承诺不靠口号兑现：用量稽核、多渠道兜底、自动退款都是线上真实跑着的机制。我们靠长期口碑吃饭，不赚掺水的钱。
These are not slogans: usage audits, multi-channel redundancy and auto-refunds run in production every day. We live on long-term reputation, not padded usage.
每笔调用的 token 明细、缓存命中全量可查；发现上游用量注水，主动稽核、原路退款。
多渠道机制自动兜底；上游中断的请求自动免单或退款。
不偷换模型、不量化阉割，Thinking / 工具调用 / 长上下文原样交付。
对话内容只转发、不留存，日志仅记 token 用量与耗时，用于计费和排障。
Per-request token and cache-hit detail is fully visible. If an upstream pads usage, we audit it and refund the difference.
Multi-channel redundancy keeps requests flowing. Calls dropped upstream are auto-waived or refunded.
No model swapping, no quantized substitutes. Thinking, tool use and long context delivered as-is.
Prompts and completions are relayed, never stored. Logs keep token counts and latency only, for billing and diagnostics.
