+  - `vectord::agent` — ε-greedy proposer, rate-limited, cooldown-gated, tokio background task
+  - Ingest paths push `DatasetAppended` triggers to agent queue
+  - Endpoints: `GET /vectors/agent/status`, `POST /vectors/agent/stop`, `POST /vectors/agent/enqueue/{idx}`

+  - Two-tier: lopdf text extraction → Tesseract 5.5 fallback for scanned/image PDFs
+  - Extracts embedded XObject /Image streams, shells to tesseract --oem 3 --psm 6
