A linear teach-from-zero tutorial that walks both SECS/GEM as a
protocol family and this codebase as an implementation. Each
chapter explains a SEMI concept and shows where it lives in code,
so a reader builds a mental model of the standards and the
repository simultaneously.
Structure (24 chapters across 5 parts):
- Part 1 (3 ch) — Foundations: what SECS/GEM is, the cast of
characters, vocabulary + a wafer's end-to-end journey
- Part 2 (10 ch) — Standards in detail: E5, E37, E4, E30,
E40+E94, E87, E90+E157, E116+E120+E39, E84, E42+E148+S9
- Part 3 (7 ch) — Codebase: repository tour, spec-as-data + codegen,
stores, transport, codec, state machines, persistence
- Part 4 (2 ch) — Operations: build/run/demo, integration
- Part 5 (2 ch) — Reference: API + messages + YAML, extension guide
Published in this commit:
- 00_index.md — guide layout, audience map, reading paths,
conventions, status table
- 01_what_is_secs_gem.md — the N×M integration problem, what SECS
vs. HSMS vs. GEM each actually refer to, the GEM 300 suite, the
transport→message→behaviour layering, where each layer lives in
this codebase, an end-to-end S2F17/F18 example
Chapters publish iteratively from here.
