CHANGELOG 0.1.4.md — Notepad

Added

• New POSIX syscalls and wrappers for fork, kill, raise, poll, select and fcntl(F_GETFL/F_SETFL) with O_NONBLOCK support.
• An automated runner .\build.ps1 smoke, which rebuilds, installs into /disk/bin, boots QEMU headless and validates fork, basic signals, polling and real persistence over SVFS2.
• A busybox multicall userland to start replacing the stopgap utilities, including echo, cat, ls, mkdir, rm, mv, cp, true, false and sleep.

Changed

• The system reports itself as v0.1.4 in the kernel, the shell, uname, sysinfo and the components consuming the shared version.
• The system's base timer is now calibrated targeting 200 Hz instead of 100 Hz, slightly improving perceived mouse response and the practical rounding of sleep_ms() for graphics and input loops.
• The internal ceilings go up for processes, descriptors, pipes, sockets, VFS and SVFS2, leaving more headroom for ports and a real userland.
• SVFS2 can now mount /disk in a degraded read-only mode if recovery does not leave the volume safe for RW, avoiding it going straight offline in the face of recoverable failures.
• The main build also installs the internal binaries in /disk/bin, so the shell and the automated smoke exercise the same persistent copy of the userland.
