From db8d666aa1d3150943f30f4158af16f711e10f54 Mon Sep 17 00:00:00 2001 From: serversdown Date: Fri, 29 May 2026 00:56:41 +0000 Subject: [PATCH] settings: add mic_unit_pref for event-report chart MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New UserPreferences field controls the mic channel's unit on the SFM event-detail modal's waveform chart only. "dBL" default, "psi" alternate. Peaks everywhere else (tables, KPI tiles, modal summary) stay in dBL regardless — this is strictly a chart-axis preference. Surfaced as a single dropdown on Settings → General, below the auto-refresh interval. Setting up the storage half ahead of the chart port in the next commit, so the chart can read the value from /api/settings/preferences on first render instead of needing a follow-up wiring pass. Includes idempotent backend/migrate_add_mic_unit_pref.py for fleets already on an older schema.
