What changed, and why it matters
This commit removes one DNS seed server (seed.testnet.bitcoin.sprovoost.nl) from the list used by Bitcoin Core's testnet3 network. DNS seeds help new nodes find peers when they first join the network. The change is a routine operational update by the seed operator and does not fix or introduce any security vulnerability.
No security action required. Treat as normal maintenance; verify the remaining seeds are operational if desired.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch deletes a single hardcoded testnet3 DNS seed from src/kernel/chainparams.cpp and updates the corresponding functional test fixture JSON. No code logic, validation rules, cryptography, or network protocol behavior is changed. The remaining four testnet3 seeds continue to provide peer discovery.
