+- **Hardware-available issue sweep #593-#625 (2026-10-08, OtOpcUa `master` `3baa332d..d898262c`).** Every issue reachable on the
+  sims/docker-dev worked through parallel worktree agents, six adversarial review rounds, fixture runs (AbCip ControlLogix incl. a
+  200-cycle native lease soak, AbLegacy 13/13, opc-plc, Postgres) and a docker-dev live pass. **ScadaBridge-visible:**
+  (1) **#610 server-side array writes** — array nodes are now writable where the driver can write the whole array (Modbus within
+  `maxRegistersPerWrite`, S7 non-Bool/non-wide types, OpcUaClient, Galaxy with a declared `arrayLength`); a numeric CLR list of
+  another element type (ScadaBridge's `int[]`/`double[]`) is converted element-wise, and the whole write is refused
+  `BadTypeMismatch` (nothing sent) if any element is out of range, fractional-to-integer or NaN; wrong length ⇒ `BadTypeMismatch`,
+  `IndexRange` ⇒ `BadWriteNotSupported`; an array to a scalar node is refused only on Modbus/S7. (2) MQTT writes encode the birth's
+  own Sparkplug datatype; unsupported birth types (Array/DataSet/Template) and `Reference` tags now return **`BadNotSupported`**
+  (was `BadNotWritable`). (3) Native-alarm ack on a non-Primary node is refused Bad; a commented re-ack is stored as AddComment.
+  (4) Surgically-added **raw** nodes are now announced (model-change events), so no re-browse is needed. (5) The alarm-history drain
+  is now also gated on the passive half of a replicating LocalDb pair (no more duplicate historian rows). Also: #609 removed drivers no
+  longer keep republishing resilience/health telemetry; FetchAndCache serving from `central-2` live-gated with central-1 down
+  (#619.3). Left open: #600/#601/#606/#613/#619/#622 partials; hardware-only #592/#611/#612/#614-#616.
