Fix the monitor so it shows real data. Keep everything else unchanged.\n\n1. ADAPTIVE WINDOW:\n   - Default LOG_WINDOW_BLOCKS = 3000 (was 100)\n   - Add a UI input: \"Window (blocks)\" at the top, default 3000, min 50, max 50000\n   - User can change it live without restarting the monitor (next poll uses new value)\n   - Status bar shows current window value\n\n2. POLLING CHANGES:\n   - Replace eth_blockNumber with eth_getBlockByNumber(\"latest\", false) — gives both block number and timestamp in one call\n   - After the eth_getLogs call, for each pool that has at least one swap in the window, call eth_getBlockByNumber(swapBlockNumber, false) to get that block's timestamp (one call per active pool, usually 1-2)\n   - Total extra calls per poll: 1 (latest block) + N active pools. All via the public RPC.\n\n3. STALENESS:\n   - Add a \"Last Swap\" column to the pools table: elapsed time = latestBlock.timestamp - swapBlock.timestamp, formatted as \"Xm ago\" or \"Xh Ym ago\"\n   - Color coding: green < 30m, yellow 30m-2h, red > 2h\n   - Add a \"Max staleness\" input next to the threshold, default 7200 (seconds), user-settable\n   - If elapsed > max staleness, mark pool \"STALE\" in the table and EXCLUDE from spread table and auto-mode\n\n4. LIQUIDITY CHECK (empty pool detection):\n   - For each pool with at least one swap in the window, call PoolManager.getSlot0(poolId) via eth_call\n   - ABI: function getSlot0(bytes32 id) external view returns (int24 tick, uint160 sqrtPriceX96, uint24 protocolFee, uint24 lpFee)\n   - If sqrtPriceX96 == 0, mark pool \"EMPTY\" and EXCLUDE from spread table and auto-mode\n   - If the eth_call itself fails (RPC error, timeout), mark that pool \"UNKNOWN\" and exclude it from spreads. Do NOT fail the entire poll — other pools still display normally.\n   - Do NOT add a separate price column from slot0. Keep using 1.0001^tick for the displayed price.\n\n5. SPREAD TABLE:\n   - Only include pools that are: active (has swap in window) AND not stale AND not empty AND not unknown\n   - If fewer than 2 pools qualify, show \"No tradeable spreads\" in the spread section\n   - Everything else about the spread table (columns, top 5, GREEN/RED verdict) unchanged\n\n6. AUTO-MODE GUARD:\n   - Auto mode only fires when both pools in the spread are not stale, not empty, and not unknown\n   - Log the skip reason in the activity log: e.g. \"auto skipped: pool 3000/60 stale (3h 12m)\"\n\n7. KEEP UNCHANGED:\n   - 30s poll cadence, 60s RPC error retry\n   - Quote mechanism (router revert decode)\n   - Dry run → send flow, Permit2, button locking, 20-min deadline\n   - Wallet transfer section\n   - Balances display\n   - Activity log\n   - All existing error handling\n\nDELIVERABLE: Updated index.html + js/v4-arb-encoder.js.

I changed `getSlot0` to a working read. The empty-pool gap needs your decision.\n\n## Where the brief and the chain differ\nAll three were measured read-only on 2026-11-07.\n\n1. **`PoolManager.getSlot0` doesn't exist on the deployed contract.** The call reverts with empty data and the selector isn't in the bytecode. As written, every active pool would be UNKNOWN and there would never be a spread. I read the same data through `PoolManager.extsload(keccak256(abi.encode(poolId, 6)))`, which is how Uniswap's own `StateLibrary` does it. It costs the same one call per pool and returns the same fields.\n\n2. **`sqrtPriceX96 == 0` doesn't catch empty pools.** Zero only means the pool was never initialised, and such a pool can't have swaps, so EMPTY will rarely if ever appear. The 30000/600 pool has zero liquidity but a non-zero price (tick −887272). When its last swap is in the window, it shows as OK and tops the spread table as GREEN with a net of about 6e27%. No funds are at risk because the quote returns 0 and nothing sends, but **auto mode turns itself off on the first poll that picks it**.\n\n3. **Blocks are about 0.105 s apart, so windows are short in time.** A swap older than the window makes its pool inactive rather than stale.\n\n   | Window | Time covered | PONS/USDG result |\n   |---|---|---|\n   | 3000 (default) | about 5 min | 1 active pool, \"No tradeable spreads\" |\n   | 50000 (maximum) | about 88 min | 3 active pools |\n\n   The default 7200 s limit therefore can't trigger on this chain and the red colour can't appear. STALE only appears if you set Max staleness lower than the window's time span. I kept your defaults as written.\n\n## What was built\n- **Window:** there is a live \"Window (blocks)\" field, and the status bar shows its value.\n- **Polling:** each poll now makes 2 calls plus 2 per active pool, and `eth_blockNumber` is gone.\n- **Staleness:** there is a colour-coded Last Swap column and a Max staleness field next to the threshold.\n- **Pool marks:** STALE, EMPTY and UNKNOWN appear in the Active? column, and those pools are left out of spreads and auto mode.