fix(billing): 异步任务退款时同步减少 used_quota - #6795
Conversation
退款时仅恢复了 quota（剩余额度），但未同步减少 used_quota（已用额度）， 导致"总额度"（quota + used_quota）随退款次数持续虚增，超出用户实际充值金额。 修复三处退款路径： - RefundTaskQuota：任务失败完整退款 - RecalculateTaskQuota：差额结算退款分支 - controller/midjourney.go：Midjourney 任务失败退款 新增 model.UpdateUserUsedQuota 公开函数，仅调整 used_quota 不影响 request_count。

WalkthroughMidjourney billing now uses explicit preparation, settlement, and refund helpers. Persisted billing metadata supports token and channel accounting. Refunds and quota recalculations update user and channel usage without changing request counts. ChangesMidjourney billing and quota accounting
Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to This change correctly targets refund accounting, but the current tests can silently skip the intended failure scenarios because trigger IDs are hardcoded separately from test constants, leaving the billing fix insufficiently guarded; misleading preparation-failure logs also reduce triage quality. Merge should wait for the test coupling issue to be corrected or explicitly accepted. Sequence Diagram(s)sequenceDiagram

⚠️ Unverified finding
Sandbox verification was unavailable.Make refund settlement durable and idempotent across all accounting writes.
These paths update funding, token quota, task state, user usage, channel usage, and billing logs in separate best-effort operations. A failure between operations can leave
quota + used_quotainconsistent. Retrying the whole refund can also duplicate the funding refund.
model/user.go#L1391-L1406: return update status to the settlement layer, but do not rely on error propagation alone. Use an idempotent settlement record or outbox.controller/midjourney.go#L216-L220: do not reverseused_quotawhenIncreaseUserQuotafails. Replay the incomplete settlement instead.service/task_billing.go#L181-L182: do not finalize the refund until the user usage reversal is durably recorded.service/task_billing.go#L258-L259: do not apply negative user and channel deltas independently aftertask.UpdateQuota()fails. Replay all components from the same settlement record.Add failure-injection tests for each partial-failure boundary.
As per coding guidelines: “Billing and quota code must never produce a negative charge or credit through overflow or unvalidated input; preserve safety through settlement and refund.” Based on learnings: separate persistence operations do not provide crash recovery; durable recovery requires an idempotent settlement record or outbox.

The trigger SQL hardcodes

Exclude billing fields from full-row Midjourney updates.
RelayMidjourneyNotify uses Save, and UpdateWithStatus writes Select("*"). A stale task loaded before RefundMidjourneyQuota can restore cleared quota, token_id, and billing_channel_id, enabling a duplicate refund. Exclude billing fields from status and notification updates, or add a version/CAS guard to every full-row writer.

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
The preparation-stage error is logged as a consumption error in both Midjourney handlers. PrepareMidjourneyTaskBilling only validates inputs and sets in-memory billing markers; it never charges quota. Both call sites reuse the settlement wording, which misdirects operator triage.
relay/mjproxy_handler.go#L260-L262: change the message inRelaySwapFaceto name the preparation stage, for example "error preparing Midjourney billing".relay/mjproxy_handler.go#L622-L624: apply the same message change inRelayMidjourneySubmit.
