Verathos v0.2.1 – Sleipnir Cross-Machine Serving

Verathos v0.2.1 – Sleipnir Cross-Machine Serving

Sleipnir gains improvements for deploying and operating model stages across
independent machines.

• More reliable cross-machine deployment, automatic context calibration, and
  verified startup readiness.
• Distributed hard proofs retrieve authenticated weight data for the relevant
  stages without requiring every worker to store the complete model file.
• Improved worker joining, delegated signing connectivity, and restart
  readiness across distributed and single-machine placements.
• verathos --version and startup banners identify the installed code release
  separately from automatic-update thresholds.

Optional update

v0.2.1 is optional. Existing v0.2.0 installations remain compatible and will
not automatically update or restart for this release. Mesh operators can
opt in to receive the cross-machine fixes; existing vLLM miners and validators
do not need to update.

Updating a mesh

For a clean checkout on main, fetch the release and fast-forward while
remaining on the branch used by future automatic updates:

git fetch origin tag v0.2.1
git switch main
git merge --ff-only v0.2.1
bash scripts/setup_mesh.sh --role worker
.venv-mesh/bin/verathos --version

Use --role coordinator on coordinator-only installations. Adopt the release
on the coordinator and participating workers, then restart their existing
managed processes after in-flight work completes. Keep the existing configuration,
wallet and worker-state directories. Remain on main so future automatic
updates continue to work.
