# Audit s777d (cap 150-400k, arm A) - 29 Oct
Verdict: NOT VERIFIED, KILL-lean.
- Forward arm A n637: mean 0.99x, ex-top3 0.98x. Arm B n635: 0.71x. Below 1.0 at large n; kill rule (n>=20, upper bound <1.05) met.
- Same pattern as s777b/s777c (fwd ~1.0, ex3 <0.9). No edge after fees/slippage.
- Sellability / outside-seller / hand-rebuild not run: not worth it with mean <1.0.
Action: testmgr retire s777d, ledger killed.
