Archived builder failure

Used Rust1.89 configuration, jobs2, GCC, Nushell0.112.2, fresh candidate path; 20GiB guest disk was free. The actual archived scripts/build-candidate.nu failed at line24 with nu::shell::column_not_found: LAST_EXIT_CODE is absent following let prefix = (^mktemp ... | str trim). No Cargo build began. The staging directory creation lies before the script's try/catch and leaves an empty staging directory on this path. Log /tmp/cyber-final2-linux-build.log, exit1.

Required correction: capture mktemp with complete, validate its explicit exit_code, and derive the staging path from stdout. The source owner was notified; the frozen FINAL2 source was not edited. A corrected archive requires a new identity and a fresh native build, full installed smoke, packaging and node gate. Existing rehearsal artifacts remain preserved and do not certify FINAL2.
