In `@testnet_oro/proposals/proposal_25.json`:
- Line 15: The metadata field in proposal_25.json currently uses the placeholder
string "ipfs://CID"; replace that placeholder with the actual IPFS CID for the
proposal metadata (e.g., "ipfs://Qm..." or "ipfs://bafy...") so the metadata
points to the real document; update the "metadata" value in the JSON (the
"metadata" key in proposal_25.json) with the correct CID string, ensuring proper
JSON quoting and that the CID is a valid IPFS content identifier.
