Extract the SECS/GEM engine wiring out of the secs_server app into a reusable class, and stand up a language-agnostic gRPC daemon on top so a tool's software (any language) can drive the equipment without linking C++ or knowing SEMI. Foundation for replacing a vendor's SECS/GEM server. Engine reuse: - EquipmentRuntime (include/secsgem/gem/runtime.hpp, src/gem/runtime.cpp): owns io_context, passive Server, model, control-state machine, Router; thread-safe outbound API (set_variable/emit_event/set_alarm/clear_alarm), on_command hook, deliver_or_spool, run()/run_async()/poll()/stop(). - register_default_handlers (src/gem/default_handlers.cpp): the 56 GEM handlers + domain emitters, relocated from secs_server so the app and the daemon speak byte-identical GEM. secs_server.cpp reduced ~1270 -> 113 lines. - name_index.hpp: resolve_variable(name) -> VID (the name->id binding layer). Daemon (apps/secs_gemd.cpp, proto/secsgem/v1/equipment.proto): - runs the engine + HSMS link on a background thread; serves the gRPC Equipment service. Increment 1: SetVariables (name-resolved, plain value->Item) and GetControlState. proto carries the full v1 surface (universal + carrier/recipe/job tiers); remaining RPCs + the Subscribe command stream are next (docs/DAEMON_ROADMAP.md). - CMake: opt-in SECSGEM_DAEMON, protoc/grpc_cpp_plugin codegen, gracefully skipped where protobuf/grpc++ are absent. Dockerfile gains the grpc deps. Tests (proof): test_runtime, test_default_handlers (S1F1->S1F2, S2F41->hook), test_name_index. Full suite 458/458, 2795 assertions; live server<->client GEM300 demo still passes on the refactored server. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
