 Xiaobao uses two storage shapes: `xiaobao_risk_summaries` keeps one current row per version for fast reads, while `xiaobao_risk_snapshots` stores append-only history for trend analysis.
 
 The AppData migration path is staged through a pure mapper plus preview service. `AppDataV22MigrationService.preview()` reads the allowed `app_data` keys, maps legacy JSON into partition-key-ready rows, and reports row counts plus skipped records before any insert path is enabled.
+
+The first V2.2 read layer is query-first and AppData-compatible. `V22QueryModule` exposes scoped read APIs for version detail, requirement pool, workspace, and Xiaobao warning summaries:
+
+- Version detail reads only the current version's requirements, plans, dev tasks, test cases, and bugs.
+- Requirement pool queries require `productId`, so list/search/filter operations stay on the `requirements.product_id` partition key.
+- Workspace reads only the current user's unfinished plans, dev tasks, test cases, and bugs.
+- Xiaobao warning reads `xiaobao_risk_summaries` first, then maps the precomputed summary into the existing warning UI shape.
+
+During the V2.2 compatibility window, writes still go through the existing AppData stores. The frontend consumes V2.2 relation-table results for render-heavy pages and falls back to AppData only when the V2.2 read is unavailable or empty.

 - Xiaobao precompute storage foundation added: `xiaobao_risk_summaries` stores the current version risk, and `xiaobao_risk_snapshots` stores historical snapshots.
 - Prisma schema now includes the V2.2 relational model skeleton, and the legacy `RequirementService` now uses the `(id, product_id)` composite key.
 - AppData V2.2 migration mapper and preview service added, so legacy JSON can be rehearsed into relation-table rows with counts and skipped-record diagnostics before inserts are enabled.

+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Finish V2.2 by moving high-volume read paths from full AppData document scans to partition-key-scoped relation-table queries, with safe AppData fallback for existing writes.
+
+**Architecture:** Backend exposes read-optimized V2.2 query endpoints for version detail, requirement pool, workspace, and Xiaobao warning summary data. Frontend adds a single mapping layer that converts Prisma-shaped rows into the existing UI types, then pages consume that layer first and fall back to the existing Zustand/AppData stores when the relation tables are unavailable or empty.
+
+**Tech Stack:** Next.js 14 App Router, Zustand, NestJS, Prisma, PostgreSQL partitioned tables, node:test, Jest.

+

+- Create: `apps/web/lib/v22-api.ts`
+- Create: `apps/web/lib/v22-api.test.ts`
+
+- [ ] **Step 1: Write the failing test**
+
+Add `apps/web/lib/v22-api.test.ts` with tests that mock `fetch`, call `loadV22VersionDetailData('version-1')`, and assert:
+
+```ts
+assert.equal(calls[1].url.endsWith('/v2.2/versions/version-1/detail-data'), true);
+assert.equal(result.scope.requirements[0].typeId, 'feature');
+assert.deepEqual(result.scope.requirements[0].platforms, ['web', 'ios']);
+assert.equal(result.scope.devTasks[0].taskNo, 'DEV-001');
+assert.equal(result.scope.devTasks[0].actualStartAt, '2026-01-02T09:00:00.000Z');
+assert.equal(result.scope.testCases[0].caseNo, 'TC-001');

+assert.equal(result.scope.plans[0].owner, 'member-1');
+assert.equal(result.scope.plans[0].startTime, '2026-01-01T00:00:00.000Z');
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `pnpm --filter web test`
+
+Expected: FAIL because `apps/web/lib/v22-api.ts` does not exist.
+
+- [ ] **Step 3: Implement minimal mapping layer**
+
+Create `apps/web/lib/v22-api.ts` exporting:
+
+```ts

+loadV22RequirementsPage(query)
+loadV22WorkspaceData(userId: string)
+loadV22XiaobaoWarnings(query)

+
+The mapper must convert `priority: number` to `P0`-style priorities, `platform` CSV to `platforms[]`, `code` to `taskNo/caseNo/bugNo`, `ownerId` to `owner`, and date-like values to ISO strings.
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `pnpm --filter web test`
+
+Expected: PASS.
+
+### Task 2: Version Detail Hot Path
+
+**Files:**
+- Modify: `apps/web/app/versions/[id]/page.tsx`
+
+- [ ] **Step 1: Write or extend testable helper first**
+
+Use Task 1 mapping tests as the behavior guard for the data shape consumed by the page.
+
+- [ ] **Step 2: Replace full child-data fetches for read-heavy render**
+
+In `apps/web/app/versions/[id]/page.tsx`, load `loadV22VersionDetailData(versionId)` in an effect. Use its returned scope for overview, requirement, plan, dev-task, test-case, and bug tab props when available. Keep the existing stores loaded for overview, members, categories, overtime, drawers, and mutations.
+
+- [ ] **Step 3: Keep fallback behavior**
+
+If the V2.2 request fails or returns an empty relation scope, keep using `buildVersionDataScope(...)` from AppData stores.
+
+- [ ] **Step 4: Verify**
+
+Run: `pnpm --filter web type-check` and `pnpm --filter web test`.
+
+Expected: both exit 0.
+
+### Task 3: Backend And Migration Verification
+
+**Files:**
+- Already modified: `apps/server/src/modules/migration/*`
+- Already created: `apps/server/src/modules/v22-query/*`
+- Modify if needed: `apps/server/src/app.module.ts`
+
+- [ ] **Step 1: Verify Prisma schema**
+
+Run: `pnpm --filter server exec prisma validate --schema prisma/schema.prisma`
+
+Expected: schema validates.
+
+- [ ] **Step 2: Verify backend types and tests**
+
+Run: `pnpm --filter server type-check`
+
+Run from `apps/server`: `$env:NODE_OPTIONS='--max-old-space-size=4096'; .\node_modules\.bin\jest.CMD --runInBand`
+
+Expected: both exit 0.
+
+### Task 4: Documentation And Commit
+
+**Files:**
+- Modify: `docs/architecture.md`
+- Modify: `docs/roadmap.md`
+
+- [ ] **Step 1: Document V2.2 completion boundary**
+
+Update docs to say V2.2 relation tables, import execution, read query API, and version-detail frontend hot path are complete. State that writes still go through AppData during the compatibility window.
+
+- [ ] **Step 2: Final verification**
+
+Run:
+
+```powershell
+pnpm --filter web type-check
+pnpm --filter web test
+pnpm --filter server type-check
+pnpm --filter server exec prisma validate --schema prisma/schema.prisma
+```
+
+Run full backend Jest from `apps/server`.
+
+- [ ] **Step 3: Commit locally**
+
+```powershell
+git add apps/server apps/web docs
+git commit -m "feat(v2.2): 完成高频读取热路径"
+```
+
+Do not push unless the user explicitly asks.
