A failed import scan in gstack's pull request gate used to count as no consumers, so nothing ran. Now it restores the full gate, and labels the file to fix.
Shadow map
Every PR plan now previews a tighter case map, without changing what runs
The map counts only what a case executes: its touchfiles, its test's imports, its skill's shell, the bins its trials invoked
Shadow mode: one line per plan with the cases it would drop and add, and selection stays the same
Replayed over ten days of red PR runs, it kept all 47 failed gate cases

Each plan now carries a shadow line: the checks a tighter map would run, counting only what each case executes. It changes nothing yet. Replayed over ten days of failed runs, it kept every failing case.

Does your own CI run everything when it can't tell what a change touches?

The testing internals doc in the gstack repo covers the shadow map and the fallback rules. So, does your own CI run everything when it can't tell what a change touches?
