JefeRust 1.0.0 — the second kernel reaches its baseline

Release boundary

Parity with a frozen target, not a moving one

The 1.0 contract is the 55-line feature inventory frozen at the C++ v1.0.0 tag. All 55 lines are implemented in JefeRust. Newer JefeOS features—including its 1.1.x OpenStack and Xylem workload-supervision work—belong to the separate C++ release lane and are not claimed here.

What ships

A native Rust x86_64 kernel with its own scheduler, memory manager, drivers, filesystems, networking, cryptography, GUI, shell, and Linux/POSIX compatibility path.
Full read/write NTFS support across resident and non-resident data, fragmented allocation, directory-index growth and collapse, and bounded metadata mutation paths.
Kernel support for selected native and Linux-compatible userspace, including the separately deployed Node-based Discord workload exercised on the golden image.
A sanitized copy of that bot's generic userspace logic, supplied as a separate ZIP for inspection and experimentation; it is not embedded in the ISO.

Exact-revision evidence

The image and the proof share one identity

Titan clean build: 11/11 release tests, 8/8 release-mutation checks, and 9/9 KVM/QEMU checks.
Host policy gates: 533 passes plus 11 named policy skips out of 544 accounted tests; zero unaccounted failures.
Independent runtime checks: Windows QEMU passed 9/9, and two consecutive Hyper-V runs each passed 219 tests with the same five named compatibility skips.
Golden workload: separate operational Discord status captures reported the same image boot and bot PID as reported uptime advanced past seven hours; commands succeeded, and each captured status reported READY with matched heartbeat counters. The formal machine-readable two-hour collector gate remained NOT-RUN and was explicitly waived by the release owner; these observations are not reported as a machine PASS.

Honest framing

This is a kernel release, not a Linux distribution

JefeRust runs selected native and Linux-ABI userspace, but does not claim complete Linux or POSIX compatibility, supported-default SMP, production hardening, or parity with current JefeOS master. The source repository remains private. The ISO is a runnable research release.
