Replace ASCII-art diagrams across the README and docs/ with editable
.drawio sources plus exported PNGs, so the diagrams render clearly in
rendered markdown and can be maintained/regenerated instead of being
hand-edited as fragile text art. Non-diagram blocks (code, folder
trees, UI wireframes) were left as text.
Retitle from 'SCADA System — Design Documentation' to ScadaBridge; the
overview now describes the repo as the full implementation (src/tests/docker
+ design docs as spec) rather than design docs only. Add Repository Layout
and Build/Test/Run sections. Component table + architecture diagrams unchanged.
Renames the 13 SCADALINK_* runtime env vars → SCADABRIDGE_*, the ScadaLink__
.NET config keys → ScadaBridge__, the stale ScadaLink.Host.exe assembly name
→ ZB.MOM.WW.ScadaBridge.Host.exe, the scadalink_app SQL login → scadabridge_app,
and residual identifiers/comments/docs. Migration records (prior rename
tooling/design, DB-rename helper, this scrub script) carved out.
Adds tools/scrub-scadalink-refs.sh.
The native alarms feature merged with 7 component docs updated, but the
spec layer drifted: HighLevelReqs, Commons, and ManagementService had no
native-alarm coverage and the README table flagged it on only one row.
Add HighLevelReqs §3.4.2 (+ validation), document the Commons
types/entities/messages and the 7 ManagementService commands, sync the
README rows + link the TreeView sub-component, fix 2 broken plan links,
and drop the one-off native-alarms RESUME scratchpad.
The NativeAlarmActor sends SubscribeAlarmsRequest to the DCL manager, but the
manager only routed tag/write/browse messages to the per-connection
DataConnectionActor — alarm subscribe/unsubscribe were unhandled and dead-lettered,
so native alarms never subscribed at runtime. Caught by live T28 deployment.
Mirrors the existing HandleRoute forwarding.
Adds IAlarmSubscribableConnection to MxGatewayDataConnection (shared session-less
feed, ref-counted), IMxGatewayClient.RunAlarmStreamAsync over the package
StreamAlarmsAsync with internal reconnect, and MxGatewayAlarmMapper
(AlarmFeedMessage/OnAlarmTransitionEvent -> NativeAlarmTransition). Behavior
verified against a live gateway in Task 28; mapper unit-tested.
Adds IAlarmSubscribableConnection to OpcUaDataConnection, IOpcUaClient alarm
subscription methods, and RealOpcUaClient A&C event monitored-item +
EventFilter + ConditionRefresh snapshot, mapping fields via OpcUaAlarmMapper.
Behavior verified against a live A&C server in Task 28; mapper unit-tested.
Read-only mirror of native alarm sources into a unified A&C-style state
model (severity + active/acked/shelved/suppressed). Instance-bound source
discovery, site-only SQLite state with live central query (no central
tables), DebugView enrichment. OPC UA A&C events + ConditionRefresh and
MxGateway session-less StreamAlarms via a new IAlarmSubscribableConnection
seam routed connection-level by source reference; new NativeAlarmActor peer
to computed AlarmActor.
