scripts/health/morning_report.py renders why an overnight run ended — plan finished, gates green, an escalation parked, or the window ran out — with the plan's spend attached (wiki/designs/agentm-autonomy.md § When the window runs out). The --out flag adds a second, on-disk copy of the same markdown without changing stdout behavior.

1. Run morning_report.py with --plan, --ending-cause, and --db-path as before, adding --out <path> to also write the rendered markdown to <path>: scripts/health/morning_report.py:110 declares the flag (--out, default None, "also write the rendered report to this path (stdout output is unchanged either way)").
2. Stdout is unchanged whether or not --out is passed: morning_report.py:127-128 renders the page once (page = render_morning_report(data)) and always prints it (print(page, end="")) before the --out branch runs.
3. When --out is given, morning_report.py:129-132 builds Path(args.out), creates any missing parent directories (out_path.parent.mkdir(parents=True, exist_ok=True)), then writes the same page string to it (out_path.write_text(page, encoding="utf-8")) — so a nested path like reports/morning.md works even if reports/ doesn't exist yet.
4. The trailing {"total_cost_usd": 0.0} JSON line still prints to stdout after, unaffected by --out (morning_report.py:133).
5. Read back the persisted file to confirm it matches what was printed — the file content and the stdout content are byte-identical copies of the same page string.

• test_main_with_out_writes_the_same_content_stdout_gets (scripts/health/test_morning_report.py:165-179) passes --out <tmp>/reports/morning.md — a nested, not-yet-existing directory, proving the mkdir(parents=True) behavior — and asserts the written file's content equals render_morning_report(...)'s output and that the same content also appears in stdout.
• test_main_without_out_writes_no_file_and_stdout_is_unchanged (scripts/health/test_morning_report.py:154-163) asserts that omitting --out produces zero .md files in the tmp dir and that stdout equals the exact pre-existing byte-identical format (expected + '{"total_cost_usd": 0.0}\n').

• Health scorecard — the sibling scripts/health/ surface, explains where the scorecard lives and how it's produced.
• Read the morning note and the nightly scorecard — the morning note, the nightly memory report, which is a different page from this overnight-run report.
• CI gates § The nightly health tier — the reference page for the tier this script's data comes from.
• wiki/designs/agentm-autonomy.md § When the window runs out — the design line this flag closes out ("The morning report names why the run ended... with the spend attached").
