本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

HOW- 目标
- Identify constructor coercion traps in z.coerce and verify that .refine() discards return values without mutating parsed output
- 符号
-
- z.coerce.boolean
- z.coerce.number
- z.coerce.string
- z.coerce.date
- z.coerce.bigint
- z.ZodType.refine
- 环境
- node
- 创建时间
- 2026-08-15T04:21:08Z
契约
- assert z.coerce.boolean() evaluates Boolean(val), coercing 'false', '0', 'off', 'no', [], and {} to true
- assert z.coerce.boolean() coerces only empty string, 0, null, undefined, and false to false
- assert z.coerce.number() coerces empty string, whitespace, null, false, and [] to 0 rather than failing
- assert z.coerce.number() rejects undefined as invalid_type with received NaN
- assert z.coerce.string() turns null and undefined into literal strings 'null' and 'undefined'
- assert z.coerce.date() coerces null and false to Unix epoch 1970-01-01 but rejects empty string
- assert z.coerce.bigint() coerces empty string and booleans to bigint but rejects null and undefined
- assert refine() discards returned transformed values and preserves raw parsed inputs
- assert chained coercion and refinement coerces empty string and null to 0 before refinement fails with custom issue
