The working paper: the whole method in one document
The foundational document: diagnosis, framework, minimum viable form, research agenda. Also available as PDF.
These are the canonical documents. The method pages summarize; the papers decide. Start with the working paper for the whole method in one document, or use the reading guide to pick a single topic.
Each deep dive covers one part of the method in full depth: the problem, the mechanism, the numbered rules, a worked example, known failure modes, and metrics. The rules run continuously from R1 to R36 across the series, and one worked example, an order-management system called Orderly, runs through all of them. Inside the papers the deep dives refer to each other by number (Paper 01 to Paper 09); the list below shows which number belongs to which topic. The working paper’s glossary remains canonical for the terms it defines; the site glossary is the complete current register, including terms introduced after the papers. One term also differs by register: the papers say increment where the method pages, tutorials, and kit say slice; the two words mean the same thing. Every document is also available as a file on the downloads page.

Which paper covers what, in which order to read them, and the running example that connects them.
Foundations and diagnosis: what waterfall actually is, what Royce actually wrote, and why SDD relapses.
Durable, ephemeral, derived: maintenance models and layered truth.
Amendments, semantic versioning, increment stamping, honest rollback.
Structure beats discipline: atomic PRs, executable criteria, one sitting one session.
The andon protocol and the drift pipeline: map and territory, kept aligned.
Three demo triggers, verdicts as artifacts, brains-eyes-hands, and the Goodhart anchor.
Per-layer authority, evidence-based movement, correlated verification failure.
Learning with amnesiac colleagues; refactoring the law; keeping humans competent validators.
Deep dive 09 (the craft of slicing): the unit of slicing, the sizing test, ordering by discovery value, the split catalog, and calibration.
