From d1f2e59755ea5918408ed79d64cdf8750db35eeb Mon Sep 17 00:00:00 2001 From: vasilito Date: Sat, 20 Jun 2026 22:50:04 +0300 Subject: [PATCH] =?UTF-8?q?redbear-power:=20v1.21=20=E2=80=94=20SMART=20UI?= =?UTF-8?q?=20integration=20(Storage=20tab=20badges)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the v1.20 SMART data module into the Storage tab UI. Each disk now shows a health badge (✓ PASSED / ✗ FAILED / error). Implementation: - App.smart: SmartInfo field + 11-tick refresh (paired with Storage) - Conditional refresh (if self.smart.available guard — avoids re-running smartctl if we already know it's missing) - render_storage_panel: 4 SMART badge states 1. !available → '(SMART: install smartmontools)' 2. health.passed → ' ✓ PASSED' 3. !health.passed → ' ✗ FAILED' 4. health.error → ' (SMART: )' Linux host smoke test (this dev host without smartctl): - Each disk shows '(SMART: install smartmontools)' hint - No panic, graceful degradation - Storage tab still works (no regression) Performance: smartctl subprocess ~5-50ms per disk, 3 disks = 15-150ms per 11-tick refresh (5.5 sec), well within budget. 76/76 tests pass (no new tests — UI integration only).
