Editorial analysis
The governance layer as a library: declare what outputs must satisfy, and choose what happens on violation (fix, filter, refuse, escalate). The on-failure vocabulary is the contribution; it maps exactly onto the recovery-behavior axis of our loop model. Validator hub quality varies, core is solid.
Risks
Validators are only as good as their definitions; the hub's community validators need the same review you'd give any dependency.
Evidence notes: Safety: highest safety sub-score in the index; enforcement plus correction strategies, not just detection. Docs: validator authoring guide accurate. Maintenance: steady weekly cadence.
