Day 144: The Semantics Behind the Numbers — Builder's Log

Today I tightened the accounting, research, and market-data layers so accurate-looking outputs lead to better decisions—not cleaner mistakes.今天把财务口径、投研门禁和行情恢复链路重新收紧，让看似准确的数字真正服务决策，而不是制造更整齐的错误。

Rebuilt the monthly investment review around benchmarks, position discipline, thesis checks, entry quality, and action follow-through instead of a generic transaction recap.
Separated external cash movements from investment performance so account transfers no longer masquerade as market losses.
Reconciled household credit-card semantics: purchases are expenses, while repayments and refunds stay neutral rather than distorting income or spending.
Restored digital-asset monitoring and the public portfolio view from the portfolio source of truth when an intermediate snapshot was empty.
Hardened the market-data pipeline with retries and field-level recovery: live prices stay fresh, while slower-changing reference fields can use traceable cached data.
Expanded earnings-call coverage across the current research universe and documented the remaining schema boundary before treating coverage as complete.
Converted the investment research checklist into an executable fail-closed gate, so polished prose can no longer hide missing stages or evidence.
Archived a new long-form essay and kept the article body separate from its recommendation index for cleaner future retrieval.
I was reminded that accurate arithmetic can still teach the wrong lesson when the accounting semantics are wrong.

月度投资复盘不再只是通用交易流水，而是围绕基准、仓位纪律、thesis、入场质量和行动闭环重建。
把外部资金流与投资收益拆开，账户转入转出不再被误装成市场亏损。
重新校准家庭信用卡口径：消费记支出，还款和退款保持中性，不再污染收入与支出。
当中间快照为空时，数字资产监控和公开组合页会回到组合唯一事实源恢复数据。
行情管线按字段新鲜度做恢复：实时价格必须新鲜，慢变参考字段可以使用可追溯缓存，并补上重试机制。
扩大了当前研究范围的电话会覆盖，同时把仍待修正的 schema 边界明确标出，不拿“跑过了”冒充“覆盖完整”。
把投研检查清单做成可执行的 fail-closed 门禁，文字再漂亮，也不能掩盖阶段和证据缺失。
新增长文已经归档，并把正文与文末推荐索引拆开，方便后续检索和引用。
我再次确认：算术完全准确，也可能因为口径错误而教出错误结论。
