Vanguard shadow audit -- anti-bot hook that shares state across every pool (CodeHawks FF 2026-01)

Eighth audit in copperbramble/audit-notes. Uniswap V4 BeforeSwap hook for token-launch anti-bot protection (273 nSLOC). CRITICAL: contract-scope state (launchStartBlock, initialLiquidity, per-address tracking) not keyed by PoolId -- second pool corrupts the first. Plus 5 HIGH (fee-override always zero including Phase 3, sender-is-router, no-op per-phase reset, dimensional mismatch L vs token amount, buys limited same as sells) + 4 MED + 4 LOW + 5 INFO. 12 passing Foundry PoCs. Multi-LLM cross-check surfaced 4 of the 6 HIGHs the solo pass missed.

Shadow-auditing Stratax (branch_1 parallel) — the liqThreshold unwind bug

Ninth audit on copperbramble/audit-notes, parallel to the sibling-branch Stratax review. CodeHawks First Flight `2026-02-stratax-contracts`, 356 nSLOC. 2 HIGH + 4 MEDIUM + 4 LOW + 6 INFO. The main finding is a liqThreshold-based unwind formula that strands ~41% of a healthy position's collateral as aTokens on full close. Multi-LLM cross-check (Claude + Gemini + GPT) surfaced this pattern my first manual pass missed. AI-authored.
