- The buy uses `BuyAmount::WithMaxInput`, which applies slippage to maximum quote cost and is appropriate when fill priority matters.
- Buy parameters use post-trade reserves and LP/protocol/creator fee bps from the event.
- The event's raw and virtual quote reserves come from the same transaction snapshot. The hot path does not fetch the Pool account, avoiding both added latency and mixed-slot quotes.
- The example records the pre-buy balance and sells only the confirmed balance increase. It refreshes pool state and blockhash before selling.
- The first matching event asynchronously records the pre-buy balance; the next fresh event performs the trade without a balance RPC in the submission hot path. It sells only the confirmed balance increase and refreshes pool state and blockhash before selling.
- Use `BuyAmount::ExactInput` when the quote spend must be exact. That mode protects minimum output and can fail more often in an active pool.
- If baseline warmup fails, the example waits for another event. Once transaction execution starts, an error keeps the one-shot guard locked because submission or position state may be uncertain; inspect the signatures and account state before retrying.
Production bots should also add durable signature deduplication, a position state machine, SWQoS configuration, and bounded requoting. Do not solve slippage errors by setting `min_out` to zero.

- 买入使用 `BuyAmount::WithMaxInput`，适合优先成交的跟单/狙击场景，滑点限制最大 quote 成本。
- 买入参数使用事件中的成交后储备和 LP/protocol/creator fee bps。
- 原始 quote 储备和虚拟 quote 储备均来自同一笔交易的事件快照；热路径不再查询 Pool 账户，避免额外延迟和跨 slot 混合报价。
- 示例记录买前余额，只卖出确认后的余额增量；卖出前重新获取池状态和 blockhash。
- 第一个匹配事件用于异步记录买前余额，下一条新鲜事件才会交易，因此提交热路径不再查询余额；示例只卖出确认后的余额增量，并在卖出前重新获取池状态和 blockhash。
- 若业务必须精确花费 quote，应改用 `BuyAmount::ExactInput`。这会启用最小输出保护，在活跃池中更容易因状态变化而失败。
- 基线预热失败时会等待后续事件；一旦进入交易阶段，错误会保持单次执行锁定，因为提交状态或持仓可能不确定，必须先核对签名和账户状态再重试。
生产机器人还应增加持久化签名去重、持仓状态机、SWQoS 配置和有限次数的重新报价。不要通过把 `min_out` 设为零来处理滑点错误。
