feat(scheduler): 自动更换编排 + 养机灰度 [tsk_mxEFSvKHX64G]
...
实现 15E 任务：Replacer 状态机（pending→creating→probing→activating→draining_old→done/failed）
+ Grayscale 权重梯度（10→25→50→75→100，每步 6h）。
关键设计：
- Redis JSON 记录（sched:replace:{uuid}）+ SetNX 崩溃安全，防止重复 CreateNode
- 幂等 key：attempt 0 = uuid，retry N = uuid:retry:N
- probePass：国内 ≥2/3 ISP 通过 + 海外 L1 全通，连续 2 Tick 才晋级
- 探活超时 15min → failProbeAttempt → 轮换 provider；3 次失败 → failed + NotifyFault
- StubBreaker（15F 未就绪）；NewReplacer(Config{}) 依赖注入
- 6 个集成测试全部通过（happy path / max-retry / crash recovery / queue idempotency / grayscale）

feat(detect): 判定引擎 signals+rules+streak (tsk_OYEiDCzM9_0Y)
...
新建 server/internal/scheduler/detect/ 包，实现任务 15D：
## 核心模块
**lifecycle.go**
- 定义 LifecycleService Go interface（ListNodes / TransitionStatus / SetWeight /
BumpVersion / GetLoad / GetLoadHistory），供 #5 真实实现，内含乐观锁语义（0 行
受影响即本周期放弃，幂等可重入）
- 提供 MockLifecycle 内存 stub（SetConflict / Events 等测试辅助方法）
**signals.go**
- computeSignals：读 SnapshotsByNode，归一化为 NodeSignal
- domesticFailISPs：按 ISP 聚合（stripPrefix "3rd-" 合并 15B/15C 同 ISP 视角），
L3 失败权重最高（L3 挂即记该 ISP 失败，即使 L1/L2 通），无数据 vantage 不计分母
- overseasOK：境外对照点全部 L1 通为真
- trafficDropPct：15min 前后半段在线数降幅百分比
- ProbeSnapshotter interface（解耦 probe.Store，便于 mock）
**rules.go**
- DetectConfig：全量阈值常量（DomesticFailNumerator/Denominator=2/3、
SuspectStreakMin=2、TrafficDropThreshold=80%、TrafficBaselineMin=20、
ConfirmedStreakMin=6、RecoverStreakMin=2、SuspectWeight=10）
- isSuspectTriggered：整数算术避免浮点误差（fail×den >= total×num）
- isFault / effectiveSuspectStreakMin / isTrafficWarning 规则助手
**streak.go**
- StreakStore：Redis hash detect:streak:{node}（fail_streak / suspect_streak /
recover_streak），TTL 2h（宽于 6×5min=30min），进程重启后自动恢复
**engine.go**
- Engine.Tick(ctx)：列举 up/blocked_suspect 节点，按节点依序运行五条规则
- Rule 1 suspect：≥2/3 ISP 失败 + 境外正常 → 连续 2 周期 → up→blocked_suspect，
weight→10，写 probe:freq:{node}=60（1min 提频标记），BumpVersion
- Rule 2 流量预警：trafficDrop≥80% + 基线≥20 → suspect 门槛放宽至 1 周期
- Rule 3 confirmed：blocked_suspect 连续 6 周期 → blocked_confirmed → down（跳过
draining），入队 detect:replace:queue（JSON: nodeId + replacementUuid）
- Rule 4 recover：suspect 期间境内连续 2 周期恢复 → up（weight 交 15E warmup）
- Rule 5 fault：境内+境外同时失败 → 不迁移，调 Notifier.NotifyFault（log stub）
- Notifier interface + LogNotifier stub（15G 就绪前输出 slog.Warn）
**engine_test.go**（19 个测试，全部通过）
- 表驱动覆盖：恰好 2/3 失败、1/3 失败不触发、9min vs 10min streak、
流量预警 1 周期即 suspect、suspect 第 6 周期 confirmed、境内外同挂 fault 不迁移、
恢复 2 周期回 up、3rd- 前缀合并、L3 覆盖 L1/L2
- 乐观锁冲突：SetConflict → 放弃本周期 → 无副作用 → 解冲突后正常重试
- 进程重启：同一 miniredis，新 Engine 读取已存在 streak 继续计数不误清零
- 产出验证：replace queue JSON 结构、probe:freq 标记、weight 变更、事件 detail 字段
**migrations/000010_node_blocked_statuses.{up,down}.sql**
- 扩展 nodes.status ENUM 加入 blocked_suspect / blocked_confirmed

feat(probe): add third-party dial-test adapter for 15C (tsk_-WC9smQK7YRt)
...
Implements ProberAgent interface + Alibaba Cloud CloudMonitor Synthetic adapter:
- ProbeTarget / VantageResult types aligned with 15A schema (L3 always nil)
- AliyunSyntheticAgent: CreateSiteMonitor → poll → map to VantageResult
- ISP vantage uses "3rd-{ISP}" prefix; Redis key probe:{node}:CN:{region}:3rd-*
- Degradation: API error/rate-limit/timeout → skip vantage, log + counter (no write)
- RunOnce(ctx, targets) shape for 15H assembly wiring
- Credentials via cfg only (env-var injection, zero hardcoded secrets)
- 6 new tests (mock vendor server): normalization, rate-limit, timeout, Redis keys,
failed-target L1, no-credentials check; all 22 probe-package tests pass

merge: maestro/tsk_rBPr0Xuy10bz [tsk_rBPr0Xuy10bz] 探针汇聚入口 + Redis 探针存储 (tsk_eu2qVvni1HJR)
...
Manually apply changes from maestro/tsk_rBPr0Xuy10bz that could not be
auto-merged due to uncommitted changes on main at merge time.
Added:
- server/internal/scheduler/probe/types.go – frozen schema types (ReportRequest,
VantagePoint, NodeReport, L1/L2/L3Result, ProbeSnapshot)
- server/internal/scheduler/probe/store.go – Redis Store: SaveReports, CheckAndMarkSeen,
SnapshotsByNode, AliveProbes with TTL constants and key-schema docs
- server/internal/scheduler/probe/ingest.go – IngestHandler (POST /probe/report),
HMAC-SHA256 auth + timestamp window + replay prevention via SetNX
- server/internal/scheduler/probe/ingest_test.go – 17 tests (auth failures, integration,
Store unit tests); all pass with miniredis
Updated:
- server/cmd/server/main.go – register /probe/report route when PROBE_SECRETS env is set
