+## Latest native training-repository compatibility follow-up (`2026-06-30`)
+
+- the next same-family continuation stayed inside the existing
+  `HyperTwistTrainingRepositoryLibrary.cpp` native hardening seam rather than
+  widening product scope:
+  - `UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRepositoryLibrary.cpp`
+- the current local/native loose diff was re-proved on the maintained Windows
+  validation root instead of being left as an unverified ambiguity:
+  - kept the explicit `RightChopInline(..., EAllowShrinking::No)` overload on
+    the accepted-aligned reliable-suffix path
+  - kept the `Completed` switch branch under explicit braces so that queue
+    summary local state remains scoped safely and truthfully inside that case
+- reverse-SSH proof for this exact slice stayed healthy on the primary
+  `localhost:22022` lane:
+  - `scripts/run-hypertwist-remote-windows-powershell.sh`
+  - `whoami=DESKTOP-KS3VGHU\Anthracite Ace`
+  - `hostname=DESKTOP-KS3VGHU`
+  - `scripts/run-hypertwist-remote-windows-file-sync.sh --file UnrealHyperTwist/Source/UnrealHyperTwist/Private/HyperTwistTraining/HyperTwistTrainingRepositoryLibrary.cpp`
+  - synced into maintained root
+    `C:\HyperTwist_worktrees\phase10validate\UnrealHyperTwist\Source\UnrealHyperTwist\Private\HyperTwistTraining\HyperTwistTrainingRepositoryLibrary.cpp`
+    with matching SHA-256
+  - `scripts/run-hypertwist-remote-unreal-build.sh`
+  - maintained root `C:\HyperTwist_worktrees\phase10validate`
+  - `Result: Succeeded`
+  - UnrealBuildTool `Total execution time: 199.69 seconds`
+- current truthful reading after this native follow-up:
+  - the remaining local training-repository seam is no longer an unverified
+    post-packet leftover
+  - the current maintained Windows Unreal lane accepts this repository-library
+    compatibility/scope packet cleanly
+  - the next worthwhile continuation can move back to broader production
+    hardening or another bounded training-repository reduction seam instead of
+    carrying this tiny native uncertainty forward
