3-reviewer simplify pass (reuse/quality/efficiency) findings:
- cron/scheduler.py _run_job_script: the ORIGINAL that
lifecycle_guard._resolve_script_path documents mirroring had the exact
same unguarded expanduser() — a NUL-bearing script value survives
creation (the guard treats it as nothing-to-scan) and crashed the
scheduler at fire time with ValueError instead of a clean job failure.
Same ingestion contract applied; regression test added.
- lifecycle_guard._resolve_script_path: get_hermes_home() -> Path.home()
raises RuntimeError when neither HERMES_HOME nor HOME resolves
(arbitrary-UID containers); the cron entry point called it bare.
Caught -> None; totality test added.
- terminal_tool: stale 'cat ...' docstring updated to the bounded
head -c form.
- lifecycle_guard: dead 'script_text and' condition dropped (guarded by
'if not script_text: continue' directly above).
Efficiency reviewer: no material findings (measured — encode/expand
costs negligible vs walk I/O, no timing regression vs base).
