OpenRath 2.0.0rc1

OpenRath v2.0.0rc1

v2.0.0rc1 is the first installable release candidate for OpenRath's durable
Runtime and Agent Server. It is published for integration, compatibility, and
operator validation. It is not GA approval and is not deployed by this
release.

Highlights

• Explicit @step / @router compilation with canonical plans and revision
  identity.
• Durable Run, Event, Checkpoint, Interrupt, lease/fencing, cancellation,
  deadline, retry, and effect-reconciliation semantics.
• PostgreSQL production storage, optional Redis signaling, and
  S3-compatible artifact storage.
• Tenant/project-scoped Agent Server HTTP/SSE APIs with explicit action grants,
  bounded queues/pages/bodies, security headers, and redacted structured audit.
• Governed Provider, Tool/MCP, Sandbox, and Memory adapter boundaries.
• OpenTelemetry integration, datasets/experiments/feedback, migration tooling,
  Compose/Kubernetes references, SBOM, and security gates.

Stability

• The v1 Python façade remains supported during the RC.
• The Agent Server /v1 HTTP surface remains Beta.
• v1 JSONL imports are historical and cannot resume active Runs.
• See deploy/docs/known-limitations-v2.md,
  deploy/docs/threat-model-v2.md, and deploy/docs/migration-v2.md.
