fallback_agent_home_cwd

Error message

Issue ${issue.identifier ?? issue.id} expected a project workspace, but ${input.adapterType} would launch from agent fallback cwd "${effectiveCwd}".

What it means

The issue's execution policy expects a project workspace, but the resolved effective cwd is the agent's default fallback directory, meaning no project workspace was attached or restorable for this adapter launch. The guard catches this before the agent starts in the wrong location.

Solutions

1. Configure the project workspace so the adapter launches from it instead of the agent fallback cwd.
