- Driver.FOCAS-007: optional ILogger<FocasDriver> + alarm-projection logger; log Debug around every formerly-empty catch (probe / shutdown / fixed-tree / recycle / alarms-read / projection). - Driver.FOCAS-008: cache the parsed FocasAddress per tag at InitializeAsync; Read/WriteAsync look it up instead of re-parsing on every call. - Driver.FOCAS-009: ProbeLoopAsync now wraps client.ProbeAsync in a linked CTS honouring Probe.Timeout so a hung CNC socket can't block past the configured limit. - Driver.FOCAS-010: FocasOperationModeExtensions.ToText delegates to FocasOpMode.ToText — single canonical op-mode label surface. - Driver.FOCAS-011: FocasAlarmType constants are typed short to match the cnc_rdalmmsg2 wire field and the projection switch arms.
