this compression is associated with a decrease in self-verification and uncertainty management behaviors, such as double-checking.
推理链缩短不是随机裁剪，而是专门切掉了「自我验证」和「不确定性管理」这两类高价值行为。这说明模型在感知到上下文压力时，优先砍掉的恰恰是最关键的质量保障机制——就像一个疲惫的审计师在工作量激增时，第一个省掉的是「复核步骤」。这对 AI Agent 的可靠性设计是一个严峻警告：上下文越长越复杂，模型越容易跳过自检。
Once zeitwerk mode is enabled and the configuration of eager load paths double-checked, please run: bin/rails zeitwerk:check
This is helpful because it allows you to detect/find eager load issues in dev before/without deploying.
I ran into an eager load error after deploying to staging...
Final Form makes the assumption that your validation functions are "pure" or "idempotent", i.e. will always return the same result when given the same values. This is why it doesn't run the synchronous validation again (just to double check) before allowing the submission: because it's already stored the results of the last time it ran it.
