I pulled the E2E diagnostics from main run 32885558008. The concrete failure was the workspace wrapper running new from the wrong folder. The same shard passed in the next three main runs: 32898142217, 32909638198, and 32917733900. This has not repeated, so I am closing it. If the same assertion returns, we can reopen with the new diagnostics.

[automated] Automatic quarantine is blocked for the reported target(s).

The current quarantine path expects a .NET method identifier such as Namespace.Type.Method. These reported targets do not use that format:

VS Code extension E2E (Linux, workspace-target-proof)

This is a target-format limitation, not evidence that the tests do not exist. A framework-specific test identity and quarantine path are needed for targets that are not .NET methods.

No quarantine change was made by this recommendation.

This has not repeated since 8/26 which was almost a month ago, so I am closing it.
