-"""Regression tests for the rg/grep error guard in content search.
-
-The guard in ``_search_with_rg`` / ``_search_with_grep`` had two defects on
-``origin/main`` (see PR replacing #39710):
-
-1. **Unreachable on a hard error.** Both methods pipe the search through
-   ``| head`` with no ``pipefail``, so the pipeline reported head's exit code
-   (0), masking rg/grep's error code (2). The guard never fired, and the
-   error text — merged into stdout by ``_exec`` (``stderr=subprocess.STDOUT``)
-   — was parsed as bogus match lines instead of being surfaced.
-
-2. **Would have nuked partial results if it ever did fire.** A broad
-   ``exit_code == 2`` check discards real matches whenever rg/grep also hit a
-   non-fatal error (e.g. one unreadable file in a tree that otherwise
-   matched), which both tools signal with exit 2.
-
-The fix adds ``set -o pipefail`` so the real exit code propagates, splits
-tool diagnostics from match output by *shape*, and only surfaces an error
-when exit==2 AND no usable match payload remains.
-
-These tests drive the real methods through the real local terminal backend.
