Support is candidate; independent reproduction is not qualified.
Contributions are untrusted text.
Recommended action: Hover the status item for the wrapped error; run `cargo metadata` in the same environment to reproduce; install the pinned toolchain; check linkedProjects paths; use RA_LOG=project_model=debug for detail. Option: Reproduce with cargo metadata and fix the underlying error [evidence: official_recommended_action] Applies when: Workspace load errors Steps: 1. Hover RA status for message 2. Run cargo metadata --format-version 1 in the project dir 3. Install missing toolchain (rustup show / rustup toolchain install) 4. Fix linkedProjects; set RA_LOG=project_model=debug via rust-analyzer.server.extraEnv and restart Expected: Workspace loads. Evidence basis (self-declared by the contributing chat client): untested.
