code-reviews: 2026-06-18 re-review of array-write-ergonomics feature at 88915c3

Re-reviewed the 10 modules touched by the MxSparseArray / array-write
ergonomics work (8df5ab3..88915c3). 16 new findings:

- Server-057 (Medium): [] AddItem normalization skips AddItemBulk/AddBufferedItem
- Client.Dotnet-030 (Medium): advise-supervisory missing from IsKnownGatewayCommand (dead command)
- 14 Low: MxSparseArray doc/test gaps, advise-supervisory CLI gaps across clients,
  Client.Java-049 / Client.Python-037 version-bump consistency misses

Worker.Tests and IntegrationTests clean. Worker unchanged by the feature, not re-reviewed.

+### 2026-06-18 re-review (commit `88915c3`)
+
+Scope: `git diff 8df5ab3..88915c3 -- src/ZB.MOM.WW.MxGateway.IntegrationTests/`. One
+commit touched the module: `6b5fe6a` ("fix: resolve code-review findings (locally
+verified)"). The IntegrationTests delta is exactly two hunks in
+`WorkerLiveMxAccessSmokeTests.cs`: (1) a comment reword on the Suspend/Activate block
+(IntegrationTests-031 resolution: "against the advised item" → "against the
+added-but-not-advised item (no Advise was issued between AddItem and this call)"); (2)
+`catch (TimeoutException)` widened to `catch (TimeoutException ex)` and
+`output.WriteLine($"B8: sample-bearing batch predicate timed out: {ex.Message}")` added
+before nulling `bufferedBatch` (IntegrationTests-032 resolution). Both are pure
+comment/diagnostic fixes with no assertion or logic changes. All ten categories clean.
+
+| # | Category | Result |
+|---|---|---|
+| 1 | Correctness & logic bugs | No issues found. Both hunks are comment/diagnostic-only; no assertions, conditions, or API calls changed. |
+| 2 | mxaccessgw conventions | No issues found. Tests remain correctly gated behind `[LiveMxAccessFact]`; no secrets logged; no synthesized events; no direct COM instantiation introduced. |
+| 3 | Concurrency & thread safety | No issues found. No concurrency-relevant code changed. |
+| 4 | Error handling & resilience | No issues found. The `TimeoutException` catch remains non-rethrowing; adding `ex` capture and a `WriteLine` does not affect the error path. |
+| 5 | Security | No issues found. `ex.Message` from `WaitForMessageAsync`'s `TimeoutException` carries only a scan count and timeout duration — no credential data. |
+| 6 | Performance & resource management | No issues found. No new allocations on non-timeout paths; the exception reference capture on the timeout path is negligible. |
+| 7 | Design-document adherence | No issues found. `docs/GatewayTesting.md` was already updated in the same `6b5fe6a` wave (IntegrationTests-030); these two comment fixes require no further doc change. |
+| 8 | Code organization & conventions | No issues found. Comment style is consistent with the surrounding block; no namespace or layout changes. |
+| 9 | Testing coverage | No issues found. No assertions changed; the `output.WriteLine` adds residual diagnostics only. IntegrationTests-033 remains Deferred (AddItem2/Write2 live parity requires the live rig). |
+| 10 | Documentation & comments | No issues found. Both hunks are the documentation fix — the reworded comment now accurately reflects that no `Advise` precedes Suspend/Activate, and the timeout log now surfaces the `WaitForMessageAsync` detail to distinguish the two residual failure modes. |
