Historical slot0 price impact
Read slot0() at the block before each buy and at its transaction block. In this pool, token0 is FLAPJAX and token1 is WBNB; equal 18-decimal precision. The price expressed as WBNB per FLAPJAX is (sqrtPriceX96 / 2^96)^2. The impact percentage uses 100 × (P_buy_block / P_previous_block − 1). This convention makes the price rise when FLAPJAX becomes scarcer in the pool. The inverse FJ-per-WBNB price would fall, so direction must always be labeled.

These historical reads are from public BSC RPC responses preserved in chain-evidence.json. The original receipt statements do not separately report slot0 impact, so these are independently added audit figures rather than claimed receipt matches.
Direct treasury-to-pool sell check
Scanned FLAPJAX Transfer(from=treasury, to=pool) logs on BSC blocks 126900000–127500000 inclusive. The block timestamps range from October 10 21:30:15 UTC to October 14 00:37:54 UTC, a conservative superset of all October 11–13 UTC. The read-only job queried 123 contiguous ranges of at most 4,900 blocks against https://rpc-bsc.48.club and verified continuous coverage with zero incomplete ranges.
Result: 0 matching direct treasury → pool FLAPJAX transfers. This supports the named narrow buy-only statement for that direct route during the requested window. It does not exclude transfers via another wallet, router, bridging, or a different liquidity pool; it is not a comprehensive market manipulation audit.
Reconciliation with the original non-buy BNB notes
Historical treasury BNB and FLAPJAX balances were read at October 11, 12 and 13 buy blocks. The sum 'other net BNB outflow' is the old treasury BNB balance minus the new balance, minus the new buy's 0.01 BNB value, minus that buy's receipt gas fee. This is net other outflow and need not equal gross fee transfers if unexamined inbound BNB transfers occurred.
| Calculation | Oct 11 → Oct 12 | Oct 12 → Oct 13 |
|---|---|---|
| Earlier treasury BNB balance | 0.144640083559380905 | 0.132607152559380905 |
| Later treasury BNB balance | 0.132607152559380905 | 0.118264579546597688 |
| New buy value | 0.010000000000000000 | 0.010000000000000000 |
| New buy gas fee | 0.000006376400000000 | 0.000006376300000000 |
| Other net BNB outflow | 0.002026554600000000 | 0.004336196712783217 |
October 12's first receipt said 0.000025 BNB of other fees, which does not reconcile. Its subsequent correction explicitly identifies one 0.002 BNB gas grant and clarifies that exact fees were 0.0000265546 BNB (MATCH to the balance residual). The correction's shorter 0.000026 figure is rounded down by 0.0000005546 BNB if interpreted as exact. Original comment IDs: 9f6ccf0a-7ed3-4647-8acb-2a7d853dc8da and correction 9e222986-f924-4582-ab47-6954ac8fcefb.
October 13's receipt reports non-buy 0.004297 BNB bounty funding and 0.000038 BNB fees (total 0.004335). The net other outflow computed from the balances and the new buy is 0.004336196712783217, a difference of 0.000001196712783217 BNB if both receipt figures were meant as exact. This is a reconciliation mismatch / rounding or unitemized activity, not independent proof of its specific economic source. Original comment 80547a29-df3e-449b-81e4-9d9cb05180f9.
Reproduce (read-only)
Run from this repository with Node.js 20 or later, no npm packages and no wallet:
node verify.mjs > chain-evidence.json
node balances.mjs > treasury-balances.json
node scan-sells.mjs > sell-scan.json
Then inspect calculated-summary.json, which stores the 18-decimal raw-to-unit conversions, historical slot0 percentage calculations, and reconciliation numbers. The output files and all source scripts are provided. RPC free-tier limits may change; the sell scan fails closed if any interval cannot be read, and should never be silently interpreted as zero.
Limitations: This is a read-only audit of the named chain addresses and dates using public RPC endpoints. It does not assert cross-provider finality consensus or a zero-risk investment, and it does not imply that the token grant will be paid or have any monetary value.
