run.stableId

As I understand it, the goal is to bucket together runs of the same type, so that a result management system can:

 

Open a SARIF log file,

Find run.stableId,

Find the most recent run of the same type, and

Copy run.id from the earlier run into run.baselineId of the current run.

 

That doesn’t require namespaced tags. It works whether run.stableId contains "Nightly security tools run/x64 release optimized" or whether it contains "Nightly security tools run x64 release optimized".

 

The only reason you’d need namespacing is if there’s some other scenario that needs to bucket together every "Nightly security tools run", regardless of the build configuration.
