狀態通知 (Webhooks)
非同步計算任務完成、架構審計通過與風險告警的實時 Webhook 回調機制。
針對長時間非同步計算任務（如大數據集分析、企業架構深度評審），Pinnacle 平台透過 Webhook 機制主動向訂閱端點推送即時事件，避免高頻輪詢。
核心 Webhook 事件清單
| 事件類型 (Event) | 觸發時機 | 負載主要內容 (Payload) |
|---|---|---|
| analytics.job.completed | 非同步分析運算任務正常完成 | job_id, result_summary, execution_duration_ms, metrics |
| analytics.job.failed | 非同步運算過程中出現模型未收斂或超時 | job_id, error_code, error_message, retryable |
| architecture.audit.passed | 企業架構評審通過且未發現嚴重阻斷項 | assessment_id, health_score, tech_debt_hours |
| risk.threshold.exceeded | 實時風險指標超出預設高危閾值 | indicator_code, current_value, threshold_value, severity |
| governance.entity.updated | 離岸實體股權穿透或簽字人變更完成 | entity_id, updated_by, registry_hash |
Webhook 簽名驗證安全機制
為確保回調請求確實源自 Pinnacle 伺服器且未遭中間人竄改，每個 Webhook 請求均攜帶 `X-Pinnacle-Webhook-Signature` 標頭：
Signature = HMAC_SHA256_HEX(WEBHOOK_SECRET, TIMESTAMP + "." + RAW_REQUEST_BODY)
Header: X-Pinnacle-Webhook-Signature: t=1774944000,v1=9f8e7d6c5b4a...多語言 Webhook 接收與驗簽服務代碼
在您的伺服器端部署接收器時，務必在解析 JSON 前提取原始 Raw Body 進行驗簽：
