KERNEL PANIC 4.0.0
Released 2026-10-19.
The system crashed. You didn't.
Release scope
- Offline arcade Endless, Story and local Weekly play.
- First-class controller navigation and a touch-native Mobile interface.
- Large-text and accessibility options, localized player copy and safer Mobile layouts.
- Deterministic replay/Watch checks, save migration/recovery and separate Player/Contributor builds.
- Optional Linux Discord Rich Presence, off by default.
The accepted 4.0 soundtrack delivery retains 38 authored WAV stems. Hybrid Ogg/WAV conversion and advanced phrase/synchronization polish are deferred to 4.1; no completed conversion or seam qualification is claimed.
Official public rankings, server-backed submissions, downloadable ghosts, the canonical online update/manifest pipeline and Chaos are not part of this offline 4.0 release. Halloween content is not included in Player packages.
Legacy optional desktop clients remain: an update-version check (off by default, no binary download or replacement) and a user-configured board endpoint (off by default, no official server configured). Explicit board submission sends the selected name and recorded run to that endpoint; plain HTTP endpoints are not confidential. These optional clients are not an official 4.0 ranked service or automatic updater.
Platforms
- Linux x86_64: portable tarball, AppImage and Debian package. Native artifact and automated runtime checks passed.
- Android arm64: signed Player APK, Android 8.0/API 26 or newer, touch-device evidence. Android controllers are not verified.
- Windows x86_64: release build under the Experimental / Best Effort support tier. A standalone
.exe, a documentation ZIP and an optional per-user setup wizard are provided. Wine evidence is not native Windows validation, Windows Rich Presence transport is unavailable, and the setup is unsigned so SmartScreen may warn.
All Player binaries are release exports, not debug builds. Contributor packages are development builds and cannot submit competitive runs.
Verification and limitations
The exact offline source candidate passed 111 closure gates, including 9614 Desktop assertions with zero failures, eight explicit skips and no script errors or shutdown leaks. The physical Android Player update from 3.2 to 4.0 preserved the original installation identity and every original progression field; the owner confirmed touch gameplay, pause/resume, death/restart, navigation and audio. A bounded runtime log capture observed no script error or fatal exception.
The old Contributor harness reported one freed-instance script error in its enemy-death idempotency test; that is retained in the evidence and is absent from Player builds. Earlier diagnostic runs had intermittent UI failures/native crashes whose cause was not established; the final exact-tree run passed. The final run warned that a connected gamepad could interfere with synthetic input.
Windows real-machine testing and Android controller testing were not performed. No universal readability, performance or Android-version guarantee is claimed. Save data lives outside the executable/install directory; replacing a binary keeps it. Do not uninstall or clear application data to resolve a signing mismatch. The optional setup is unsigned.
