+# G3 P0 Validation Report
+
+> Date: 2026-04-18
+> Scope: `docs/superpowers/plans/2026-04-18-g3-paginated-enrichment-plan.md` Phase 3 -> Phase 4
+> Archetype: `G3 / paginated_enrichment`
+> Result: Passed
+
+## 1. Conclusion
+
+`G3` 的 `P0-3` 基线已经形成正式闭环。
+
+当前 repo-local `P0` 样板 `tests/fixtures/generated_scene/paginated_enrichment` 已经稳定恢复并通过以下关键合同：
+
+1. `main_request`
+2. `pagination_plan`
+3. `enrichment_requests`
+4. `join_keys`
+5. `merge_or_dedupe_rules`
+6. `export_plan`
+
+同时，`G3` 的 `fail-closed` 语义已经固定，至少覆盖：
+
+1. `join_key_missing`
+2. `pagination_incomplete`
+3. `export_only_without_business_chain`
+
+## 2. Validation Inputs
+
+本轮 repo-local `P0` 校验基于以下资产：
+
+1. Fixture:
+   - `tests/fixtures/generated_scene/paginated_enrichment/index.html`
+2. Canonical:
+   - `tests/fixtures/generated_scene/p0_canonical_answers/p0-3-paginated-enrichment.scene-ir.json`
+3. Tests:
+   - `tests/scene_generator_canonical_test.rs`
+   - `tests/scene_generator_test.rs`
+
+关键回归命令：
+
+```powershell
+cargo test --test scene_generator_canonical_test -- --nocapture
+cargo test --test scene_generator_test -- --nocapture
+```
+
+## 3. P0 Restored Semantics
+
+当前 `P0-3` 样板已经稳定恢复：
+
+1. Main request
+   - endpoint url: `http://yx.gs.sgcc.com.cn/marketing/userList`
+   - response path: `rows`
+2. Pagination plan
+   - page field: `page`
+   - page size field: `pageSize`
+   - termination rule: `stop_when_page_rows_empty`
+3. Enrichment request
+   - endpoint url: `http://yx.gs.sgcc.com.cn/marketing/userCharges`
+   - consumed field: `custNo`
+4. Join key
+   - `custNo`
+5. Merge / dedupe rules
+   - `dedupe:custNo`
+   - `aggregate:charge`
+6. Export plan
+   - entry: `exportExcel`
+
+## 4. Acceptance Checklist Result
+
+对照 `WS4 / WS5` 的 `P0` 检查项，当前结果如下：
+
+1. `workflowArchetype = paginated_enrichment`
+2. `mainRequest.responsePath = rows`
+3. `paginationPlan.pageField = page`
+4. `joinKeys = [custNo]`
+5. `mergeOrDedupeRules` 包含 `aggregate:charge`
+6. `exportPlan.entry = exportExcel`
+7. `g3_join_key_resolved = true`
+8. `localhost_dependency_candidate` 未污染主业务链
+9. `readiness.level = A`
+
+## 5. Failure Taxonomy Baseline
+
+本轮已被测试钉住的 `G3` 失败 taxonomy：
+
+1. `join_key_missing`
+2. `pagination_incomplete`
+3. `export_only_without_business_chain`
+
+对应测试：
+
+1. `paginated_enrichment_readiness_marks_join_key_missing_taxonomy`
+2. `paginated_enrichment_readiness_marks_pagination_incomplete_taxonomy`
+3. `paginated_enrichment_readiness_marks_export_only_without_business_chain_taxonomy`
+
+## 6. Final Status
+
+对照 `2026-04-18-g3-paginated-enrichment-plan.md`：
+
+1. `P0 canonical` 已冻结
+2. `P0 acceptance checklist` 已转化为可执行测试
+3. `P0 failure taxonomy` 已形成最小稳定集合
+4. `P0-3` 当前可作为 `G3` 后续 family 扩展的统一校准源
