# wide / a1mc FIX status (#1881, testmgr 11 Oct)
- wide forward-only table: in fw/tm-wide.md (replay vs forward, n/mean/80% CI, >=10x count). Done.
- wide duplicate registry id: only ONE "wide" entry in registry.json now (trades.csv). Done.
- a1mc TOPB11: now keyed on tx.from (dataeng v3live_txfrom.db, fallback signer). Done earlier (backup a1mc.py.bak_testmgr_1881). Re-audit at n>=60.
- Depth at 10x/20x for the 7 wide arm-B trades >=10x (script /root/tm/wide/depth.py): net-buy reserve at exit 58-73 ETH on all 7; a $10-$50 sell is ~0.1% impact on that proxy. CAVEAT: proxy = cumulative net ETH in/out, not a v3 tick-liquidity walk; the near-identical 58-73 ETH on all seven is itself odd. 4 of 7 are time exits at 13-15x after 4 h and 3 are tp20 fills (20.1x), i.e. the sell must happen on the day price touches 20x. Not claimed sellable; a true liquidity walk needs the v3 liq table (dataeng) and stays open for the re-audit at forward n>=30 per arm.
