 ## Current receipts
 
+- `fable-agentic-system-layer-checklist-20260702.json` — maps arXiv 2606.24937 agentic-system layers to local receipts and marks missing proof explicitly.
+- `agentic-ai-hitchhiker-research-map-20260702.json` — treats the arXiv 2606.24937 paper as advisory input only.
 - `stale-memory-quarantine-20260702.json` — quarantines stale `8098`/memory-only deploy claims.
 - `claude-public-artifact-advisory-map-20260702.json` — treats public artifact/system-prompt-like text as advisory only.
 - `adaptive-tap-pair-research-map-20260702.json` — bounds external red-team claims; requires denominators and confirmed/attempted rates.
