# Batch Auto-Import V2 Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** 实现 V2 的 URL + key 批量导入能力，覆盖模型发现、同模型别名归并、重复导入复用、异步确认、最终 gateway 验证、结果 API 与结果页所需状态投影。

**Architecture:** 采用 `BatchImportService + ConfirmationWorker + ValidationService + RunStateStore + ResultProjection` 分层架构。V2 只以 `import_runs / import_run_items / import_run_item_events` 作为运行态真相，旧 `import_batches/*` 仅保留 legacy linkage。重复导入决策基于 `provider_id + api_key_fingerprint + canonical_model_family`，最终可用性只认宿主真实 `/v1/chat/completions`。

**Tech Stack:** Go 1.22.2、`database/sql` + SQLite、Chi、OpenAPI 3.1、Go `testing`、`httptest`、现有 `internal/host/sub2api` 适配层与 `tests/integration` 集成测试套件。

---

## 0. 实施约束

- 只通过宿主 HTTP API 工作，不直写宿主数据库。
- 所有状态枚举、字段名、API 路由必须遵循当前 canonical contract。
- 每个任务都先写失败测试，再做最小实现，再跑验证。
- 每个任务独立提交，避免大而混杂的 commit。
- 任何 UI/API 展示都只能读 V2 canonical state，不得回退到日志拼接。

## 1. 任务总览

```text
T1  Canonical types and enums
T2  Probe models + alias normalization + canonical family
T3  Capability profile + smoke completion routing
T4  Provider ID + reuse policy
T5  Run/item/event state store repositories
T6  BatchImportService: Stage 0~2
T7  ConfirmationWorker + retry + lease
T8  ValidationService + access status
T9  ResultProjection
T10 HTTP API: runs/items

```

## 2. 设计还原验证矩阵

### 2.1 目标覆盖矩阵

| 设计目标 | 对应任务 | 验证方式 |
|---|---|---|
| URL + key 自动发现模型 | T2, T6, T12 | `/v1/models` 拉取、集成测试 |
| 模型纠错与别名归一化 | T2, T4, T9, T12 | unit + item detail projection |
| 同模型跨中转快速识别 | T2, T4, T12 | `canonical_model_family` 测试 |
| 重复导入自动复用 | T4, T6, T9, T12 | reuse decision + projection |
| 已启用重复账号直接复用 | T4, T6, T9, T12 | `matched_account_state=active` |
| 已停用/已弃用账号快速启用 | T4, T6, T7, T9, T12 | `account_resolution=reactivated` |
| transport + model capability profile | T3, T9, T10, T12 | profile persistence + API schema |
| channel/account 演化 | T6, T12 | patch contract + host stub |
| 异步确认与重试 | T7, T12 | lease/retry/event trail |
| gateway completion 最终判定 | T8, T12 | `access_status` 唯一写入 |
| 结果 API 与结果页数据源 | T5, T9, T10, T12 | run/item/event projection |
| 单一状态源 | T5, T7, T8, T9 | 只读 `import_runs/*` |

### 2.2 契约覆盖矩阵

| 契约 | 对应任务 |
|---|---|
| `run_id / item_id / provider_id` | T1, T4, T5 |
| `run.state` | T1, T5, T9 |
| `current_stage / confirmation_status / access_status` | T1, T5, T7, T8 |
| `matched_account_state / account_resolution` | T4, T5, T6, T9, T10 |
| `api_key_fingerprint` | T4, T5, T6 |
| `canonical_model_families` | T2, T4, T5, T9, T10 |
| `provision_reused / reused_from_*` | T4, T5, T6, T9, T10 |
| `/api/batch-import/runs*` | T10, T12 |

如果 T1~T12 全部完成并通过验证，T13 必须能证明上述矩阵全部为“已覆盖”，否则不得宣称 V2 可按设计实现。

**Step 1: Write the failing audit checklist**

列出必须逐项勾选的设计恢复项：
- 8 项 Objective
- canonical contract
- 结果 API
- migration
- worker/retry/lease
- reuse/reactivation

**Step 2: Run verification to identify gaps**

Run:
```bash
go test ./... -count=1
go test ./tests/integration/... -count=1
go test -cover ./internal/... -count=1
go vet ./...
gofmt -l .
```

Expected: 在实现完成前，这一步用来发现剩余设计缺口；在最终完成时必须全绿。

**Step 3: Write the audit artifact**

将每一项设计要求映射到：
- 代码文件
- 测试文件
- API 路由
- 状态字段

**Step 4: Update board with true gate**

在执行板中明确：
- 哪些任务完成
- 哪些设计要求已还原
- 是否可宣称“V2 设计已被完整实现”

**Step 5: Commit**

```bash
git add docs/2026-05-22-BATCH_AUTO_IMPORT_V2_RESTORATION_CHECKLIST.md docs/EXECUTION_BOARD.md
git commit -m "docs(v2): add restoration checklist and completion gate"
```

## 4. 全局验证门禁

完成 T1~T13 后，必须一次性通过：

```bash
gofmt -l .
go vet ./...
go test ./... -count=1
go test ./tests/integration/... -count=1
go test -cover ./internal/... -count=1
```

额外检查：

- `docs/openapi.yaml` 与 handler 响应字段一致
- `import_runs/*` 足以支撑结果页，不依赖 legacy 表拼接
- `matched_account_state / account_resolution / provision_reused` 能在 item detail 里直接读到
- `canonical_model_family` 能把同模型别名判定为同一族

## 5. 计划完整性结论

这份计划只有在满足以下条件时，才算“任务可以完全还原规划设计”：

1. T1~T12 实现完成并全部通过验证
2. T13 的还原清单中不存在未映射设计项
3. 任一 Objective 都能指向至少一条：
   - 实现任务
   - 自动化测试
   - API 或状态字段证据
4. 结果页/API 不需要额外新增未规划字段才能解释最终状态

如果 T13 审核时发现任何一项设计要求无法映射到任务或测试，这份计划必须回退修改，不能直接进入实现。

## 6. 推荐提交顺序

建议按以下小步提交：

1. `feat(batch): add canonical v2 state enums`
2. `feat(probe): add model discovery and canonical family normalization`
3. `feat(probe): add capability profile and smoke completion routing`
4. `feat(batch): add provider id and reuse policy`
5. `feat(store): complete v2 runtime state repositories`
6. `feat(batch): implement v2 run setup and provision stages`
7. `feat(batch): add confirmation worker and retry handling`
8. `feat(batch): add validation service for final access status`
9. `feat(batch): add result projection for v2 runs and items`
10. `feat(api): add batch import v2 endpoints`
11. `feat(cli): add v2 batch import command`
12. `test(integration): cover batch import v2 flows`
13. `docs(v2): add restoration checklist and completion gate`

Plan complete and saved to `docs/plans/2026-05-22-batch-auto-import-v2-implementation-plan.md`. Two execution options:

**1. Subagent-Driven (this session)** - I dispatch fresh subagent per task, review between tasks, fast iteration

**2. Parallel Session (separate)** - Open new session with executing-plans, batch execution with checkpoints

Which approach?
