Review a Mugi V1 cumulative buyback plan for chain 1, allocation-test consumer 0x161DB86AdFfb56Af0926fEee4C2d6AEb86b278a2, at absolute block 26228656, hash 0xdb7e68ce15c393e52f617ae14119b54050375c24ad946e2c6032bf7c4bbc3a07. Concatenate snapshot_NNN and plan_NNN definitions in numeric order to recover canonical JSON. Check snapshotHash=keccak256(UTF8(snapshot JSON)). Use only this pinned snapshot; do not substitute current prices or a rolling window. Match roundId(), aliveMask() and roundBudget(1) to the snapshot round, alive set and budget; check nonce greater than recorded nonce, deadline after snapshot time and no later than budget deadline, zero dead allocations, exact total conservation, 75–125% integer bounds and cumulative spent floors. This is an externally proposed allocation: assess its stated bounds; do not claim the local rule generated it. Verify expectedPlanHash=keccak256(abi.encode(uint256(chainId),address(hook),uint64(roundId),uint64(nonce),uint64(deadline),uint256[10](allocations))). Return bytes32 0x419c0c9fe715d87d664c3fd38a167f8aade237aa6effbac89c1132ccee140a0d only if every check passes; otherwise return bytes32 zero. This reviews data and arithmetic, not expected investment returns. The local snapshot must also be independently checked against the identified block when chain evidence is supported; do not imply such verification from panel arithmetic alone.
