AI narrative
Vue.js achieves an outstanding 88/100 — one of the highest scores in the DebtLens public corpus. Merge discipline (95) and hotspot concentration (86) are exemplary. The one area worth flagging is knowledge silos at 64/100: a small maintainer team means critical modules like reactivity and compiler-core concentrate authorship in one or two engineers. For a project of this size the risk is limited, but it would be the first issue to address in a team-expansion scenario. AI Governance is cleanly tracked.
