From eba77da37ed918c3469d0330bd85dbece74942de Mon Sep 17 00:00:00 2001 From: Nikolas de Hor Date: Fri, 6 Mar 2026 23:21:22 -0300 Subject: [PATCH 1/3] feat(health-check): add Proactive Sentinel for continuous health monitoring Story HCS-3 (Proactive Health Monitoring). The Proactive Sentinel monitors system health continuously and fires alerts before failures cascade: - Register custom watchpoints with configurable check intervals - 5 built-in watchpoints: config integrity, memory files, stale locks, disk space, workspace structure - Alert system with severity levels (info, warning, critical) - Aggregated health score (0-100) from all watchpoints - Consecutive failure tracking for escalation - Alert history persistence in .aiox/sentinel-alerts.json - Start/stop continuous monitoring with timer management - Integration point for HealerManager auto-remediation 50 unit tests covering all features and built-in watchpoints. --- .../core/health-check/proactive-sentinel.js | 651 ++++++++++++++++ .../health-check/proactive-sentinel.test.js | 736 ++++++++++++++++++ 2 files changed, 1387 insertions(+) create mode 100644 .aios-core/core/health-check/proactive-sentinel.js create mode 100644 tests/core/health-check/proactive-sentinel.test.js diff --git a/.aios-core/core/health-check/proactive-sentinel.js b/.aios-core/core/health-check/proactive-sentinel.js new file mode 100644 index 0000000000..b892cc1f9c --- /dev/null +++ b/.aios-core/core/health-check/proactive-sentinel.js @@ -0,0 +1,651 @@ +#!/usr/bin/env node + +/** + * AIOX Proactive Sentinel + * + * Story: HCS-3 - Proactive Health Monitoring + * Epic: Epic 9 - Persistent Memory Layer / Health Check System + * + * Continuously monitors system health indicators and triggers + * preventive actions before failures occur.
