- buffer 公式从 baseRPM/5 改为 concurrency + maxSessions
  保留 baseRPM/5 作为 floor 向后兼容
- 粘性路径 fallback 新增 [StickyCacheMiss] 结构化日志
  reason: rpm_red / gate_check / session_limit / wait_queue_full / account_cleared
- session_limit 路径跳过 wait queue 重试（RegisterSession 拒绝无副作用）
- 典型配置 buffer 从 3 提升至 13，大幅减少高峰期 Prompt Cache Miss

Add a purple dashed line showing cache hit rate percentage
(cache_read / (cache_read + cache_creation)) on a secondary
right Y-axis (0-100%). Applies to both user and admin dashboards.

feat(antigravity): progressive penalty for consecutive INTERNAL 500 errors

fix(billing): 计费始终使用用户请求的原始模型，而非映射后的上游模型

fix(api-key):软删除apikey后key没有被释放后续无法再自定义相同的key

fix(admin): fix Safari system log select height

fix(i18n): 修复 Sora 存储配置页面表格列头「存储桶」翻译缺失

fix(gateway): normalize gpt-5.4-xhigh for /v1/messages

Feat/add file upload oauth scope

fix(lifecycle): TokenRefreshService Stop() 防重复 close

修复缺少 refresh_token 时被临时停调度

修复重置状态时未清理临时停调度

使用 sync.Once 包裹 close(stopCh)，避免多次调用 Stop() 时
触发 panic: close of closed channel。

当账号配置了模型映射（如 claude-sonnet-4-6 → glm-5.0）时，系统错误地
使用映射后的上游模型名计算费用。由于上游模型（如 glm-5.0）在定价系统中
没有价格配置，导致计费失败后被静默置为 0，用户不被扣费。

修改 forwardResultBillingModel 优先返回请求模型名，并移除 OpenAI 路径
中 BillingModel 字段对计费模型的覆盖逻辑。

Replace charset→base64url double-encoding with standard random
bytes→base64url approach to match official client behavior and avoid
risk control detection.

Align OAuth scopes with upstream Claude Code client which now includes

Cover isAntigravityInternalServerError body matching,
applyInternal500Penalty tier escalation, handleInternal500RetryExhausted
nil-safety and error handling, and resetInternal500Counter paths.

Move constants, detection, and penalty functions from
antigravity_gateway_service.go to antigravity_internal500_penalty.go.
Fix gofmt alignment and replace hardcoded duration strings with
constant references.

Move the reset logic after urlFallbackLoop so it covers both direct
success and smart retry (429/503) success paths.

When an antigravity account returns 500 "Internal error encountered."
on all 3 retry attempts, increment a Redis counter and apply escalating
penalties:
- 1st round: temp unschedulable 10 minutes
- 2nd round: temp unschedulable 10 hours
- 3rd round: permanently mark as error

Counter resets on any successful response (< 400).

The `admin.settings.soraS3.columns.bucket` key was used in
DataManagementView.vue but missing from both en.ts and zh.ts locale
files, causing the raw translation key to be displayed as a column
header instead of the localized text.

fix(openai): OpenAI 隐私模式全场景覆盖 & 修复转发路径 system prompt 丢失

docs: add Japanese README

injectClaudeCodePrompt 和 systemIncludesClaudeCodePrompt 的 type switch
无法匹配 json.RawMessage 类型（Go typed nil 陷阱），导致 ForwardAsResponses
和 ForwardAsChatCompletions 路径中用户 system prompt 被替换为仅 Claude Code
banner。新增 normalizeSystemParam 将 json.RawMessage 转为标准 Go 类型。
