## 1. 目的

此計畫把 Monitoring / Alerting / Observability 的事故後回讀從「服務看起來恢復」推進成可重跑、可審查、可拒收的只讀帳本。

它處理的風險不是替正式監控系統下指令，而是先定義未來 owner 必須提供哪些脫敏 ref，才能說明誰改了告警 / receiver / silence、何時異常、改前改後 alert state、receiver 是否真的收到、stale / silence 是否造成 false green、如何 rollback、如何防再發。

本 artifact 不連 live Prometheus、不 reload Alertmanager、不套用 Grafana / SigNoz / Sentry / Langfuse、不 reload OTEL、不改 receiver route、不建立 silence、不送 Telegram、不 fire live alert、不跑 alert chain smoke、不 SSH、不 kubectl、不讀 secret value、不保存 raw alert payload、不寫 production。

## 2. 固定數字

| 指標 | 數值 |
|------|------|
| readback candidate | `60` |
| write-capable candidate | `11` |
| live evidence required candidate | `60` |
| alert rule readback candidate | `13` |
| deploy / reload readback candidate | `6` |
| required readback fields | `30` |
| reviewer checks | `28` |
| outcome lanes | `11` |
| blocked actions | `53` |
| post-incident readback received / accepted | `0 / 0` |
| runtime gate | `0` |

## 3. 必填回讀欄位

每一個候選都必須補齊以下 metadata-only refs，才能進入 reviewer review：

1. incident / change / outage ref。
2. actor role / team attribution ref。
3. change / outage time window ref。
4. change intent 或 break-glass reason ref。
5. before / after alert state refs。
6. rule、datasource、scrape、remote write 或 exporter state ref。
7. receiver route / notification policy / webhook / Telegram route state ref。
8. reload / no-reload ref。
9. receiver receipt readback ref。
10. stale / pending / resolved review ref。
11. silence / mute / dedup / inhibit / maintenance rule review ref。
12. dashboard / trace / log freshness ref。
13. notification delivery metadata ref。
14. alert chain health readback ref。
15. cross-project sync ref。
16. rollback / disable validation ref。
17. post-change monitoring ref。
18. independent postcheck readback ref。
19. recurrence guard ref。
20. maintenance window、rollback owner、followup owner。
21. redacted evidence refs、no-secret-value、no-raw-payload、no-false-green、receipt-not-route-only、independent-postcheck 與 noise-budget / silence-owner attestation。

## 4. Reviewer 檢查

Reviewer 必須確認來源 snapshot 是目前版本，並逐項檢查 actor、時間窗、變更意圖、before / after alert state、rule / datasource / scrape state、receiver route state、reload / no-reload、receiver receipt、stale / silence review、dashboard / trace / log freshness、notification metadata、alert chain health、cross-project sync、rollback、post-change monitoring、independent postcheck、recurrence guard、maintenance window、noise budget owner、脫敏 ref、secret absence、raw payload absence、no-false-green、runtime stays zero 與 count transition safe。

不能把 route `200`、dashboard up、container up、receiver reachable、CD success 或 UI 可見視為告警鏈路驗收。

## 5. 分流

| lane | 用途 |
|------|------|
| `waiting_post_incident_readback` | 尚未收到回讀包；所有 accepted / runtime count 維持 `0` |
| `request_actor_or_time_supplement` | 缺 actor、時間窗、intent 或 break-glass reason |
| `request_alert_state_supplement` | 缺 before / after alert state、rule、datasource、scrape、remote write 或 exporter state |
| `request_receiver_receipt_supplement` | 缺 receiver route state、receipt proof、delivery metadata 或 notification owner |
| `request_stale_silence_supplement` | 缺 stale / pending / resolved、silence、mute、dedup、inhibit 或 maintenance review |
| `request_freshness_or_alert_chain_supplement` | 缺 freshness、alert chain health、post-change monitoring 或 rollback validation |
| `quarantine_raw_payload` | 收到 secret、raw config、raw alert payload、raw receiver payload、未脫敏 log 或截圖時隔離 |
| `reject_false_green_claim` | 把 route 200、dashboard up、container up、receiver reachable、CD success 或 UI 可見當驗收時拒收 |
| `ready_for_monitoring_post_incident_review` | metadata 合格後只能進 reviewer review |
| `recurrence_guard_backfill_required` | 需補防再發 guard、owner review、change freeze、automation block 或 noise budget owner |
| `waiting_runtime_gate` | 即使 readback accepted，runtime gate 仍需獨立人工批准 |

## 6. 固定禁止動作

本階段明確阻擋 `prometheus_reload`、`alertmanager_reload`、`grafana_dashboard_apply`、`signoz_rule_apply`、`sentry_deploy`、`langfuse_config_change`、`otel_collector_reload`、`receiver_route_change`、`silence_policy_change`、`telegram_send`、`notification_route_change`、`webhook_receiver_change`、`remote_write_change`、`exporter_deploy`、`live_alert_fire`、`alert_chain_smoke`、`ssh_read`、`ssh_write`、`kubectl_action`、`secret_value_collection`、`host_write`、`active_scan`、`production_write`、`raw payload storage`、`raw live config storage`、`full receiver payload storage`、`Bot token / DSN / webhook secret collection`、`alert rule / scrape config / dashboard / notification policy / silence / inhibit change` 與任何 action button。

## 7. 目前邊界

此 artifact 只代表事故後回讀計畫已建立。`post_incident_readback_received_count`、`post_incident_readback_accepted_count`、`receiver_receipt_readback_accepted_count`、`stale_pending_resolved_review_accepted_count`、`silence_mute_dedup_inhibit_review_accepted_count`、`alert_chain_health_readback_accepted_count`、`prometheus_reload_authorized_count`、`alertmanager_reload_authorized_count`、`telegram_send_authorized_count`、`alert_chain_smoke_authorized_count`、`runtime_gate_count` 與 `action_button_count` 仍全部維持 `0`。
