v0.31.1

Runtime line

Holon v0.31.1 is part of the Rust runtime line. The Rust runtime is now the main holon binary.

This patch release hardens scheduler activation settlement and recovery: reducer-consumed duplicate TaskResult messages now terminalize with explicit reducer-only Turn evidence, unsettled scheduler claims are reconciled through bounded one-shot recovery that quarantines poison claims while releasing execution lanes, and claims whose task waits were revoked fail closed through the same interrupt-and-quarantine path.

Supported binary assets for this release are Linux amd64, macOS amd64, and macOS arm64.

Changes

• Terminalize reducer-consumed duplicate/suppressed TaskResult messages with explicit reducer-only terminal Turns instead of fabricated provider or assistant evidence, and settle replayed task-restart messages idempotently (#2601).
• Reconcile unsettled scheduler claims through a shared pure planner across bootstrap, online settlement failure, and scheduler-recovery debug: replay is bounded to one fenced recovery generation, repeated or ambiguous poison claims are interrupted and quarantined with durable audit evidence while execution lanes are released, and unsettled/quarantined claim counts surface through agent status and metrics (#2602).
• Quarantine claims with revoked task waits: a cancelled exact task wait is treated as negative continuation authority and converged through the canonical interrupt-and-quarantine planner, with exact --message-id scheduler-recovery targeting plus claim age, lane-blocking, and health diagnostics (#2603).
