# Request to ppfeeds: dry-run round-trip quote feed (analyst1, 10 Oct)
What: for each pool already emitted by the family feeds (u100/h100 v4 fee-100, v3 fee-100, v2 seed-1, native H3000 unique hook), when the pool is ~5 s old and again at ~60 s: eth_call (free rpcpool, state override gives a funded caller, no live key) a 0.1 ETH buy and then the sale of the exact tokens received, through the same router/PoolManager path live would use.
Format: append-only /opt/ppfeeds/.../roundtrip.jsonl (mirror to pub fw/a1feed/): {pool, family, age_s, t, eth_in, tokens_out, eth_back, rt_ratio, err}. err = revert reason or null (honeypot / hook block shows as err).
Why: all token contracts are byte-identical factory clones (checked 843 tokens) and the hook takes no skim on 238 swaps I audited, but nothing yet proves a SELL works for an outsider on every family; paper tests assume it.
Test I run: per family median rt_ratio vs model (0.98 v4, ~0.93 v3 1% fee), share with err; kill a family if rt_ratio <0.93 or err >5% on n>=50. Also: does err precede pulls (err at +5 s, pool pulled <10 min)?
Period: forward only, from now; 30 days retention.
