- Driver.S7-003: ArgumentNullException.ThrowIfNull on the references
argument at the top of ReadAsync / WriteAsync (was reaching .Count
before any null check).
- Driver.S7-005: drop the redundant global::S7.Net.Plc qualifiers in
ReadOneAsync / WriteOneAsync — using S7.Net already covers Plc.
- Driver.S7-009: PollLoopAsync degrades _health to Degraded after
sustained failure and backs off exponentially up to PollBackoffCap;
resets on a healthy tick so an operator can see the loop wedge.
- Driver.S7-010: Dispose runs the synchronous teardown directly with a
bounded WhenAll Wait drain instead of bridging via DisposeAsync().
- Driver.S7-013: reject unsupported S7DataType values (Int64 / UInt64 /
Float64 / String / DateTime) at InitializeAsync so half-implemented
types no longer leak BadNotSupported live nodes into the address space.
