Giuseppe Destefanis, Matteo Vaccargiu, Roberto Tonelli, Ronnie de Souza Santos, Sabrina Aufiero, Silvia Bartolucci

In Kubernetes, alignment between pull request labels and modified files leads to fewer review participants for core developers but more for newcomers.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Label-diff congruence influences how collaboration unfolds during review, supporting efficiency for experienced developers and visibility for newcomers.

C2weakest assumption

That the observed associations between congruence levels and review characteristics (participant count, discussion) reflect meaningful behavioral effects rather than being driven by unmeasured factors such as PR size, complexity, or topic.

C3one line summary

Label-diff congruence between PR labels and file modifications is prevalent (46.6% perfect) and stable in Kubernetes, predicting fewer review participants for core developers but more for one-time contributors.
