Start with the evidence
Describe the task and the specific source location that is inaccessible. Use the approved access process rather than sending passwords or duplicating private files into a public location.
Work through the example
The reviewer can open the draft but not its supporting agreement. The access request should identify that agreement and the review purpose, not ask for unrestricted access to every customer folder.
Make the next step clear
Confirm that the intended source can be opened and that the link still points to the correct version. Keep the task moving without changing broader permissions on assumption.
Keep the source context
A handoff should state the task, evidence, current status and next owner. These are working practices rather than claims about specific permission, approval or collaboration features in Eftheia. Use the actual controls available in your workspace.
