# Operation history and timeline

> Keep build and debug observations in chronological context.

Keep build and debug observations in chronological context.

## Before you start

Recorded operations or captured events.

## Workflow

Review recent operations in the project overview and use Timeline for available event data. Correlate errors with builds, configuration changes and captures. Attach the relevant evidence rather than an entire unrelated history.

## Interpret the result

History can contain records from an older configuration. Inspect timestamps and target/image identity before comparing events.

For an unexplained result, preserve the source/configuration and observation together. Use [Diagnose a failure](/workflows/diagnose) to turn it into a reproducible investigation. Check [support boundaries](/reference/limitations) before assuming a vendor-specific operation is implemented.
