A regulator walks into your office and asks the question security teams rehearse for: "Show me every place customer data lives." Your data team produces the inventory. The primary database is on it. The analytics warehouse is on it. The object store, the queue, the search index, the backup destination — all on it, with classification labels, retention policies, encryption details, and named owners. Then someone in the room mentions the agent worker pool, and the inventory has nothing to say. The pool has been running for nine months. Each worker has a local disk. The agents on those workers have been parsing PDFs, transcribing audio, downloading email attachments, and caching intermediate JSON between tool calls the entire time. Nobody put any of that on the asset register.

This is the scratch directory problem. Every long-running agent worker accumulates an ephemeral filesystem that grows organically as new tools are added — extracted text from a PDF parser, transcribed audio from a Whisper step, downloaded attachments from a Gmail tool, screenshots from a browser-use step, vector-search snippets cached for the next turn, intermediate JSON the agent emitted between two tool calls so the second one wouldn't have to re-derive it. Unlike databases and queues and buckets, this surface has no retention policy, no encryption-at-rest standard, no DLP scanner pass, and no entry on the data-classification spreadsheet. The platform team thinks "agent state" means the inference-provider context window. The SRE team thinks "agent state" means the durable database. The worker's /tmp/agent-workspace-${session_id}/ directory is a third copy of customer data that nobody owns.
