📋 基本信息

• 提交者: Account & Model Management Developer (ID: agt_4e45db7841587e235f8a4794)
• 关联任务: tsk_d185bb4a6a15fe5524e10eb4
• 关联需求: req_bc5b7fb980b73c40d4988299
• 目标分支: feature/gap-filling

🎯 背景与动机 (Why)

为 PR #233 合并到 main 前补充缺失的测试覆盖。PR #233 引入了 session 级模型覆盖的 API 端点，但缺少端点级别的测试。

🔧 变更内容 (What)

• (新增): 20 个测试用例覆盖：
• POST /api/sessions/:sessionId/model: 认证(401)、router不可用(503)、session所有权(403)、输入校验(400)、成功路径(200)
• DELETE /api/sessions/:sessionId/model: 认证(401)、router不可用(503)、session所有权(403)、成功路径(204)
• GET /api/sessions/:sessionId/model: 认证(401)、无覆盖(null)、有覆盖(200)、session所有权(403)
• 集成场景: set → get → clear → get 完整生命周期

✅ 验证方式 (How to Verify)

• pnpm lint 通过
• pnpm typecheck 通过
• pnpm test 通过 — 20/20 新测试全部通过

Verification Results

• Tests (new): 20/20 passed ✅
• Regression (org-manager): 1016/1016 passed (38 test files) ✅

• File: packages/org-manager/test/api-model-endpoints.test.ts — 529 additions, single file

Coverage Summary

Endpoint	Tests	Key scenarios
POST /model	9	auth(401), router-unavailable(503), ownership(403), admin-exempt, validation(400×2), success(200), edge cases
DELETE /model	6	auth(401), router-unavailable(503), ownership(403), success(204), admin-exempt, non-existent-override
GET /model	4	auth(401), no-override, with-override, ownership(403)
Lifecycle	1	set → get → clear → get integration

Decision

✅ Approved — Code quality is solid. Test patterns correctly mirror the API endpoint logic. All assertions are specific and meaningful. No spec/doc concerns (pure test-addition task).

⚠️ Per team norms, awaiting Owner merge to feature/gap-filling.
