fix(web): count only training events for discrimination and split user-stop from validated range

Three collected events with a reserved holdout were stalling because the discriminator door counted holdout. Public selection_allowed still had snapshot fallbacks, and health only proved the image SHA. Co-authored-by: Cursor <cursoragent@cursor.com>

+## BUG-396 | Holdout 门槛、用户停止收口与决策入口未钉死
+
+- 状态：resolved
+- 首次发现：2026-08-26
+- 最近更新：2026-08-26
+- 影响面：training 门槛、`decideRectification`、session_outcome、`/api/health` 数据库版本、Skill 10.0.11 示例
+- 用户现象：3 条事件预留 1 条 holdout 后可能既不能出 Probe 又以为事件够了；用户主动停止被写成已验证完成；健康检查只证明镜像 SHA，不证明迁移已执行。
+- 触发条件：满 2 条即预留 holdout，同时区分门按全部已收事件计 3 条；用户停止与 holdout 通过共用 `completed_with_range`；`/api/health` 只有 `deployment.gitCommit`。
+- 根因：区分门槛把 holdout 算进可评分事件。用户停止与验证通过共用收口状态。公开决策字段仍可能读 snapshot 而不是 reducer。
+- 修复：区分和冲突探针只计 **training** 事件：3 training / 2 training 领域才开门。2 条继续收集；3 条（2 training + 1 holdout）继续收集；4 条（3 training + 1 holdout）才进入区分。用户停止为 `provisional_range_user_stopped`，holdout 通过为 `validated_range`，不得把停止写成已完成验证。GET/点选/刷新/工具投影的 `selection_allowed` 等从 `decideRectification` 派生。`/api/health` 增加 `database.latestMigration` 与 `rectificationContractVersion=v3`。Skill 10.0.11 仍不改写；后续新建 10.0.12 时用 `{timeWindow}/{semanticTarget}/{domain}` 抽象示例。
+- 验证：`tests/test_candidate_discriminator_contract.py`、`frontend/tests/rectification-decide-next-action.test.ts`、`frontend/tests/rectification-decision-authority.test.ts`、`frontend/tests/rectification-hidden-e2e.test.ts`、`frontend/tests/health-deployment.test.ts`。GET `/api/rectification/cases/[caseId]` 的 `latest_result.selection_allowed` 与 `interview` 由 `decideFromDossier` 覆盖，不得回退 snapshot。
+- 防复发：不得用含 holdout 的总事件数开区分门。不得把用户停止标成 `validated_range` 或“最终校正结果”。不得在 interview / answer_choice / turn_decision / Case GET 里独立判断 `selection_allowed`。不得只凭 `gitCommit` 声称迁移已执行。不得原地改 Skill `10.0.11`。后续 Skill `10.0.12` 只用 `{timeWindow}/{semanticTarget}/{domain}`。
+- 相关记录：BUG-394、BUG-395、BUG-393、BUG-366
+- 复发自：BUG-394（holdout 预留后未把门槛改成 training）；BUG-395（staging publish 被 holdout 类型和重复 re-export 挡住）
+- 修复版本：待发布
