• Add: submit JSON data with /storage/add
• Read: retrieve JSON data with /storage/read
• Telemetry & Configuration: see Verifiable Storage for IPFS setup and retry policies

• Pair service calls with ros2 topic echo /peaq/tx_status to monitor confirmation phases (PENDING, IN_BLOCK, FINALIZED).
• Use confirmation_mode: FINAL in production for stronger guarantees.
• For files, publish via the peaq/storage/ingest topic handled by the storage bridge.
