+# Claude Code Batch Image QA Report
+
+Date: 2026-07-06
+Tester: Claude Code
+Claude model selection:
+
+- Preferred for deep QA: `opus`, but the first run exceeded the initial budget before producing output.
+- Practical model used for this recorded report: `sonnet` with `--safe-mode --effort low`, because it produced a bounded independent QA report at lower cost.
+
+## Original Claude Output
+
+> Batch Image 功能 QA 报告（只读探查）
+>
+> ## 范围
+> 后端计费冻结/结算/退款、状态机与异常兜底、前端批量生图说明文案。基于代码走查(Explore agent)+ 2 条本地 grep 命令验证，未修改任何文件，未执行且未查看任何密钥。
+>
+> ## 执行命令
+>
+> | # | 命令 | 目的 |
+> |---|------|------|
+> | 1 | `grep -n "FOR UPDATE\|Lock(" batch_image_settlement.go batch_image_repo.go` | 验证取消/结算并发是否有行锁保护 |
+> | 2 | `grep -rn "SETTLEMENT_BILLING_FAILED\|enqueueBillingRetry\|MaxRetr" ...` | 验证结算失败重试是否有次数/退避上限 |
+>
+> ## 通过/失败表
+>
+> | 检查项 | 结果 | 依据 |
+> |---|---|---|
+> | 状态转换行锁保护(防止取消/结算竞态) | ✅ 通过 | `batch_image_repo.go:193,322,415` 均用 `SELECT ... FOR UPDATE` |
+> | 结算超额扣费保护 | ✅ 通过 | `batch_image_settlement.go:126-130`，`actualCost > holdAmount` 超万分之一即失败中止 |
+> | 冻结→结算→释放状态机完整性 | ✅ 通过 | 冻结(billing_hold.go) → 结算(settlement.go) → 释放(processor.go:225-239) 链路闭合 |
+> | 僵尸/未提交任务资金释放 | ✅ 通过 | `billing_recovery.go:22-62`，10分钟未提交自动 failed + 释放冻结 |
+> | 非法状态转换保护 | ✅ 通过 | `batch_image.go:356-401` 终态不可逆流转 |
+> | 部分失败正确计费(仅成功项扣费) | ✅ 通过 | `actualCost = successCount * unitPrice` |
+> | 结算失败重试有界（次数/超时上限） | ⚠️ 未证实 | grep 未发现 `MaxRetr`/退避上限，仅见标记 `SETTLEMENT_BILLING_FAILED` 后重新入队，逻辑分散在其他文件未定位到边界 |
+> | 前端费用/取消文案与后端逻辑一致 | ⚠️ 基本一致，措辞有偏差 | 见问题清单 P2 |
+>
+> ## 问题清单（按严重级别）
+>
+> **P1（无，未发现资金泄漏或重复扣款的确认性缺陷）**
+>
+> **P2 – 中**
+> 1. 结算失败重试缺乏可见的次数/超时上限（`SETTLEMENT_BILLING_FAILED` 后 `enqueueBillingRetry`），存在长期卡在 `settling` 状态、资金持续冻结但不释放也不完成结算的风险；需要进一步定位重试调度代码确认是否有兜底超时释放。
+> 2. 前端取消提示文案（"已生成图片仍可能结算扣费"）与后端实际计费口径（以索引完成后统计的成功项为准）表述不完全对齐，可能造成用户对扣费范围的误解，建议澄清措辞而非改变逻辑。
+>
+> **P3 – 低**
+> 3. 结算过程中途宕机（`Settle()` 执行到一半进程重启）依赖外部定时任务/人工介入恢复，未在本次探查中确认是否有自动扫描 `settling` 超时状态的兜底任务。
+>
+> ## 剩余风险
+> - 未验证"结算失败重试"的调度器代码（未在本次两条命令范围内），无法排除无限重试或永久悬挂的可能性。
+> - 未做真实并发压测，行锁存在但未验证高并发下取消+结算同时触发的实际表现（仅代码静态确认加锁点存在）。
+> - 前端文案审查仅基于关键字定位的片段，未通读整个 Guide 组件的所有分支文案。
+>
+> ## 建议后续测试
+> 1. 定位并审查 `enqueueBillingRetry` 实际调度器（重试次数、退避策略、是否有最终告警/人工介入路径），必要时补充单测覆盖"结算持续失败"场景。
+> 2. 编写并发集成测试：同一 batch_id 同时发起"取消"与"结算完成回调"，验证最终状态与金额一致性（是否只释放或只结算一次）。
+> 3. 对 `settling` 状态增加超时巡检的专项测试（类比现有 10 分钟未提交巡检），确认是否已有等价机制，如无需评估是否要补齐。
+> 4. 前端文案走查+产品确认，将"取消后扣费口径"说明与后端"仅索引完成的成功项计费"对齐后再验收。
+
+## Codex Follow-Up Note
+
+Codex spot-checked the first P2 after Claude's report. `enqueueBillingRetry` exists in `batch_image_public.go`, but no obvious max retry or terminal handoff was found in the quick search. Keep this as an open risk for the next implementation/test pass rather than treating it as resolved.

+# Codex Batch Image QA Report
+
+Date: 2026-07-06
+Tester: Codex
+Baseline commits:
+
+- `8fab636 feat: complete batch image workflow`
+- `5553d83 fix: localize antigravity image mapping labels`
+
+## Summary
+
+No blocking issue remains from the Codex-run checks. One frontend regression was found during testing: Antigravity image mapping preset labels displayed English `passthrough` while the existing UI/test expectation used Chinese `透传`. It was fixed in `5553d83`, and the full frontend suite then passed.
