- Driver.TwinCAT.Cli-001: TwinCATCommandBase.Validate rejects non-positive TimeoutMs / IntervalMs and AmsPort outside 1..65535; ExecuteAsync calls it first. - Driver.TwinCAT.Cli-002: SubscribeCommand serialises every WriteLine through a writeLock to remove the notification-callback vs banner interleave risk. - Driver.TwinCAT.Cli-003: SubscribeCommand.DescribeMechanism derives the banner label from the returned ISubscriptionHandle.DiagnosticId so it can't disagree with what the driver actually did. - Driver.TwinCAT.Cli-004: introduced TwinCATTagCommandBase carrying --poll-only + BuildOptions; BrowseCommand stays on the slimmer TwinCATCommandBase so --poll-only no longer surfaces in browse --help. - Driver.TwinCAT.Cli-005: ProbeCommand --type now carries the 't' short alias to match the other commands. - Driver.TwinCAT.Cli-006: 35 new tests covering Gateway / AmsAddress parse / BuildOptions / PollOnly / browse-helpers / probe-alias / mechanism derivation. - Driver.TwinCAT.Cli-007: replaced the empty-init <inheritdoc/> with an explicit summary warning future maintainers about the no-op init.