\n- **Spread table:** it shows \"No tradeable spreads\" when fewer than two pools qualify.\n- **Auto mode:** it logs skips such as `auto skipped: pool 3000/60 stale (3h 12m)`, and still trades the best clean spread if one exists.\n\n## Choices the brief left open\n- A failed read of the swap block's timestamp also marks that pool UNKNOWN, since its freshness can't be shown.\n- A typo in Window or Max staleness keeps the last valid value, so it can't loosen the guard.\n- Each skip reason is logged once per pool until its status changes, not on every poll.\n- A spread you already selected keeps its Dry run and Send buttons if a pool later gets marked. Your guard covers the table and auto mode, and each send is still simulated first.\n\n## Other changes\n- **Race fix:** a poll still running when the pair changes could overwrite the new pair's data, and the extra calls made that more likely. It's fixed and tested.\n- **Solidity and README:** I also updated `src/V4PoolMonitor.sol` with its tests and rewrote the affected parts of the README.\n\n## Testing\n- **`forge build`:** passes on the pinned compiler.\n- **`forge test`:** 68 of 68 pass with your fuzz seed.\n- **`forge fmt --check`:** clean.\n- **JavaScript tests:** 99 and 18 pass, covering success and failure paths. Seven deliberate code breaks were each caught.\n- **Live RPC:** the real monitor ran read-only at 3000 and 50000 blocks and sent nothing.\n- **Not run:** a real browser or wallet (the page tests use a mock DOM) and Slither. No independent security review has been done.\n\nThe changes are uncommitted in the working tree.\n\n## Decision for you\n- **Should a pool with zero liquidity also count as EMPTY?** The Swap log already includes `liquidity`, so this adds no RPC calls and would stop 30","treeHash":"7ad5a1d07ec5e33b804bf82cd49e15905ccddfb2","usage":{"cachedInputTokens":1259509,"cost":{"source":"runtime","usdMicros":2735110},"inputTokens":21,"model":"claude-opus-5-5","outputTokens":58449,"runtime":"claude","turns":22,"wallClockMs":618516}}],"verification":[{"checks":[{"durationMs":1560,"exitCode":0,"name":"build","output":"Compiling 25 files with Solc 0.8.26\nSolc 0.8.26 finished in 1.47s\nCompiler run successful!\n","passed":true},{"durationMs":224,"exitCode":0,"name":"test","output":"No files changed, compilation skipped\n\nRan 31 tests for test/V4PoolMonitor.t.sol:V4PoolMonitorTest\n[PASS] testFuzz_OnlyAFreshInitialisedPoolIsTradeable(uint160,uint256,uint256) (runs: 256, μ: 4031, ~: 4056)\n[PASS] testFuzz_PoolIdsOfOnePairDifferByTier(address,address,uint8,uint8) (runs: 256, μ: 21081, ~: 20921)\nLogs:\n  Bound result 6\n  Bound result 0\n\n[PASS] testFuzz_QuoteRoundTripsThroughTheRoutersPrice(uint128,uint256) (runs: 256, μ: 24753, ~: 24525)\nLogs:\n  Bound result 312097284804992635938837149806451896\n\n[PASS] testFuzz_SlippageNeverIncreasesTheAmount(uint128,uint256) (runs: 256, μ: 7561, ~: 7731)\nLogs:\n  Bound result 2179\n\n[PASS] testFuzz_Slot0RoundTrips(uint160,int24,uint24,uint24) (runs: 256, μ: 5189, ~: 5189)\n[PASS] testFuzz_SpreadIsSymmetricAndZeroOnlyForEqualPrices(uint128,uint128) (runs: 256, μ: 11797, ~: 11788)\nLogs:\n  Bound result 19973499180807\n  Bound result 320\n\n[PASS] testFuzz_WindowSpansExactlyTheRequestedBlocks(uint64,uint256) (runs: 256, μ: 8030, ~: 8218)\nLogs:\n  Bound result 1042\n\n[PASS] test_ApplySlippageMatchesTheJavaScriptBridgeAmount() (gas: 4984)\n[PASS] test_DecodeQuoteRevertReproducesTheLiveQuote() (gas: 37916)\n[PASS] test_DecodeSlot0OfAnUninitialisedPoolIsZero() (gas: 3805)\n[PASS] test_DecodeSlot0OfTheLiveWords() (gas: 5700)\n[PASS] test_DecodeSwapTickFromTheEventData() (gas: 4107)\n[PASS] test_PoolIdMatchesCastAndJavaScript() (gas: 4880)\n[PASS] test_PoolKeysCoverTheSevenTiersWithDistinctIds() (gas: 58310)\n[PASS] test_PoolStatusSuccessAndEachExclusion() (gas: 10100)\n[PASS] test_QuoteRevertSelectorIsTheRoutersError() (gas: 3199)\n[PASS] test_RevertWhen_PairIsIdenticalOrZero() (gas: 28319)\n[PASS] test_RevertWhen_PoolKeysPairIsUnsorted() (gas: 16746)\n[PASS] test_RevertWhen_PriceIsZero() (gas: 17832)\n[PASS] test_RevertWhen_QuoteDataIsNotThePriceCheck() (gas: 62468)\n[PASS] test_RevertWhen_SlippageAbove100Percent() (gas: 8607)\n[PASS] test_RevertWhen_SwapLogDataHasTheWrongLength() (gas: 18832)\n[PASS] test_RevertWhen_WindowIsOutOfRange() (gas: 17897)\n[PASS] test_Slot0SlotIsTheHashOfIdAndPoolsSlot() (gas: 3492)\n[PASS] test_SortPairPutsTheLowerAddressFirstEitherWay() (gas: 5206)\n[PASS] test_SpreadFeeAndNetForKnownPrices() (gas: 9495)\n[PASS] test_StalenessColourBoundaries() (gas: 5365)\n[PASS] test_SwapTopicIsTheEventSignature() (gas: 3171)\n[PASS] test_VerdictIsStrictlyAboveTheThreshold() (gas: 5189)\n[PASS] test_WindowDefaultsAndBoundsMatchTheBrief() (gas: 4514)\n[PASS] test_WindowStartIncludesTheLatestBlock() (gas: 4990)\nSuite result: ok. 31 passed;
