Recovering an agent task after OpenShell containment
OpenShell can stop an agent after Kubernetes has accepted its scaling request. Recovery then depends on the Deployment state, available replicas and customer-facing result.

Why a Prometheus error-rate query can return no data
Zero errors, no traffic and absent series produce different PromQL results. Synthetic tests show how ratios, fallback zeros and absence checks behave for a checkout service.
How Kubernetes Memory QoS affects inference under pressure
Host-memory throttling can keep an inference process alive while its requests slow down. Effective kubelet settings and request deadlines explain the tradeoff.

OpenTelemetry’s Kubernetes attributes processor reaches v1
Kubernetes attributes connect agent calls to pods, workloads and paging routes. A processor migration can break those connections while telemetry still flows.

Why a 5 Whys investigation can branch
Evidence can split a 5 Whys investigation into several contributing causes. A concurrency example shows how to turn those explanations into useful tests.

Comparing incident sources with NotebookLM
Conflicting restart instructions show where a source-backed notebook helps: finding the relevant passages, dates and exceptions for the runbook owner.
