# Migration housekeeping

The prior working library, export and ARM binaries are retained under `backup/`.
They are not the threaded release. New source is imported from `atMb-Threaded.export`
and rebuilt in the IDE with a newly built 0.4 C component. Previous IDE caches,
editor lock/options files and C build outputs were omitted from this package.
Git metadata is retained; no commit or push was made.

`RENAMED-MEMBERS.json` is the exact old-to-new mapping for application changes.
The previous transport prefix is removed from active IEC code and comments.
Public request output is now out_errorCode; client output is out_lastErrorCode.
