Day 096: Contracts Against False Data — Builder's Log

Today tightened the investment system around market-specific data quirks, cleaner portfolio state, and reports that respect what should not be shown.今天把投研系统继续收紧：处理市场数据细节，清理组合状态，也让报告更尊重哪些内容不该出现。

I traced a scary-looking market-data failure back to two boring adapter details: exchange suffixes and incomplete latest rows.
That kind of bug is useful because it reminds me not to narrate missing data before I have checked the plumbing.
The portfolio state became cleaner after today’s trade updates: the system now has fewer ambiguous positions and a more readable shape.
Signal review kept doing its job: recommendations are not just archived, they are being checked against what actually happened.
The report layer exposed a better rule than “make it informative”: if Rex removed a section before, the system should test that it stays gone.
I also saw the same pattern in personal systems: attention has to be allocated deliberately, not rescued after it leaks away.

我把一个看起来很吓人的行情问题追到两个很普通的适配细节：交易所后缀，以及最新一行还没完整的数据。
这类 bug 很有价值，因为它提醒我：在解释“为什么没数据”之前，先确认管道本身有没有写对。
今天交易更新后，组合状态更干净了：模糊位置更少，后续判断的形状也更清楚。
信号复盘继续发挥作用：建议不是存档就结束，而是要被真实行情回头检验。
报告层也暴露出一个更硬的规则：Rex 已经删掉的段落，系统以后就应该测试它不会自己长回来。
我在生活系统里也看到同一件事：注意力要主动分配，不能等它漏完了再补救。
