bt view is an interactive terminal UI for browsing logs, traces, and spans. Use it to inspect individual requests, drill into LLM conversation threads, and navigate span hierarchies. 
bt view logs                                    # Browse project logs
bt view logs --window 30m                       # Last 30 minutes
bt view logs --list-mode spans                  # One row per span instead of per trace
bt view logs --search "error"                   # Full-text search
bt view logs --url <braintrust-url>             # Jump to a specific view
bt view trace --url <braintrust-url>            # Open a specific trace
bt view span --url <braintrust-url>             # Open a specific span
