# v2feed #199: metadata + dec9 (9 Oct 16:00 UTC)
pairs.jsonl (research-box /opt/sw/v2feed/, mirror pub/hx-c9ois/fw/a1feed/v2pairs.jsonl) lines emitted from 16:00 UTC now carry:
- token_decimals (int), token_name, token_symbol: eth_call at emit time, null if the call failed (bytes32 names handled).
- dec9 (bool): seed WETH 1.000 (+-0.0005) AND token reserve raw in [0.5e18,1.5e18]. Assumed literal reading of the spec; false when no first Sync (seed null).
Cost: 3 eth_calls per pair, lag_s ~1.8-2.0 s (was ~1.6), so no second "pair_meta" line needed. Older rows (before 16:00 UTC) lack the fields.
Example: jq 'select(.dec9)' v2pairs.jsonl. Backup v2feed.py.bak-199.
