## 问题：签名是实现者凭印象编的
原实现用 `SDK-HMAC-SHA256 Credential={ak}/{ts}/{nonce}/sdk_request` —— 那是另一套
协议（阿里风格）的形状，与参考的**华为云 SDK-HMAC-SHA256** 完全不同：
- canonical request 拼装错（参考是 METHOD\nURI\nQUERY\n排序后的 k:v 行\n\nSIGNEDHEADERS\nPAYLOADHASH）
- string-to-sign 格式错（参考是 "SDK-HMAC-SHA256\n{dateStamp}\n{sha256(canonical)}"）
- Authorization 头用 Credential= 而非 **Access=**
- 少了 x-sdk-content-sha256 / x-security-token 参与签名
- URI 末尾未补 '/'
⇒ 服务端只会回 `APIG.0301 ... verify ak sk signature fail`，看起来像"账号/权限问题"，
这个平台注定领不到额度。
## 修
逐行对齐参考 `sign.ts:signRequestHuawei` + `codearts-credits.ts`：
1. canonical request / string-to-sign / signature 全部照参考
2. 参与签名的头：host / x-sdk-date / x-sdk-content-sha256 / x-security-token
（非 GET 再加 content-type），按字典序拼 SignedHeaders
3. Authorization = `SDK-HMAC-SHA256 Access={ak},SignedHeaders=…,Signature=…`
4. Agent-Type / X-Language 是**签名后**追加的，绝不进 canonical（否则验签失败）
5. URI 末尾补 '/'
6. 完整领取 4 步（参考的 6 步判定顺序）：账户类型 → 活动列表 → claim →（benefit.id
非空时）confirm；用 done 哨兵回给 claim_daily（它自己发多个请求，契约只发一个）
- 非积分账户 → inactive（Token 账户不该被报成"领取失败"）
- activity.claimable=false 且状态属已领取态 → already-claimed（**唯一的幂等保护**，
本协议没有幂等键）
- confirm 失败不算整体失败（积分已在待确认态），只是降级提示
## 判据（差分，与参考逐字节一致）
`TestCodeArtsSignatureMatchesReference` + `tools/codearts_sig_expected.mjs`
（照抄参考函数生成期望值）。覆盖 canonical / string_to_sign / signature /
SignedHeaders / Authorization 形状 / canonical 不得含签名后追加的头。
变异验证：`Access=`→`Credential=`、去掉 content-type 参与签名、URI 不补斜杠
—— 三个全部被抓。
★ 修判据自身缺陷：首版探针**自己重算** canonical，导致真实签名被改坏时判据仍绿
（去掉 content-type 的变异存活）。改为让签名函数返回真实中间值，探针直接取用。
## 文档
新增 docs/channels-parity.md：与参考逐平台对齐清单（登录 / 额度 / 推理链路三张表
+ 差分判据表 + 未对齐项按影响排序），未对齐项**明示**而非含糊。
