LTSv3 POSIX Roadmap Update
summary
LTSv3 targets a concrete POSIX implementation with an LTS release date of July 26 and measurable progress: test suite grows by about 1,000 lines, Kconfig cleanup and option-group mapping are underway, and conformance checks for PSE51/PSE52/PSE53 are in progress. Missing items include map files and memory protection and virtual memory paging; signals and real-time signals are being implemented with pthread_kill nearing completion; networking and file-descriptor features are present; builds test against newlib pico libc native libc.
