Lock DSC-0066 on Q1-A and Q2-A. Retire AGD-0048 through AGD-0056 into AGD-0069, DEC-0058, and PLN-0137. Published editor diagnostics use the bound frontend language id as source. For PBS that is pbs. The stable compiler code stays in code and is not copied into source. Related locations, phase, and repair payload stay unpublished.
