…zone saves
Saving a Claude account from the edit dialog always sends its timezone, so
prepareClaudeTimezoneCredentialUpdateWithHeaders merges a freshly generated
fingerprint (keyed "X-Stainless-OS") with the stored headers, which come back
from the database in canonical casing ("X-Stainless-Os"). The two keys only
differ by case, and whenever the freshly rolled OS differed from the stored
one normalizeCustomHeaders rejected the whole update with
"custom_headers 包含大小写重复且值冲突的请求头: X-Stainless-Os", making two out
of three saves fail.
Canonicalize keys while merging so the stored identity overrides the
generated one on a same-timezone save, as intended.
📝 WalkthroughWalkthroughClaude timezone credential updates now canonicalize merged header names. A regression test verifies that same-timezone saves preserve the stored identity header and avoid duplicate differently cased headers. ChangesClaude timezone header handling
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to Same-timezone Claude credential saves now avoid case-only header conflicts, but credentials containing conflicting retained header variants may silently retain an arbitrary value instead of reporting invalid data. Resolve this validation regression before relying on updates for such records. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

retained baseHeaders before merging or canonicalizing keys, so case-variant
stored keys with differing values are rejected rather than overwritten. Keep
generated-versus-stored identity overwrites handled separately, and preserve
normalizeCustomHeaders for its existing normalization responsibilities.

Preserve duplicate-conflict validation before this merge.
GetCredentialStringMap trims stored keys but does not canonicalize them. Line 290 then overwrites case variants in merged before normalizeCustomHeaders can detect conflicting values. Validate collisions among retained baseHeaders first. Keep generated-versus-stored identity overwrites separate.

Claude 账号的编辑弹窗保存时总会带上
timezone，后端走prepareClaudeTimezoneCredentialUpdateWithHeaders：把新生成的指纹头（键名X-Stainless-OS）与库里读回的既有头（规范大小写X-Stainless-Os）合并。两个键只差大小写，normalizeCustomHeaders视为"大小写重复"，一旦随机到的 OS 与库里不同就整单失败：生产上三次保存约有两次报这个错（OS 在 MacOS/Linux/Windows 三选一）。
修复
合并时先把键名统一成
http.CanonicalHeaderKey，同时区保存时既有身份头按设计覆盖新生成的指纹。测试
新增
TestPrepareClaudeTimezoneUpdate_KeepsCanonicalCasedIdentityOnSameTimezone（循环 30 次覆盖随机 OS），修复前稳定复现同样的报错，修复后go test ./admin全绿。Summary by CodeRabbit
