v1.0.26

Highlights

• Added end-to-end OpenTelemetry observability for CLI commands and model, agent, dataset, training, image, video, and streaming workflows, with Volc telemetry enabled by default.
• Added a persistent observability.enabled setting and surfaced trace IDs in structured errors and terminal diagnostics to make support and incident correlation easier.
• Extended instrumentation across API calls, downloads, update checks, authentication, and long-running workflows while keeping telemetry fail-open and bounded.

Reliability and workflow

• Suppressed telemetry in CI and postinstall contexts, applied sampling and content-safety controls, and bounded concurrent flushing so observability cannot block normal CLI execution.
• Improved async workflow error classification, downloader and updater behavior, atomic configuration writes, and Windows file-handling and read-timeout paths.
• Expanded coverage for command lifecycle hooks, API errors, streaming and generated-content workflows, config persistence, downloads, and Windows-specific behavior.

Distribution

• Published @volcengine/ark-cli@1.0.26 with binaries for the six supported desktop and server targets.
• Revalidated the resolved Volc Skills tree and CN CDN manifest against the immutable v1.0.26 source before GitHub fallback publication.

Compatibility

• No breaking CLI flag, structured-output field, wire JSON schema, or public exported-symbol changes.
• Observability failures do not fail commands, and explicit configuration can disable collection.
• GitHub remains a fallback; the Volcengine CDN remains the primary binary and Skills source.
