hmm no i think it does. the 'Resilience and availability' section is relevant for your question: https://developer.holochain.org/concepts/4_dht/
holochain is completely distributed, so there is no 'offline' and 'online' because there is no third party. it sounds weird writing that but i'm hoping it might challenge you to dig a bit deeper into the docs, because it's there. if not, please come back and let me know so i can pass on feedback about the docs that were unclear or unsatisfactory for you.

from the docs: "Holochain DNAs specify validation rules for every type of entry or link. This empowers agents to check the integrity of the data they see. When called upon to validate data, it allows them to identify corrupt peers and publish a warrant against them. [...] (the DNA is simply a collection of functions for creating, accessing, and validating data.)"
