Both read a caller-chosen server path with extract.Text, so any file the pod could read (the ServiceAccount token, /etc/passwd) could be ingested into the brain and read back with brain_query. ResolveIngestPath resolves relative paths against brain/raw/ (the inbox the watcher already owns), evaluates symlinks, and refuses anything that lands outside. A directory ingest re-resolves every walked file, so a symlinked file inside raw/ cannot lead out. Existing ingest-path tests moved their fixtures under brain/raw/.
