- Driver.AbCip.Cli-003: SubscribeCommand prints the 'Subscribed' banner BEFORE wiring OnDataChange so the main thread can't interleave its write with the poll-thread handler. - Driver.AbCip.Cli-004: AbCipCommandBase.Timeout and SubscribeCommand validate TimeoutMs / IntervalMs and throw CommandException on non-positive values. - Driver.AbCip.Cli-005: every command now calls FlushLogging() in its finally block. - Driver.AbCip.Cli-006: Timeout init throws NotSupportedException with a pointer at TimeoutMs instead of silently swallowing assignments. - Driver.AbCip.Cli-007: added AbCipCommandBaseTests covering BuildOptions shape, probe / controller-browse / alarm toggles, host address, family selection, tag list passthrough. - Driver.AbCip.Cli-008: rewrote the opening paragraph in docs/Driver.AbCip.Cli.md to credit the six-CLI roster with a pointer at docs/DriverClis.md.
