful if you are stuck: Failure Signature Catalog maps 16 observable symptoms to causes and fixes.

---

Discussions reorganised

Changed: every practice thread retitled, recategorised and tagged by track, level and format. Multi-hour labs and capstones moved from Exercises to Hands-on Labs.

If you had a bookmark: discussion numbers are unchanged, so every link still works. Only titles and categories moved.

New: an index of all 40+ practice threads, a discussion map, and answered Q&A.

---

Repository restructure

Changed, and this one breaks links: 118 flat root files became 16 topic modules under modules/. Any bookmark to a root-level file from before this will 404 — the curriculum index is where to re-find things.

Added: ~200 previously unpublished files, including every exercise solution, all of Agent Builder, the end-to-end production track, and the full ragkit retrieval library.

Also: all client branding removed, a real AWS account ID replaced with 123456789012, leaked local paths scrubbed, and CI added that blocks all three from returning.
