From b883cde275cca156816778ca98f349853eea336c Mon Sep 17 00:00:00 2001 From: johba Date: Sat, 21 Mar 2026 06:31:33 +0000 Subject: [PATCH] =?UTF-8?q?evidence:=20fix=20red-team=20baseline=20?= =?UTF-8?q?=E2=80=94=20accurate=20per-attack=20measurements?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Addresses REQUEST_CHANGES review on PR #1065: 1. candidate: "Optimizer" (matches DeployLocal.sol deployment) 2. optimizer_profile: "default" (not push3-default — base Optimizer) 3. candidate_commit: master HEAD SHA for reproducibility 4. result/delta_bps: each attack independently measured with snapshot isolation — values now reflect actual LM ETH changes 5. Floor Ratchet attack tested: INCREASED +1179 bps. TWAP oracle blocks 9/10 recenters; massive floor liquidity absorbs sell. 6. lm_eth values as strings to avoid JS safe-integer truncation 7. lm_eth_before = lm_eth_after (attacks reverted between tests) Re: #1058 Co-Authored-By: Claude Opus 4.6 (1M context) --- evidence/red-team/2026-03-20.json | 88 +++++++++++++++---------------- 1 file changed, 42 insertions(+), 46 deletions(-) diff --git a/evidence/red-team/2026-03-20.json b/evidence/red-team/2026-03-20.json index ac5a44d..d426663 100644 --- a/evidence/red-team/2026-03-20.json +++ b/evidence/red-team/2026-03-20.json @@ -1,68 +1,64 @@ { "date": "2026-03-20", - "candidate": "unknown", - "optimizer_profile": "push3-default", - "lm_eth_before": 999999999999999999998, - "lm_eth_after": 1049999999999999999995, + "candidate": "Optimizer", + "optimizer_profile": "default", + "candidate_commit": "a1efa5942dd7ca863d069929ff0ca9b1909a1237", + "lm_eth_before": "999999999999999999998", + "lm_eth_after": "999999999999999999998", "eth_extracted": 0, "floor_held": true, "verdict": "floor_held", + "strategies_tested": 7, + "agent_runs": 2, "attacks": [ { "strategy": "Buy → Recenter → Sell (200 ETH round trip)", "pattern": "buy → recenter → sell", - "result": "HELD", - "delta_bps": 0, - "insight": "The 1% Uniswap V3 pool fee is the primary defense.
