executeBuy (race condition):
- Multiple WebSocket events for the same market can arrive concurrently.
All calls saw no existing position and all proceeded to buy → 3x fills.
- Added _buyQueue (Map<conditionId, Promise>) that chains each buy for
the same market after the previous one. Second call now sees the filled
position and respects maxPositionSize.
redeemer (gas estimation error):
- Gamma API can return resolved=true before payoutDenominator is written
on-chain. Calling redeemPositions when payoutDenominator==0 causes the
contract to revert → UNPREDICTABLE_GAS_LIMIT from ethers.js.
- Now always verify on-chain payout after the API check. If on-chain
payout not set yet, skip and retry next interval.

- src/bot.js: same logic as index.js but no blessed TUI; writes plain
text to stdout so pm2 logs works cleanly on VPS
- ecosystem.config.cjs: pm2 config with live/sim envs, log files at
logs/out.log + logs/error.log, auto-restart policy
- logs/.gitkeep: track the logs/ dir (*.log files are gitignored)
- package.json: added bot / bot-sim / bot-dev scripts
Usage on VPS:
pm2 start ecosystem.config.cjs # live
pm2 start ecosystem.config.cjs --env sim # simulation
pm2 logs polymarket-copy

The Gamma API returns camelCase field names but the code used snake_case,
causing all lookups to return undefined:
- end_date_iso → endDate (full ISO datetime, not date-only endDateIso)
- game_start_time → removed (field doesn't exist)
- minimum_tick_size → orderPriceMinTickSize
- neg_risk → negRisk
- condition_id → conditionId
- accepting_orders → acceptingOrders
Because endDate was always null, the MIN_MARKET_TIME_LEFT expiry guard
was silently skipped on every buy — allowing buys into expired markets.

The const client = getClient() was declared twice in the same function scope
(line 318 for cancel-orders block, line 371 for the sell loop), causing a
SyntaxError at startup. Removed the redundant second declaration.

Polymarket rejects market orders below $1 USDC. Added CLOB_MIN_ORDER_USDC=1
constant and applied Math.max(config.minTradeSize, CLOB_MIN_ORDER_USDC) at
both the loop entry check and post-fill remainder check so sub-$1 remainders
are silently skipped instead of causing API errors.

Root cause: auto-sell GTC orders lock all shares in the CLOB's internal
ledger. When executeSell runs, it tried to cancel only position.sellOrderId
but this can fail silently, leaving tokens locked. The CLOB then rejects
the new sell with "not enough balance or allowance" because the balance
is committed to the existing GTC order.
Fix:
- Fetch all open orders for the specific tokenId via client.getOpenOrders()
- Cancel all of them with Promise.allSettled (non-fatal per order)
- Wait 600ms after cancellation so the CLOB updates its locked-balance
ledger before we place the new sell
- Fallback: if getOpenOrders fails, still attempt to cancel by
position.sellOrderId (previous behaviour) then wait 600ms
- Use correct cancelOrder({ orderID }) object form throughout

redeemer.js was calling redeemPositions() directly from the EOA private
key wallet. This is wrong for two reasons:
1. Conditional tokens are held in config.proxyWallet (Gnosis Safe), not
in the EOA — so the EOA has nothing to redeem
2. No maxPriorityFeePerGas was set, causing Polygon's "gas tip below
minimum" error (1.5 Gwei sent, 25 Gwei required)
Fix: replace the direct contract call with execSafeCall() (exported from
ctf.js), which is identical to the MM bot's redemption pattern:
- encodes calldata and executes via Safe.execTransaction()
- signed by the EOA, but msg.sender on-chain = proxy wallet
- enforces 30 Gwei minimum priority fee for Polygon
- retries up to 3x on transient RPC errors
Also remove the now-unused NEG_RISK_CTF_ADDRESS local constant
(CTF_ADDRESS and USDC_ADDRESS imported from ctf.js).

Two root causes fixed:
1. Missing ERC-1155 setApprovalForAll for copy-trade flow
- executeBuy: call ensureExchangeApproval() after a successful fill so
the CTF Exchange is authorised to move tokens before the next sell
- executeSell: call ensureExchangeApproval() before every sell attempt;
the function is idempotent (checks isApprovedForAll first, only sends
a Safe tx if approval is actually missing)
2. Stored shares can exceed real on-chain balance (fee deductions, float
drift across partial FAK fills)
- executeSell: query ctf.balanceOf(proxyWallet, tokenId) before selling
- If on-chain balance is 0 → position is already gone, remove it and skip
- If on-chain balance < stored shares → adjust down and log the delta
- Round sell amount to 4 decimal places to avoid sub-unit precision errors
Also add getOnChainTokenBalance() helper using a minimal CTF ABI slice.
