 - Every user-controlled quantity that becomes a billing multiplier (image `n`, video `seconds`/`duration`, resolution/quality ratios, batch counts) MUST be bounded before it reaches quota calculation. Reject out-of-range values at request validation with a 400. Existing bounds: `dto.MaxImageN` for image generation count, `relaycommon.MaxTaskDurationSeconds` for task video duration, `maxTokensLimit` (`relay/helper/valid_request.go`) for `max_tokens`-family fields on every relay format (OpenAI, Claude, Gemini, Responses). Reuse these constants instead of introducing new ad hoc limits for the same concepts. When adding a new relay format or request DTO, bound its max-tokens and count fields in its validator from day one.
 - Watch for validation bypass paths: passthrough fields (e.g. `Extra["parameters"]`), task `metadata` maps, and multipart form fields can carry the same quantities around the standard DTO validation. Any adaptor that reads a multiplier from such a path must enforce the same bound (or clamp) locally.
 - Durations parsed from media metadata are user/upstream-controlled too: audio file headers (transcription token counting, TTS response duration) and upstream deduction numbers (e.g. Kling `FinalUnitDeduction`) can claim absurd values. Convert them with saturation before they become token counts.
-- Never convert a computed quota or token count to `int` with a bare cast like `int(float64(quota) * ratio)`, `int(math.Round(...))` on unbounded input, or `int(decimal.IntPart())`. All quota rounding/conversion is centralized in `common/quota_math.go`; use those helpers: `common.QuotaFromFloat` (truncating) for float products, `common.QuotaRound` (half-away-from-zero) where rounding is intended, and `common.QuotaFromDecimal` for decimal products. `billingexpr.QuotaRound` delegates to `common.QuotaRound`. Do not reintroduce local conversion helpers or bare casts. Saturation bounds are int32 because quota columns (user/token/log) are 32-bit integers in the database, and every clamp/NaN fallback is logged via `common.SysError` since a single request should never approach those bounds.
+- Never convert a computed quota or token count to `int` with a bare cast like `int(float64(quota) * ratio)`, `int(math.Round(...))` on unbounded input, or `int(decimal.IntPart())`. All quota rounding/conversion is centralized in `common/quota_math.go`; use those helpers: `common.QuotaFromFloat` (truncating) for float products, `common.QuotaRound` (half-away-from-zero) where rounding is intended, and `common.QuotaFromDecimal` for decimal products. `billingexpr.QuotaRound` delegates to `common.QuotaRound`. Do not reintroduce local conversion helpers or bare casts. Single-request saturation stays at the int32 boundary so batch accumulation cannot approach 64-bit wraparound; wallet/top-up conversion uses `common.WalletQuotaFromDecimalStrict` with the JavaScript-safe `common.MaxWalletQuota` boundary. Every clamp/NaN fallback is logged via `common.SysError`.
 - Saturation events are also audited: each helper has a `*Checked` variant (`common.QuotaFromFloatChecked` / `QuotaRoundChecked` / `QuotaFromDecimalChecked`) that additionally returns a `*common.QuotaClamp` when clamping occurred. Billing paths that compute a charge capture that clamp onto `relayInfo.QuotaClamp` (or thread it into task settlement) and, right before writing the consume/task log, call `attachQuotaSaturation` (in `service/log_info_generate.go`) which nests the marker under the log's `other.admin_info.quota_saturation` and emits a request-correlated `logger.LogWarn`. Nesting under `admin_info` makes it admin-only for free (non-admin log views strip `admin_info`). When adding a new billing path, use the `*Checked` variant and surface the clamp the same way so the anomaly stays auditable in both the admin log UI and backend logs.
 - Multiplier maps go through `types.PriceData.AddOtherRatio`, which rejects non-positive, NaN, and +Inf ratios. Do not write to `PriceData.OtherRatios` directly, and do not weaken these guards.
 - Pre-consume (预扣费) and settle (结算/差额) must both be safe: a saturated oversized quota must fail pre-consume with insufficient-quota, never silently wrap. When adding a new billing path (new relay format, new task platform, new adjustment hook), trace the full chain — validation → EstimateBilling/OtherRatios → quota conversion → pre-consume → settle/refund — and confirm each step preserves these invariants.
