Verified: restore resolves `Pkcs/9.0.21` with no NU1902/NU1903. Consumers see the fix only after the `0.2.2` release is published. ### GalaxyRepository-008 — Stale documentation: `SnapshotCachePath` default, csproj comment, consumer matrix @@ -374,7 +374,7 @@ _Unresolved._ | Severity | Low | | Priority | P3 | | Category | Documentation & XML docs | -| Status | Open | +| Status | Resolved | | Location | `ZB.MOM.WW.GalaxyRepository/src/ZB.MOM.WW.GalaxyRepository/GalaxyRepositoryOptions.cs:47` | **Description** @@ -406,4 +406,4 @@ silently does not exist on that host, and nothing logs that persistence is off. **Resolution** -_Unresolved._ +Resolved 2026-11-09 in the commit tagged `(scadaproj#47)` (GalaxyRepository `0.2.2`, unpublished) — `SnapshotCachePath` XML doc now says an empty path disables persistence; `GalaxyHierarchySnapshotStore` logs once at Information when `PersistSnapshot` is true but the path is empty (test `Snapshot_store_logs_once_when_persistence_is_enabled_but_path_is_empty`); stale csproj comment removed; CLAUDE.md consumer matrix updated (HistorianGateway + mxaccessgw). diff --git a/code-reviews/README.md b/code-reviews/README.md index 18a2112..15a22ad 100644 --- a/code-reviews/README.md +++ b/code-reviews/README.md @@ -40,7 +40,7 @@ code-reviews/ ## Summary -10 of 10 libraries reviewed. 44 pending findings across all libraries. +10 of 10 libraries reviewed. 38 pending findings across all libraries.
