PR #41d2c758c ("Fix unsafe gateway media path delivery") tightened
`validate_media_delivery_path` so that artifacts emitted by the agent
must live inside `MEDIA_DELIVERY_SAFE_ROOTS` (Hermes-managed cache
dirs) or an operator-allowlisted root via `HERMES_MEDIA_ALLOW_DIRS`.
Two kanban-notifier tests put their PDFs and PNGs under pytest's
`tmp_path`, which is correctly rejected by the new validator. They
started failing on main as soon as that PR landed:
FAILED tests/hermes_cli/test_kanban_notify.py::test_notifier_uploads_artifacts_on_completion
FAILED tests/hermes_cli/test_kanban_notify.py::test_notifier_artifact_delivery_skips_missing_files
Symptom in logs: "Skipping unsafe local file path outside allowed
roots". The validator is doing exactly what it should — the tests were
relying on the looser pre-fix behaviour.
Fix: add `HERMES_MEDIA_ALLOW_DIRS=tmp_path` to the `kanban_home`
fixture so artifacts under `tmp_path` are recognised as safe. This is
the same allowlist mechanism the operator-facing env var documents.
