Module and layout files design, DCC-EX loco driving, takeover on the beam restore
- New design page: module, node and layout files; blocks with rail cuts,
sensors by running direction, geometry, a module editor later; top-view
SVGs of an example module, a standard 2E96 double-track module and a
district border on double track.
- DCC-EX Adapter §3.1: driving locos from the register.
- Takeover: the receiving node switches the transfer block when the beam at
its entrance is restored (the last car has passed) and the source edge
block is clear, instead of after a fixed delay; transfer blocks are cut in
both rails; on double track each district hosts the transfer block for its
incoming track.

Add LocoNet distributed master and transition zone design
New pages:
- LocoNet and the Distributed Master: throttle bus cabling rule,
distributed slot master, routing table, global power and short
reporting, fast clock, dashboard, LocoNet message reference from the
Personal Use Edition, stage 1 and 2 test setups, decisions D1-D10
and open questions L1-L11.
- Transition Zone Specification: catch-and-takeover handshake, state
machine, dual-coil latching relay driver, crash recovery, 2R/3R
interlocking, profile fields and open questions T1-T4.
The architecture spec links the new pages, adds the LocoNet actor,
exempts LocoNet throttles from the dead-man timeout and reorders the
roadmap with LocoNet as phase 4. Home gives an overview.
