EnigmaGrid 0.4.1 — Windows reliability fix

Recommended update for all Windows volunteers.

Fixed

Version 0.4.0 could stop its worker when Windows briefly locked the local status file during a read or antivirus inspection. The app restarted the worker and leases were recoverable, but ongoing work could be repeated. Atomic state writes now retry temporary locks and remove temporary files. A failed status-only write no longer aborts computation or network heartbeats. Credential and control writes still report persistent failures.

Checks

The regression suite reproduces a real Windows file-sharing lock, verifies recovery, and checks that persistent errors are not hidden for durable state. CPU/GPU resource and pause tests, security and HTTP tests, and the frozen client/installer pipeline also run for this release. Packages have GitHub provenance attestations, SHA-256 checksums and a signed update manifest.

The exact public installer was downloaded and hash-checked on a physical Surface with Intel Iris Plus. Upgrade preserved its existing identity and settings. During real CPU+GPU computation, 60 forced status-file locks caused no worker restart or unhandled exception; the same process recovered its health updates and completed a production job accepted by the coordinator (pending independent reproduction). Signed update success and intentional rollback passed against the exact release ZIP.

Help

Bug reports, installation questions and feature requests are welcome at https://github.com/LissomEnd/EnigmaGrid/issues/new/choose. See SUPPORT.md for troubleshooting. Never include credentials or unredacted personal data in public reports; use private security reporting for vulnerabilities.

Install and limitations

Download EnigmaGridSetup.exe and run it to install or update. Existing contributor identity and settings are preserved. The installer waits for the current job to finish. Volunteers do not need Python, administrator rights or Tailscale.

Windows x64. CPU and optional qualified OpenCL GPU computation. AMD integrated graphics and Intel Iris Plus have been physically tested; NVIDIA and all possible drivers are not guaranteed. The EXEs are not Authenticode-signed. Signed update metadata verifies origin/integrity, not absence of defects. Independent volunteer reproduction is required before final credit; a single contributor can accumulate pending work while verified progress remains zero.

The project is independent of Veritasium. No historical decryption has been confirmed.
