spark_executor/core/job_writer.py provides write_job_file(code, jobs_dir=None) that resolves the output directory in this order: 1. explicit jobs_dir argument (for tests + programmatic override) 2. SPARK_EXECUTOR_JOBS_DIR environment variable (operator override) 3. DEFAULT_JOBS_DIR = './data/jobs' (gitignored, persists via volume mount) Filenames are job_<UTC-stamp>_<random-hex>.py — same-second writes still get distinct names via the random suffix, so concurrent agents won't clobber each other. 8 tests cover: arg>env>default precedence, dir auto-creation, env-var override, default fallback in a tmp cwd, and uniqueness under concurrent calls.