+
+## Commands Run
+
+| Area | Command | Result |
+|---|---|---|
+| Backend service tests | Docker Go 1.26.4: `go test ./internal/service -run "BatchImage|AdminService_.*BatchImage|GroupBatchImage|PricingService.*Batch|UsageBilling" -count=1 -timeout=10m` | Pass |
+| Backend repository tests | Docker Go 1.26.4: `go test ./internal/repository -run "BatchImage|UsageBilling|Migrations" -count=1 -timeout=10m` | Pass |
+| Backend server tests | Docker Go 1.26.4: `go test ./internal/server/... -run "APIContract|BatchImage|APIKey" -count=1 -timeout=10m` | Pass |
+| Frontend typecheck | `pnpm --dir frontend typecheck` | Pass |
+| Frontend build | `pnpm --dir frontend build` | Pass |
+| Frontend full tests | `pnpm --dir frontend test:run` | Pass: 128 files, 803 tests |
+| Local HTTP smoke | See `smoke-summary.txt` | Pass |
+
+## HTTP Smoke Result
+
+Source: `smoke-summary.txt`
+
+| Check | Result |
+|---|---|
+| Unauthorized batch list | `401 API_KEY_REQUIRED` |
+| Model list | `200`, 2 models: `gemini-2.5-flash-image`, `gemini-3.1-flash-image` |
+| Insufficient balance submit | `402 BATCH_IMAGE_INSUFFICIENT_BALANCE` |
+| Completed batch detail | `200`, status `completed`, success `2`, fail `0`, actual cost `0.134` |
+| Completed items | `200`, item count `2` |
+| Completed download | `200 application/zip`, 1,602,237 bytes |
+| Balance restoration after smoke | Original `1.86600000 / 0.00000000`; final `1.86600000 / 0.00000000` |
+
+## Findings
+
+| Severity | Finding | Status |
+|---|---|---|
+| P2 | Antigravity batch edit image mapping labels were mixed English/Chinese and failed existing UI expectation. | Fixed in `5553d83`; full frontend tests pass. |
+| P3 | Frontend test output contains existing Vue/i18n warnings (`router-link`, `el-tooltip`, localstorage-file, Browserslist stale data). | Non-blocking; suite passes. |
+
+## Billing And Exception Coverage
+
+Covered by automated tests and smoke:
+
+- Balance reserve moves available funds to frozen funds.
+- Insufficient balance returns 402 before provider submission.
+- Capture rejects actual cost greater than hold.
+- Capture below hold releases the remainder.
+- Stale pre-provider jobs can be failed and released.
+- Completed job download only returns successful outputs.
+
+## Residual Risks
+
+- Real provider failure combinations should still be tested with controlled fake/fixture provider outputs: malformed output JSONL, missing image bytes, provider cancelled after partial success, and delayed output indexing.
+- Concurrent cancel vs settlement needs a dedicated integration test with simultaneous requests to prove row-lock behavior under load, not only unit/static coverage.
+- Settlement billing failure retry currently needs a clearer bounded retry or operator handoff story; Claude independently flagged this too.
+
+## Recommendation
+
+Proceed to broader review with Claude and/or manual exploratory testing. Before production enablement, add one integration test for cancel/settle concurrency and one for persistent settlement billing failure recovery.

+# Batch Image QA Test Case
+
+Date: 2026-07-06
+Branch: `feature/batch-image-foundation`
+
+## Scope
+
+Validate the Sub2API batch image feature before broader external review:
+
+- Gateway API authentication and public response shape
+- Available batch image model listing
+- Balance hold failure path before upstream submission
+- Completed job detail, item listing, and download path
+- Billing hold, release, capture, settlement, and recovery unit coverage
+- Frontend batch image page type/build/test health
+- Agent-copy instruction text for slower polling and resume records
+
+## Test Data
+
+- Local endpoint: `http://127.0.0.1:8080`
+- Local completed batch used for read/download smoke: `imgbatch_8944d988d7b92fcba158a9317fe3e699`
+- No API key or secret is stored in this report.
+
+## Cases
+
+| ID | Case | Expected |
+|---|---|---|
+| BI-API-001 | `GET /v1/images/batches` without key | `401`, `API_KEY_REQUIRED` |
+| BI-API-002 | `GET /v1/images/batches/models` with key | `200`, returns supported image batch models |
+| BI-API-003 | Submit with intentionally insufficient balance | `402`, `BATCH_IMAGE_INSUFFICIENT_BALANCE`, no provider submission |
+| BI-API-004 | Fetch completed batch detail | `200`, terminal status and cost fields present |
+| BI-API-005 | Fetch completed batch items | `200`, success/failure item summary present |
+| BI-API-006 | Download completed successful images | `200 application/zip`, non-empty archive |
+| BI-BILL-001 | Reserve balance hold | Available balance decreases, frozen balance increases |
+| BI-BILL-002 | Capture hold with actual cost below hold | Remainder released, frozen balance returns to zero |
+| BI-BILL-003 | Reject actual cost above hold | Settlement fails before over-capture |
+| BI-BILL-004 | Release stale/unsubmitted hold | Stale job fails and frozen funds are released |
+| BI-FE-001 | Frontend typecheck/build | Pass |
+| BI-FE-002 | Full frontend test suite | Pass |
+| BI-FE-003 | Batch image guide copy text | Includes slower polling and local resume-record requirements |
+
