A grep fed by a pipe filters that command's output, not the code, so its
pattern is not a graph lookup the agent skipped.

"""Rigorous edge-case coverage for the `graphify hook-guard` subcommand (#522).
|
|
|
|
Covers the shell-agnostic PreToolUse/BeforeTool guard that replaced the inline
|
|
bash hooks: the search/read detection matrix, the gemini BeforeTool contract,
|
|
fail-open behavior, output-dir overrides, subcommand dispatch, exit codes, and
|
|
UTF-8 (em dash) byte fidelity. Detection is exercised by calling _run_hook_guard
|
|
directly (hermetic, fast); dispatch/exit/encoding go through a real subprocess.
