- One call per pytest.raises block (S5778): build the guarded start()
before the block and nest the patch outside it.
- The NATS callbacks stay async on purpose: nats-py rejects callbacks
that are not coroutine functions. Comment it and assert it in the
callback test, so nobody drops the async keyword to please S7503.

- GW1: write commands (C2) carry only the server_id; ServerConfigResolver
resolves the connection (command override, live pooled connection,
connectors, opc-servers) with a 60 s cache and a 10 s negative cache.
- GW2: write_status keeps the worst outcome (ok < error < session_bad,
pending/NULL replaced), same rule as the Laborious, built with SQLAlchemy
Core (no SQL formatting).
- GW3: update_write_status never raises; outcome (updated, kept,
row_not_found, invalid, error) logged and counted
(opc_write_status_update_total); runs off the event loop.
- GW4: the reason of a failed write is logged; opc_write_status_by_model
shows the last outcome; a bad timestamp is a failed write, not an
exception.
- GW5: the NATS first connect gives up after 5 s (nats-py's defaults block
the main loop for about 4 minutes while NATS is down); reconnection after
it is unbounded; idle_sweep restarts a connection closed for good; stop()
is safe on a closed connection.

- data_sink.py: _IDENTIFIER_RE uses \w+/re.ASCII instead of the
equivalent-but-verbose [A-Za-z0-9_]+ character class (verified same
match behavior). NOSONAR on update_write_status's 'async with no
await inside' - deliberate, per the ponytail comment already in the
method body (uniform async interface across DataSink, no async pg driver).
- test_grpc_server.py: move make_request() out of the pytest.raises
block so exactly one call can raise the expected exception.
- sonar-project.properties: exclude ingestor/proto/ (generated grpc
code) from analysis - its ReadTag/etc. names are dictated by
grpcio-tools, not a style choice, and renaming them breaks the wire.
