There is no trusted configuration value, canonical allowed-root check, or validation that the resulting directory is the intended note vault. At the audited location: ```text /tmp/clawhub-codex-scan-v578qaprrnb6cdgd4hb7b7kgqs8eftnh-su1ZUq/artifact/scripts/capture_note.py ``` `parents[4]` resolves to the filesystem root, `/`. Consequently, the calculated destinations become `/Journal/...` and `/Inbox/...`, rather than directories inside the project or a clearly configured vault.
