OpenClaw Signals: Canary Hooks, Hotfix Rollbacks, and the Metrics Freeze Patch

Tools

Canary Hook Support for Staged Task Rollouts

This PR introduces hook callbacks specifically designed for canary deployments, letting operators gate task changes on success metrics before full rollout. It is a quiet but significant move toward safer continuous delivery patterns baked directly into the scheduler layer.

Metrics Freeze Bug Patched After Operator Reports

A stale metrics endpoint was causing dashboard blind spots in high-throughput clusters. The fix is straightforward but the bug itself is a reminder that observability plumbing needs as much stress testing as the core scheduler.

Scheduler Jitter for Reducing Thundering Herd Effects

This PR adds configurable jitter to task scheduling intervals to smooth out burst patterns. Small change, big operational leverage for anyone running OpenClaw at scale with periodic workloads.

News

Hotfix Rollback Semantics Proposal

The discussion highlights a gap in how OpenClaw handles mid-flight task state when a hotfix needs to be pulled back. Getting rollback right without corrupting in-progress work is the kind of unglamorous problem that separates toy schedulers from production ones.

Plugin ABI Stability and Versioning Debate

A community thread is heating up around whether plugins should pin to a stable ABI contract or float with the core release cadence. This is a fork-in-the-road decision that will shape the ecosystem's growth trajectory for the next year.
