Human job

  • Start from Home, Proxy, PCAP, a TraceGrid CSV, or the bundled demo.
  • Reopen, reorder, configure, and delete saved Scenarios.
  • Use compact persisted source facts to understand what was captured; use Run Trace for the current session's execution evidence.

Automation handoff

  • Replay-specific MCP and CLI creation/execution are not shipped.
  • Scenario creation and execution remain Workbench workflows.

Boundary

Free keeps up to three ordinary Scenario tabs. The fixed bundled demo is the only creation exception. RunSession feedback and Run Trace are not persisted as Workbench report history.
