- Add WELIST_PING_SIG_VERSION (1 legacy, 2 canonical JSON); default 1
- Sign WELIST-PING-V2\n + compact sorted JSON covering url, chain, height,
median_time, last_block_hash, info, base_fee, version and sig_version
- Fetch info/base_fee/version from the local /{chain}/info endpoint and sign them
- Fall back to null metadata on fetch failure; skip the fetch for onion URLs
- Normalize the advertised URL and bound metadata to match the WeTime service
- Activate v2 in bal-pusher.sh and document the TXT record setup
- Add unit tests for canonical payloads, URL normalization, metadata and onion detection
