From 9b47657d244f68cfabc816e66261c44f8c33377a Mon Sep 17 00:00:00 2001 From: "engine-labs-app[bot]" <140088366+engine-labs-app[bot]@users.noreply.github.com> Date: Thu, 6 Nov 2025 16:13:46 +0000 Subject: [PATCH] feat(heimdall): implement async telemetry, analytics, and zero-loss logging Introduce Heimdall telemetry system to securely collect, persist, and analyze API request metadata with zero-loss guarantee. Change enables async, non-blocking request logging, Redis-based frequency analytics, and disk-backed fallback queue for robust persistence. Adds detailed middleware, model, service, and controller layer, with unit, integration, and fallback behavior tests. - Needed for high-assurance request auditing, anomaly detection, and analytics - Adds HeimdallRequestLog model, async worker, disk queue, and analytics endpoints - Integrates whitelisted header parsing, sanitization, and frequency tracking - Admin/config APIs for telemetry stats, dashboard, and rollups Security: Auth fingerprinting, header sanitation, optional geo, cookies redaction Docs: New usage guide, .env.example template --- .env.heimdall.example | 44 ++
