* feat: emit logos_module_dispatch_async for concurrency:multi C++ modules The cdylib C-ABI exports gain an async dispatch entry (each call run on a worker thread, reply on completion) for universal + cdylib C++ modules. --concurrency multi flag in logos-cpp-generator. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * docs: cpp-sdk concurrent-dispatch doctest (concurrency:"multi" showcase) A concurrency:multi C++ worker + a single driver firing concurrent calls, showing the multi worker overlaps them. The C++ cdylib generator needs NO change — its logos_module_dispatch is already safe to call concurrently; the worker pool lives in the Qt glue and the result is deferred via a sentinel + completion event. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix: wire universal-cdylib modules() independent of the context latch A C++ interface:"universal" cdylib that calls another module via modules().<dep>... segfaulted on its FIRST cross-module call: the typed dependency surface (LogosModules) was wired inside lidlTryFireContext, which returns early when no persistence context was stored (g_ctxStored == false). When the daemon never delivers a context (observed: zero set_context calls for a context-less module), maybeSetLogosModules never ran, m_logosModulesPtr stayed null, and LogosModuleContext::modules() dereferenced null. modules() does not need the context — each dependency client bakes its target+origin at codegen time and creates its lp client lazily on first call. So wire it in its own context-independent once-latch (lidlEnsureModulesWired), called at the top of lidlTryFireContext before the context-gated early return, i.e. on the first dispatch / set_context / set_emit_callback. A module with deps but no stored context now has modules() wired before any handler runs. (Bump the concurrent-dispatch doctest's post-daemon-start sleep 3 -> 6 to match the rust spec's cold-start margin.) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test: green the universal-cdylib concurrent-dispatch doctest + wire into CI The driver/worker split a declarations-only impl header (so the cpp-generator's --header-to-lidl doesn't choke on inline std calls) from the impl body. That body was never compiled — metadata's nix.cmake.extra_sources is parsed but not consumed by the LogosModule.cmake the build actually uses — so the impl symbols (FanoutDriverModuleImpl::fanOut / ::peak) were UNDEFINED in the dylib and the plugin null-jumped (bl -> 0x0) on the first cross-module call. Pass the impl .cpp via logos_module()'s existing SOURCES argument so it's compiled and linked. With this the cpp universal-cdylib reaches worker peak overlap 4 end-to-end (a single-threaded driver fans out 4 async calls into a concurrency:"multi" worker and all four overlap), matching the Rust half. Wire the spec into doctests.yml so the workspace pipeline runs it. (Auto-wiring metadata.extra_sources — so the split pattern works without listing SOURCES by hand — needs the consumer added to the backend LogosModule.cmake copies in logos-plugin-core / logos-plugin-qt; tracked separately.)
