Modsim 2.0.0a1 preview

Profile 0.2 TM/TD models now drive the simulator, using published modpoll-wot==0.2.0a1. A local deployment runs multiple isolated Unit IDs on one TCP listener. Models may be local or HTTPS URLs. Local scenarios support initial values, seeded generators and bindings; Python initialize/tick/on_write hooks require --allow-scripts.

The property codec covers integers, IEEE floats, strings, native/legacy booleans, byte/word orders, inverse multipliers and bit selectors. Partial writes validate overlapping properties and roll back on failure. Integer inverse transforms must be exact; constraints also apply after IEEE quantization.

Install: pip install modsim==2.0.0a1. Image: topmaker/modsim:2.0.0a1 (amd64/arm64). Documentation: https://top-maker.github.io/modsim/v2/. The repository and image include contrib ADAM models and examples/lab.sim.json. Models are manual-derived and synthetic-tested; no hardware certification is claimed. This preview leaves stable latest aliases unchanged.
