`bsc_pool_scan`The full honeypot / rug-pull / liquidity read behind bsc_token_preflight, every figure and its source. Use it when the preflight’s short answer is not enough (an audit, a dashboard, a second look at one figure); for the go/no-go before a trade call bsc_token_preflight, and for the route alone pancakeswap_best_route. Measure what a trade on BNB Smart Chain would actually cost, for ANY token or pool — before placing it. Reads the pool live from the chain and returns: real cost per trade size (price impact + swap fee + transfer tax together, not the headline slippage a router shows), the USD size that moves the price 1% in each direction, the transfer tax measured from executed trades (simulated on chain at that block when the pool has not traded in the last hour, and flagged measured:false) rather than taken from a label, how much of the token's liquidity the readable pool actually holds, and whether the LP is burned or still withdrawable — plus our own sell simulation on the router from a fresh address (sellability). A token still raising on four.meme with no pool yet is measured from four.meme's own contract instead (curve: raise progress, price, buy/sell cost per size, fee). Works on PancakeSwap V2, V3 and Infinity CL (an Infinity pool is found from its key on chain and priced by PancakeSwap's own Infinity quoter, its hook included), Uniswap V2 and V3, and Biswap; a token still on four.meme's or flap.sh's launch curve is read from that curve. Read tax.measured and tax.source before using the cost columns: a tax that could not be measured comes back null with a warning, never as 0%; quotable: false with a reason is an answer, not an error. Also returned: deeperPoolElsewhere (a bigger pool for the same token than the one read), tax.simulated (an independent cross-check next to the measured tax), lp.custody (who holds the LP of a V2 pair, wallet by wallet, the deployer flagged; complete from the pair's own logs when it is under an hour old; V3 positions not read), hol	The full honeypot / rug-pull / liquidity read behind bsc_token_preflight, every figure and its source.

`bsc_token_preflight`START HERE for any BSC token. Honeypot and rug-pull pre-trade check, measured not labelled: For an agent about to trade ANY token on BNB Smart Chain: the check to run before every trade, in one call and at YOUR size. Answers the two questions that matter before signing - can I get in, and can I get out again - and what the trip costs. Returns stop[] (facts that end an automated trade: the sell does not go through from a fresh address, nothing quotes, half the money is gone on an immediate round trip) and caution[] (facts to weigh, each with its figure and the line it was measured against: a transfer tax that is high, unknown or changeable by the owner; a size that moves the price more than 1%; a deeper pool elsewhere; LP that can still be withdrawn, and by whom - the deployer holding the LP is named - or that was already withdrawn; holders unknown or concentrated; the deployer or a wallet it funded selling into the pool (net of liquidity it added back), a top holder selling over a quarter of its balance, launch buyers holding over 10%; contract flags), then the figures: the token’s spot price in dollars from the pool read (token.price_usd), the best PancakeSwap route at this size, what you pay and receive, the slippage in bps this size really needs, per side, from the measured tax (a fee-on-transfer token reverts below its tax), the round trip with the transfer tax applied (measured from executed trades, or, when the pool has not traded in the window, simulated on chain at that block — the answer says which), the 1% depth in both directions, LP burned and who holds the rest, pool and token age, the swaps of the last hour and who sold in it (flow). A short answer, built from bsc_pool_scan and pancakeswap_best_route, which stay available under details for every figure behind it.
