generate_messages.py → gen_messages.py and several gem/ headers moved
under gem/store/ (carrier_store.hpp → store/carriers.hpp, etc.);
e84.hpp split into e84_state.hpp. The guided-tour chapters still
pointed at the old paths — relink them so the deep-link footnotes
resolve.

02 — The cast of characters: equipment, EAP, MES, fab planner, AMHS,
operator. Who initiates which conversation, why the equipment is
the passive side of HSMS by convention, how the AMHS handshake is
out-of-band relative to SECS. Cross-references the relevant
namespace and test files for each actor.
03 — Vocabulary + a wafer's journey: follows one 300 mm wafer
end-to-end through a fab and labels every SECS message and acronym
that fires. Introduces SVID / DVID / ECID / CEID / RPTID / ALID /
PPID / MDLN / SOFTREV / HCACK / ALCD / OFLACK / CAACK / SMACK / etc.
in context rather than as a list. Includes one-screen reference
tables for the remaining acknowledge codes, T-timers in all four
contexts (HSMS / SECS-I / E84 / E30 communication state), and a
stream-by-stream summary.
Part 1 (Foundations) of the guided tour is now complete — a reader
who reads chapters 01–03 can describe the protocol stack, identify
the actors, and recognise every acronym they'll meet in Part 2.
