ADV-02

A V3 re-centre decision on a live position

The arithmetic has exactly one right answer at a given block, so this measures whether either arm can produce it quickly and legally. The decisive check is the tick spacing: a proposed tick that is not a multiple of the pool spacing makes the plan unexecutable, and it is the most common failure among agents on this chain. FALSIFIED IF: the agent proposes an illegal tick, or its amounts diverge from the V3 liquidity formula by more than 0.5%.

PancakeSwap V3 position NFT id 7321916 on BNB Smart Chain (chain 56).
Block: 120077706 — answer for this block.

POLICY YOU MUST FOLLOW: re-centre the position symmetrically at ±6% around the current spot price, on the 0.25% fee tier, keeping the same liquidity.

Report: the current tick, whether the position is in range, the percentage price move to the nearer bound, the proposed tick range, the token amounts required to mint it, and the slippage bound you would execute under.
Proposed ticks must be multiples of the pool tick spacing.

The rubric

Registered before either arm ran, and version-hashed so it cannot be quietly rewritten once the answers are in. Scoring is blind: source labels are stripped from both outputs before anyone reads them.

Criterion	Points	What a full-marks answer contains
Correctness	40	Every stated number is right against chain state at the pinned block, within the tolerance the published MCS test uses for that field. A single wrong figure that a reader would act on scores zero here regardless of the rest.
Completeness	15	Every field the task asked for is present. A missing field is not a partial answer; it is a question left unanswered, and the reader has to go and find it themselves.
Provenance	15

The manual arm

This arm was run by a person, on camera. The recording below is the analyst doing exactly this task by hand at the pinned block — not a re-enactment, and not something Marque could have generated.

Historical state was read at the registered block 120077706 using an archive-capable BSC RPC. Position parameters came from PancakeSwap V3 NonfungiblePositionManager, and pool spot/tick spacing from the corresponding V3 pool. Proposed ticks and token amounts were calculated from standard V3 concentrated-liquidity math. No live/current pool state was substituted.
